can I check NTP sync using SNMP ?

[Thijs Van Severen]

Hi all

Is it possible to check if a switch/router is properly synced to an NTP server using SNMP ?

via CLI it's easy by issuing the 'show ntp status' or 'show ntp associations', but can i somehow check this via SNMP ?

thanks !

Hi Thijs,

Try these:

Object     cntpSysSrvStatus OID     1.3.6.1.4.1.9.9.168.1.1.11

Hope it will help

Hi Afroz

thanks for your reply

however, if i try to get this OID i get this reply :

"iso.3.6.1.4.1.9.9.168.1.1.11 = No Such Object available on this agent at this OID"

a walk confirms that this OID doesnt exist (tried it on 2960, 3560, 4948, ASR)

do i need to enable something on the switch/router before i can access this OID ?

grtz

Hi Thijs,

It looks like the MIB is not supported on your device IOS.

Open the below link and click on "View Supported Images " to verify it.

try walking this OID: 1.3.6.1.2.1.197.1
Compare the output to 'sh ntp associations'

Hint: Hex-STRING: are your IPv4 and IPv6 addresses. There are websites where you can convert HEX to IP address if you don't want to figure out how. :)
