Re: uplink Problem Catalyst 2950

Hello,

I assume the uplink port is a trunk port ? Can you post the output of 'show interfaces x', where 'x' is the uplink port ? Do you have any redundant uplinks (which could cause a spanning tree loop) ? Which D-Link model do you have ?

Regards,

GP

Re: uplink Problem Catalyst 2950

Hi!

Pls tell me:-

1)Are you using uplink port of D-Link Switch?

2)Are you using Crossover cable to connect both the switches?

In case of (1)try using a straight cable.

In case of (2)try connecting it with port 3 of cisco and port 3 of D-link, which are not upilnk/trunk etc

Above should solve ur problem on physical layer.If that dose not help,give the 'show interface fx' output.

Re: uplink Problem Catalyst 2950

Hello,

can you try and change your physical setup ? From what I understand from your post, your setup looks like this:

Cisco Switch --> D-Link Switch --> PacketWave Modem

Can you try and change this to:

D-Link Switch --> Cisco Switch --> PacketWave Modem

that is, connect the Cisco switch to the PacketWave modem, and the D-Link switch to the Cisco switch ?
