cmEthernetAccPortOamLocalMaxPDUSize

Module: CM-FACILITY-MIB

OID (symbolic): CM-FACILITY-MIB::cmEthernetAccPortOamLocalMaxPDUSize

OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.1.1.56

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: This object represents the largest OAMPDU, in octets, supported by the Ethernet Access Port. This value is compared to the remote Maximum PDU Size and the smaller of the two is used.

What is cmEthernetAccPortOamLocalMaxPDUSize?

This read-only Integer32 reports the largest OAMPDU, in octets, supported by the Ethernet Access Port; the smaller of this and the remote value is what actually gets used. It tells an administrator the effective negotiated OAMPDU size ceiling for OAM sessions on this port. For example, the local max reads 1518 while the remote reports 1500, confirming 1500 bytes is the size actually used in OAM exchanges.
