Can a Catalyst 3750 switch replace a HP procurve switch without much configuration?
other than configuring the ports, there just needs to be a route on the 3750 pointing all traffic to the gateway correct?
does the remote switch connect to a router?
or is it just a fiber run to another building?
Not sure I understand what the topology is.
If you are connecting to the remote site via WAN router then the vlan number doesnt matter. You are routing subnets not vlans. The default route for client will be that of the remote router
at its simplest form, you should put all ports into the vlan and manage through the vlan interface.
if you are extending the vlan from your office across layer two, then just add users ports to the vlan, and create another ip address for the switch
then all you will need is a IP address and default gateway for management access to the switch.
Conf t - interface vlan X
ip address x.x.x.x x.x.x.x
ip default gateway x.x.x.x
