usdL2tpTunnelStatusSendSeqAck

Module: Unisphere-Data-L2TP-MIB

OID (symbolic): Unisphere-Data-L2TP-MIB::usdL2tpTunnelStatusSendSeqAck

OID (numeric): 1.3.6.1.4.1.4874.2.2.35.1.3.2.1.1.20

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: The send sequence number that the tunnel peer has acknowledged. The flow control state can be determined by subtracting the usdL2tpTunnelStatusSendSeq from usdL2tpTunnelStatusSendSeqAck and comparing this value to usdL2tpTunnelStatusSendWindowSize.

What is usdL2tpTunnelStatusSendSeqAck?

The highest send sequence number the peer has acknowledged; subtracting Send Seq from this and comparing to Send Window Size shows how much control-flow headroom remains.
