POST error Catalyst 2950

I have a Catalyst 2950 series 12 prt. switch. When the switch is booting I receive the following error: "00:00:13: POST: Packet DA mismatch on port: 9"

What does this message means? Can I still use this port?

Kind regards,

Re: POST error Catalyst 2950

This is part of the power on self test(POST).

The switch sets the interface to loopback and sends

a packet. If anything is wrong or changed with

the packet then you get an error. In this case

the DA (destination address) was changed on

the received packet. I assume since this is a

switch they are referring to the layer2 address.

I would think this would indicate a possible hardware

failure.

Hi Nabib,

Thanks for the information.

I thought also that this is a hardware issue.
