Example of subnet routing
Prior to configuring, you must be connected to the switch Command Line Interface (CLI) as the
administrator.
NOTE: For details about accessing and using any of the menu commands described in this
example, see the Command Reference Guide.
1. Assign an IP address (or document the existing one) for each router and client workstation.
In the example topology, the following IP addresses are used:

Devices
IP Addresses
1
Primary and Secondary Default Routers
205.21.17.1 and 205.21.17.2
2
First Floor Client Workstations
100.20.10.2-254
3
Second Floor Client Workstations
131.15.15.2-254
4
Common Servers
206.30.15.2-254
2. Assign an IP interface for each subnet attached to the switch.
Since there are four IP subnets connected to the switch, four IP interfaces are needed

IF 3

IF 4

206.30.15.1
IP interfaces are configured using the following commands at the CLI:
>> # /cfg/l3/if 1 (Select IP interface 1)
>> IP Interface 1# addr 205.21.17.3 (Assign IP address)
>> IP Interface 1# ena (Enable IP interface 1)
>> IP Interface 1# ../if 2 (Select IP interface 2)
>> IP Interface 2# addr 100.20.10.1 (Assign IP address)
>> IP Interface 2# ena (Enable IP interface 2)
>> IP Interface 2# ../if 3 (Select IP interface 3)
>> IP Interface 3# addr 131.15.15.1 (Assign IP address)
>> IP Interface 3# ena (Enable IP interface 3)
>> IP Interface 3# ../if 4 (Select IP interface 4)
>> IP Interface 4# addr 206.30.15.1 (Assign IP address)
>> IP Interface 4# ena (Enable IP interface 4)
3. Set each server and workstation‘s default gateway to the appropriate switch IP interface (the one in
the same subnet as the server or workstation).
