Hello,
My VOIP phones are not working properly when connected to the second switch.
Here's an idea of my config :
Switches are ESW540-24P. Vlan 1 is the untagged data vlan and Vlan 100 is the tagged voice vlan. Port 23 is connected to an ASA5505 (will be replaced with an ASA5510 soon), port 24 is connected to a second ESW540 both ports (23-24) are set as Trunk. Ports 5-6 are untagged and assigned to VLAN 100 for the Mitel telephone system in Access mode, ports 20-21 are untagged and assigned to VLAN 100 for SIP phones in access mode, all servers connected are set to access mode on vlan 1. Any unused ports are set as Trunk. The second switch had all it's ports set as Trunk. Port 24 on second switch is connected to port 24 on first switch.
Here's when the problems started happening :
When the phones were connected to the ports on the second switch, everything worked fine for a few hours until the phones started loosing connection to the phone controller. PC connected to the network through the phones were still functionning (ie access to Internet). When we moved a phone from second switch to first switch, the phone started working. We then moved the cable that was connected to port 24 of first switch to port 22 of first switch, not long after, the port deactivated itself. We then plugged the same cable to port 11 and so far it seems to be working. After some searching, we disabled STP on ports 11, 22 and 24. BDPU guard was already disabled on port 24 but I went ahead and disabled it on ports 11 and 22. Through the logs, I found out port 22 was deactivated because of BDPU guard which I then reactivated. Is there anything else I need to do on port 24 of the first switch and second switch to allow both VLAN (1 and 100) to pass through permanently?
Thanks,
