Description: This attribute indicates the size of the largest packet that can be transported along the selected route. It is used by RouteSelector to select a route which avoids trunks whose maximum transmission unit is less than maximumTransmissionUnit and as a result would be unable to transport packets of this size. The default value of 0 permits all trunks to be eligible with respect to this attribute.

What is mscRtgRsMaximumTransmissionUnit?

Specifies the largest packet size the route must be able to carry; RouteSelector avoids any trunk whose MTU is smaller than this value, with the default of 0 placing no MTU restriction on route selection.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.36.2.1.40.2.12.1.6
snmpwalk -v2c -c public <target> Nortel-MsCarrier-MscPassport-PorsVcMIB::mscRtgRsMaximumTransmissionUnit

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.562.36.2.1.40.2.12.1.6.1
snmpget -v2c -c public <target> Nortel-MsCarrier-MscPassport-PorsVcMIB::mscRtgRsMaximumTransmissionUnit.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.562.36.2.1.40.2.12.1.6.1 i <value>
