Hi all,
we have ucs fabric interconnect which connect to vPC domain (2 nexus 7ks), each fabric interconnect has 8 uplinks to 7k paris (4 uplinks for each 7k)
those 2 Nexus7k are running on the same firmware and ucs fabric interconnect connect to the same module and port of two 7k.
So basically, everything is same on two 7k.
On 7k-2, all ports in vpc port channel from ucs fabric interconnect are up.
But on 7k-1, we have 2 ports down which shows "hot standby in bundle"
7k-1# show int e9/6
Ethernet9/6 is down (Hot standby in bundle)

we have not define MaxBundle (the maximum number of bundled ports allowed in a LACP port channel)
any idea about this?
