Configuring IDSM-2
This chapter contains procedures that are specific to configuring IDSM-2.
Note Catalyst 6500 Series Switch is used generically to refer to both the 6500 series switches and the 7600 series routers.
This chapter contains the following sections:
•Configuration Sequence
•Verifying IDSM-2 Installation
•Configuring the Catalyst 6500 Series Switch for Command and Control Access to IDSM-2
•Configuring the Catalyst Series 6500 Switch for IDSM-2 in Promiscuous Mode
•Configuring the Catalyst Series 6500 Switch for IDSM-2 in Inline Mode
•Administrative Tasks for IDSM-2
•Catalyst and Cisco IOS Software Commands
Configuration Sequence
Perform the following tasks to configure IDSM-2:
1. Configure the Catalyst 6500 series switch for command and control access to IDSM-2.
For the procedure, see Configuring the Catalyst 6500 Series Switch for Command and Control Access to IDSM-2.
2. Log in to IDSM-2.
For the procedure to session to the IDSM-2, see Logging In to IDSM-2.
3. Initialize IDSM-2.
Run the setup command to initialize IDSM-2.
For the procedure, see Initializing the Sensor.
4. Configure IDSM-2 to capture traffic for intrusion analysis.
For the procedures, see Configuring the Catalyst Series 6500 Switch for IDSM-2 in Promiscuous Mode, and Configuring the Catalyst Series 6500 Switch for IDSM-2 in Inline Mode. For the procedure for configuring IDSM-2 to run in promiscuous or inline mode, see Chapter 5 "Configuring Interfaces." For information on the TCP reset interface, see Using the TCP Reset Interface. For the procedure for configuring load balancing for IDSM-2 using Cisco IOS software, see Configuring EtherChanneling.
5. Create the service account.
A service account is needed for password recovery and other special debug situations directed by TAC.
For the procedure, see Creating the Service Account.
Caution You should carefully consider whether you want to create a service account. The service account provides shell access to the system, which makes the system vulnerable. However, you can use the service account to create a new password if the Administrator password is lost. Analyze your situation to decide if you want a service account existing on the system.
6. Perform the other initial tasks, such as adding users, trusted hosts, and so forth.
For the procedures, see Chapter 4 "Initial Configuration Tasks."
7. Configure intrusion prevention.
For the procedures, see Chapter 6 "Configuring Event Action Rules," Chapter 7 "Defining Signatures," and Chapter 10 "Configuring Blocking."
8. Perform miscellaneous tasks to keep IDSM-2 running smoothly.
For the procedures, see Chapter 13 "Administrative Tasks for the Sensor," and Administrative Tasks for IDSM-2.
9. Upgrade the IPS software with new signature updates and service packs.
For more information, see Obtaining Cisco IPS Software.
10. Reimage the application partition and the maintenance partition when needed.
For the procedures, see Installing the IDSM-2 System Image.
Verifying IDSM-2 Installation
Verify that the switch acknowledges IDSM-2 and has brought it online.
To verify the installation, follow these steps:
Step 1 Log in to the console.

Configuring the Catalyst Series 6500 Switch for IDSM-2 in Promiscuous Mode
Traffic is captured for promiscuous analysis on IDSM-2 through SPAN or VACL capture. Port 1 (GigabitEthernet0/1) is used as the TCP reset port, port 2 (GigabitEthernet0/2) is the command and control port, and ports 7 and 8 (GigabitEthernet0/7 and GigabitEthernet0/8) are the monitoring ports. You can configure both monitoring ports to be either SPAN destination ports or VACL capture ports.
Caution If you configure both ports as monitoring ports, make sure that they are configured to monitor different traffic.
Caution You should not configure an IDSM-2 data port as both a SPAN destination port and a VACL capture port, because IDSM-2 will not receive traffic. This dual configuration (SPAN and VACL) causes problems on the switch and traffic is not sent properly.
Note Prior to Catalyst Software 8.4(3), IDSM-2 data ports defaulted to trunking all VLANs. In Catalyst Software 8.4(3) and later, IDSM-2 data ports default to trunking no VLANs. Make sure that the IDSM-2 ports are trunking the proper VLANs, especially if you upgrading from pre-8.4(3) to 8.4(3) or later.
