systemMTU
Module: NMS-HAL-GLOBAL-MIB
OID (symbolic): NMS-HAL-GLOBAL-MIB::systemMTU
OID (numeric): 1.3.6.1.4.1.11606.10.9.1.1.1.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: System MTU. Unit is 1byte. Default value is 1510bytes.
What is systemMTU?
This field sets the system-wide maximum transmission unit size, in bytes. Admins raise this above the standard 1500-byte Ethernet MTU, to the 1510-byte default, when jumbo or tagged frames need to pass through without fragmentation. For example, leaving systemMTU at its 1510-byte default accommodates a standard 1500-byte payload plus VLAN tag overhead.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.11606.10.9.1.1.1.1.2 snmpwalk -v2c -c public <target> NMS-HAL-GLOBAL-MIB::systemMTU
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.11606.10.9.1.1.1.1.2.1 snmpget -v2c -c public <target> NMS-HAL-GLOBAL-MIB::systemMTU.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.11606.10.9.1.1.1.1.2.1 i <value>
