Access: read-only
Description: This attribute provides the minimum delay independent from frame length for a frame to forward from ingress port to egress port.
The delay begins when the message timestamp point of the ingress frame passes the reference plane marking the boundary between the network media and PHY. The delay ends when the message timestamp point of the egress frame passes the reference plane marking the boundary between the network media and PHY. The message timestamp point is specified by IEEE Std 802.1AS for various media, near the start of the frame.
Note: This delay includes all aspects of length-independent delay for a frame that is forwarded, including handling of error conditions.
What is ieee8021TsnRemoteMgmtIndependentDelayMin?
This read-only value reports the minimum frame-length-independent forwarding delay for this bridge port, measured from the timestamp point as the frame crosses the media and PHY boundary on ingress to when it crosses that boundary again on egress. Network engineers configuring Time-Sensitive Networking (TSN) schedules use it as a lower bound on fixed forwarding latency, independent of packet size, needed to compute guaranteed delivery windows for time-critical traffic. For example, a TSN Central Network Controller reading ieee8021TsnRemoteMgmtIndependentDelayMin of 500 nanoseconds for a bridge port uses that value as the floor when calculating the tightest achievable end-to-end latency budget through that switch.
