mscBtdsFramerBtdsCellSize

Module: Nortel-MsCarrier-MscPassport-BitTransparentMIB

OID (symbolic): Nortel-MsCarrier-MscPassport-BitTransparentMIB::mscBtdsFramerBtdsCellSize

OID (numeric): 1.3.6.1.4.1.562.36.2.1.81.2.11.1.12

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This attribute allows selection of larger BTDS cell sizes. Larger BTDS cell sizes improve efficiency but increase the minimum egress queue delay. If the associated channel is using less than 5 timeslots (320 kbits/sec), the default btdsCellSize will be used. Setting btdsCellSize to 84 is only allowed on DS1 and E1 FPs.

What is mscBtdsFramerBtdsCellSize?

Selects the internal BTDS cell size (n44 or n84 bytes); larger cells improve bandwidth efficiency but add egress queuing delay, and n84 is only allowed on DS1/E1 cards.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.36.2.1.81.2.11.1.12
snmpwalk -v2c -c public <target> Nortel-MsCarrier-MscPassport-BitTransparentMIB::mscBtdsFramerBtdsCellSize

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.562.36.2.1.81.2.11.1.12.1
snmpget -v2c -c public <target> Nortel-MsCarrier-MscPassport-BitTransparentMIB::mscBtdsFramerBtdsCellSize.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.562.36.2.1.81.2.11.1.12.1 i <value>
