4-8 SmartCell ZX-250 User Guide
IP Routing Switch Administration
2p›F SmartCell ZX-250 IP routing performance is inadequate for routing between
VLANS. If you need to create routes between VLANs on your SmartCell ZX-250,
use a Cabletron recommended router equipped with an ATM interface. Consult
Cabletron Customer Support for router product information.
For example,
† Switch SW1 and the NMS are on an Ethernet network with the 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, define an IP route on SW2 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):
SmartCell ZX # 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

Switch SW2 can communicate with the NMS on the Ethernet network. To see the route, enter the show route
command on SW2.
SmartCell ZX # show route

2p›F The NMS must contain a route that specifies the Ethernet interface of the Ethernet
connected switch as the gateway to the ELAN subnet.
