Error Message on CAT4003 v6.3(3a)

What below message does mean?

2002 Dec 19 14:13:05 %PAGP-5-PORTTOSTP:Port 2/4 joined bridge port 2/4

-----------------------

I have PC is connetced to IP Phone and IP Phone connected to SW Port # 2/4.

IP Phone has switch type design (not HUB type) to support 2 different VLANs.

CAT4003 port # 2/4 has native VLAN=3 (PC) and AUX VLAN=99 (voice)

IP Phone sends 802.1p/Q tagged frame on port#2/4

NO ANY TRUNKING

-----------------------

IP Phone remains UP for some time and then reboot.

Any idea what above messages mean? and is it related to rebooting IP Phone.

Thx

Looks like 2/4 is leaving and joining the bridge port. Check for any faulty cabling. You can find explanation of DTP messages on CCO at

If this does not help, move the phone/PC to a different port and see if the problem follows the port or stays with the port. Either the phone port or switch port could be causing this
