Solaris link aggregation not working as expected
Hi,
This is Solaris-10 x86 platform.
I am not able to ping gateway associated with aggr50001. I am not getting idea, where could be issue. Please advise.
Code:
# netstat -nr

Routing Table: IPv4

Probably I would like to make igb2 as full duplex, but there is no igb2 interface in ifconfig. All i can see are aggr interfaces. How will I see underlying interface of igb2 ?
Thanks
