usdHdlcIfMru
Module: Unisphere-Data-HDLC-MIB
OID (symbolic): Unisphere-Data-HDLC-MIB::usdHdlcIfMru
OID (numeric): 1.3.6.1.4.1.4874.2.2.9.1.2.1.5
Node type: OBJECT-TYPE
Type: Integer32
Access: read-create
Description: The Maximum Receive Unit (MRU) this interface is permitted to receive.
At creation, if a value for this object is not specified, a default will be chosen that is suitable for the type of lower interface on which this interface is stacked.
This setting plus 2 bytes for HDLC address/control plus the length in bytes of the HDLC CRC cannot exceed 65535. The maximum value for this object reflects the largest possible value when no CRC is used; technology constraints of a particular implementation may further limit the upper bound value.
What is usdHdlcIfMru?
This value sets the Maximum Receive Unit this HDLC interface is permitted to receive; combined with 2 bytes of HDLC address/control overhead plus the CRC length, the total cannot exceed 65535, and a suitable default is chosen automatically if left unspecified at creation. Admins tune it to ensure the interface can accept frames as large as the far end may send, avoiding drops of oversized received frames. Setting it to 1500 would configure the interface to accept frames up to a standard Ethernet-equivalent size.
