wfTokenRingMtu
Module: Wellfleet-TOKEN-RING-MIB
OID (symbolic): Wellfleet-TOKEN-RING-MIB::wfTokenRingMtu
OID (numeric): 1.3.6.1.4.1.18.3.4.2.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: mtu parameter, fixed. This mtu of 4568 allows a type 3 Source Route
Frame (info=4472) to be IP encapsulated over Token Ring.
The components are:
AC_FC (2) +
SNAP (12+8) +
SNAP_IP (12+8+20) +
SR (12+18) +
TYPE3_INFO (4472) +
FCS (4)
---------------------
total 4568 bytesWhat is wfTokenRingMtu?
The fixed MTU for this Token Ring interface, 4568 bytes, sized to allow a type-3 Source Route Frame carrying IP to be fully encapsulated over Token Ring. An admin reads this as a fixed platform constant rather than something to tune, useful mainly for confirming maximum IP packet size on this Token Ring segment.
