ieee8021AsPortDSAnnounceReceiptTimeout
Module: IEEE8021-AS-MIB
OID (symbolic): IEEE8021-AS-MIB::ieee8021AsPortDSAnnounceReceiptTimeout
OID (numeric): 1.3.111.2.802.1.1.20.1.5.1.21
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: The value is the number of Announce message transmission intervals that a slave port waits without receiving an Announce message, before assuming that the master is no longer transmitting Announce messages, and that the BMC algorithm needs to be run, if appropriate. The condition of the slave port not receiving an Announce message for announceReceiptTimeout announce intervals is referred to as 'announce receipt timeout'.
The default value is 3 (see 10.6.3.2).
The contents of this variable SHALL be maintained across a restart of the system.
What is ieee8021AsPortDSAnnounceReceiptTimeout?
How many Announce-message intervals a slave port waits without hearing from its master before declaring an announce receipt timeout and re-running the best master clock algorithm. Shortening it makes the port fail over to a new master faster after losing its current one, at the cost of being more sensitive to brief packet loss.
