Cabletron Systems 9A100 manual 90.1.1.254, Route NET Table

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

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