-- It would be nice if we could use ifMtu as the size of the -- largest frame, but we can't because ifMtu is defined to be -- the size that the (inter-)network layer can use which can -- differ from the MAC layer (especially if several layers of -- encapsulation are used).
dot1dSrPortLargestFrame OBJECT-TYPE SYNTAX INTEGER ACCESS read-write STATUS mandatory DESCRIPTION "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.

An illegal value will not be accepted by the bridge." ::= { dot1dSrPortEntry 6 }
dot1dSrPortSTESpanMode OBJECT-TYPE SYNTAX INTEGER { auto-span(1), disabled(2), forced(3) } ACCESS read-write
STATUS mandatory DESCRIPTION "Determines how this port behaves when presented with a Spanning Tree Explorer frame. The value 'disabled(2)' indicates that the port will not accept or send Spanning Tree Explorer packets; any STE packets received will be silently discarded. The value 'forced(3)' indicates the port will always accept and propagate Spanning Tree Explorer frames. This allows a manually configured Spanning Tree for this class of packet to be configured. Note that unlike transparent bridging, this is not catastrophic to the network if there are loops. The value 'auto-span(1)' can only be returned by a bridge that both implements the Spanning Tree Protocol and has use of the protocol enabled on this port. The behavior of the port for Spanning Tree Explorer frames is determined by the state of dot1dStpPortState. If the port is in the 'forwarding' state, the frame will be accepted or propagated. Otherwise, it will be silently discarded." ::= { dot1dSrPortEntry 7 }
