I'm trying to depreciate usage of VLAN 1 on my ProCurve switches; 1 is unused. I understand that VLAN 1 must exist, but I want to remove it from all ports, especially trunks between switches.

The problem I have is that stacking does not seem to work without VLAN 1.

I have changed the primary VLAN and management VLAN on all the switches:

(config)# primary-vlan 42
(config)# management-vlan 42
(config)# no vlan 1 untagged 25

Port 25 is the link between the 2 switches I'm testing with; the stack master and a member switch; I only want tagged traffic between the switches, no untagged frames.

show stacking on the master shows all members as "UP" but I can not telnet any of them:

Telnet failed: Connection timed out.

All switches have manually assigned (static) IP addresses on VLAN 42, and all exist in the same /25 subnet, as does my desktop. I can telnet the switches directly from my desktop to the individual switch IP addresses, just not from the master switch.

Do I need to reboot the switches to have the primary-vlan change take effect? Or is there something else I'm missing?

EDIT: show vlans output:

Which HP ProCurve switch model(s) are you using? –  ewwhite Dec 17 '12 at 3:51
Sorry, I did forget that. The stack master is a 2510G-48, the member I'm testing with is a 2510-24. The other members in the stack are 2510G-24, 2510-48 and 2520-8-PoE. All show the same behaviour, and all are running latest available firmware. –  fukawi2 Dec 17 '12 at 4:13
I'm just a bit rusty on procurve but try to mark the primary vlan as untagged. –  eldblz Dec 17 '12 at 7:31
Can you also provide a exibit of command "show vlans" please? –  eldblz Dec 17 '12 at 7:41
When setting up our 5400zl's we had to set one vlan as untagged and tag everything else. It just wouldn't work with all set to tagged. –  kormoc Jan 29 '13 at 0:36
