Commands
The following section provides the complete reference pages for all commands listed in this appendix.
access-list
To assign an existing access list to the IP multiplex profile, enter the access-list command. To clear the access list associated with the IP multiplex profile, use the no form of the command.
access-list {{1-199} |{1300-2699} | name}
Syntax Description
Standard access list number to use with the IP multiplex profile. |
|
Extended access list number to use with the IP multiplex profile. |
|
Command Modes
IP multiplexing profile configuration (config-ipmux-profile)
IPv6 multiplexing profile configuration (config-ipmux-profile-v6)
Command History
|
|
---|---|
Usage Guidelines
You must configure an access list for IP multiplexing to work. The access list identifies the traffic to be considered for multiplexing. If you do not configure an access list, then no packets are queued for multiplexing.
If you enter the access-list command again, then the new access list writes over the previously entered access list.You must enter the shutdown and no shutdown commands to make the new access list take effect.
Create an ACL list using the ip access-list or ipv6 access-list command. When you configure an ACL to use with IP multiplexing, filter only traffic based on destination address, destination port, and protocol type. If you configure an ACL with other filter characteristics, unexpected or undesirable multiplexing decisions may occur. If you change an ACL associated with an IP Multiplexing profile, you will be prompted to issue a shutdown/no shutdown to the profile before the new access-list filters take effect.
If you delete an ACL from the profile, IP multiplexing will not send superframes, however it will still accept superframes.
Examples
The following example shows how to configure the ACL routeRTP-SJ as the active ACL to filter packets for IP multiplexing.

Command Modes
IP multiplexing configuration (config-ipmux-profile)
IPv6 multiplexing configuration (config-ipmux-profile-v6)
Command History
|
|
---|---|
Usage Guidelines
You must configure a destination address for the profile in order to use it. If you attempt to issue a no shutdown command when no destination address is configured, you will be prompted to configure a destination address. If a profile is active, you must issue a shutdown command before changing the destination address.
An incoming superframe must match its source and destination addresses to the destination and source addresses, respectively, in the multiplexing profile in order for the superframe to be demultiplexed. If either address does not match, the superframe is ignored.
If you enter the destination command again, then the new address overwrites the previously entered address.
Examples
The following example shows how to configure the IPv6 address FE80::A8BB:CCFF:FE01:5700 as the destination address for superframe packets.
eigrp interface

Command Modes
Interface configuration (config-if)
Command History
|
|
---|---|
This command was integrated into Cisco IOS Release 12.4(15)T. |
Usage Guidelines
This command advertises routing changes for Enhanced Interior Gateway Routing Protocol (EIGRP) traffic only.
The REPLY sent to any QUERY always contains the latest metric information. Exceptions that result in an immediate UPDATE being sent include the following replies:
- A down interface
- A down route
- Any change in metric which results in the router selecting a new next hop
The default value for the change tolerance will be 50 percent of the computed metric. It can be configured in a range of 0 to 100 percent. If the metric change of the interface is not greater (or less) than the current metric plus or minus the specified amount, the change will not result in a routing change, and no update will be sent to other adjacencies.
The default value for the update intervals is 30 seconds. It can be configured in the range from 0 to 64535 seconds. If this option is specified, changes in routes learned though this interface, or in the interface metrics, will not be advertised to adjacencies until the specified interval is met. When the timer expires, any changes detected in any routes learned through the interface, or the metric reported by the interfaces will be sent out.
Examples
Change-based Dampening Example
The following example sets the threshold to 50 percent tolerance routing updates involving VMI interfaces and peers:
Interval-based Dampening Example
The following example sets the interval to 30 seconds at which updates occur for topology changes that affect VMI interfaces and peers:

