Hello,
I'have connected two catalyst 2950T switch together using 10/100/1000 ports, the status led for those ports are green on both switchs, but link is not working (no communication between the two switchs)
Console port gives continuous messages indicating "port up" and then "port down" few seconds after and so on.
Switchs are operating in basic configuration.
Can anybody help me to solve this problem.
Many thanks

What types of cable are you using, straight or cross over

Hello,
I'm using a four pairs UTP crossover cable as indicated in the installation guide.

Hello,
Both switches are in factory default configuration.

Factory default port setting is usually used when connecting a PC and not for casecading to another switch.
For example if you are casecading Port 10 on Switc1 to Port26 on Switch2, then you need to configure both switches as follows
Switch1#( interface 10) switchport mode trunk
Switch2#( interface 24) switchport mode trunk
and make sure you use Xover cable to connect them.
You will need to configure both switches and save the config, factory default will not help when you have more than 1 switch in a LAN.

Hello,
In factory default configuration, all ports (FastEthernet and GigabitEthernet) are set to dynamic desirable mode in order to allow autonegotiation for trunk links. So it wouldn't be necessary to configure GigabitEthernet ports on both switchs to work in trunk mode, because they do it automatically.
