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

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