Usage Guidelines
The Cisco 5930 ESR does not support this comand.
Use the ip r2cp virtual-template command to specify a virtual-template access number for R2CP. When creating a virtual-access interface, R2CP requires this access number for virtual-template selection.
Examples
The following example sets the R2CP virtual-template access number to 224:
manet cache
To configure the number of MANET cached LSA updates and acknowledgments, use the manet cache command in router-configuration mode. To restore the default values, use the no form of this command.
manet cache { update update-value | acknowledgment ack-value }
no manet cache { update | acknowledgment }
Syntax Description
Defaults
Command Modes
Router configuration (config-router)
Command History
|
|
---|---|
When you set the cache size, the router keeps a larger number of temp LSAs and ACKs. If the cache fills up before the timers expire, the LSAs and ACKs are deleted from the cache. In some cases, the deleted ACKs can cause the router to flood 1-hop neighbors because the router no longer knows about the deleted ACKs.
If you increase the size of the cache, you might prevent non-primary relay routes from flooding in the case when ACKs were deleted because the cache became full before the ACK timer expired. Increasing the cache size reduces the amount of memory available for the cache storage.
Assessing How Cache Size Affects Performance
It is difficult to assess the number of times that flooding occurs because LSAs and ACKs have been deleted before the ACK timer expired. Use the show ospfv3 command to compare the current and maximum cache values. Over time, if the two values are very close, it indicates that the cache is filling up faster than the timer expiration is occurring. In that case, increasing the cache size may be helpful.
Examples
The following example uses cache size for the LSA update and LSA ACKs. The manet cache update command optimizes the exchange of the LS database while forming adjacencies with new neighbors in the radio environment. The result is minimized OSPF control traffic and reduced use of radio bandwidth. The ACK cache size improves the dynamic relaying of the LSA update information:
The lines that begin with "LSA cache Disabled" and "ACK cache Disabled" contain the cache size information.

If you do not specify a maximum packet size for multiplexing, the maximum packet size will default to the configured MTU size minus the length of the superframe header (28 bytes for IPv4, 48 bytes for IPv6).
Examples
The following example shows how to configure the maximum packet size that can go into the IP multiplexing profile routeRTP-SJ to 1472 bytes.
mode
To enable VMI to support multicast traffic, use the mode command in interface-configuration mode. To return the interface to the default mode (aggregate), use the no form of this command.

Command History
|
|
---|---|
This command was integrated into Cisco IOS Release 12.4(15)T to support multicast traffic on Virtual Multipoint Interfaces (VMIs). |
Usage Guidelines
Use this command to support multicast traffic in router-to-radio configurations.
Aggregate mode is the default mode for VMI, where VMI aggregates all virtual-access interfaces logically. To enable VMI to forward packets to the correct virtual-access interface, you must define applications such as EIGRP and OSPFv3 (all applications above Layer 2) on VMI.
Using bypass mode is recommended for multicast applications.
In bypass mode, the virtual-access interfaces are directly exposed to applications running above Layer2. In bypass mode, definition of a VMI is still required because the VMI continues to manage presentation of cross-layer signals such as neighbor up, neighbor down, and metrics. However, applications will still be aware on the actual underlying virtual-access interfaces and send packets to them directly.
Using bypass mode can cause databases in the applications to be larger because knowledge of more interfaces are required for normal operation.
After you enter the mode command, Cisco recommends that you copy the running configuration to NVRAM because the default mode of operation for VMI is to logically aggregate the virtual-access interfaces.
Examples
The following examples set the interface mode to bypass:
The following example shows how to enable Multicast Support on a VMI Interface:
Note Enabling Multicast on VMI interfaces includes changing the VMI interface to bypass mode and enabling "ip pim" on the virtual-template interface.

mtu
To specify the maximum transmission unit (MTU) size for an outbound superframe, enter the mtu command. To reset the MTU to 1500 bytes, use the no form of the command.
Syntax Description
MTU size of the outbound superframe in bytes. Valid values range from 256 to 1500 bytes |
Command Default
Command Modes
IP multiplexing configuration (config-ipmux-profile)
IPv6 multiplexing configuration (config-ipmux-profile-v6)
Command History
|
|
---|---|
Usage Guidelines
If you do not specify an MTU size, the IP multiplex packet handler uses the default value of 1500 bytes.
For each new packet being added to the superframe, the IP multiplex packet handler checks the byte count of the multiplex queue. If the queue byte count and the superframe header length exceeds the configured MTU size, it builds a superframe from the previous packets and the new packet becomes the first packet of the next superframe.
If you enter the mtu command again, then the MTU size overwrites the previously entered size.
The superframe size specified in the mtu command includes the IP frame header for the superframe of 48 bytes for IPv4 and 28 bytes for IPv4 packets. Therefore an IPv6 mtu configured to 1400 bytes will accept 1352 bytes of data before sending a full superframe. An IPv4 mtu configured to 1400 bytes will accept 1372 bytes of data before sending a full superframe.
Examples
The following example shows how to configure the MTU size for IP multiplexing profile routeRTP-SJ to 1000 bytes.
ospfv3 area
To attach an interface to a specific OSPFv3 area and enable routing of IPv6 network traffic using IPv4 or IPv6 addresses, use the ospfv3 area command in interface-configuration mode. To detach the interface from the OSPFv3 area, use the no form of this command.
ospfv3 process-id area area-number {ipv4 | ipv6} [instance instance-number]
no ospfv3 [ process-id ] area area-number {ipv4 | ipv6} instance instance-number
Syntax Description

