Hi: I have a Catalyst 2924 switch. Last night 4 ports (13 through 16) stopped functioning. Their status light are in a solid (non blinking) YELLOW state.
Any suggestions?
Thanks, Paul

Time to send it in on contract?
Or deal with 4 bad ports if all the rest work.
Hi Paul,
If you are not under contract you may wish to get a "repair or replacement quote" from Reggie Grant:

OK, so far there seems to be a consensus that service is needed. Was just reviewing the manual, and thought that I'd ask.
For Port LED status, it says that "Solid Amber" means:
"Port not forwarding. Port was disabled by management or an address violation, or blocked by Spanning-Tree Protocol (STEP)".
Is it possible that it's not a hardware failure? Any way to verify?
Thanks, Paul
It appears that the ports may be in errdisable state.
If so
conf t int fa 0/13 shut no shut
.....
may fix it.
Note, the LEDs are multi-color, and amber != yellow. Solid Yellow is bad. Solid amber is blocked by something else.
In my experience (lots of lightning strikes out at MUDs and idiot wiring contractors who ran ethernet up under the ridge line), the ports tend to blow in units of 4, and solid yellow on all the time, even after a power cycle means the switch needs to be repaired/replaced. Usually, you'll get the ports failing their POST upon a power cycle, and you can check the logs after a boot for that. Not always though.
If you were blocking for STP, or some other soft error state, it would be amber, and a block of all 4 typically wouldn't be all at once.
Here are the results for Port 14
********************************************** Switch(config-if)#int fa 0/14 Switch(config-if)#shut Switch(config-if)# 17:55:56: %LINK-5-CHANGED: Interface FastEthernet0/14, changed state to administ ratively down Switch(config-if)#no shut Switch(config-if)# 17:56:13: %LINK-3-UPDOWN: Interface FastEthernet0/14, changed state to up 17:56:13: %LINK-3-UPDOWN: Interface FastEthernet0/14, changed state to down **********************************************The last line appears that it goes right back to state down. Ideas?
Thanks again

If the eth controllers have gone bad (and we had a ton of the 2900xls do this), they won't show up when you do a sho ver. You'll see 20 IEEE Fast Ethernet Interfaces (instead of 24). That should erase all doubt.
cSure enough, just shows 20. Thanks. Paul
