rmon collection stats
Use the rmon collection stats interface configuration command to collect Ethernet group statistics, which include usage statistics about broadcast and multicast packets, and error statistics about cyclic redundancy check (CRC) alignment errors and collisions. Use the no form of this command to return to the default setting.
rmon collection stats index [owner name]
no rmon collection stats index [owner name]
Syntax Description
index |
Remote Network Monitoring (RMON) collection control index. The range is 1 to 65535. |
owner name |
(Optional) Owner of the RMON collection. |
Defaults
The RMON statistics collection is disabled.

12.1(19)EA1 |
This command was introduced. |
Usage Guidelines
The RMON statistics collection command is based on hardware counters.
Examples
This example shows how to collect RMON statistics for the owner root:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# rmon collection stats 2 owner root
You can verify your setting by entering the show rmon statistics privileged EXEC command.
Related Commands
sdm prefer
Use the sdm prefer global configuration command on the switch to configure the template used in Switch Database Management (SDM) resource allocation. You can use a template to allocate system resources to best support the features being used in your application. Use a template to provide maximum system usage for unicast routing or for VLAN configuration, or to select the dual IPv4 and IPv6 template to support IPv6 forwarding (supported only when the switch is running the advanced IP services image). Use the no form of this command to return to the default template.
sdm prefer {access | default | dual-ipv4-and-ipv6 {default | routing | vlan} | routing | vlan}
no sdm prefer
Syntax Description
Defaults
The default template provides a balance to all features.
Command Modes
Global configuration
Command History
Usage Guidelines
You must reload the switch for the configuration to take effect. If you enter the show sdm prefer command before you enter the reload privileged EXEC command, the show sdm prefer command shows the template currently in use and the template that will become active after a reload.
Use the no sdm prefer command to set the switch to the default desktop template.
The access template maximizes system resources for access control lists (ACLs) as required to accommodate a large number of ACLs.
The default template balances the use of system resources.
Use the sdm prefer vlan global configuration command only on switches intended for Layer 2 switching with no routing. When you use the VLAN template, no system resources are reserved for routing entries, and any routing is done through software. This overloads the CPU and severely degrades routing performance.
Do not use the routing template if you do not have routing enabled on your switch. Entering the sdm prefer routing global configuration command prevents other features from using the memory allocated to unicast routing in the routing template.
Do not use the ipv4-and-ipv6 templates if you do not plan to enable IPv6 routing on the switch. Entering the sdm prefer ipv4-and-ipv6 {default | routing | vlan} global configuration command divides resources between IPv4 and IPv6, limiting those allocated to IPv4 forwarding.
Table 2-15 lists the approximate number of each resource supported in each of the IPv4-only templates for a switch. The values in the template are based on eight routed interfaces and approximately one thousand VLANs and represent the approximate hardware boundaries set when a template is selected. If a section of a hardware resource is full, all processing overflow is sent to the CPU, seriously impacting switch performance.
Table 2-16 lists the approximate number of each resource supported in each of the dual IPv4-and IPv6 templates for a switch.

service password-recovery
Use the service password-recovery global configuration command to enable the password-recovery mechanism (the default). This mechanism allows an end user with physical access to the switch to hold down the Mode button and interrupt the boot process while the switch is powering up and to assign a new password. Use the no form of this command to disable part of the password-recovery functionality. When the password-recovery mechanism is disabled, interrupting the boot process is allowed only if the user agrees to set the system back to the default configuration.
service password-recovery
no service password-recovery
Syntax Description
This command has no arguments or keywords.
Defaults
The password-recovery mechanism is enabled.
Command Modes

12.1(19)EA1 |
This command was introduced. |
Usage Guidelines
As a system administrator, you can use the no service password-recovery command to disable some of the functionality of the password recovery feature by allowing an end user to reset a password only by agreeing to return to the default configuration.
The password-recovery mechanism has been triggered, but
is currently disabled. Access to the boot loader prompt
through the password-recovery mechanism is disallowed at
this point. However, if you agree to let the system be
reset back to the default system configuration, access
to the boot loader prompt can still be allowed.
Would you like to reset the system back to the default configuration (y/n)?
If the user chooses not to reset the system to the default configuration, the normal boot process continues, as if the Mode button had not been pressed. If you choose to reset the system to the default configuration, the configuration file in flash memory is deleted, and the VLAN database file, flash:vlan.dat (if present), is deleted.
Note If you use the no service password-recovery command to control end user access to passwords, we recommend that you save a copy of the config file in a location away from the switch in case the end user uses the password recovery procedure and sets the system back to default values. Do not keep a backup copy of the config file on the switch.
If the switch is operating in VTP transparent mode, we recommend that you also save a copy of the vlan.dat file in a location away from the switch.
You can verify if password recovery is enabled or disabled by entering the show version privileged EXEC command.
Examples
This example shows how to disable password recovery on a switch so that a user can only reset a password by agreeing to return to the default configuration.
Switch(config)# no service-password recovery
Switch(config)# exit

