rdnCmtsUSUnregisteredModemCount

Module: RDN-CMTS-MIB

OID (symbolic): RDN-CMTS-MIB::rdnCmtsUSUnregisteredModemCount

OID (numeric): 1.3.6.1.4.1.4981.2.1.2.1.8

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: When read, this object returns the number of unregistered Cable Modems per upstream. This count reflects modems that are in the process of attempting to join the network. Note that this does not include offline modems, see rdnCmtsUSOfflineModemCount for offline modems.

What is rdnCmtsUSUnregisteredModemCount?

Read-only integer (0-2147483647) giving the number of modems currently attempting to join the network on this upstream (in-progress registration), excluding modems that are fully offline (see rdnCmtsUSOfflineModemCount). A persistently high count here suggests modems are struggling to complete registration on this upstream, worth investigating for RF or DHCP issues.

Examples
