Network Issue(lan card)

[shikhar_1]

Hi,

Its regarding one of my LAN Card (lan4)showing claimed but in operatio status showing down. See the below o/p

I believe Operation state (value) =down(2) indicates that card is not seeing the link from the other side

Can you do an:

# ifconfig lan4 up

What happens?

[shikhar_1]

I tried ifconfig lan4 up but no luck. It is not showing up.

ebzdys01: /etc/rc.config.d # ifconfig lan4 up
ebzdys01: /etc/rc.config.d #  ifconfig lan4
lan4: flags=1843<UP,BROADCAST,RUNNING,MULTICAST,CKO>
        inet 10.15.11.128 netmask ffffff00 broadcast 10.15.11.255
ebzdys01: /etc/rc.config.d #

[Patrick Wallek]

Yes, it is showing UP.

>>  lan4: flags=1843<UP,BROADCAST,RUNNING

Can you ping that IP address now?

[shikhar_1]

Just now it is showing UP, earlier it was not showing UP.

Still i am not able to ping from other servers.

[shikhar_1]

Again it gone down.
