Extending Vlans

[adunn]

I have just purchased 3 x Avaya Routing switches 3524GT+. I am using them on an Avaya IP Office to connect computers and telephones. I have setup the 1st switch to allow a telephone to be connected and the computer connecting via the telephone. This works fine but I now need to deploy the other switches in different Communications Cabinets in different locations. I have the same two Vlans on the other switches but I don't get any DHCP from the IP Office across these other switches. I am not sure how to create the links to these switches.

Any assistance would be great.

If the aim is to extend the same Data & Voice VLAN across mutiple switches, then first onfigure the same VLAN IDs on the other switches. Then on the links which you use to join the switches together set the port on both end of the link to VLAN Tagging enabled. Then set those ports for the links to have all the VLANs on those ports and the switches will trunk multiple VLANs across those connections.

also, don't enable DHCP Snooping for now, DHCP Snooping is very usefull because it can block DHCP Request coming from a Rogue DHCP server. But in your case, it will not help you if it is miss configured.
