Simple VTP Lab question.

mgmguy1

Team,
I am trying to get a simple VTP lab working with two switches and I think my issue is that my packet tracer 5.3.2 is limited on the command.
Here is the output I am getting

Switch(config-if)#spanning-tree vlan 1?
WORD

Switch(config-if)#spanning-tree vlan 1 cost 18

Can anyone please confirm if my suspicion is correct about packet tracer.

Yep, looks to be an issue with Packet Tracer itself, not your syntax. I just tested it on PT and on a 2950 I have sitting on my desk, here was the output.

From Packet Tracer 5.3.2 on a 2960 switch

Switch(config-if)#spanning-tree vlan 1 ?
  port-priority  Change an interface's spanning tree port priority

From a real 2950

Switch(config-if)#spanning-tree vlan 1 ?
  cost           Change an interface's per VLAN spanning tree path cost
  port-priority  Change an interface's spanning tree port priority


Switch(config-if)#spanning-tree vlan 1 cost ?
  <1-200000000>  Change an interface's per VLAN spanning tree path cost

Looks like PT only supports changing the port priority, not the cost.
Hope that helps!

Thank you yes it does. It's frustrating that packet tracker has these limitations and I worry about the test and if Packet Tracer will be enough for the test? I am having fun learning thou and that is the important thing I guess.

I am using PT and GNS3 extensively, but I do have a real 2950 and 2610xm to throw commands at. When I'm using freeccnaworkbook.com sometimes I notice a command (like VTP/STP commands) that won't work properly. When I hit one of those I just throw it on the real switch to make sure I know what I'm doing and then back to the sims!

You can get a 2950 from routerswholesale.com for ~$25 for a 12-port, if you wanted one just to play with.