service-policy
Use the service-policy interface configuration command on the switch stack or on a standalone switch to apply a policy map defined by the policy-map command to the input of a physical port or a switch virtual interface (SVI). Use the no form of this command to remove the policy map and port association.
service-policy input policy-map-name
no service-policy input policy-map-name
Syntax Description
input policy-map-name |
Apply the specified policy map to the input of a physical port or an SVI. |
Note Though visible in the command-line help strings, the history keyword is not supported, and you should ignore the statistics that it gathers. The output keyword is also not supported.
Defaults
No policy maps are attached to the port.
Command Modes
Interface configuration
Command History
Usage Guidelines
Only one policy map per ingress port is supported. In software releases earlier than Cisco IOS Release 12.2(25)SE, policy maps can be configured only on physical ports.
In Cisco IOS Release 12.2(25)SE or later, policy maps can be configured on physical ports or on SVIs. When VLAN-based quality of service (QoS) is disabled by using the no mls qos vlan-based interface configuration command on a physical port, you can configure a port-based policy map on the port. If VLAN-based QoS is enabled by using the mls qos vlan-based interface configuration command on a physical port, the switch removes the previously configured port-based policy map. After a hierarchical policy map is configured and applied on an SVI, the interface-level policy map takes effect on the interface.
In software releases earlier than Cisco IOS Release 12.2(25)SE, you can apply a policy map only to the incoming traffic on a physical port. In Cisco IOS Release 12.2(25)SE or later, you can apply a policy map to incoming traffic on a physical port or on an SVI. In Cisco IOS Release 12.2(25)SED or later, you can configure different interface-level policy maps for each class defined in the VLAN-level policy map. For more information about hierarchical policy maps, see the "Configuring QoS" chapter in the software configuration guide for this release.
Classification using a port trust state (for example, mls qos trust [cos | dscp | ip-precedence] and a policy map (for example, service-policy input policy-map-name) are mutually exclusive. The last one configured overwrites the previous configuration.
Examples
This example shows how to apply plcmap1 to an physical ingress port:
Switch(config)# interface gigabitethernet0/1
Switch(config-if)# service-policy input plcmap1
This example shows how to remove plcmap2 from a physical port:
Switch(config)# interface gigabitethernet0/2
Switch(config-if)# no service-policy input plcmap2
This example shows how to apply plcmap1 to an ingress SVI when VLAN-based QoS is enabled:
Switch(config)# interface vlan 10
Switch(config-if)# service-policy input plcmap1
This example shows how to create a hierarchical policy map and attach it to an SVI:

no set {dscp new-dscp | [ip] precedence new-precedence}
Syntax Description
Defaults
No traffic classification is defined.
Command Modes
Policy-map class configuration
Command History
Usage Guidelines
In Cisco IOS Release 12.2(25)SE or later, if you have used the set ip dscp command, the switch changes this command to set dscp in the switch configuration. If you enter the set ip dscp command, this setting appears as set dscp in the switch configuration.
In Cisco IOS Release 12.2(25)SEC or later, you can use the set ip precedence or the set precedence command. This setting appears as set ip precedence in the switch configuration.
The set command is mutually exclusive with the trust policy-map class configuration command within the same policy map.
For the set dscp new-dscp or the set ip precedence new-precedence command, you can enter a mnemonic name for a commonly used value. For example, you can enter the set dscp af11 command, which is the same as entering the set dscp 10 command. You can enter the set ip precedence critical command, which is the same as entering the set ip precedence 5 command. For a list of supported mnemonics, enter the set dscp ? or the set ip precedence ? command to see the command-line help strings.
To return to policy-map configuration mode, use the exit command. To return to privileged EXEC mode, use the end command.
Examples
This example shows how to assign DSCP 10 to all FTP traffic without any policers:
Switch(config)# policy-map policy_ftp
Switch(config-pmap)# class ftp_class
Switch(config-pmap-c)# set dscp 10
Switch(config-pmap)# exit
You can verify your settings by entering the show policy-map privileged EXEC command.

setup express
Use the setup express global configuration command to enable Express Setup mode. Use the no form of this command to disable Express Setup mode.

