msBitStuffing
Module: ACMIB
OID (symbolic): ACMIB::msBitStuffing
OID (numeric): 1.3.6.1.4.1.1751.2.18.2.4.1.18
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: When msBitStuffing is enabled, CAC throughput is (1 + 1/7) user throughtput. Otherwise the CAC throughput is the same as the user throughput. msBitStuffing can only be enabled for circuit emulation interfaces.
What is msBitStuffing?
This OID enables or disables bit stuffing, a technique that increases the signaling overhead on the circuit emulation interface by padding extra bits (the overhead is 1 extra bit per 7 data bits). A network engineer enables this only when required for circuit emulation compatibility with specific ATM adaptation layer requirements. For example, if you enable bit stuffing on a 64 kbps circuit, the actual line throughput increases to about 73 kbps (64 × 9/8), consuming more bandwidth than pure user data.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.4.1.18 snmpwalk -v2c -c public <target> ACMIB::msBitStuffing
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.2.4.1.18.1 snmpget -v2c -c public <target> ACMIB::msBitStuffing.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.2.4.1.18.1 i <value>
