I am confusing with private vlan now,
1. PVLAN can only work under vtp transparent mode, how can I set up the trunk with other switches then? (I was curious the transparant mode on 2960 works another 2960 in clinet mode)
2. How does PVLAN work with L2 Switch? or can't?
3. It says PVLAN could save the vlan id. but we still need to create vlan and associate it to prime VLAN. How does it save the VLAN ID?
For example, I have one 3560 and two 2960, currently I set 3560 as vtp server and configure g1/47 and g/48 as trunk mode for each 2960(g0/1). VLAN 10, 20, 30 have been configured on 3560 and assigned to the ports on 3560 and 2960.
Is there any configuration for reference? Can anyone help me to sort out these? Thank you.
Because VTP does not support PVLANS so you must create the PVLAN on each switch.
You can implement it on a switch but you are right in what you say, if the switch is getting constantly updated it requires a fair bit more work if the switch is in VTP transparent mode.
