We have several old Cisco switches (currently only have VLAN 1 for everything). We are moving to a VOIP setup with Brocade and so I've (hopefully) configured the Brocade switch to handle the traffic correctly.
I've configured the Brocade with a default VLAN ID of 1, VLAN 10 for data/LAN traffic, VLAN 20 for our guest WIFI network, and VLAN 30 for VOIP. The phones should tag the packets for VLAN 30, the PC data should be untagged but come in as VLAN 10.
My question is: How can I get the old Cisco switch to take the VLAN 10 traffic and put it on it's default VLAN so that I don't have to create a VLAN 10 on two dozen Cisco switches that will be replaced soon anyway?