Usage Guidelines
You must enter this command to attach an interface to a specific OSPFv3 process and instance. After you have attached an interface to a specific OSPFv3 process and interface, you can enter other OSPFv3 characteristics.
An interface can only support one IPv4 address family process and one IPv6 address family process at the same time.
Examples
The following example shows a typical configuration with both IPv6 and IPv4 routing in OSPF that use the default instance numbers.
ospfv3 cost dynamic
To specify that the OSPF cost associated with a path on an interface is dynamic, use the ospfv3 cost dynamic command in interface-configuration mode.
ospfv3 [ process-id ] cost dynamic
Syntax Descriptionz
(Optional) Internal identification. It is locally assigned and can be any positive integer. The number used here may be assigned administratively when OSPF routing is enabled.The range is 1 to 65535. |
Command Default
By default, MANET interfaces are set to use dynamic costs. Non-MANET networks are set to use static costs.
Command Modes

no ospfv3 [ process-id ] cost dynamic hysteresis [threshold threshold_value | percent percent_value]
Syntax Description
Command Modes
Interface configuration (config-if)
Command History
|
|
---|---|
Usage Guidelines
Use this command to dampen the frequency of OSPFv3 route cost changes due to small changes in link metrics. The threshold option specifies the magnitude of change in cost before OSPFv3 is notified. The percent option specifies the change relative to the original cost necessary before OSPFv3 is notified.
The n o ospfv3 cost dynamic hysteresis command disables cost dynamic hysteresis. The no ospfv3 cost dynamic hysteresis command with the threshold or percent keywords leaves hysteresis enabled and returns the type and value to their defaults.
If hysteresis is enabled without a mode, the default mode is threshold and the default threshold-value is 10.
The higher the threshold or percent value is set, the larger the change in link quality required to change OSPF route costs.
Examples
The following example sets the cost dynamic hysteresis to 10 percent for OSPFv3 process 4:

ospfv3 manet peering cost
Use selective peering to minimize the full neighbor adjacencies in a MANET. To set a minimum cost change threshold necessary before a new neighbor is considered for selective peering, use the ospfv3 manet peering cost command in interface-configuration mode. To exclude cost considerations from the selective peering decision, use the no form of this command.
ospfv3 [ process-id ] manet peering cost {threshold threshold_value | percent percent_value}
no ospfv3 [ process-id ] manet peering cost
Syntax Description
Command Default
The default MANET peering cost is 0. No incremental improvement in route cost is required to consider selective peering with a new neighbor.
Command Modes
Interface configuration (config-if)
Command History
|
|
---|---|
Usage Guidelines
When selective peering is configured at a given redundancy level, the first 50% of redundant paths do not consider the cost change threshold associated with this command. This allows a minimum OSPFv3 topology to be established in high cost networks.
For example, if you configure selective peering to have a redundancy level of 3 (a total of four paths allowed), the first two neighbors are considered for selective peering, regardless of the neighbor cost. Only the subsequent paths are held to the relative cost change requirements.
Examples
The following example shows how to set the MANET peering cost threshold to 3000.
Related Commands

|
---|---|
Usage Guidelines
Use the ospfv3 network manet command to enable relaying and caching of LSA updates and LSA ACKs on the MANET interface. This will result in a reduction of OSPF traffic and save radio bandwidth
By default, selective peering is disabled on MANET interfaces.
By default, the OSPFv3 dynamic cost timer is enabled for the MANET network type, as well as caching of LSAs and LSA ACKs received on the MANET interface. The following default values are applied for cache and timers:
Using this feature, you can configure broadcast networks as NBMA networks when, for example, routers in your network do not support multicast addressing. You can also configure non-broadcast multiaccess networks (such as X.25, Frame Relay, and Switched Multimegabit Data Service (SMDS)) as broadcast networks. This feature saves you from needing to configure neighbors.
Configuring NBMA networks as either broadcast or non-broadcast assumes that there are virtual circuits from every router to every router or fully meshed network. There are other configurations where this assumption is not true, for example, a partially meshed network. In these cases, you can configure the OSPF network type as a point-to-multipoint network. Routing between two routers that are not directly connected will go through the router that has virtual circuits to both routers. You need not configure neighbors when using this feature.
If this command is issued on an interface that does not allow it, this command will be ignored.
OSPF has two features related to point-to-multipoint networks. One feature applies to broadcast networks; the other feature applies to non-broadcast networks:

