prConPortIFM
Module: A3COM0054-BRASICA2-SPECIFIC
OID (symbolic): A3COM0054-BRASICA2-SPECIFIC::prConPortIFM
OID (numeric): 1.3.6.1.4.1.43.10.34.2.1.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object controls Intelligent Flow Management for the port, which specifies what action the port takes whenever it is unable to receive a packet because its buffers are full. When set to off(1), the packet is dropped immediately. If it is set to any of the values maxJams6(2) to maxJams13(10), a jam signal is transmitted to the segment attached to the port to force a collision so that the originator will stop and retransmit the frame. This will be repeated a maximum of 6 to 13 times depending on the setting. If the port is then still unable to receive the packet it is dropped. Intelligent Flow Management should be disabled on ports which are connected to repeater segments.
Intelligent flow management only functions when a port is operating in half duplex, either as a result of auto-negotiation, or by management action.
What is prConPortIFM?
This INTEGER setting configures Intelligent Flow Management, controlling how a port handles buffer overflow—drop frames immediately or send jam signals to trigger retransmits. Engineers tune IFM to manage congestion; jam signals reduce loss at the cost of network collisions. Setting it to 'maxJams6' enables collision signaling up to 6 times before dropping frames, protecting against data loss.
