Network Configuration

I have a question about a Network config someone setup for us and he is no longer with us.

What does Physical/virtual mean in this situation

192.168.0.7/24 physical

192.168.0.8/24 virtual

for a Switch used as a router with the EMI image, its a 3750G

This is from a network diagram, the firewall is 192.168.0.1/24

My question is what is this physical/virtual mean? and how to configure the switch router for this ?

Re: Network Configuration

The .8 is probably an HSRP address. Do you have a router or another switch that lists this address a virtual address. Can you send the configuration?

Re: Network Configuration

Hi!

By Virtual it means that its an IP address for a virtual interface such as for vlan interfaces running HSRP. So the IP 192.168.0.8/24 is an IP assigned to a HSRP group.

By physical it means that its an IP address given to a physical interface such as a FastEthernet/Serial port. So the IP 192.168.0.7/24 is assigned to a physical interface.

Re: Network Configuration

Ahh Yes it must be HSRP, we are doing 2 redundant EMI 3750 switches as routers for LAN.

Re: Network Configuration

Hi!

So if you check for the IP address on the redundant 3750 you would find it for the same vlan as on the other 3750.

Hope all your doubts were cleared.
