svcPrefixNumBits

Module: CASCADE-MIB

OID (symbolic): CASCADE-MIB::svcPrefixNumBits

OID (numeric): 1.3.6.1.4.1.277.5.1.2.1.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The number of valid bits associated with this entry's prefix object. By default, this value will be 8 times the prefix object's octet string length.

What is svcPrefixNumBits?

This read-write value, ranging 1 to 160, specifies the number of significant bits in this port's svcPrefixPrefix, defaulting to 8 times the prefix's octet length, mirroring svcNodePrefixNumBits but scoped to a per-port prefix rather than a node-wide one. This lets an admin configure a partial-byte-length prefix match specific to one port's routing policy. An engineer restricting call routing on a single port to a narrower sub-range than the full prefix bytes would represent would reduce svcPrefixNumBits below the default full-byte-aligned value.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.5.1.2.1.3
snmpwalk -v2c -c public <target> CASCADE-MIB::svcPrefixNumBits

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.5.1.2.1.3.1
snmpget -v2c -c public <target> CASCADE-MIB::svcPrefixNumBits.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.277.5.1.2.1.3.1 i <value>
