How can I test link aggregation?
Hi,
I have Solaris-10 server and link aggregation is configured on this in below way
Code:
# dladm show-aggr
key: 1 (0x0001) policy: L4      address: 3c:d9:2b:ee:a8:a (auto)
           device       address                 speed           duplex  link    state
           bnx1         3c:d9:2b:ee:a8:a          1000  Mbps    full    up      attached
           igb2         f4:ce:46:a7:eb:92         1000  Mbps    full    up      attached

There will be switch replacement, so one by one, link will go down from one side. Before that activity, is there any way to check/test, if server will work fine, if one side goes down ? In same way, as used to check by if_mpadm -d in ipmp.

Thanks
