ieee8021AsPortStatTxPdelayResponseFollowUp

Module: IEEE8021-AS-MIB

OID (symbolic): IEEE8021-AS-MIB::ieee8021AsPortStatTxPdelayResponseFollowUp

OID (numeric): 1.3.111.2.802.1.1.20.1.6.1.15

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: A counter that increments every time a Pdelay_Resp_Follow_Up message is transmitted, denoted by a transition to TRUE from FALSE of the rcvdMDTimestampReceive variable of the MDPdelayResp state machine (see 11.2.16.1.2 and Figure 11-9) when in the SENT_PDELAY_RESP_WAITING_FOR_TIMESTAMP state, and resulting entry to the WAITING_FOR_PDELAY_REQ state.

What is ieee8021AsPortStatTxPdelayResponseFollowUp?

A counter of Pdelay_Resp_Follow_Up messages transmitted from this port, carrying the precise timestamp for a Pdelay_Resp just sent. Should track Tx Pdelay Response closely; a gap suggests this port's follow-up timestamping is failing.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.20.1.6.1.15
snmpwalk -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsPortStatTxPdelayResponseFollowUp

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.20.1.6.1.15.1
snmpget -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsPortStatTxPdelayResponseFollowUp.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ieee8021AsPortStatTxPdelayResponseFollowUp.1
