swPTPBoundaryPortAnnounceInterval
Module: PTP-MIB
OID (symbolic): PTP-MIB::swPTPBoundaryPortAnnounceInterval
OID (numeric): 1.3.6.1.4.1.171.12.94.1.2.2.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This indicates the mean time interval between successive announce messages.
In line with the IEEE1588 protocol, the value of the announce interval will be represented as the logarithm to base 2 of this time measured in seconds. The range is 1-16, so the import value must either be 1, 2, 4, 8, or 16. If the input is not allowed, then the input should be automatically adjusted to allow the biggest and closest value.
What is swPTPBoundaryPortAnnounceInterval?
A read-write value (1-16, auto-rounded to the nearest allowed power-of-two if an invalid value is entered) setting the mean interval, as log2 seconds per IEEE 1588, between Announce messages this boundary-clock port sends. Admins shorten this to make master-clock changes detected faster, at the cost of more Announce traffic on the link.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.94.1.2.2.1.1 snmpwalk -v2c -c public <target> PTP-MIB::swPTPBoundaryPortAnnounceInterval
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.94.1.2.2.1.1.1 snmpget -v2c -c public <target> PTP-MIB::swPTPBoundaryPortAnnounceInterval.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.171.12.94.1.2.2.1.1.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> swPTPBoundaryPortAnnounceInterval.1
