Cisco VTP functionality

[horiz0n]

Hi,

I am trying to configure three J9851A with something like VTP (GVRP in HP), but it looks to be a slightly different and something is wrong with my configuration.

I have:

connected linux based router into A1 port with three vlans (default, vlan2, vlan3) marked as tagged.

connected test desktops into F1, F2 on first switch (both marked as untagged). F1 is in vlan2 and F2 is in vlan3. it is working as expected, there is no communication between vlans and there is communication with linux router.

now I would like provide trunk to another J9851A and automagically create/inherit the same vlans on it (without adding ports).

how can I do this?

"Show VLAN" should now show some dynamic VLANs (generated because GVRP detected new VLANs coming in). Another switch with L2 connectivity (eg default untagged VLAN 1 ports) connected together with GVRP running should see those VLANs propagate to it.

Check with "show VLAN", "show vlan port A1 detail"

switch05# sh vlans

you can convert dynamic to static with "static-vlan 2"
