I was originally having a problem with DHCP on a M$ 2003 server. That has been resolved. The new problem that I have is I can't ping ANY statically assigned addresses (workstations, printers, switch)(41.xxx) on vlan 43 (43.xxx). I am trying to leave my static stuff (41.xxx) alone for the time being until I can go around and change. As you can see below, I've added vlan 41 access to the trunk but I still am unable to ping anything with a 41.xxx address.

see the related config:

Anyone have a clue? I am thinking that I need the following route:

ip route add 192.168.43.1 255.255.255.0 192.168.41.1 (or 192.168.41.1 255.255.255.0 192.168.43.1).

thanks in advance.
 
As long as ip routing is turned on the 4506 you should not have to add any routes , it knows about attached interfaces or defined routes on the 4506 . It appears the trunk between the 4506 and 3com is not working and only passing vlan 41 . Not knowing anything about 3coms I really can't help there . I would try to dig up documentation on how to implement trunking on your 3coms . On the 3com you would have to verify the trunk is working and also you would have to put the ports into the correct vlan on the 3com , any .41 addressed ports would have to be set to vlan 41 and the .43 would have to be assigned to vlan 43 .
 
thanks for the reply.

would would be the default route for all my 41.xxx statically assigned devices? would it be 41.1 or 43.1?

thanks again.
 
for the 41 net it would be this , just look at your standby ip address for each defined vlan ,standby 41 ip 192.168.41.1 .
The .43 would be ip 192.168.43.1
