nngenHdlcMtu
Module: GENERIC-HDLC-MIB
OID (symbolic): GENERIC-HDLC-MIB::nngenHdlcMtu
OID (numeric): 1.3.6.1.4.1.562.73.1.1.1.15.1.1.2
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: Maximum transmission unit ie. the maximum packet size to be sent.
What is nngenHdlcMtu?
This is the maximum transmission unit configured for a Generic HDLC bundle, the largest packet size the system will send, defaulting to 1500 bytes. An admin adjusts this to match the MTU expected by the peer device or to accommodate encapsulation overhead on the bundled WAN link. For example, setting nngenHdlcMtu below 1500 might be needed if the bundle carries an additional tunneling header that would otherwise cause fragmentation.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.73.1.1.1.15.1.1.2 snmpwalk -v2c -c public <target> GENERIC-HDLC-MIB::nngenHdlcMtu
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.562.73.1.1.1.15.1.1.2.1 snmpget -v2c -c public <target> GENERIC-HDLC-MIB::nngenHdlcMtu.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.562.73.1.1.1.15.1.1.2.1 i <value>
