usdEthernetIfMtu

Module: Unisphere-Data-ETHERNET-MIB

OID (symbolic): Unisphere-Data-ETHERNET-MIB::usdEthernetIfMtu

OID (numeric): 1.3.6.1.4.1.4874.2.2.34.1.1.1.1.4

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The configured maximum transfer unit (MTU) for this ethernet interface. The operational value is reported in the corresponding Interfaces MIB ifMtu object.

What is usdEthernetIfMtu?

This read-write integer, constrained to the range 64 to 9188 bytes with a default of 1518, sets the configured maximum transfer unit for an Ethernet interface. The value actually in effect on the wire is reflected back through the standard Interfaces MIB ifMtu object, so this object represents the requested configuration rather than a live measurement. An admin would raise this toward 9188 to enable jumbo frames on a link that supports them, or leave it at the 1518-byte default for standard Ethernet framing.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.34.1.1.1.1.4
snmpwalk -v2c -c public <target> Unisphere-Data-ETHERNET-MIB::usdEthernetIfMtu

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4874.2.2.34.1.1.1.1.4.1
snmpget -v2c -c public <target> Unisphere-Data-ETHERNET-MIB::usdEthernetIfMtu.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.4874.2.2.34.1.1.1.1.4.1 i <value>
