No network connectivity after Ignite Build

All,
I have rebuilt a D250 using an ignite image and now I can't see the network, I have added the relevant server info to netconf and also installed patch J3516A to enable Base T networking.

All thoughts very welcome!!

Thanks in advance
Andy

Re: No network connectivity after Ignite Build

Look at your routing table

nestat -nr

See if you have a default route

if not use route add to restore it

Additionally, make sure your lan card is up

ifconfig lan0 ( or whatever instance your are using

I have a D380 that has a problem where every once in a while after a reboot you have to disconnect the network cable and plug it back in to get link established. i assume the card is claimed in ioscan and you have checked /etc/rc.log for failures. Add more info if you find anything. HTH

Ok, my spelling is bad

netstat -nr

Re: No network connectivity after Ignite Build

Basics to check whenever networking fails:

IP address is correct (netstat -in)
Name resolution is correct (nslookup)
Netmask is correct (ifconfig)
card state (lanscan, ifconfig)
check default gateway (netstat -rn)
ping 127.0.0.1
ping server IP
ping gateway
ping ouside gateway

If pings to gateway fail and network settings appear to be correct, verify the wire with linkloop to another MAC address on the same subnet.
