Usage Information Example The no version of this command disables L3 routing. OS10(conf-vlt-1)# peer-routing Supported Releases 10.2.0E or later peer-routing-timeout Configures the delay after which peer routing is disabled when the peer is not available. This command is applicable for both IPv6 and IPv4. Syntax peer-routing-timeout value Parameters value - Enter the timeout value in seconds, from 0 to 65535. Default 0 Command Mode VLT-DOMAIN Usage Information Use this command to configure a timer to disable the peer-routing when the peer is not available. When the timer expires, the software checks to see if the VLT peer is available. If the VLT peer is not available, peer-routing is disabled on the peer. If you do not configure the timer, peer-routing is not disabled even when the peer is unavailable. Example OS10(conf-vlt-1)# peer-routing-timeout 120 Supported Releases 10.3.0E or later primary-priority Configures the priority to be used for selecting the primary and secondary VLT peers during election. Syntax Parameters Default Command Mode Usage Information primary-priority value value - To configure the primary role on a VLT peer, enter a lower value than the priority value of the remote peer. The range is from 1 to 65535. The default value is 32768. 32768. VLT-DOMAIN • After you configure a VLT domain on each peer switch and connect (cable) the two VLT peers on each side of the VLT interconnect, the system elects a primary and secondary VLT peer device. To configure the primary and secondary roles before the election process, use the primary-priority command. Enter a lower value on the primary peer and a higher value on the secondary peer. If the primary peer fails, the secondary peer (with the higher priority) takes the primary role. If the primary peer (with the lower priority) later comes back online, it is assigned the secondary role (there is no preemption). • If the priority values configured on the two VLT peers are equal, VLT uses the default primary election mechanism based on the values of the system MAC addresses of the two nodes. The VLT peer with the lowest system MAC address assumes the primary role. • In a scenario where the heartbeat is up and the VLTi link goes down between the VLT peers, both the VLT peers retain their primary and secondary roles. However, the VLT LAG on the secondary VLT peer is shutdown. NOTE: When you configure priority for VLT peers using this command, the configuration is not effective immediately. This primary priority configuration comes into effect the next time election is triggered. Virtual Link Trunking 733

Usage Information

The

version of this command disables L3 routing.

Example

OS10(conf-vlt-1)# peer-routing

Supported Releases

10.2.0E or later

peer-routing-timeout

Conﬁgures

the delay after which peer routing is disabled when the peer is not available. This command is applicable for both IPv6 and IPv4.

Syntax

peer-routing-timeout

value

Parameters

value

— Enter the timeout value in seconds, from 0 to 65535.

Default

Command Mode

VLT-DOMAIN

Usage Information

Use this command to

conﬁgure

a timer to disable the peer-routing when the peer is not available. When the timer

expires, the software checks to see if the VLT peer is available. If the VLT peer is not available, peer-routing is

disabled on the peer. If you do not

conﬁgure

the timer, peer-routing is not disabled even when the peer is

unavailable.

Example

OS10(conf-vlt-1)# peer-routing-timeout 120

Supported Releases

10.3.0E or later

primary-priority

Conﬁgures

the priority to be used for selecting the primary and secondary VLT peers during election.

Syntax

primary-priority

value

Parameters

value

— To

conﬁgure

the primary role on a VLT peer, enter a lower value than the priority value of the remote

peer. The range is from 1 to 65535. The default value is 32768.

Default

32768.

Command Mode

VLT-DOMAIN

Usage Information

•

After you

conﬁgure

a VLT domain on each peer switch and connect (cable) the two VLT peers on each side of

the VLT interconnect, the system elects a primary and secondary VLT peer device. To

conﬁgure

the primary

and secondary roles before the election process, use the

primary-priority

command. Enter a lower value

on the primary peer and a higher value on the secondary peer. If the primary peer fails, the secondary peer

(with the higher priority) takes the primary role. If the primary peer (with the lower priority) later comes back

online, it is assigned the secondary role (there is no preemption).

•

If the priority values

conﬁgured

on the two VLT peers are equal, VLT uses the default primary election

mechanism based on the values of the system MAC addresses of the two nodes. The VLT peer with the lowest

system MAC address assumes the primary role.

•

In a scenario where the heartbeat is up and the VLTi link goes down between the VLT peers, both the VLT

peers retain their primary and secondary roles. However, the VLT LAG on the secondary VLT peer is shutdown.

NOTE:

When you

conﬁgure

priority for VLT peers using this command, the

conﬁguration

is not

eﬀective

immediately. This primary priority

conﬁguration

comes into

eﬀect

the next time election is triggered.
