rdnIfCmtsCmStatusRxUnicastKbytes

Module: RDN-CMTS-MIB

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

OID (numeric): 1.3.6.1.4.1.4981.2.2.8.1.3

Node type: OBJECT-TYPE

Type: Counter32

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 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. This is 32-bit version of rdnIfCmtsCmStatusRxUnicastExtKbytes, included to provide back compatability with SNMPv1 managers.

What is rdnIfCmtsCmStatusRxUnicastKbytes?

Read-only 32-bit Counter of unicast KBytes the CMTS has received upstream from this modem; for an offline modem it holds the total from when it was last online, and persists across reboots except when the modem re-registers on a new spectrum group. Like its Tx counterpart, this 32-bit version exists for SNMPv1 compatibility alongside the 64-bit rdnIfCmtsCmStatusRxUnicastExtKbytes.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4981.2.2.8.1.3
snmpwalk -v2c -c public <target> RDN-CMTS-MIB::rdnIfCmtsCmStatusRxUnicastKbytes

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4981.2.2.8.1.3.1
snmpget -v2c -c public <target> RDN-CMTS-MIB::rdnIfCmtsCmStatusRxUnicastKbytes.1
