Hi,
I was under the impression that dot1q trunking is dot1q trunking . Have
a integration situation where core access layer devices that uplink to
core of the network are foundry layer 2/3 switches. Now some cisco 3550
switches need to hang off of these foundry switches in each of the idf
closets. Cisco phones will be plugging into the foundry switches and
cisco switches , cisco supports the aux/voice vlan feature so that
devices using the Ethernet port on the back of the cisco IP phones can
be on a different vlan/ip subnet than the phone / voice itself. When
setting up foundry trunking via 802.1q into the cisco network , there
seems to be now way to match the voice and data vlans , so the only way
to put phones on the back of the foundry switch is with pc and phone on
same vlan , has anyone else played with foundry and cisco 802.1q
trunking
TIA , Long