---|---|
12.1(19)EA1 |
This command was introduced. |
Usage Guidelines
When Express Setup is enabled on a new (unconfigured) switch, pressing the Mode button for 2 seconds activates Express Setup. You can access the switch through an Ethernet port by using the IP address 10.0.0.1 and then can configure the switch with the web-based Express Setup program or the command-line interface (CLI)-based setup program.
When you press the Mode button for 2 seconds on a configured switch, the LEDs above the Mode button start blinking. If you press the Mode button for a total of 10 seconds, the switch configuration is deleted, and the switch reboots. The switch can then be configured like a new switch, either through the web-based Express Setup program or the CLI-based setup program.
Note As soon as you make any change to the switch configuration (including entering no at the beginning of the CLI-based setup program), configuration by Express Setup is no longer available. You can only run Express Setup again by pressing the Mode button for 10 seconds. This deletes the switch configuration and reboots the switch.
If Express Setup is active on the switch, entering the write memory or copy running-configuration startup-configuration privileged EXEC commands deactivates Express Setup. The IP address 10.0.0.1 is no longer valid on the switch, and your connection using this IP address ends.
The primary purpose of the no setup express command is to prevent someone from deleting the switch configuration by pressing the Mode button for 10 seconds.
Examples
This example shows how to enable Express Setup mode:
Switch(config)# setup express
You can verify that Express Setup mode is enabled by pressing the Mode button:
•On an unconfigured switch, the LEDs above the Mode button turn solid green after 3 seconds.
•On a configured switch, the mode LEDs begin blinking after 2 seconds and turn solid green after 10 seconds.
This example shows how to disable Express Setup mode:
Switch(config)# no setup express
You can verify that Express Setup mode is disabled by pressing the Mode button. The mode LEDs do not turn solid green or begin blinking green if Express Setup mode is not enabled on the switch.

This command was introduced. |
12.2(20)SE |
The information in the command output changed, and the user guidelines were updated. |
Usage Guidelines
In releases earlier than Cisco IOS Release 12.2(20)SE, the show auto qos [interface [interface-id]] command output shows the initial generated auto-QoS configuration.
In Cisco IOS Release 12.2(20)SE or later, the show auto qos command output shows only the auto-QoS command entered on each interface. The show auto qos interface interface-id command output shows the auto-QoS command entered on a specific interface.
Use the show running-config privileged EXEC command to display the auto-QoS configuration and the user modifications.
To display information about the QoS configuration that might be affected by auto-QoS, use one of these commands:
•show mls qos
•show mls qos maps cos-dscp
•show mls qos interface [interface-id] [buffers | queueing]
•show mls qos maps [cos-dscp | cos-input-q | cos-output-q | dscp-cos | dscp-input-q | dscp-output-q]
•show mls qos input-queue
•show running-config

Usage Guidelines
This command is available only on the cluster command switch.
If the switch is not a cluster command switch, the command displays an empty line at the prompt.
The SN in the display means switch member number. If E appears in the SN column, it means that the switch is discovered through extended discovery. If E does not appear in the SN column, it means that the switch member number is the upstream neighbor of the candidate switch. The hop count is the number of devices the candidate is from the cluster command switch.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output are not displayed, but the lines that contain Output are displayed.

show controllers ethernet-controller
Use the show controllers ethernet-controller privileged EXEC command without keywords to display per-interface send and receive statistics read from the hardware. Use with the phy keyword to display the interface internal registers or the port-asic keyword to display information about the port ASIC.
show controllers ethernet-controller [interface-id] [phy [detail]] [port-asic {configuration | statistics}] [ | {begin | exclude | include} expression]
Syntax Description
Command Modes
Privileged EXEC (only supported with the interface-id keywords in user EXEC mode)
Command History
|
|
---|---|
12.1(19)EA1 |
This command was introduced. |
Usage Guidelines
This display without keywords provides traffic statistics, basically the RMON statistics for all interfaces or for the specified interface.
When you enter the phy or port-asic keywords, the displayed information is useful primarily for Cisco technical support representatives troubleshooting the switch.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output are not displayed, but the lines that contain Output are displayed.
Examples
This is an example of output from the show controllers ethernet-controller command for an interface. Table 2-19 describes the Transmit fields, and Table 2-20 describes the Receive fields.

