ProCurve 6120XG and variable length subnets
I'm trying to use variable length subnets on a ProCurve 6120XG in a BladeSystem c7000.
We have divided a Class C network up in to 8 subnets, 255.255.255.224. If I go back to a plain Class C it works but does not when using variable length subnets.
Does the 6120XG support variable length subnets?
Thanks!
J.J.

Re: ProCurve 6120XG and variable length subnets
Or are this seperate networks/VLAN's?
In both cases the switch can forward data between ports in the same subnet. This is a layer-2 (switching) communication and has nothing to do with TCP/IP adresses (layer-3).
In the multinet situation you should allready have a router to forward traffic between VLAN's/subnets, else the subnets are isolated and cannot talk to eachother.
If not then the only way to make the switch reachable from all subnets is to give it an adress+subnetmask that matches all subnets.
The normal way to set things up it to create separate VLAN's for each subnet and configure a router to forward traffic between VLAN's/subnets.
As the previous poster mentioned this is a L2 switch you will need an additional router to forward traffic between subnets.

Re: ProCurve 6120XG and variable length subnets
what does work, what doesn't?
- can the switch ping this gateway and vice-versa?
- can the switch telnet to this gateway (vv)?
>>>
ip default-gateway 10.97.221.62
vlan 131
ip address 10.97.221.61 255.255.255.224
tagged 1-17,20-24,Trk1
<<<
looks basically allright
- what is this default gateway?
- on which port is it connected
(possibly somewhere at Trk1?)
- what's the subnet mask on this gateway?
- what's the vlan config of this gateway?

Re: ProCurve 6120XG and variable length subnets
Thanks for the help. We found the issue.
My network guy forgot to put the Layer-2 switch in the route of the up stream switch.
IT (Layer 2) --> Brocade TurboIron 24x (Layer 3)--> ProCurve
once he put that switch from our IT deptartment in there the subnets were able to forward and resolve eachother.
We're working on getting a Layer 2 switch in the lab so we won't have to go so far up to resolve.
Thanks again!