This section contains the following topics:
•Using the TCP Reset Interface
•Configuring SPAN
•Configuring VACLS
•Configuring the mls ip ids Command
Using the TCP Reset Interface
The IDSM-2 has a TCP reset interface—port 1. The IDSM-2 has a specific TCP reset interface because it cannot send TCP resets on its sensing ports.
If you have reset problems with the IDSM-2, try the following:
•If the sensing ports are access ports (a single VLAN), you need to configure the reset port to be in the same VLAN.
•If the sensing ports are dot1q trunk ports (multi-VLAN), the sensing ports and reset port all must have the same native VLAN, and the reset port must trunk all the VLANs being trunked by both the sensing ports.
Configuring SPAN
IDSM-2 can analyze Ethernet VLAN traffic from Ethernet or Fast Ethernet SPAN source ports, or you can specify an Ethernet VLAN as the SPAN source. This section describes how to configure SPAN, and contains the following topics:
•Catalyst Software
•Cisco IOS Software
Catalyst Software
Use the set span command in privileged mode to enable SPAN to IDSM-2.
Note IDSM-2 port numbers are 7 or 8 only.
The following options apply:
•disable—Disables port monitoring.
•module/port—Source module and port numbers.
•vlan—Source VLAN numbers.
•module/port—Destination module and port numbers.
•both—Both receiving and transmitting traffic.
•filter—Applies filter to VLAN.
•inpkts—Enables/disables destination port incoming packets.
•learning—Enables/disables MAC address learning.
•multicast—Enables/disables multicast traffic.
•rx—Receiving traffic.
•session— Session number for SPAN session.
•tx —Transmitting traffic.
To enable SPAN on IDSM-2, follow these steps:
Step 1 Log in to the console.
Step 2 Enter privileged mode:
Step 3 Enable SPAN to IDSM-2:
•From a source port:
cat6k> (enable) set span 3/3 13/7
Direction : transmit/receive
Incoming Packets: disabled
Note Use the filter keyword to monitor traffic on specific VLANs on source trunk ports.
•From a VLAN:
cat6k> (enable) set span 650 13/7 rx
Oper Source : Port 11/1,13/1
Incoming Packets: disabled
Step 4 Show the SPAN sessions:
cat6k> (enable) show span
Oper Source : Port 11/1,13/1
Incoming Packets: disabled
Total local span sessions: 1
Step 5 To disable the SPAN session that is sending traffic to IDSM-2:
cat6k> (enable) set span disable session 1
This command will disable your span session.
Do you want to continue (y/n) [n]? y
Disabled Port 13/7 to monitor receive traffic of VLAN 650
Note For more information on SPAN, refer to the appropriate Catalyst 6500 Series Switch Command Reference.
Cisco IOS Software
Use the monitor session command in global configuration mode to enable SPAN on IDSM-2.
Note Use 1 or 2 for IDSM-2 data port numbers.
The following options apply:
•interface—SPAN source interface
•remote—SPAN source Remote
•vlan— SPAN source VLAN
•GigabitEthernet— GigabitEthernet IEEE 802.3z
•Port-channel— Ethernet Channel of interfaces
•,— Specify another range of interfaces
•--— Specify a range of interfaces
•both— Monitor received and transmitted traffic
•rx— Monitor received traffic only
•tx— Monitor transmitted traffic only
•intrusion-detection-module— SPAN destination intrusion detection module
•destination— SPAN destination interface or VLAN
• filter— SPAN filter VLAN
• source— SPAN source interface, VLAN
• type— Type of monitor session
To enable SPAN on IDSM-2, follow these steps:
Step 1 Log in to the console.
