MC-LAG Commands
mc-lag
Syntax [no] mc-lag
Context config>redundancy>multi-chassis>peer>mc-lag
Description This command enables the context to configure multi-chassis LAG operations and related parameters.
The no form of this command administratively disables multi-chassis LAG. MC-LAG can only be issued
only when mc-lag is shutdown.
hold-on-neighbor-failure
Syntax hold-on-neighbor-failure multiplier
no hold-on-neighbor-failure
Context config>redundancy>multi-chassis>peer>mc-lag
Description
This command specifies the interval that the standby node will wait for packets from the active node before
assuming a redundant-neighbor node failure. This delay in switch-over operation is required to
accommodate different factors influencing node failure detection rate, such as IGP convergence, or HA
switch-over times and to prevent the standby node to take action prematurely.
The no form of this command sets this parameter to default value.
Default
3
Parameters multiplier — The time interval that the standby node will wait for packets from the active node before
assuming a redundant-neighbor node failure.
Values
keep-alive-interval
Syntax keep-alive-interval interval
no keep-alive-interval
Context config>redundancy>multi-chassis>peer>mc-lag
Description
This command sets the interval at which keep-alive messages are exchanged between two systems
participating in MC-LAG. These keep-alive messages are used to determine remote-node failure and the
interval is set in deci-seconds.
The no form of this command sets the interval to default value
Default
1s (10 hundreds of milliseconds means interval value of 10)
