Use this command to enable Link Failure Response (LFR) on the physical chassis.
| enable | disable | Enables or disables LFR on the physical chassis. Default value is disable. |
LFR is globally Disabled.
All command modes.
This command provides for enabling and disabling the LFR protocol on the physical chassis.
The LFR protocol determines which chassis front-panel ports will be brought down should all VSB interconnect links between the VSB chassis go down.
The LFR protocol allows 1 or 10GbE ports to be designated as VSB monitor links that operate in a standby mode to the primary 40GbE VSB ports. The VSB monitor link provides dedicated redundant control plane connectivity and is used only as a backup communication path between two bonded chassis in the unlikely event that all of the primary VSB links fail or become unavailable. When the primary 40GbE VSB ports are down, the VSB monitor links facilitate a communications path to allow the front-panel ports of the stack segment that meets a minimum requirement as specified in 7100-Series Virtual Switch Bonding (VSB) Stacking Configuration in the S-, K-, and 7100 Series Configuration Guide to remain enabled.
The LFR protocol must be enabled on each VSB chassis in the VSB system for LFR monitoring to occur.
This example enables the LFR protocol on the VSB chassis:
System(rw)->set bonding lfr enable