Step 2 Enter global configuration mode:
router# configure terminal
Step 3 Set the source interfaces for the monitor session:
router (config)# monitor session (session_number) source interface interface/port_number
[, | - | rx | tx | both]
Example:
router (config)# monitor session 1 source interface GigabitEthernet2/23 both
Step 4 Enable an IDSM-2 data port as a SPAN destination:
router (config)# monitor session (session_number) destination intrusion-detection-module
module_number data-port data_port_number
Example:
router (config)# monitor session 1 destination intrusion-detection-module 9 data-port 1
Step 5 (Optional) To disable the monitor session:
router (config)# no monitor session session_number
Step 6 (Optional) To filter the SPAN session so that only certain VLANs are seen from switch port trunks:
router (config)# monitor session (session_number) {filter vlan {vlan_ID} [, | - ]}
Example:
router (config)# monitor session 1 filter vlan 146
Step 7 Exit configuration mode:
Step 8 To show current monitor sessions:
router # show monitor session session_number
Example:
router # show monitor session 1
Destination Ports : intrusion-detection-module 9 data-port 1
Note For more information on SPAN, refer to the appropriate Catalyst 6500 Series Cisco IOS Command Reference.
Configuring VACLS
You can set VACLs to capture traffic for IPS from a single VLAN or from multiple VLANs or from FLexWAN2 ports on the 7600 router when using Cisco IOS software. This section describes how to configure VACLs, and contains the following topics:
•Catalyst Software
•Cisco IOS Software
Catalyst Software
Note Port 1 is set as the TCP reset port. Ports 7 and 8 are the sensing ports and can be configured as security ACL capture ports. By default, in Catalyst Software 8.4(1) and earlier releases, ports 7 and 8 are configured as trunk ports and trunk all VLANs on which a security ACL has been applied with the capture feature. If you want to monitor traffic from specific VLANs only, you need to clear the VLANs that you do not want to monitor so that they are not trunked to ports 7 and 8.
Use the set security acl command to configure security ACL capture ports.
The following options apply:
•ACL—Sets security ACL features
–capture-port—Sets ports for ACL capture
–cram—Sets security ACL cram
–ip —Sets IP security ACL features
–ipx—Sets IPX security ACL features
–mac—Sets MAC security ACL features
–map— Sets security ACL to VLAN mapping
•permit—Specifies packets to forward
•deny—Specifies packets to reject
•redirect—Specifies packets to redirect to ports
•before—Inserts ACE before a specified ace in editbuffer
•capture—Makes a copy of this flow in capture ports
•modify— Modifies a specified ACE in editbuffer
To configure VACLs to capture IPS traffic on VLANs, follow these steps:
Step 1 Log in to the console.
Step 2 Enter privileged mode.
Step 3 Create the VACL to capture traffic. Specify what traffic is permitted, denied, and captured:
cat6k> (enable) set security acl ip acl_name permit ip [permit (...) | deny (...)] capture
Note Only permitted traffic can be captured. If you want to permit traffic but not capture it, do no use the capture keyword
Example:
console> (enable) set security acl ip CAPTUREALL permit ip any any capture
CAPTUREALL editbuffer modified. Use 'commit' command to apply changes.
Step 4 Commit the VACL:
console> (enable) commit security acl CAPTUREALL
Committing the VACL writes the VACL and associated ACEs to NVRAM.
Step 5 Map the VACL to the VLANs:
console> (enable) set security acl map acl_name vlan_number
Example:
console> (enable) set security acl map CAPTUREALL 650
ACL CAPTUREALL successfully mapped to VLAN 650.
Step 6 Configure IDSM-2 ports (port 7 or 8) to be capture ports:
console> (enable) set security acl capture module_number/port_number
Example:
console> (enable) set security acl capture 2/7
Successfully set 2/7 to capture ACL traffic.
Note For more information on trunk ports and ACLs, refer to the appropriate Catalyst 6500 Series Switch Command Reference.
Cisco IOS Software
Use the following commands to configure VACLs to capture IPS traffic on VLANs.
The following options apply:
•ip access-list—Named access list
–extended—Extended Access List
–hardware—Enable Hardware Fragment Handling
–log-update—Control access list log updates
–logging—Control access list logging
–resequence—Resequence Access List
–standard—Standard Access List
To configure VACLs to capture IPS traffic on VLANs, follow these steps:
Step 1 Log in to the console.