Usage Guidelines
You can specify multiple IP OSPFv3 routing processes in each router.The router ospfv3 command must be followed by the address-family command for routing of IPv6 traffic to occur.
Each OSPFv3 routing process must have a unique router ID. If a router ID is not configured manually (using the router-id A.B.C.D command), Cisco IOS attempts to auto-generate a router ID for this process from the IPv4 address of a configured interface. If Cisco IOS cannot generate a unique router-id, the OSPFv3 process remains inactive.
When you use the no form of the global router ospfv3 process-id command, the associated interface configuration ospfv3 process-id command is automatically removed from your configuration.

Command Modes
Command History
|
|
---|---|
Usage Guidelines
The Cisco 5921 ESR does not support this comand.
The network interfaces are shut down when declassification starts.
The output that appears on the console when declassification starts depends on which options have been configured. It is not possible to document exactly what appears on the screen, because of the complex interactions between the declassification process and the logging process during declassification.
You can use the trigger GPIO keyword after any of the other keywords for this command to start the declassification monitoring processing at the specified pin-number. By default the Cisco 5930 ESR starts the declassification monitoring process at GPIO pin 4.
Examples
The following examples show the console output when declassification is invoked.
The startup configuration file is also erased; the router boots from the factory default configuration the next time it is booted.
The output from the service declassify erase-all command resembles the following:
service declassify erase-flash
The startup configuration file is not erased if you enter the service declassify erase-flash command. When the Cisco 5930 ESR is booted, it uses the startup configuration file in NVRAM.
The output from the service declassify erase-flash command resembles the following:
service declassify erase-nvram
Note If you enter the service declassify erase-nvram command, the flash file system is not erased. The bootable image in the Flash file system remains and the Cisco 5930 ESR can be booted. The startup configuration file is erased; because the router has no configuration file, it boots from the default configuration.
The output fromthe service declassify erase-nvram command resembles the following:
service declassify erase-default
If you enter the service declassify erase-default command, neither the flash file system or NVRAM are erased. The declassification process quickly reaches a state in which the cisco IOS logging process is not operative and the common command output is not seen.
Even though this declassification process shutsdown interfaces, no messages display indication this.
The output fromthe service declassify erase-default command resembles the following:

