I'm using cisco 10k cmts on my network. I recently started using Zcorum and for some reason they are not able to poll all the modems. When i do the show snmp sessions command it does not show all modems. I have this problem on 3 out of my 4 cmts. The first cmts shows all the modems when i perform the command bu the other 3 does not and they are all set up the same. I don't know where to start checking.