Step 2 Enter global configuration mode:
router# configure terminal
Step 3 Define the ACL:
router (config)# ip access-list [standard | extended] acl_name
Example:
router(config)# ip access-list standard CAPTUREALL
router(config-std-nacl)# exit
Step 4 Define the VLAN access map:
router(config)# vlan access-map map_name [0-65535]
Step 5 Configure a match clause in a VLAN access map sequence:
router (config-access-map)# match [ip address {1-199 | 1300-2699 | acl_name}]
Step 6 Configure an action clause in the VLAN access map sequence to accompany the preceding match clause:
router(config-access-map)# action forward capture
Step 7 Apply the VLAN access-map to the specified VLANs:
router (config)# vlan filter map_name vlan-list vlan_list
Step 8 Configure the IDSM-2 data ports to capture the captured-flagged traffic:
router (config)# intrusion-detection module module_number data-port data_port_number
capture allowed-vlan capture_vlans
Note When the switch is routing traffic, you should configure IDSM-2 to monitor all VLANs being routed. If you apply the VACL to a FlexWan2 port, you need to configure IDSM-2 to monitor all VLANs.
Step 9 Enable the capture function on IDSM-2:
router (config)# intrusion-detection module module_number data-port data_port_number
capture
This example shows the output from the show run command:
intrusion-detection module 4 data-port 1 capture allowed-vlan 450,1002-1005
intrusion-detection module 4 data-port 1 capture
vlan access-map CAPTUREALL 10
match ip address MATCHALL
ip access-list extended MATCHALL
Configuring the mls ip ids Command
This section describes how to use the mls ip ids command to capture IPS traffic, and contains the following topics:
•Catalyst Software
•Cisco IOS Software
Catalyst Software
When you are running the Cisco IOS Firewall on the MSFC, you cannot use VACLs to capture traffic for IDSM-2, because you cannot apply VACLs to a VLAN in which you have applied an IP inspect rule for the Cisco IOS Firewall. However, you can use the mls ip ids command to designate which packets are captured. Packets that are permitted by the ACL are captured. Those denied by the ACL are not captured. The permit/deny parameter does not affect whether a packet is forwarded to destination ports. Packets coming into that router interface are checked against the IPS ACL to determine if they should be captured. The mls ip ids command is applied as part of the MSFC configuration instead of the supervisor configuration. The mls ip ids command only captures incoming traffic. You will need to use the mls ip ids command on both the client-side router interface and server-side router interface, so that both directions of the connection will be captured.
To use the mls ip ids command to capture IPS traffic, follow these steps:
Step 1 Log in to the MSFC.
Step 2 Enter privileged mode:
Step 3 Enter configuration mode:
router# configure terminal
Step 4 Configure an ACL to designate which packets will be captured:
router(config)# ip access-list extended word
Step 5 Select the interface that carries the packets to be captured:
router(config)# interface interface_name
Step 6 Apply the ACL created in Step 4 to the interface selected in Step 5:
router(config-if)# mls ip ids word
Step 7 Log in to the supervisor engine.
Step 8 Enter privileged mode.
Step 9 On the supervisor engine, add the IDSM-2 monitoring port (port 7 or 8) to the VACL capture list:
cat6k> (enable) set security acl capture module_number/port_number
Caution For IDSM-2 to capture all packets marked by the
mls ip ids command, port 7 or 8 of IDSM-2 must be a member of all VLANs to which those packets are routed.
Cisco IOS Software
When you are using ports as router interfaces rather than switch ports, there is no VLAN on which to apply a VACL.
You can use the mls ip ids command to designate which packets will be captured. Packets that are permitted by the ACL will be captured. Those denied by the ACL will not be captured. The permit/deny parameter does not affect whether a packet is forwarded to destination ports. Packets coming into that router interface are checked against the IPS ACL to determine if they should be captured.
To use the mls ip ids command to capture IDS traffic, follow these steps:
Step 1 Log in to the console.