shutdown
To deactivate an IP multiplexing profile, enter the shutdown command. To activate an IP multiplexing profile, use the no form of the command.
Command Modes
IP multiplexing configuration (config-ipmux-profile)
IPv6 multiplexing configuration (config-ipmux-profile-v6)
Command History
|
|
---|---|
Usage Guidelines
You must enter the no shutdown command to activate an IP multiplexing profile so that the IP multiplexing packet handler processes packets for IP multiplexing. A disabled multiplexing profile cannot send superframes, but will accept incoming superframes which match its configured source and destination addresses.
If you want to change the ACL associated with the profile, or edit the ACL associated with the profile, you must enter the shutdown command. After you have changed either the access-list or the ACL associated with the profile, you then enter the no shutdown command to clear the IP multiplexing cache and use the new information.
A multiplexing profile must have both a source and destination address configured in order to be activated.
Examples
The following example shows how to activate the IP multiplexing profile routeRTP-SJ.
singlepacket
Interesting data packets are always transmitted inside a superframe, even if there is only one packet to transmit when the hold timer expires. If you want the IP multiplexing packet handler not to create single packet superframes, enter the no singlepacket command. If you want to send single packet superframes, enter the singlepacket command.
Command Modes
IP multiplexing configuration (config-ipmux-profile)
IPv6 multiplexing configuration (config-ipmux-profile-v6)
Command History
|
|
---|---|
Usage Guidelines
By default the IP multiplexing packet handler creates single packet superframes.
Single packet multiplexing applies to all hold queues for a given IP multiplexing profile.
Examples
The following example shows how to configure single packet superframes for IP multiplexing profile routeRTP-SJ.
source
To specify the IPv4 or IPv6 source address for the local endpoint of the IP multiplexing path, enter the source command. To clear the source address, use the no form of the command.
source {ip_addr | ipv6_addr | interface interface_type}
Syntax Description
Command Modes
IP multiplexing configuration (config-ipmux-profile)
IPv6 multiplexing configuration (config-ipmux-profile-v6)
Command History
|
|
---|---|
Usage Guidelines
You must configure a source address for the profile in order to use it. If you attempt to issue a no shutdown command when no source address is configured, you will be prompted to configure a source address. If a profile is active, you must issue a shutdown command before changing the source address.
If you enter the source command again, then the new address overwrites the previously entered address.
An incoming superframe must match its source and destination addresses to the destination and source addresses, respectively, in the multiplexing profile in order for the superframe to be demultiplexed. If either address does not match, the superframe is ignored.
Examples
The following example shows how to configure the IPv6 address FE80::A8BB:CCFF:FE01:5700 as the source address for superframe packets.
summary-prefix (OSPFv3)
To configure an IPv6 summary prefix, use the summary-prefix command in router address-family configuration mode. To restore the default, use the no form of this command.
summary-prefix prefix [ not-advertise | tag tag-value ]
no summary-prefix prefix [ not-advertise | tag tag-value ]
Syntax Description
Command Default
Command Modes
Router address family configuration (config-rtr-af)
Command History
Usage Guidelines
The summary-prefix command can be used to summarize routers redistributed from other routing protocols. Multiple groups of addresses can be summarized. The metric used to advertise the summary is the smallest metric of all the more specific routes. This command helps reduce the size of the routing table.
Examples
In the following example, the summary prefix FEC0::/24 includes addresses FEC0::/1 through FEC0::/24. Only the address FEC0::/24 is advertised in an external LSA.
timers manet
To configure MANET timer parameters, use the timers manet command in router-configuration mode. To restore the timer default values, use the no form of this command.
timers manet { ackwait ackwait-value | peering peering-value | pushback pushback-value }
no timers manet { ackwait ackwait-value | peering peering-value | pushback pushback-value }
Syntax Description
Command Modes
Router configuration (config-rtr)
Command History
|
|
---|---|
Usage Guidelines
Non-active relays do not immediately start helping with flooding. Timers can be configured to delay Non-active relays until the active relay finishes its procedure. The timers manet command is used to configure these timers.
Peering Timers on MANET Interfaces
When selective peering is enabled, this timer determines how long the OSPFv3 process waits between selective peering decisions. Use the peering keyword to specify how long the router waits between selective peering decisions.
Acknowledgements on MANET Interfaces
When sending acknowledgments on a MANET interface, a small delay is configured in order to accumulate as many acknowledgments as possible into a single ACK message to reduce the number of messages being sent. Use the ackwait ackwait-value keyword and argument to set the acknowledgment wait timer.
Pushback Timers on MANET Interfaces
Use the pushback keyword to help prevent multiple non-primary relays from flooding at the same time. If a relay has already seen all of the acknowledgements from the nodes for which it is going to relay, it will cancel the pushback timer.
The default value for the pushback timer is 50 percent of the retransmit timer value.
Examples
The following example shows how to set the MANET pushback timer to 50,000 milliseconds, the MANET acknowledgement timer to 1001 milliseconds, and the MANET peering timer to 1000 seconds:

|
---|---|
This command was integrated into Cisco IOS Release 12.2(28)SB. |
|
This command was integrated into Cisco IOS Release 12.4(24)GC. |
Usage Guidelines
The first wait interval between SPF calculations is the amount of time in milliseconds specified by the delay argument.
Use the next-delay argument to set the delay between the first and second SPF calculations.
Each consecutive wait interval is two times the current hold level in milliseconds until the wait time reaches the maximum time in milliseconds as specified by the holdtime argument. Subsequent wait times remain at the maximum until the values are reset or an LSA is received between SPF calculations.
When you configure an OSPFv3 network manet for any interface attached to the OSPFv3 process, the default values for the delay, next-delay, and hold time are reduced to 1000 milliseconds, 1000 milliseconds, and 2000 milliseconds respectively.
Examples
The following example shows a router with the delay and next-delay interval values configured at 40 milliseconds, and the holdtime value to 50 milliseconds :
