Hello all!
What is missing?

Ok here goes?

I wnat to connect two Catalys 2950 in a trunk mode. The connection is
made using port 48 from switch LISAN017 to port 20 of switch LISAN006.

Here is the configuration for switch LISAN017

LISAN017#show interface FastEthernet 0/48 switchport
Name: Fa0/48
Switchport: Enabled
Administrative Mode: trunk

Administrative private-vlan trunk encapsulation: dot1q
Administrative private-vlan trunk normal VLANs: none

Trunking VLANs Enabled: 2,100
Pruning VLANs Enabled: 2-1001
Capture Mode Disabled
Capture VLANs Allowed: ALL
Protected: false

LISAN017#show interfaces trunk

Both ligths are grenn and blinking.

I'm able to ping LISAN006 but not LISAN017. WHY????

Best regards and thaknx,

Did you use a crossover cable, just wondering?

I don't think he would have a link light ... if he wasn't using a
cross. I am not 100% positive ... I think I'll go test that out.

Pruning VLANs Enabled: 2-1001: if the vlans are pruned on the link how will
they communicate ?

This will only allow vlan 1 across the link. To test this theroy disable
pruning and use switchport trunk allowed

also confirm that the vlans are in the vlan database (this one has caught me
out a few times)
