I'm not in front of an HP, but check out (I think) this file:

/net/interfaces/lan/status/lan0

There are countless ways to parse this,
and several to query the nic's state.
Since you began with awk you could do the
parsing like this e.g.

[[ $(ifconfig lan0|awk -F\< '$2~/UP/{split($2,a,",");print a[1]}') = UP ]] && echo up
