Switchport going to Error-disable frequently which is connected to Hub

Hi Friends,

One of our swtich is frequently going to error-disable.

That switch port is connected to a hub and to that two PCs are connected.

Can you please suggest what is the problem and how to solve it.

Switch#sh interfaces gigabitEthernet 0/13

GigabitEthernet0/13 is down, line protocol is down (err-disabled)

Configuration for that particular port

Check if err-disable for storm-control is enabled by doing the following:

NJ-SW#sh errdisable recovery | i storm-control

storm-control Enabled

-


If the output is ENABLED as shown above, please run the following command in config mode:

NJ-SW(config)#no errdisable recovery cause storm-control

and hit enter!!!!!!

Hi Web,

Switch#show errdisable recovery | i storm-control
storm-control                Enabled
Switch(config)#no errdisable recovery cause storm-control
Switch(config)#no errdisable detect cause all
Switch(config)#exit

Just given commands as you suggested

After running the commands, please update if the err disable problem is solved....

I see you said you set the PC's to full duplex, that is incorrect, they need to be hard set to half duplex, hubs only work in half duplex. Also on the port that the hub connects to on the switch you need to also hard code that to half duplex NOT auto. This causes duplex mismatching and will cause the port to erro-disable.

Hi Burleyman,

I will try what you have suggested and I ll reply soon.

Thank you so much for ur time..!!!!

Something is not right here.

If the interface goes into error-disable then the first question I'd be asking is WHY.  To know WHY the port(s) went into error-disable then use the command "sh interface status error".

Next, if the reason is "link flap" (or something in that vicinity) then I'd consider running a TDR

Hi Siva,

try to do this things:

1) clear the counter of interface gi0/13.

2) set the speed and duplex w.r.t hub

3)observe the ouputs of " show interface" (multiple time) .

4) After that if port not stabilizes then try to remove the pc one by one.

Regards,

Palani

Hi sivaalthi,

Can  please tell the model number of switch and hub.

Br.

Mohseen


HI Mohseen,

Its a layer 3 cisco switch and full duplex hub.

Its a layer 3 cisco switch and full duplex hub.

C'mon here.  Mohseen asked a very legitimate question.  Please answer appropriately. 

I have the strange feeling this is a layer 1 issue.  One way of checking is TDR.

Hi,

Sorry Its 3560

*    1 30    WS-C3560X-24P      12.2(53)SE2           C3560E-UNIVERSALK9-M

Ok. That's good. 3560X supports TDR.

1. Command: test cabl TDR int gig 0/13;

2. Wait between 5 to 7 seconds;

3. Command: sh cable TDR int gig 0/13;

4. Please post the output.
