I have three switches daisy-chained together and I have a printer vlan serviced with a print server off the core (1st) switch. the middle switch trunk port will not accept the printer vlan. I issue the following command "switchport trunk allowed vlan all" which should add all vlans to the trunk. HOwever, when I run the "show interface trunk" command the printer vlan is missing from the "Vlans in forwarding state and not prunned" list. My switch is in vtp client mode and has a default route that is pingable. Any assistance would be greatly appreciated. All switches are 3750s (12.52 IOS) except the core which is a 6509.

Does the printer vlan show up on the middle switch if you run "sh vlan"? – pauska Jul 27 '11 at 11:35

Post the output of: sh vlan, sh vlan id $PRINTERVLAN and sh int $TRUNK switchport. – MikeyB Jul 27 '11 at 21:03
