fault-propagation edit

fault-propagation edit - Modify port fault propagation options

Description:

When fault propagation is enabled for a port, its link status (up or down) depends on the opposite port status, EVC status or SA status. Fault propagation could be based on link status only, link status and EVC status, or SA status.

In link status only operation mode, a link down on the opposite port is propagated to the specified port. Link status fault propagation is allowed in both directions. It can be enabled on a port and its opposite port.

In EVC status operation mode, the status of PAA probe(s) and/or CFM MEP(s) are propagated to the specified port. At least one PAA probe or CFM MEP should be free of connectivity errors to enable the specified port.

If there is no PAA probe and no CFM MEP configured in EVC fault propagation mode for the specified port, that port will stay down. When enabled for a port, fault propagation should be disabled on the opposite port.

In SA status operation mode, the status of SA is propagated to the specified port. If there is no in-service SA whose Client Port Cut-Off feature state is enabled and the configured client port is same as the specified port, that port will stay down. When enabled for a port, that port cannot be configured as the source port of any fault propagation configuration.

Syntax:

fault-propagation edit <port-name> {
        {state <enable | disable> }
        {mode  <evc | link | sa-status> }
        {fp-port <fp-port-name> }}+

Parameters:

fault-propagation enable/disable

fault-propagation enable - Enable fault propagation for a port
fault-propagation disable - Disable fault propagation for a port

Description:

When fault propagation is enabled for a port, a link down on the opposite port will be propagated to that port.

These commands are deprecated and have been kept for backward
compatibility purpose. The command "fault-propagation edit" should be used instead.

Syntax:

fault-propagation {enable | disable} {<port-name>}

fault-propagation show

fault-propagation show - Show fault propagation configuration

Description:

Show fault propagation configuration.

Syntax:

fault-propagation show [<port-name>]
