Cabletron Systems 802.1Q manual Use the Port Assignment Configuration screen for the following

Managing the Switch

b.Set the FID so the Management VLAN has its own number to make the VLAN secure. In this example, the FID is 3 and no other VLAN should be assigned to this FID. This keeps the new VLAN from sharing its filtering database with other VLANs in the switch. For details on defining a VLAN, refer to Section 3.4.1.

2.Use the Port Assignment Configuration screen for the following:

a.Assign the VLAN ID, 2, of the new Management VLAN to a port. In this example, it is port 1. Leave the Port Mode setting in the default value of HYBRID.

NOTE

It is not necessary to configure a physical port for management on each switch. Only those switches that will have a management station attached to it need a physical port assigned to the Management VLAN.

b.Assign the VLAN ID, 2, of the new Management VLAN to the Host Data Port. The port number will depend on the device. This port is not a physical port and will usually be one number above the maximum number physical ports on the device, including the ports on any optional interfaces installed. In this example, it will be port 8. Leave the Port Mode setting in the default value of HYBRID. For details on assigning a VLAN ID, refer to Section 3.4.2.

This process would be repeated on every switch that is connected in the network to ensure that each switch has a secure Management VLAN for switch management.

If the switch was connected to another switch via port 7, which was set as a 1Q Trunk port, then the management station connected to the Management VLAN port of either switch could manage both switches.

NOTE

The management stations at each switch must be on the same Management VLAN.

No matter how many switches are connected, a management station connected to any port on the same Management VLAN can be used to remotely manage any Cabletron Systems 802.1Q switch in the network as long as the Host Data Port of all the switches are members of the same Management VLAN.
