EnterasysPortier

This description assumes that router's external port is fe.1.47 and the fiber optic is ge.1.2

• Connect to Switch as descibed in EnterasysGeneralities
• Assign the IP address: set ip address 10.0.90.2 mask 255.0.0.0

• Configure VLAN 1

set vlan name     1 Internal
set vlan egress   1 ge.1.1    untagged
set vlan egress   1 ge.1.2    tagged
set vlan egress   1 fe.1.1-46 untagged
clear vlan egress 1 fe.1.47
set vlan egress   1 fe.1.48   untagged

This sets all ports except fiber-optic to untagged, and removes external port altogether

• Create VLAN 2

set vlan          2
set vlan name     2 External
set port vlan     fe.1.47 2
set vlan egress   2 ge.1.2  tagged
set vlan egress   2 fe.1.47 untagged
