Chapter 23 Configuring Gigabit EtherChannel Features Configuring High Availability Support on GEC Bundle Configuring High Availability Support on GEC Bundle The following high availability features are supported on GEC bundle interfaces, on the Cisco 10000 Series router. • Stateful Switchover (SSO) • In Service Software Upgrade (ISSU)) • Nonstop Forwarding (NSF) • Nonstop Routing (NSR) The EtherChannel and the IEEE 802.3ad LACP protocol are SSO and ISSU aware. This feature makes the GEC bundle interface available after a PRE switchover, in the event of a catastrophic failure. For more information on NSF, see Cisco Nonstop Forwarding whitepaper at: http://www.cisco.com/en/US/docs/ios/12_2s/feature/guide/fsnsf20s.html For information on SSO see, Stateful Switchover feature guide at: http://www.cisco.com/en/us/docs/ios/12_2s/feature/guide/fssso20s.html For more information on ISSU, see Cisco IOS In Service Software Upgrade and Enhanced Fast Software Upgrade Process feature guide, at: http://www.cisco.com/en/US/docs/ios/12_2sb/feature/guide/sb_issu.html Configuring 8 Member Links per GEC Bundle A maximum of 8 configured member links per GEC bundle and 64 port channels are supported on the Cisco 10000 Series router. The number of member links per GEC bundle has been increased from 4 to 8 in the Cisco IOS Release 12.2(15)BX. Configuration Tasks The following table lists the configuration commands used to configure the maximum and minimum links on a GEC bundle on a Cisco 10000 Series router. Command router(config-if)# lacp max-bundle 1-8 router(config-if)# lacp min-link 1-8 router(config-if)# lacp fast-switchover Purpose Assigns the maximum number of links per bundle. The default value is 8. Sets the minimum number of active links required before declaring the port channel interface down. The default value is 1. Reduces the switchover time from 2 seconds to 10ms. By default lacp fast-switchover configuration is not enabled. For more information on configuring member links, see the Link Aggregation Control Protocol (LACP) (802.3ad) for Gigabit Interfaces feature guide at: http://www.cisco.com/univercd/cc/td/doc/product/software/ios122sb/newft/122sb31/10gigeth.htm OL-2226-23 Cisco 10000 Series Router Software Configuration Guide 23-11

Configuring Gigabit EtherChannel Features
Configuring High Availability Support on GEC Bundle
Configuring High Availability Support on GEC Bundle
The following high availability features are supported on GEC bundle interfaces, on the Cisco 10000
Series router.
Stateful Switchover (SSO)
In Service Software Upgrade (ISSU))
Nonstop Forwarding (NSF)
Nonstop Routing (NSR)
The EtherChannel and the IEEE 802.3ad LACP protocol are SSO and ISSU aware. This feature makes
the GEC bundle interface available after a PRE switchover, in the event of a catastrophic failure.
For more information on NSF, see
Cisco Nonstop Forwarding
whitepaper at:
For information on SSO see,
Stateful Switchover
feature guide at:
For more information on ISSU, see
Cisco IOS In Service Software Upgrade and Enhanced Fast Software
Upgrade Process
feature guide, at:
Configuring 8 Member Links per GEC Bundle
A maximum of 8 configured member links per GEC bundle and 64 port channels are supported on the
Cisco 10000 Series router. The number of member links per GEC bundle has been increased from 4 to
8 in the Cisco IOS Release 12.2(15)BX.
Configuration Tasks
The following table lists the configuration commands used to configure the maximum and minimum
links on a GEC bundle on a Cisco 10000 Series router.
For more information on configuring member links, see the
Link Aggregation Control Protocol (LACP)
(802.3ad) for Gigabit Interfaces
feature guide at:
Command
Purpose
router(config-if)#
lacp max-bundle
1–8
Assigns the maximum number of links per bundle.
The default value is 8.
router(config-if)#
lacp min-link
1–8
Sets the minimum number of active links required
before declaring the port channel interface down.
The default value is 1.
router(config-if)#
lacp fast-switchover
Reduces the switchover time from 2 seconds to
10ms. By default lacp fast-switchover
configuration is not enabled.
