Enterasys Networks VH-8G manual Configuring Port Trunks

Configuring Port Trunks

You can configure up to four port trunks on the VH-8G switch. Each trunk can combine up to four ports into an aggregate connection with up to 8Gbps of bandwidth when operating at full duplex. Besides balancing the load across each port in the trunk, the additional ports provide redundancy by taking over the load if another port in the trunk should fail.

To configure the port trunks, do the following:

1.Select the Device Control Menu from the Main Menu.

2.Select Port Trunking Configuration.

3.Enter a Trunk ID number from 1 to 4 to identify the trunk.

4.Select up to four ports to configure as one trunk. You can configure up to four trunks per switch unit.

Note that ports at both ends of a trunk must be configured in an identical manner, including duplex mode and VLAN assignments.

5.For each Trunk ID, select Enable to enable the trunk.

Note that it is advisable to enable the trunk prior to connecting any cable between the switches to avoid creating a loop.

When using port trunks, remember that:

•Before removing a port trunk via the configuration menu, you must disable all the ports in the trunk or remove all the network cables. Otherwise, a loop may be created.

•To disable a single link within a port trunk, you should first remove the network cable, and then disable both ends of the link via the configuration menu. This allows the traffic passing across that link to be automatically distributed to the other links in the trunk, without losing any significant amount of traffic.
