genHdlcMtu
Module: TIARA-GENERIC-HDLC-MIB
OID (symbolic): TIARA-GENERIC-HDLC-MIB::genHdlcMtu
OID (numeric): 1.3.6.1.4.1.3174.2.15.1.1.2
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: Maximum transmission unit ie. the maximum packet size to be sent.
What is genHdlcMtu?
This read-write object configures the Maximum Transmission Unit, the largest packet size the HDLC bundle will send, defaulting to 1500 bytes. Admins adjust it to match the MTU of the underlying link or to avoid fragmentation across a WAN path with a smaller MTU than the default Ethernet-sized 1500. Lowering genHdlcMtu to 1492 might be necessary on a bundle running over a PPPoE-encapsulated path that reserves overhead from the standard 1500-byte MTU.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3174.2.15.1.1.2 snmpwalk -v2c -c public <target> TIARA-GENERIC-HDLC-MIB::genHdlcMtu
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.3174.2.15.1.1.2.1 snmpget -v2c -c public <target> TIARA-GENERIC-HDLC-MIB::genHdlcMtu.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.3174.2.15.1.1.2.1 i <value>
