dead gateway error

[himacs]

Hi Admiins

OS B.11.31

Getting below error.

vmunix: Dead gateway detection can't ping the last remaining default gateway at 0xa8ef901 .See ndd -h ip_ire_gw_probe for more info.

The server is not able to ping to its gateway.But other servers in the same ip series are able to ping.

I have disabled dead gateway feature like below.

ndd -set /dev/ip ip_ire_gw_probe 1

But issue still persists.

Please guide me.

Thanks in advance.

That doesn't disable dead gateway detection, it enables it.  To disable it you must set it to '0'.

ndd -set /dev/ip ip_ire_gw_probe 0

You must also set it up in /etc/rc.config.d/nddconf so that it will persist between reboots.

Have you checked your network to make sure your card is enabled?  Can you ping other devices on the same subnet?

You may need to stop / start networking:

# /sbin/init.d/net stop

# /sbin/init.d/net start

or reboot the server.

you should take a network trace from router & system at nic layer of a ping to the gateway, and check the interface and mac addresses used.

if the router can be pinged, disabling the dgd will not help

 are you using srp or changed ip strong es model?
