Resilient Link Rules
Always follow these rules when setting up a resilient link pair:
■
Only 10BASE-T and fiber optic ports (if the hub has a fiber optic
transceiver module fitted) can be part of a resilient link.
■
Configure the resilient link pair at only one end of the link. In other
words, only one stack controls each resilient link pair you set up.
■
Each resilient link pair can only have one main link and one standby
link (the ports used can be on different hubs in the stack).
■
Each link must not belong to more than one resilient link pair.
■
For a port that is part of a resilient link pair:
■
Do not disable the link pulse generation (you cannot disable this
using the web interface or Quick Config manager).
■
Do not enable security for the port.
If you have more than two stacks there are a number of ways you can
use resilience when linking them. Remember to connect the stacks
correctly for both links, refer to “Connecting Different Hubs and Stacks
to Your Hub” on
page 3-16
.
If the main link fails, the standby link becomes active.
Adding, Deleting and Swapping Links
To add a resilient link pair to the list, click
Add
. The Add Resilient Link
page is displayed.
To delete a resilient link pair from the list, click on the entry in the list
and then click
Delete
. The resilient link pair is deleted, and the current
active link remains enabled and the standby link is cancelled.
To swap the main and standby ports for a resilient link pair in the list,
