tnIPv6LinkMTU
Module: TN-DEV-SYS-IPMGMT-MIB
OID (symbolic): TN-DEV-SYS-IPMGMT-MIB::tnIPv6LinkMTU
OID (numeric): 1.3.6.1.4.1.868.2.5.10.1.9.1.13
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Link MTU maximum transmission unit. Size (in bytes) of the largest protocol data unit.
What is tnIPv6LinkMTU?
This reports the link-layer MTU, in bytes, for this IPv6 interface, as distinct from the (possibly smaller) IPv6 protocol MTU in tnIPv6MTU. An admin compares the two when diagnosing an MTU mismatch affecting IPv6 traffic on this interface.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.868.2.5.10.1.9.1.13 snmpwalk -v2c -c public <target> TN-DEV-SYS-IPMGMT-MIB::tnIPv6LinkMTU
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.868.2.5.10.1.9.1.13.1 snmpget -v2c -c public <target> TN-DEV-SYS-IPMGMT-MIB::tnIPv6LinkMTU.1
