rsHdlcIfMtu
Module: REDSTONE-HDLC-MIB
OID (symbolic): REDSTONE-HDLC-MIB::rsHdlcIfMtu
OID (numeric): 1.3.6.1.4.1.2773.2.9.1.2.1.4
Node type: OBJECT-TYPE
Type: Integer32
Access: read-create
Description: The Maximum Transmission Unit this interface is permitted to transmit.
At creation, if a value for this object is not specified, a suitable default will be chosen 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 rsHdlcIfMtu?
This Integer32 value (0-65533 octets) specifies the Maximum Transmission Unit the HDLC interface is permitted to transmit. Admins adjust this to control the largest frame size sent on the link, keeping in mind that this value plus 2 bytes of HDLC address/control plus the CRC length cannot exceed 65535 octets total. For example, setting rsHdlcIfMtu to 1500 matches a typical Ethernet-style payload size for traffic carried over the HDLC-framed link.
