HP Procurve 2524M Switching off Ports

[TimDunton]

I've noticed in the error log on that a port has gone off line.

I 08/12/06 17:01:27 ports: port 1 is now off-line

I check the port status and it was set to disabled. No other users were connected. Any ideas what might cause this?

Hi

Usually this message caused by LACP, have you enabled Trunking on this port ? or do you have Spanning-Tree running ?

Run the following commands:
25240# config
2524(config)# no interface all lacp
2524(config)# write mem
2524(config)# show lacp

If a port was disabled, then most likely either someone disabled it, or you had port security set to disable the port on a security violation.

Thanks guys. How do I check port security?

[Mohieddin Kharnoub]

Hi

use the commands:

2524# show port-security

If you have the Port Security enabled, then:
under the Action, see if you have Disable Port, then check whats the learn mode.

Good Luck !!!

Thanks mate, I checked that. Looks like it's off to me.

Does anyone else know what would randomly turn a port off? No other users were connected at the time.

HP ProCurve Switch 2524# show port-security

Hi

You have not clarify if this port connects to a Client, Switch or Hub.

Anyway,

In the CLI, type menu, then from the Main Menu, select:
1. Status and Counters . . .3. Port Status

Read the Intrusion Log field, and other port configuration and try to figure out if something wrong.

Good Luck !!!

Hi All,

Are you sure this is isn't a known problem? I've just had it happen again on another 2524M.

I 08/20/06 11:26:48 ports: port 1 is now off-line

Nothing in the intrusion logs by the way. All I can find is that port info.

Hi

It sounds a weird issue you have there.
use HP2512> show logging,
to list all recorded log messages since last reboot.
If you can also attach the configuration of the switch, with little info about the network map.

Good Luck !!!
