h3cIfMtu
Module: A3COM-HUAWEI-IF-EXT-MIB
OID (symbolic): A3COM-HUAWEI-IF-EXT-MIB::h3cIfMtu
OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.40.2.3.2.1.2
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The size of the largest datagram which can be sent/received on the interface, specified in octets. For interfaces that are used for transmitting network datagram, this is the size of the largest network datagram that can be sent on the interface.
What is h3cIfMtu?
Specifies the maximum transmission unit (MTU) in octets—the largest packet size the interface can send or receive. Setting correct MTU prevents fragmentation and improves throughput; mismatches cause packet loss. A typical value is 1500 bytes for Ethernet, or 9000 for jumbo frames.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.45.1.10.2.40.2.3.2.1.2 snmpwalk -v2c -c public <target> A3COM-HUAWEI-IF-EXT-MIB::h3cIfMtu
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.43.45.1.10.2.40.2.3.2.1.2.1 snmpget -v2c -c public <target> A3COM-HUAWEI-IF-EXT-MIB::h3cIfMtu.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.43.45.1.10.2.40.2.3.2.1.2.1 i <value>
