T22P VLAN not working - asmith3006 - 08-04-2014 08:11 PM Hi, I'm having issues getting my T22P phone to switch VLANs based on the DHCP tag 132. I am using Windows DHCP server I have created two scopes (172.23.70.1 = VLAN 70 and 172.23.19.1 = VLAN 19) I have specified the DHCP tag 132 with a value of "19" (no quotes) I have set the switch port to be default VLAN 70 and tagged for 19 I boot the phone, it gets the VLAN 70 DHCP address but doesn't switch VLANs If I boot the phone and log into the web interface and manually specify the VLAN as 19 then it boots into the correct VLAN and gets a valid DHCP address, so I am sure the tagging on the switch ports is correct and the DHCP scope is working (and DHCP helpers are correct etc.). I am using firmware 7.71.0.224 Does anyone have any suggestions as to what I can try to resolve this? Thanks and regards Andrew. RE: T22P VLAN not working - asmith3006 - 08-06-2014 07:02 PM I'm beginning to think this is a conflict between LLDP and the DHCP tag. If I disable LLDP on my test rig (Juniper EX4200) then this works, but with LLDP enabled it does not. Is this the right behaviour? I don't have any LLDP policies configured.
