ntpCommonTTL
Module: SYMMNTP
OID (symbolic): SYMMNTP::ntpCommonTTL
OID (numeric): 1.3.6.1.4.1.9070.1.2.5.1.2.2.1.1.3
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: IP header time-to-live (TTL) field for the NTP packets. Range is 1-255. Default value is 64.
What is ntpCommonTTL?
This read-write object configures the IP TTL value placed in the header of NTP packets sent from this port, defaulting to 64. Admins might lower it in specific network scenarios to limit how far NTP packets can propagate, though most deployments would leave it at the default. Setting ntpCommonTTL to 32 would limit the NTP packets from this port to a smaller hop-count radius before being dropped by intermediate routers.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9070.1.2.5.1.2.2.1.1.3 snmpwalk -v2c -c public <target> SYMMNTP::ntpCommonTTL
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9070.1.2.5.1.2.2.1.1.3.1 snmpget -v2c -c public <target> SYMMNTP::ntpCommonTTL.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.9070.1.2.5.1.2.2.1.1.3.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ntpCommonTTL.1
