Resilient Link State 239
■
If you have already defined other resilient links on your module, you
cannot select ports that are part of an existing resilient link to be part
of an additional resilient link pair.
■
You cannot select a trunked port nor the trunk itself as part of a
resilient link.
■
The resilient link name can be up to 32 characters long.
See the
Switch 4007 Command Reference Guide
for a complete
description of the resilient link commands.
Resilient Link State
You can enable or disable one or more resilient link pairs with a single
command.
Important
Considerations
■
When the link state is enabled , the resilient link can transmit and
receive traffic.
■
When the link state is disabled , the resilient link no longer transmits or
receives frames.
Resilient Link
Active Port
The active port is the port that carries traffic. You can designate either the
main port or the standby port as the active port.
Important
Considerations
■
Only one port in a resilient link pair is active at a time.
■
By default, the module defines the main port in a resilient pair as the
active port when you reboot, unless the main link is down.
■
If the main link is of equal or lesser bandwidth than the active standby
link, the switchover back to main link is not automatic. If you want the
main link to be active, you must configure it as the active port.
Resilient
Link Remove
You can remove one or more resilient links with a single remove
command.
Important
Consideration
■
After you remove a resilient link pair, you must reboot the module.
