Why the cluster interfaces are showing as "Partially UP"

[Sukdeep_Singh]

Multiple interfaces (Bond & Physical) showing as Partially UP.

What could be reason behind this? 

As per sk106488 . Tried installing JumboHotfix Take_216 but after that few of the interfaces were not visible in Smartview monitor as well as in CLI cphaprob.

 4200 series - R77.30 - No jumbohotfix.

What could be the reason of this behavior?

I had a similar issue . probably you are not receiving any signal from some vlans in your network . it will happen when you loos one of your member because before the faileover you have received the signal from other member .  check your switch trunk and make sure that vlan is reachable to your end point

Cluster interfaces are showing as "Partially UP" when something is wrong with multicast packets. You can check it with a tcpdump.

Command: tcpdump -nneei <interface/bond> port 8116

As example you can see here, that the multicast check only communicates with the broadcast.

00:00:00:00:e6:00 > ff:ff:ff:ff:ff:ff

00:00:00:00:e6:01 > ff:ff:ff:ff:ff:ff

00:00:00:00:e6:00 > 01:00:5e:7c:aa:aa

00:00:00:00:e6:01 > 01:00:5e:7c:aa:aa is missing

In this case, its mostly the configuration of the switch. Cisco calls it “querying”.
