Alteon OS Application Guide

1. Define the VLANs.

For simplicity, both default gateways are configured in the same VLAN in this example. The gateways could be in the same VLAN or different VLANs.

>>

# /cfg/l2/vlan 1

(Select VLAN 1)

>>

vlan 1# add <port number>

(Add a port to the VLAN membership)

2. Define the IP interfaces.

The switch will need an IP interface for each default gateway to which it will be connected. Each interface will need to be placed in the appropriate VLAN. These interfaces will be used as the primary and secondary default gateways for the switch.

>> IP# metrc strict

(Set metric for default gateway)

>> IP# if 1

(Select default gateway interface 1)

>> IP Interface 1# ena

(Enable switch interface 1)

>> IP Interface 1# addr 200.200.200.1

(Configure IP address of interface 1)

>> IP Interface 1# mask 255.255.255.0

(Configure IP subnet address mask)

>> IP Interface 1# ../ip/if 2

(Select default gateway interface 2)

>> IP Interface 2# ena

(Enable switch interface 2)

>> IP Interface 2# addr 210.210.210.1

(Configure IP address of interface 2)

>> IP Interface 2# mask 255.255.255.0

(Configure IP subnet address mask)

3.Enable IP forwarding.

IP forwarding is turned on by default and is used for VLAN-to-VLAN (non-BGP) routing. Make sure IP forwarding is on if the default gateways are on different subnets or if the switch is connected to different subnets and those subnets need to communicate through the switch (which they almost always do).

>> /cfg/l3/frwd on

(Enable IP forwarding)

NOTE – To help eliminate the possibility for a Denial of Service (DoS) attack, the forwarding of directed broadcasts is disabled by default.
