Problem with trunking link between switches

[hayabusaukuk]

This is a funny one, i have an old 3com 4900 core switch (old IOS) and a new IOS 4200G distribution switch


Ive done this 100 times, but for some reason i cant get this to work....

4900 GE/9 set to trunk for all Vlans.....

4200G GE/8 set to trunk for all Vlans.....

4200 cant ping 4900?

4200 has ip address and default route of 10.0.0.1 (core switch)

If i set 4900 GE/9 to access for VLAN1 and 4200 GE/8 to access VLAN1 then it pings.....


why, why, why???


Its been driving me mad!


thanks

Sorry, i havent explained that well.....

The issue is that the servers are all on VLAN1, as of course are the switches management vlan.

If i trunk the ports between the together thy cannot ping


BUT the vlans operate correctly, except for VLAN1.

For some reason, workstations that are then plugged into a port on VLAN1 can only see the switches and not see the servers at all.....


I would rather avoid moving the servers from VLAN1 due to software compatability issues

Since the switch is only compatible with Layer 3 static routing, you will probablly need to define a static route for each vlan that you have defined on the switch.
