dot1dSrPortLargestFrame
1.3.6.1.2.1.17.3.1.1.6
The maximum size of the INFO field (LLC and
above) that this port can send/receive. It does
not include any MAC level (framing) octets. The
value of this object is used by this bridge to
determine whether a modification of the
LargestFrame (LF, see [14]) field of the Routing
Control field of the Routing Information Field is
necessary. Valid values as defined by the 802.5
source routing bridging specification[14] are 516,
1500, 2052, 4472, 8144, 11407, 17800, and 65535
octets. Behavior of the port when an illegal
value is written is implementation specific. It
is recommended that a reasonable legal value be
chosen.
