Port Trunking is a feature that allows multiple links between switches to work as one virtual link
(aggregate link). Trunks can be defined for similar port types only. For example, a 10/100 port
cannot form a Port Trunk with a gigabit port. For 10/100 ports, trunks can only be formed within
the same bank. A bank is a group of 8 10/100 ports or 2 gigabit ports, for example, ports 1 to 8,
ports 9 to 16, ports 17 to 24, or port 25 and port 26, on the same switch unit. Up to four trunks can
be enabled at the same time. To set up a trunk, click on the ports that will participate in the trunk.
Spanning Tree will treat trunked ports as a single virtual port.
Note: You must use straight-though cables for all links in the trunk. Do not use crossover cables.
Also, you must disable auto-negotiation on the ports in a trunk prior to setting up the trunk.
Advanced > Virtual Cable Tester
The virtual cable tester feature lets you test the continuity of the GBIOC cable circuit.
Figure 5-27: Virtual Cable Tester
The results are reported for the selected port. The test can take up to one minute.
Note: Only the console menu will let you run the virtual cable tester on any port. Other
management interfaces require port access and therefore cannot reliably test the cable continuity of
the port they are using to access the switch.
