Re: Where are VLANs defined?
my advice
you can create manually every switch on every vlan
but if you want
create dynamic vlan learning on 2650 switch with GVRP protocol
GVRP protocol running only vlan aware ethernet card or 802.1x configuration
please send me all switch show run commad print I make vlan config for you

Re: Where are VLANs defined?
Am I right in thinking I create each VLAN the same way on every switch, including the VLAN IP address? So:
all switches have VLAN ID 2 192.168.1.1/24 for example, with untagged ports for hosts and tagged (dynamic) uplink ports connected to the 5400s (which have IP Routing enabled)?
Thanks again,
Simon

SolutionYou definitely don't want to use the same IP address on multiple devices, duplicate IP addresses will cause you all sorts of grief.
For the 2650's, they just need one unique IP address in your management VLAN. I usually use VLAN 1 for that purpose.

Re: Where are VLANs defined?
vlan ip address must be serried
for example
switch 1 vlan 1 ip address 192.168.1.1/24
switch 2 vlan 1 ip address 192.168.1.2/24
switch 3 vlan 1 ip address 192.168.1.3/24
untagged port for host
tagged port for uplink port
but you can create vlan config two switch each uplink port must be
vlan 1 untag port all other vlan tag port
if you want communications between vlan
you can enable ip routing

Re: Where are VLANs defined?
Just to clarify:
As we currently don't have the VRRP license for our 5400s, we need to nominate one 5400 as the "router" and initially create the VLANs (with IP addresses assigned) there. Then create the VLANs (without any IP addr assigned) on every 2650 and then assign ports to the appropriate VLAN (untagged). The 2650's gig 49 & 50 ports will be untagged members of the default VLAN (1) and tagged in all other VLANs to enable traffic to be routed.
All switches have IP addresses in the default VLAN (this is already the case).
I'll look into getting the premium edge license as we also have 2 other comms cabs with 2 3500s and 8 2650s in each connected to the main cab by 10 gig fibre. The network was built before I joined but was left as a flat /8. STP is enabled on all switches but we have a big problem with slow down, possible due to large amounts of broadcast traffic...
