6.4 Troubleshooting
Problem One
I don’t need VLANs at all. How do I turn them off?
Simply leave all ports set to type “Edge” and leave the native VLAN set to 1. This is the default
configuration for the switch.
Problem Two
I have added two VLANs 2 and 3. I made a number of ports members of these VLANS.
Now I need some of the devices in one VLAN send messages to some devices in the
other VLAN.
If the devices need to communicate at the physical address layer, they must be members of the
same VLAN. If they can communicate in a layer 3 fashion (i.e. using a protocol such as IP or
IPX) you can use a router. The router will treat each VLAN as a separate interface, which will
have its own associated IP address space.
Problem Three
I have a network of thirty switches for which I wish to restrict management traffic to a
separate domain. What is the best way of doing this while still staying in contact with
these switches?
At the switch where the management station is located, configure a port to use the new
management VLAN as its native VLAN. Configure a host computer to act as a temporary
management station.
At each switch, configure the management VLAN to the new value. As each switch is configured
you will immediately lose contact with it, but should be able to re-establish communications from
the temporary management station. After all switches have been taken to the new management
VLAN, configure the ports of all attached management devices to use the new VLAN.
Note: Establishing a management domain is often accompanied with the establishment of an IP subnet
specifically for the managed devices.
