Features You can configure these features for resilient links:
■
Define — Specify a name and the ports that you want to associate
with the link.
■
Link state
— Enable or disable a resilient link pair.
■
Active port — Define either port as the port that carries network
traffic.
■
Modify — Change the name and ports that are associated with a
previously defined resilient link.
■
Remove — Delete one or more resilient links from the module.
Benefits
■
Resilient links enable you to protect critical links and prevent network
downtime if those links fail.
■
3Com recommends that you implement resilient links in these
network configurations:
■
Switch-to-switch downlinks from the wiring closet to the data
center. The resilient link pair must terminate on a Layer 2
data-center switch.
■
Server-to-switch connections in the data center and campus
interconnect areas.
Key Concepts
■
When you define a resilient link pair, you define:
■
The main port — The port on which network traffic runs under
normal operation.
■
The standby port — The port to which network traffic shifts if
the main port fails.
■
You can define either the main port or the standby port as the active
port, that is, the port that is carrying network traffic. The main port is
usually defined as the active port.
