docsDevRole
Module: EXP-DOCS-CABLE-DEVICE-MIB
OID (symbolic): EXP-DOCS-CABLE-DEVICE-MIB::docsDevRole
OID (numeric): 1.3.6.1.3.83.1.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Defines the current role of this device. cm (1) is a Cable Modem, cmtsActive(2) is a Cable Modem Termination System which is controlling the system of cable modems, and cmtsBackup(3) is a CMTS which is currently connected, but not controlling the system (not currently used).
In general, if this device is a 'cm', its role will not change during operation or between reboots. If the device is a 'cmts' it may change between cmtsActive and
cmtsBackup and back again during normal operation. NB: At this time, the DOCSIS standards do not support the concept of a backup CMTS, cmtsBackup is included for completeness.
What is docsDevRole?
This reports what role this DOCSIS device is currently playing: cm(1) for a cable modem, cmtsActive(2) for a CMTS actively controlling the system, or cmtsBackup(3) for a standby CMTS (not currently used by the DOCSIS standard). Admins check this to confirm they're looking at a modem versus a headend controller when interpreting the rest of the MIB.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.3.83.1.1.1 snmpwalk -v2c -c public <target> EXP-DOCS-CABLE-DEVICE-MIB::docsDevRole
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.3.83.1.1.1.1 snmpget -v2c -c public <target> EXP-DOCS-CABLE-DEVICE-MIB::docsDevRole.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> docsDevRole.1
