Usage:
This command enables
or disables revertive port redundancy, wherein after a port failover, when
the original port is restored to service (such as link up) the system
will return service to that port automatically.
Disabled, which is
the default setting, causes non-revertive operation; requiring an administrative
user to manually issue a port switch to command to return service
to the original port.
This command must
be issued on a per port basis, allowing you to configure specific
ports to be used on individual line cards or SPIO cards. For example,
ports 1 through 4 could be configured as “preferred” on
the line card in slot 17, while ports 5 through 8 are “preferred” on the
line card in slot 33. In this scenario, both line cards would be
in an Active operational state while still providing LC and port
redundancy for the other.
IMPORTANT:
This command is not
supported on all platforms.
