Configuration Examples

VLANs are used to associate physical ports on the SSR with connected hosts that may be physically separated but need to participate in the same broadcast domain. To associate ports to a VLAN, you must first create a VLAN and then assign ports to the VLAN. This section shows examples of creating an IP or IPX VLAN and a DECnet, SNA, and AppleTalk VLAN.

Creating an IP or IPX VLAN

In this example, servers connected to port gi.1.(1-2) on the SSR need to communicate with clients connected to et.4.(1-8). You can associate all the ports containing the clients and servers to an IP VLAN called ‘BLUE’.

First, create an IP VLAN named ‘BLUE’

ssr(config)# vlan create BLUE ip

Next, assign ports to the ‘BLUE’ VLAN.

ssr(config)# vlan add ports et.4.(1-8),gi.1.(1-2) to BLUE
