h3cPosMTU
Module: A3COM-HUAWEI-PPP-OVER-SONET-MIB
OID (symbolic): A3COM-HUAWEI-PPP-OVER-SONET-MIB::h3cPosMTU
OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.19.1.1.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Maximum Transfer Unit (MTU) of POS interface
What is h3cPosMTU?
This OID sets the maximum size of packets transmitted over the POS interface, with valid values from 64 to 9192 bytes. The MTU affects throughput efficiency and whether fragmentation occurs for large packets. A typical value of 1500 bytes matches Ethernet MTU; higher values reduce fragmentation overhead on long-distance links.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.45.1.10.2.19.1.1.1.2 snmpwalk -v2c -c public <target> A3COM-HUAWEI-PPP-OVER-SONET-MIB::h3cPosMTU
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.43.45.1.10.2.19.1.1.1.2.1 snmpget -v2c -c public <target> A3COM-HUAWEI-PPP-OVER-SONET-MIB::h3cPosMTU.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.43.45.1.10.2.19.1.1.1.2.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> h3cPosMTU.1
