Good afternoon,
Having an issue with VTP propagation. I have two 2950 switches, Switch_1 as VTP server and Switch_2 as VTP Client and both fa0/23 ports are configured as trunks. Switch_1 has four Vlans (vlan 1, vlan 10, vlan 20, vlan 30) but they are not crossing over to Switch_2. Here are some shows:
SWITCH_1:
Switch_1#show ip int br
Interface IP-Address OK? Method Status Protocol
Vlan1 192.168.10.1 YES NVRAM up up
FastEthernet0/1 unassigned YES unset up up
FastEthernet0/2 unassigned YES unset up up

Oddly enough, the port lights on the switch are not illuminated yet vlan 1 on both switches is set to no shutdown.
Anything more I should offer as info?
Thanks

Hi,
Your cable betwen port 23 on the switches needs to be a CROSSOVER
Hope this helps
