Issue with Cisco Catalyst 3550 Switch and G700

[CChambleeJr]

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:

Try this on the switch.

Dasan64,

Implemented your recommended changes to all 24 ports. All ports are now each set at:

interface FastEthernet0/22
switchport mode access

Saved the changes, port still won't green-up. Reloaded switch, no difference. Port and protocol are still in "down" state. Unplugged G700, replugged, no change. The problem has got to be in this switch. I can even connect the G700 to a switch port on my little Netgear wireless router and the port comes up. Four different switches, out of them only the 3550 won't connect. Any more ideas? Can't find any Avaya notes or "best practices" suggestions for the 3550.

Another interesting thing about this issue...

I can connect a port from the Cisco 3550 to port 1 on my Netgear home router, and then connect the G700 to port two on the Netgear router, then all ports show connected and greened-up, and I have connectivity. The 3550 just doesn't like the G700's port for some reason.

mattKnight,

I wish I had looked more carefully at the replies yesterday, I somehow missed yours. Using a crossover cable resolved the problem. Makes little sense to me why the 3550 doesn't do auto MDI-X, while the 3560 does. I have interconnected the Avaya G700's to all kinds of data switches over the past eight years, this is the first time I've had to use a X-over cable. But this is also my first experience with the Catalyst 3550. No wonder the 3550 switches are selling so cheap on eBay. Thanks mattKnight. Thanks also to dasan64 for working with me on this issue, if I had been more observant I'd not have wasted your time.