Step 2 Enter global configuration mode:
router# configure terminal
Step 3 Configure an ACL to designate which packets will be captured:
router(config)# ip access-list extended word
Step 4 Select the interface that carries the packets to be captured:
router(config)# interface interface_name
Step 5 Specify the capture VLANs:
router(config)# intrusion-detection module module_number data-port data_port_number
capture allowed-vlan capture_vlans
Example:
router(config)# intrusion-detection module 4 data-port 1 capture allowed-vlan 165
Step 6 Apply the ACL created in Step 4 to the interface selected in Step 5:
router(config-if)# mls ip ids word
Caution For IDSM-2 to capture all packets marked by the
mls ip ids command, data port 1 or data port 2 of IDSM-2 must be a member of all VLANs to which those packets are routed.
Configuring the Catalyst Series 6500 Switch for IDSM-2 in Inline Mode
You can use IDM or the CLI to configure the IDSM-2 to operate in inline mode between two separate VLANs (one VLAN for each side of the IDM-2). To prepare the IDSM-2 for inline mode, you must configure the switch as well as the IDSM-2. Configure the switch first, then configure the IDSM-2 interfaces for inline mode. For the procedure for configuring IDSM-2 to run in promiscuous or inline mode, see Chapter 5 "Configuring Interfaces."
This section contains the following topics:
•Catalyst Software
•Cisco IOS Software
Catalyst Software
You configure IDSM-2 monitoring ports as trunk ports for inline operation for Catalyst software 8.4(1) or later with Supervisor Engine 1a, Supervisor Engine 2, Supervisor Engine 32, or Supervisor Engine 720. Because the native VLAN is the same as the sole VLAN being trunked, the traffic is not 802.1q encapsulated.
Caution For IPS 5.0(1) you can only configure one IDSM-2 for inline mode between two VLANs. This restriction has been removed for IPS 5.0(2).
Caution The default configuration for IDSM-2 ports 7 and 8 is to trunk all VLANs 1 to 4094. If you clear the IDSM-2 configuration (
clear configuration module_number), IDSM-2 will be trunking all VLANs. If the IDSM-2 interfaces are configured for inline, spanning tree loops will likely be created and a storm will occur. A storm is numerous packets looping and never reaching their destination.
To configure the monitoring ports on IDSM-2 for inline mode, follow these steps:
Step 1 Log in to the console.
Step 2 Enter privileged mode.
Step 3 Set the native VLAN for each IDSM-2 monitoring port:
cat6k (enable)> set vlan vlan_number slot_number/port_number
Example:
cat6k (enable)> set vlan 651 9/7
cat6k (enable)> set vlan 652 9/8
Step 4 Clear all VLANs from each IDSM-2 monitoring port except for the native VLAN on each port (651 for port 7 and 652 on port 8):
cat6k (enable)> clear trunk slot_number/port_number vlan_range
Example:
cat6k (enable)> clear trunk 9/7 1-650,652-4094
cat6k (enable)> clear trunk 9/8 1-651,653-4094
Step 5 Enable Bpdu spantree filtering on the IDSM-2 monitoring ports:
cat6k (enable)> set spantree bpdu-filter 6/7-8 enable
Note For IPS 5.0(2), omit this step.
Cisco IOS Software
Note Cisco IOS software 12.2(18)SXE with Supervisor Engine 720 supports only one IDSM-2 inline between two VLANs.
Configure the IDSM-2 monitoring ports as access ports for inline operation.
Note Etherchannelling inline IDSM-2 is not yet supported in Cisco IOS.
To configure inline VLANs, follow these steps:
Step 1 Log in to the console.
Step 2 Enter global configuration mode:
router# configure terminal
Step 3 Create two VLANs, one for each side of the inline IDSM-2:
router(config)# vlan vlan_number
router(config)# name vlan_name
Step 4 Configure an IOS access port for each interface on each inline VLAN, if you have not done so already:
a. Enter global configuration mode:
router# configure terminal
b. Select the IOS interface to be configured:
router(config)# interface interface_name
c. Enter a description so you know what the interface is for:
router(config-if)# description description
d. Configure the interface as a layer 2 switchport:
router(config-if)# switchport
e. Configure the access mode VLAN:
router(config-if)# switchport access vlan vlan_number
f. Configure the interface/port to be an access port:
router(config-if)# switchport mode access
g. Exit global configuration mode:
Step 5 Configure one IDSM-2 data port to be on each of the two VLANs you created in Step 3.
router# configure terminal
router(config)# intrusion-detection module slot_number data-port data_port_number
access-vlan vlan_number
Step 6 Verify the configuration:
Note In these examples, the IDSM-2 in slot 13 is inline between VLANs 661 and 662. The IDSM-2 data port 1 is on VLAN 661 and data port 2 is on VLAN 662.
a. Verify the IDSM-2 intrusion detection settings:
router# show run | include intrusion-detection
intrusion-detection module 13 management-port access-vlan 147
intrusion-detection module 13 data-port 1 access-vlan 661
intrusion-detection module 13 data-port 2 access-vlan 662
b. Verify that the IDSM-2 data port 1 is an access port on VLAN 661:
router# show intrusion-detection module slot_number data-port data_port_number state
Example:
router# show intrusion-detection module 13 data-port 1 state
Intrusion-detection module 13 data-port 1:
Administrative Mode: static access
Operational Mode: static access
Administrative Trunking Encapsulation: dot1q Operational Trunking Encapsulation:
native Negotiation of Trunking: Off Access Mode VLAN: 661 (inline-vlan-1) Trunking
Native Mode VLAN: 1 (default) Trunking VLANs Enabled: NONE Pruning VLANs Enabled:

c. Verify the VLAN number:
router# show vlan id vlan_number
Example:

Configuring EtherChanneling
This section describes how to configure EtherChanneling on IDSM-2 for Cisco IOS software. It contains the following topics:
•Overview
•Enabling EtherChanneling
•Disabling EtherChanneling
•Verifying EtherChanneling
Overview
Supervisor Engines in the Catalyst 6500 series chassis recognize IDSM-2 devices that are running IPS 5.0 as EtherChannel devices. This lets you install up to eight IDSM-2 devices in the same chassis.
The IDSM-2 in the Catalyst 6500 series switch has eight internal ports. Only four of these ports are used. Port 1 is a TCP/IP reset port. Port 2 is the command and control port. Ports 7 and 8 are the sensing ports for Catalyst software and data ports 1 and 2 for Cisco IOS software. The other ports are not used.
The backplane is 1000 Mbps, which is why IDSM-2 shows 1000 Mbps even though it can only handle about 600 Mbps of performance. The EtherChannel feature allows up to eight IDSM-2 devices to participate in the load balancing on either port 7 or port 8.
Note EtherChannel load balancing for IDSM-2 is only supported on Cisco IOS software. Instructions for configuring EtherChannel load balancing on IDSM-2 for Cisco Catalyst software will be provided when the Catalyst release to support it is available.
Enabling EtherChanneling
Note To configure EtherChannel load balancing on IDSM-2, you must install Cisco IOS 12.2(18)SXE and have Supervisor Engine 720. Cisco IOS only supports promiscuous IDSM-2 EtherChanneling using VACL capture (not SPAN or monitor).
An EtherChannel balances the traffic load across the links in an EtherChannel by reducing part of the binary pattern formed from the addresses in the frame to a numerical value that selects one of the links in the channel.
EtherChannel load balancing can use MAC addresses, IP addresses, or Layer 4 port numbers, which can be source or destination or both source and destination addresses or ports. The selected mode applies to all EtherChannels configured on the switch. EtherChannel load balancing can also use MPLS Layer 2 information.
Use the option that provides the balance criteria with the greatest variety in your configuration. For example, if the traffic on an EtherChannel is going only to a single MAC address and you use the destination MAC address as the basis of EtherChannel load balancing, the EtherChannel always chooses the same link in the EtherChannel; using source addresses or IP addresses might result in better load balancing.
For more information on EtherChanneling, refer to Catalyst 6500 Series Cisco IOS Software Configuration Guide, 12.2SX.
To configure EtherChannel load balancing on IDSM-2, follow these steps:
Step 1 Configure each IDSM-2 for promiscuous operation.
