rxr1dSrPortLargestFrame
Module: IBM-RXR-MIB
OID (symbolic): IBM-RXR-MIB::rxr1dSrPortLargestFrame
OID (numeric): 1.3.6.1.4.1.2.6.26.1.3.1.1.6
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
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. 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.
What is rxr1dSrPortLargestFrame?
Sets the largest INFO-field frame size this source-route bridging port can send or receive, from 516 up to 65535 octets per the 802.5 source-routing spec, which the bridge uses to correctly populate the LargestFrame field of the Routing Information Field in explorer frames. An admin sets this to match the actual MTU capability of the attached ring segment to avoid frames being needlessly fragmented or rejected.
