adnRdssGatIfMtu
Module: ADN-ENV-MIB
OID (symbolic): ADN-ENV-MIB::adnRdssGatIfMtu
OID (numeric): 1.3.6.1.4.1.637.3.1.8.5.100.3.1.9
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This field represents the size of the MTU associated with this ifindex.
What is adnRdssGatIfMtu?
This OID stores the Maximum Transmission Unit (MTU) size in bytes for the interface, indicating the largest IP packet that can be sent without fragmentation. Network engineers use this to verify MTU settings match the underlying layer-2 technology and to troubleshoot 'black hole' routing issues where packets are dropped due to size mismatches. For example, an MTU of 1500 is standard Ethernet, but 1492 indicates Frame Relay or PPP encapsulation is in use.
