Hello,
I have a pair of Nexus 55594UP with several fexes dual homed.
I have configured a lot of LACP port-channel without problem with a lot of servers. We installed a new Sun Solaris several weeks ago with this config and it works great.
Now we need to install a second Sun Solaris and it doens't works well.
Setup :
One port-channel of two 10gb NIC directly connected in each N5k.
Multiple port-channels of two 1gb NIC connected to the same fex.
The problem is, on all port-channels of this server, one port is "P" and the other is "I" for 1gb cards (#13-14-17). For the 10gbs port-channel (#9), I see "I" on both Nexus
# sh port-channel summary
9 Po9(SD) Eth LACP Eth1/6(I)
13 Po13(SU) Eth LACP Eth111/1/7(I) Eth111/1/8(P)
14 Po14(SU) Eth LACP Eth111/1/9(I) Eth111/1/10(P)
17 Po17(SU) Eth LACP Eth111/1/1(P) Eth111/1/2(I)
Config for the 10gb (same on both N5k)

Do you have any idea ?
On the server we see this message too, which is weird because these aggr and ports numbers doesn't exist on the server and these numbers change randomly :
Jul 25 10:03:30 CT20SSLDCP01 aggr: NOTICE: aggr 45 port 15: Port Partner MAC 0:23:4:ee:be:1 and key 13 in use on aggregation 47 port 18
Jul 25 10:03:31 CT20SSLDCP01 aggr: NOTICE: aggr 45 port 13: Port Partner MAC 0:23:4:ee:be:1 and key 10 in use on aggregation 47 port 8
Thanks !
