■
Resilient link pairs can only be set up using fiber or twisted pair ports.
The main and standby ports in the same pair, however, can use any
combination of these media.
■
A resilient link pair must only be defined at one end of the link.
■
A resilient link pair must only be set up if:
■
The ports belong to the same VLANs.
■
The ports use the same VLAN tagging system (802.1Q tagging or
VLT tagging).
■
The ports have the same IEEE 802.1Q VLAN learning setting.
■
The ports have the same IEEE 802.1p multicast learning setting.
■
Neither of the ports are secure ports (have security enabled).
■
Neither of the ports are part of a port trunk.
■
Neither of the ports belong to another resilient link pair.
■
The port state of ports in a resilient link pair cannot be changed unless
a link failure occurs.
Displaying Resilient Link Pairs
The Resilient Links page displays the resilient link pairs that are set up for
the stack:
■
Main Link
Unit 1 Port 1 / Unit 1 Port 2 / ...
Displays the port in the stack that is the main port of the resilient link
pair, and the state of the link on that port.
■
Standby Link
Unit 1 Port 1 / Unit 1 Port 2 / ...
Displays the port in the stack that is the standby port of the resilient
link pair, and the state of the link on that port.
■
Pair State
Operational / Not Operational
Displays whether the resilient link pair is operational or not. When the
pair is operational, either the main port or the standby port can
forward traffic.
Creating a Resilient Link Pair
The Resilient Links page allows you to create a resilient link pair. To do
this:
1
Click the
Add...
button. The first Add Resilient Links page is displayed.
2
Select the Switch units that are to contain the main port and standby port
of the resilient link pair.