Usage Guidelines
Though visible on all switches, the show env temperature status command is valid only for the Catalyst 3560G-48TS, 3560G-48PS, 3560G-24TS, and 3560G-24PS switches. If you enter this command on these switches, the command output shows the switch temperature states and the threshold levels. If you enter the command on a switch other than these four switches, the output field shows Not Applicable.
On a Catalyst 3560G-48PS or 3560G-24PS switch, you can also use the show env temperature command to display the switch temperature status. The command output shows the green and yellow states as OK and the red state as FAULTY. If you enter the show env all command on this switch, the command output is the same as the show env temperature status command output.
For more information about the threshold levels, see the software configuration guide for this release.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output are not displayed, but the lines that contain Output are displayed.

Usage Guidelines
The show interfaces capabilities command with different keywords has these results:
•Use the show interface capabilities module 1 to display the capabilities of all interfaces on the switch. Entering any other number is invalid.
•Use the show interfaces interface-id capabilities to display the capabilities of the specified interface.
•Use the show interfaces capabilities (with no module number or interface ID) to display the capabilities of all interfaces on the switch.
•Use the show interface switchport module 1 to display the switch port characteristics of all interfaces on the switch. Entering any other number is invalid.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output are not displayed, but the lines that contain Output are displayed.

This command was introduced. |
Usage Guidelines
Use the show ip igmp snooping querier command to display the IGMP version and the IP address of a detected device, also called a querier, that sends IGMP query messages. A subnet can have multiple multicast routers but has only one IGMP querier. In a subnet running IGMPv2, one of the multicast routers is elected as the querier. The querier can be a Layer 3 switch.
The show ip igmp snooping querier command output also shows the VLAN and the interface on which the querier was detected. If the querier is the switch, the output shows the Port field as Router. If the querier is a router, the output shows the port number on which the querier is learned in the Port field.
The show ip igmp snooping querier detail user EXEC command is similar to the show ip igmp snooping querier command. However, the show ip igmp snooping querier command displays only the device IP address most recently detected by the switch querier.
The show ip igmp snooping querier detail command displays the device IP address most recently detected by the switch querier and this additional information:
•The elected IGMP querier in the VLAN
•The configuration and operational information pertaining to the switch querier (if any) that is configured in the VLAN
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output do not appear, but the lines that contain Output appear.

In the previous example, this is the IP source guard configuration:
•On the Gigabit Ethernet 0/1 interface, DHCP snooping is enabled on VLANs 10 to 20. For VLAN 10, IP source guard with IP address filtering is configured on the interface, and a binding exists on the interface. For VLANs 11 to 20, the second entry shows that a default port is applied on the interface for the VLANs on which IP source guard is not configured.
•The Gigabit Ethernet 0/2 interface is configured as trusted for DHCP snooping.
•On the Gigabit Ethernet 0/3 interface, DHCP snooping is not enabled on the VLANs to which the interface belongs.
•On the Gigabit Ethernet 0/4 interface, IP source guard with source IP and MAC address filtering is enabled, and static IP source bindings are configured on VLANs 10 and 11. For VLANs 12 to 20, the default port ACL is applied on the interface for the VLANs on which IP source guard is not configured.
•On the Gigabit Ethernet 0/5 interface, IP source guard with source IP and MAC address filtering is enabled and configured with a static IP binding, but port security is disabled. The switch cannot filter source MAC addresses.
This is an example of output on an interface on which IP source guard is disabled:
Switch> show ip verify source gigabitethernet0/6
IP source guard is not configured on the interface gi0/6.

This command was introduced. |
Usage Guidelines
Use the show ipv6 mld snooping querier command to display the MLD version and IPv6 address of a detected device that sends MLD query messages, which is also called a querier. A subnet can have multiple multicast routers but has only one MLD querier. The querier can be a Layer 3 switch.
The show ipv6 mld snooping querier command output also shows the VLAN and interface on which the querier was detected. If the querier is the switch, the output shows the Port field as Router. If the querier is a router, the output shows the port number on which the querier is learned in the Port field.
The output of the show ipv6 mld snoop querier vlan command displays the information received in response to a query message from an external or internal querier. It does not display user-configured VLAN values, such as the snooping robustness variable on the particular VLAN. This querier information is used only on the MASQ message that is sent by the switch. It does not override the user-configured robustness variable that is used for aging out a member that does not respond to query messages.
VLAN numbers 1002 through 1005 are reserved for Token Ring and FDDI VLANs and cannot be used in MLD snooping.
To configure the dual IPv4 and IPv6 template, enter the sdm prefer dual-ipv4-and-ipv6 {default | vlan) global configuration command and reload the switch.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output do not appear, but the lines that contain Output appear.

show mls qos maps
Use the show mls qos maps user EXEC command to display quality of service (QoS) mapping information. During classification, QoS uses the mapping tables to represent the priority of the traffic and to derive a corresponding class of service (CoS) or Differentiated Services Code Point (DSCP) value from the received CoS, DSCP, or IP precedence value.

