IP Routing Switch Administration
Note SmartSwitch 9A100 IP routing performance is inadequate for routing between
VLANs. If you need to create routes between VLANs on your
SmartSwitch 9A100, use a router equipped with an ATM interface. Consult
Cabletron Customer Support for recommended routers.
For example,
• Switch SW1 and the NMS are on an Ethernet network with address 128.205.99.0.
• The IP address of SW1's Ethernet port is 128.205.99.254.
• The IP address of SW1's LANE client is 90.1.1.254.
• The IP address of SW2's LANE client is 90.1.1.33.
• SW2 is not physically connected to the Ethernet network.
• SW2 is connected to SW1 through PNNI, and are both part of the same emulated LAN.
To reach SW2 with the Ethernet-based NMS, create an IP route that assigns SW1's switch client as SW2's default
gateway to the network 128.205.99.0. Enter the following on SW2 (see Figure 4-3):
SmartSwitch # add route
DestNetIP() : 128.205.99.0 < address of the Ethernet network to reach
GatewayIP() : 90.1.1.254 < IP address of SW1's LANE client
SmartSwitch #
Switch SW2 can communicate with the NMS on the Ethernet network.
To see the route, enter the show route command on SW2
SmartSwitch # show route

Note The NMS must contain a route that specifies the Ethernet interface of the Ethernet
connected switch as the gateway to the ELAN subnet.
