I'm working on a CUCM 7 Cluster with 7 nodes: 1 PUB, 4 SUB and 2 TFTP servers.
Recently, on subscriber had stopped working, and since then, IP phones are unable to register once they unregister.
I have checked on the RTMT, I have noticed the loss percentage of 20% on the TFTP servers.
Can you, guys, give me any tips on how to solve this issue?
Thanks in advance, guys
Do you see any spike in CPU , memory etc for these two
