wfFDDIMtu

Module: Wellfleet-FDDI-MIB

OID (symbolic): Wellfleet-FDDI-MIB::wfFDDIMtu

OID (numeric): 1.3.6.1.4.1.18.3.4.4.1.9

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: The MTU is the maximum allowed frame length on the wire, excluding frame delimiters (i.e. preamble, ending delimiter).

The MTU of an FDDI frame includes: FC (1 octet) + DA (6 octets) + SA (6 octets) + INFO (<= 4478 octets) + FCS (4 octets) = 4495 octets

What is wfFDDIMtu?

Reports the maximum transmission unit for this FDDI interface, fixed at 4495 bytes (1 FC + 6 DA + 6 SA + up to 4478-byte INFO field + 4 FCS octets), the standard FDDI frame ceiling an admin compares against when diagnosing oversized-frame drops.