For the procedure, see Chapter 5 "Configuring Interfaces."
Note Make sure that all IDSM-2 VACL capture or SPAN or monitor configuration lines have been removed before configuring IDSM-2 EtherChanneling.
Step 2 Log in to the console.
Step 3 Enter global configuration mode:
router# configure terminal
Step 4 Create the VACL:
router(config)# ip access-list extended vacl_name
Step 5 Add any access control entries, for example, permit any any:
router(config-ext-nacl)# permit ip any any
Step 6 Create at least one VLAN access map sequence:
router(config-ext-nacl)# vlan access-map vlan_access_map_name sequence_number
router(config-access-map)# match ip address vacl_name
router(config-access-map)# action forward capture
Step 7 Apply the VLAN access map to the VLAN(s):
router(config-access-map)# vlan filter vlan_access_map_name vlan-list vlan_list
Step 8 For each IDSM-2, add the desired data ports into the desired EtherChannel:
router(config)# intrusion-detection module module_number data-port data_port_number
channel-group channel_number
Each EtherChannel has a numbered port channel interface. You can configure a maximum of 64 port channel interfaces, numbered from 1 to 256.
Step 9 Configure EtherChannel load balancing:
router(config)# port-channel load-balance [dst-ip | dst-mac | dst-port | mpls | src-dst-ip
| src-dst-mac | src-dst-port | src-ip | src-mac | src-port]
The following options apply:
•dst-ip—Destination IP address
• dst-mac—Destination MAC address
• dst-port —Destination TCP/UDP port
• mpls—Load balancing for MPLS packets
• src-dst-ip—Source and destination IP address
• src-dst-mac—Source and destination MAC address
• src-dst-port—Source and destination TCP/UDP port
• src-ip—Source IP address
• src-mac—Source MAC address
• src-port—Source TCP/UDP port
The default is src-dst-ip., which means EtherChannel uses the combination of source and destination IP addresses for its distribution method.
Step 10 Verify the load balancing:
cat6k# show etherchannel load-balance
EtherChannel Load-Balancing Configuration:
EtherChannel Load-Balancing Addresses Used Per-Protocol:
Non-IP: Source XOR Destination MAC address
IPv4: Source XOR Destination IP address
IPv6: Source XOR Destination IP address
Step 11 Set the VLANs to be captured to the EtherChannel:
router(config)# intrusion-detection port-channel channel_number capture allowed-vlan
vlan_list
Step 12 Enable capture to the EtherChannel:
router(config)# intrusion-detection port-channel channel_number capture
Step 13 Exit global configuration mode:
Step 14 To save the changes:
Disabling EtherChanneling
To disable IDSM-2 EtherChanneling, follow these steps:
Step 1 Log in to the console.
Step 2 Enter global configuration mode:
router# configure terminal
Step 3 To remove a single IDSM-2 from the EtherChannel:
router(config)# no intrusion-detection module module_number data-port data_port_number
channel-group channel_number
Step 4 To remove the whole EtherChannel:
Note The VACL capture commands for IDSM-2 will be left.
router(config)# no intrusion-detection module port-channel channel_number
Verifying EtherChanneling
To verify the IDSM-2 EtherChannel configuration, follow these steps:
Step 1 Log in to the console.
