I think you have to go through and look at each port individually. Use the show spantree (mod/port) command. To enable portfast on a port, use set spantree portfast (mod/port) enable command. And to disable, use the same string, except replace enable with disable( set spantree portfast...

oj88, have you ever heard of a port showing up that was not a physical port? is this another characteristic of redundancy?

If you are only going to have one vlan in your network, you don't need to trunk the connection. But I noticed that Gig0/2 on the 3500 is trunked. If one end of a connection is trunked, the other end must be trunked too for proper operation. You also need to create Vlan 1 on the 2948. To create...

On the 4000 switch, turn the trunk off on 3/17(set trunk 3/17 off dot1q). Then add 3/17 to vlan 1(set vlan 1 3/17). this will make it's native vlan 1. then turn the trunk back on(set trunk 3/17 on dot1q) and your problem should be solved.

You should just put your ip info on Vlan 180. First, shut down interface vlan 1, then put your ip address on interface vlan 180 and make that interface active with the command no shut.

sinecure- I think the designation fmonteiro was talking about is not an actual command, but rather a theory. It all deals with DTE and DCE devices. Data Terminal Equipment and Data Communications Equipment. "Small" devices such as NICs on PCs are considered DTE devices. While switch...

I keep getting this message: %SYS-4-P2_WARN: 4/Invalid traffic from multicast source address 91:3a:83:24:39:1a on port 4/59. But I can't find this MAC address anywhere, and module 4 is a gig module with only 9 ports. Anybody have any ideas on how to handle this?

Did you set up the trunk on the 2948 switch?
