ExtremeWare 7.2e Installation and User Guide 221
Verifying the IP Unicast Routing Configuration
Use the show iproute command to display the current configuration of IP unicast routing for the
switch, and for each VLAN. The
show iproute command displays the currently configured routes, and
includes how each route was learned.
Additional verification commands include:
• show iparp—Displays the IP ARP table of the system.
• show ipfdb—Displays the hosts that have been transmitting or receiving packets, and the port and
VLAN for each host.
• show ipconfig—Displays configuration information for one or more VLANs.
Routing Configuration Example
Figure 43 illustrates a switch that has three VLANs defined as follows:
• Finance
— Contain ports 5 and 6.
— IP address 192.207.35.1.
• Personnel
— Contain ports 21 and 22.
— IP address 192.207.36.1.
Figure 43: Unicast routing configuration example
In this configuration, all IP traffic from stations connected to ports 5 and 6 have access to the switch by
way of the VLAN Finance. Ports 21 and 22 reach the switch by way of the VLAN Personnel..
The example in Figure 43 is configured as follows:
create vlan Finance
