We have an existing C3750X-24 stack and have installed a 10GB module to connect to a new HP switch supplied by a vendor.
The hp switch is on a 192.168.40.xx vlan, and they will be responsible for it's configuration.
We are responsible for configuring the cisco switch (currently just the management default vlan1) 192.168.41.xx
IP routing is enabled, and I can create a vlan for the hp's subnet.... just not sure if I only need to add the 10GB module to the HP VLAN, or all the ports?
If I only add the 10GB interface, will all the other ports see it as a gateway and route through the 10GB module automatically?
