Hi Guys,
The following config was applied to 3750 switch ports and appeared to have a detrimental effect on the LAN. It seems that the config put all user traffic into native Vlans, which then left the traffic floating around in the core with nowhere to go. Ooops - not clever!! Each floor has it's own Vlan and voice is the same for all floors.
The STP, queueing and mls entries are the defaults created by the "auto qos voip trust" cmd
description *** Phones or PC's ***
switchport trunk encapsulation dot1q
switchport trunk native vlan 110
switchport trunk allowed vlan 300,110
switchport mode trunk
switchport voice vlan 300
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
mls qos trust cos
auto qos voip trust
spanning-tree portfast
spanning-tree bpduguard enable
Currently the phones have not been deployed, therefore only host PC's are in use, so when the config was ripped out and replaced with just access port commands all settled down and the LAN runs sweetly.
So the question is, and it's a bit of a grey area for me, what should the port config look like in order to support the Nortel phones when they are rolled out? They don't support CDP as the new Mitel SW version does so Im a bit stuck and would appreciate some input.
Regards
Ali