Usage Guidelines
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output do not appear, but the lines that contain Output appear.
The policed-DSCP, DSCP-to-CoS, and the DSCP-to-DSCP-mutation maps appear as a matrix. The d1 column specifies the most-significant digit in the DSCP. The d2 row specifies the least-significant digit in the DSCP. The intersection of the d1 and d2 values provides the policed-DSCP, the CoS, or the mutated-DSCP value. For example, in the DSCP-to-CoS map, a DSCP value of 43 corresponds to a CoS value of 5.
The DSCP input queue threshold and the DSCP output queue threshold maps appear as a matrix. The d1 column specifies the most-significant digit of the DSCP number. The d2 row specifies the least-significant digit in the DSCP number. The intersection of the d1 and the d2 values provides the queue ID and threshold ID. For example, in the DSCP input queue threshold map, a DSCP value of 43 corresponds to queue 2 and threshold 1 (02-01).
The CoS input queue threshold and the CoS output queue threshold maps show the CoS value in the top row and the corresponding queue ID and threshold ID in the second row. For example, in the CoS input queue threshold map, a CoS value of 5 corresponds to queue 2 and threshold 1 (2-1).

Syntax Description
Command Modes
Privileged EXEC
Command History
Usage Guidelines
When you change the SDM template by using the sdm prefer global configuration command, you must reload the switch for the configuration to take effect. If you enter the show sdm prefer command before you enter the reload privileged EXEC command, the show sdm prefer command shows the template currently in use and the template that will become active after a reload.
The numbers displayed for each template represent an approximate maximum number for each feature resource. The actual number might vary, depending on the actual number of other features configured.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output do not appear, but the lines that contain Output appear.
Examples
This is an example of output from the show sdm prefer command:

This command was introduced. |
Usage Guidelines
If you have used the system mtu or system mtu jumbo global configuration command to change the MTU setting, the new setting does not take effect until you reset the switch.
The system MTU refers to ports operating at 10/100 Mbps; the system jumbo MTU refers to Gigabit ports; the system routing MTU refers to routed ports.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output do not appear, but the lines that contain Output appear.
Examples
This is an example of output from the show system mtu command:
Switch# show system mtu
System MTU size is 1500 bytes
System Jumbo MTU size is 1550 bytes
Routing MTU size is 1500 bytes.

show vlan
Use the show vlan user EXEC command to display the parameters for all configured VLANs or one VLAN (if the VLAN ID or name is specified) on the switch.
show vlan [brief | dot1q tag native | id vlan-id | internal usage | mtu | name vlan-name | private-vlan [type] | remote-span | summary] [ | {begin | exclude | include} expression]

12.2(25)SE |
The dot1q tag native keywords were added. |
Usage Guidelines
In the show vlan mtu command output, the MTU_Mismatch column shows whether all the ports in the VLAN have the same MTU. When yes appears in this column, it means that the VLAN has ports with different MTUs, and packets that are switched from a port with a larger MTU to a port with a smaller MTU might be dropped. If the VLAN does not have an SVI, the hyphen (-) symbol appears in the SVI_MTU column. If the MTU-Mismatch column displays yes, the names of the port with the MinMTU and the port with the MaxMTU appear.
If you try to associate a private VLAN secondary VLAN with a primary VLAN before you define the secondary VLAN, the secondary VLAN is not included in the show vlan private-vlan command output.
In the show vlan private-vlan type command output, a type displayed as normal means a VLAN that has a private VLAN association but is not part of the private VLAN. For example, if you define and associate two VLANs as primary and secondary VLANs and then delete the secondary VLAN configuration without removing the association from the primary VLAN, the VLAN that was the secondary VLAN is shown as normal in the display. In the show vlan private-vlan output, the primary and secondary VLAN pair is shown as non-operational.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output do not appear, but the lines that contain Output appear.

This is an example of output from the show vlan internal usage command. It shows that VLANs 1025 and 1026 are being used as internal VLANs for Fast Ethernet routed ports 23 and 24 on stack member 1. If you want to use one of these VLAN IDs, you must first shut down the routed port, which releases the internal VLAN, and then create the extended-range VLAN. When you start up the routed port, another internal VLAN number is assigned to it.
