dcxMACDownChannelUpconverter

Module: ARRIS-C3-MAC-MIB

OID (symbolic): ARRIS-C3-MAC-MIB::dcxMACDownChannelUpconverter

OID (numeric): 1.3.6.1.4.1.4115.1.4.3.6.1.2.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Controls whether or not the internal upconverter is used. If set to internal, the downstream IF frequency will operate in read-only mode and will be configured internally by the CMTS based on the downstream channel configuration. If set to external, the IF frequency may be programmed to set the frequency supplied to an external upconverter via the IF output. In this mode, the downstream RF frequency and power will both return 0 when read.

What is dcxMACDownChannelUpconverter?

IF frequency control: internal(1) auto-configured by CMTS, external(2) user-programmable to external converter. Example: internal for standard setup.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4115.1.4.3.6.1.2.1.2
snmpwalk -v2c -c public <target> ARRIS-C3-MAC-MIB::dcxMACDownChannelUpconverter

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4115.1.4.3.6.1.2.1.2.1
snmpget -v2c -c public <target> ARRIS-C3-MAC-MIB::dcxMACDownChannelUpconverter.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.4115.1.4.3.6.1.2.1.2.1 i <value>

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> dcxMACDownChannelUpconverter.1
