Q: When do we see duplicate VCs in Central?
A: When do we see duplicate VCs in Central as shown below?
The issue arises with 2+ APs in a swarm.
AP APstatus guid status
I1 Master S1 UP
I2 Slave S1 UP
I3 Slave S1 UP
Lets say One master and one slave goes down. The other slave AP becomes master. Here other AP is getting another guid (split instead of swap).
AP APstatus guid status
I1 Master S1 Down
I2 Slave S1 Down
I3 Master S2 UP
Now when the previous master I1 comes up. It joins the new swarm.
We get two swarm entries, one with new guid with 1 master & 1 slave and other guid with 1 slave as shown below.
AP APstatus guid status
I1 Slave S2 UP
I2 Slave S1 Down
I3 Master S2 UP
As there is no Master for swarm S1 and still it holds this slave entries in the system which is causing duplicate entries in Aruba Central database.
The issue will be fixed when the l2 comes up and join S2 or creates new swarm entry for swarm S1.
