rtgRsMaximumTransmissionUnit

Module: Nortel-Magellan-Passport-PorsVcMIB

OID (symbolic): Nortel-Magellan-Passport-PorsVcMIB::rtgRsMaximumTransmissionUnit

OID (numeric): 1.3.6.1.4.1.562.2.4.1.40.2.12.1.6

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

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 rtgRsMaximumTransmissionUnit?

Sets the largest packet size the selected route must support, so RouteSelector avoids trunks whose MTU is too small; a default of 0 makes all trunks eligible regardless of MTU. Raise it above 0 when a connection needs to carry larger packets without fragmentation across the route.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.40.2.12.1.6
snmpwalk -v2c -c public <target> Nortel-Magellan-Passport-PorsVcMIB::rtgRsMaximumTransmissionUnit

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.562.2.4.1.40.2.12.1.6.1
snmpget -v2c -c public <target> Nortel-Magellan-Passport-PorsVcMIB::rtgRsMaximumTransmissionUnit.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.562.2.4.1.40.2.12.1.6.1 i <value>
