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 Operational Mode: trunk Administrative Trunking Encapsulation: dot1q Operational Trunking Encapsulation: dot1q Negotiation of Trunking: On Access Mode VLAN: 1 (default) Trunking Native Mode VLAN: 2 (interna) Voice VLAN: none Administrative private-vlan host-association: none Administrative private-vlan mapping: none Administrative private-vlan trunk native VLAN: none Administrative private-vlan trunk encapsulation: dot1q Administrative private-vlan trunk normal VLANs: none Administrative private-vlan trunk private VLANs: none Operational private-vlan: none Trunking VLANs Enabled: 2,100 Pruning VLANs Enabled: 2-1001 Capture Mode Disabled Capture VLANs Allowed: ALL Protected: false Appliance trust: none

And for switch LISAN006

Both ligths are grenn and blinking.
I'm able to ping LISAN006 but not LISAN017. WHY????
Best regards and thaknx,
