Module: CASCADE-MIB

OID (symbolic): CASCADE-MIB::cktBc

OID (numeric): 1.3.6.1.4.1.277.1.6.1.1.5

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The maximum amount of data (bits) that the network agrees to transfer over the circuit under normal conditions, during the measurement interval.

What is cktBc?

This is the Committed Burst Size, the largest chunk of data the network will carry at the committed rate within one measurement interval before additional traffic is treated as excess or discarded. An admin tunes cktBc together with cktCir to control how bursty a customer's traffic is allowed to be while still counting as committed rather than excess. For example, doubling cktBc from 8000 to 16000 bits lets a customer send twice the burst before their traffic is marked as exceeding the committed rate, at the cost of a longer measurement interval T = Bc/Cir.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.6.1.1.5
snmpwalk -v2c -c public <target> CASCADE-MIB::cktBc

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.6.1.1.5.1
snmpget -v2c -c public <target> CASCADE-MIB::cktBc.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.6.1.1.5.1 i <value>
