cadIfDownChannelCACL1Threshold

Module: CADANT-CMTS-DOWNCHANNEL-MIB

OID (symbolic): CADANT-CMTS-DOWNCHANNEL-MIB::cadIfDownChannelCACL1Threshold

OID (numeric): 1.3.6.1.4.1.4998.1.1.15.2.1.1.21

Node type: OBJECT-TYPE

Type: Integer32

Access: read-write

Description: Percentage of available bandwidth on the channel that can be reserved for admitted/active service flows before the channel goes into Level 1 Overload. When a channel goes into Level 1 Overload, a warning message will be logged. Service flow activation/admission will not be denied in Level 1 Overload.

If the percentage is set to 0, the default value will be used and reading this object must return the the default L1 threshold.

If a set operation tries to change the value of an existing instance of this object to any value that is higher than cadIfDownChannelCACL2Threshold or higher than cadIfDownChannelCACL3Threshold on the same row, then an 'inconsistentValue' error must be returned.

What is cadIfDownChannelCACL1Threshold?

Configures the Level 1 Call Admission Control (CAC) threshold as a percentage of downstream bandwidth reserved for admitted and active service flows. When this threshold is crossed, a warning is logged, but new service flow requests are still accepted.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4998.1.1.15.2.1.1.21
snmpwalk -v2c -c public <target> CADANT-CMTS-DOWNCHANNEL-MIB::cadIfDownChannelCACL1Threshold

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4998.1.1.15.2.1.1.21.1
snmpget -v2c -c public <target> CADANT-CMTS-DOWNCHANNEL-MIB::cadIfDownChannelCACL1Threshold.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.4998.1.1.15.2.1.1.21.1 i <value>
