Here's the scenario. I have two separate G700's with 8300's, each one an independent PBX. Both have been working in my lab for a couple of weeks. I am using a Cisco Catalyst 3560 48-port switch, freshly initialized, with mostly default values other than defining passwords and VLan1 IP address for admin via Telnet. Both G700's make a good connection to the 3560 switch, and I see no problems with connectivity. Today I switched the 3560 out with a newly-acquired Cisco 3550 24-port switch, also default value initialized. The six IP phones, and Dell OptiPlex utility server connect to the new 3550 switch and "green-up", and have connectivity. But neither G700 will green-up to any ports on the 3550. Show interface on the 3550 shows that the line and protocol are DOWN. I've tried six different ports on the 3550, as well as both Ext1 and Ext2 on the G700. Swapped Ethernet cables, no difference. I can move the cable down to the 3560 switch and plug it into any port, and it greens up fine. Unplug and move it back to the 3550 switch, it will not green-up. Something about that 3550 switch won't link up to the G700's LAN ports. I've tried setting port to full duplex, 100mb, 10mb, no shut, and back to auto everything. No link. IP phones and computers all green and connected, just won't accept the G700's connectivity. Anyone seen this before? I've also got a Brocade FastIron 24-port PoE switch at the bottom of my stack of network switches, the G700's link up to it fine, as well. What is it about this Catalyst 3550 switch?
Here's my 3550's configuration:
