Setting Up Resilient Links
You can protect a critical communication link against
failure by ensuring that, should the main communication
link fail, a standby duplicate communication link
immediately and automatically takes over the task of
the main link.
Each main and standby link pair is referred to as a
resilient link pair
.
■
If you wish to setup an ATM port as part of a
resilient link, the other port in the resilient link
must be a
Virtual LAN Trunk
(a member of all
VLANs).
■
Typically the ATM Module port is paired with a Fast
Ethernet port on the ATM Switch.
