Setting up a CrossLink
To add a CrossLink between two switches, determine which Token-Ring ports to
use for the CrossLink. Use at least 2 Token-Ring ports.
The switch treats the port with the lowest number as the primary port. For example,
if a CrossLink consists of ports 8, 11, and 13, the primary port is 8. Broadcast,
multicast, and unknown destination packets are forwarded to the primary port in a
CrossLink. The primary ports of both CrossLinks must be connected to each other.
For example, if a CrossLink links ports 8, 11, and 13 of one device and ports 3, 6,
and 9 of another device, ports 8 and 3 must be connected to each other.
Observe the following precautions and use the following steps to set up a
CrossLink:
•
Disable or disconnect the Token-Ring ports before creating or changing a
CrossLink.
•
You must define the CrossLink for both connected switches before physically
connecting their linked ports. Do not connect the cables before configuring the
switches; if you do, you may create loops.
•
Cable only the Token-Ring ports you have added to the CrossLink menu. If
you connect additional ports between two switches, a loop results.
1. Disconnect the Token-Ring ports you want to add to the CrossLink, or disable
them using the Port Configuration menu.
2. For each switch, select the CrossLink Configuration menu, then choose Add
Entry from the menu bar at the bottom of the screen.
3. Enter the Token-Ring ports for the first CrossLink, separated by spaces.
4. Choose Return. (A reset is not required).
5. Repeat steps 1 through 4 for the other switches.
6. Set the Address Aging Time to the same value for the switch devices.
7. If you disconnected the Token-Ring ports in the CrossLink, reconnect them. If
you disabled them using the Port Configuration menu, use the menu to re-
enable them.
