rdnIfCmtsCmStatusRxUnicastExtKbytes

Module: RDN-CMTS-MIB

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

OID (numeric): 1.3.6.1.4.1.4981.2.2.8.1.5

Node type: OBJECT-TYPE

Type: Counter64

Access: read-only

Description: When read, this object will return the number of unicast KBytes (1024 bytes) the CMTS has received from the modem (Upstream Direction). For offline modems this value is the the total number of unicast KBytes when it was online. This object is never reset as long as the CMTS is up. It does not need to be restored across reboots. However, when the CM reregisters into a new spectrum group, this data must be restored.

What is rdnIfCmtsCmStatusRxUnicastExtKbytes?

Read-only 64-bit Counter of unicast KBytes the CMTS has received upstream from this modem, the extended-range counterpart of rdnIfCmtsCmStatusRxUnicastKbytes. Admins use the 64-bit counters instead of the 32-bit ones on busy modems to avoid counter wraparound between polls.
