Note the “Hdw State” (Hardware State) of the lan cards. Should be “UP”

Lan cards that are assigned an ip-address:

# grep -i interface_name netconf

# INTERFACE_NAME:     Network interface name (see lanscan(1m))

INTERFACE_NAME[0]="lan1"

INTERFACE_NAME[1]="lan2"

The cards with ip-address assigned should have the interface state UP.

# ifconfig lan1

lan1: flags=843<UP,BROADCAST,RUNNING,MULTICAST>

        inet 194.178.122.10 netmask ffffffc0 broadcast 194.178.122.63

For lan cards that are not assigned a ip-address will report “no such interface”

# ifconfig lan0

ifconfig: no such interface

If the interface state is blank then check the /etc/rc.config.d/netconf file for the INTERFACE_STATE[N]="" parameter value of the interface card.

If value is “down “ then this could be purposefully done.

If the value is “up” or empty “” then the interface has to be UP on a system boot. If so change the interface state of the lan card to UP:

# ifconfig lan1 UP