Step 2 To see all EtherChannels:
router# show etherchannel
Port-channels: 1 Max Port-channels = 1
Step 3 To see specific EtherChannel status:
router# show etherchannel 1 [summary | detail | port | port-channel | protocol]
Example:
router# show etherchannel 1 summary
Flags: D - down P - in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
U - in use f - failed to allocate aggregator
u - unsuitable for bundling
Number of channel-groups in use: 1
Group Port-channel Protocol Ports
------+-------------+-----------+----------------------------
Step 4 To see the EtherChannel load balance setting:
router# show etherchannel load-balance
EtherChannel Load-Balancing Configuration:
EtherChannel Load-Balancing Addresses Used Per-Protocol:
Non-IP: Source XOR Destination MAC address
IPv4: Source XOR Destination IP address
IPv6: Source XOR Destination IP address
Step 5 To see IDSM-2 data port information:
router# show intrusion-detection module module_number data-port data_port_number state
Intrusion-detection module 11 data-port 2:
Administrative Mode: trunk
Administrative Trunking Encapsulation: dot1q

Administrative Tasks for IDSM-2
This section contains procedures that help you with administrative tasks for IDSM-2. It contains the following topics:
•Enabling Full Memory Tests
•Resetting IDSM-2
Enabling Full Memory Tests
When IDSM-2 initially boots, by default it runs a partial memory test. You can enable a full memory test in Catalyst software and Cisco IOS software. This section describes how to enable full memory tests, and contains the following topics:
•Catalyst Software
•Cisco IOS Software
Catalyst Software
Use the set boot device boot_sequence module_number mem-test-full command to enable a full memory test. The full memory test takes about 12 minutes.
To enable a full memory test, follow these steps:
Step 1 Log in to the console.
Step 2 Enter privileged mode:
Step 3 Enable the full memory test:
cat6k> (enable) set boot dev cf:1 3 mem-test-full
Device BOOT variable = cf:1
Warning: Device list is not verified but still set in the boot string.
console> (enable) set boot dev hdd:1 3 mem-test-full
Device BOOT variable = hdd:1
Warning: Device list is not verified but still set in the boot string.
The set boot device command can either contain cf:1 or hdd:1.
Step 4 Reset IDSM-2.
For the procedure, see Resetting IDSM-2.
The full memory test runs.
Note A full memory test takes more time to complete than a partial memory test.
Cisco IOS Software
Use the hw-module module module_number reset mem-test-full command to enable a full memory test. The full memory test takes about 12 minutes.
To enable a full memory test, follow these steps:
Step 1 Log in to the console.
Step 2 Enable the full memory test:
router# hw-module module 9 reset mem-test-full
Device BOOT variable for reset = <empty>
Warning: Device list is not verified.
Proceed with reload of module?[confirm]
% reset issued for module 9
Step 3 Reset IDSM-2.
For the procedure, see Resetting IDSM-2.
The full memory test runs.
Note A full memory test takes more time to complete than a partial memory test.
Resetting IDSM-2
If for some reason you cannot communicate with IDSM-2 through SSH, Telnet, or the switch session command, you must reset IDSM-2 from the switch console. The reset process requires several minutes.
This section contains the following topics:
•Catalyst Software
•Cisco IOS Software
Catalyst Software
To reset IDSM-2 from the CLI, follow these steps:
Step 1 Log in to the console.
Step 2 Enter privileged mode:
Step 3 Reset IDSM-2 to the application partition or the maintenance partition:
cat6k> (enable) reset module_number [hdd:1 | cf:1]
Note If you do not specify either the application partition (hdd:1 the default) or the maintenance partition (cf:1), IDSM-2 uses the boot device variable.
The following example shows the output of the reset command:
2003 Feb 01 00:18:23 %SYS-5-MOD_RESET: Module 3 reset from console//
Resetting module 3... This may take several minutes.
2003 Feb 01 00:20:03 %SYS-5-MOD_OK: Module 3 is online.
Caution If IDSM-2 is removed from the switch chassis without first being shut down, or the chassis loses power, you may need to reset IDSM-2 more than once. If IDSM-2 fails to respond after three reset attempts, boot the maintenance partition, and perform the instructions for restoring the application partition. For the procedure, see
Installing the IDSM-2 System Image.
Cisco IOS Software
Note The reset process takes several minutes.
To reset IDSM-2 from the CLI, follow these steps:
Step 1 Log in to the console.
Step 2 Reset IDSM-2:
router# hw-module module module_number reset [hdd:1 | cf:1]
Note If you do not specify either the application partition (hdd:1 the default) or the maintenance partition (cf:1), IDSM-2 uses the boot device variable.
This example shows the output of the reset command:
router# hw-module module 8 reset
Device BOOT variable for reset =
Warning: Device list is not verified.
Proceed with reload of module? [confirm]
% reset issued for module 8
