BASIC SETUP

An SNMP agent is running on each CENTAURI device. To query the SNMP agent for any given device, you may use either the MIB OID or numerical OID.

Example using MIB OID:

snmpget -On -t 10 -v 1 -c community <hostname|IP> TCT-SNMP-MIB::tctSnmpRxPwr

Example using numerical OID:

snmpget -On -t 10 -v 1 -c community <hostname|IP> .1.3.6.1.4.1.54505.1.1

To obtain the numerical OID from the MIB OID you must first add the TCT-SNMP-MIB.txt file to your SNMPD MIBs directory. This is done by adding the TCT-SNMP-MIB.txt file with the following contents to .snmp/mibs (or to whatever directory is used to store your MIBs).

snmptranslate -On TCT-SNMP-MIB::tctSnmpRxPwr

USING DIFFERENT VERSIONS OF SNMP

While we strongly recommend that you use SNMP v3, we do support SNMP v1 and SNMP v2. Note that the query commands used to poll for telemetry are different depending on which version of SNMP is being applied.

SNMP v1

snmpget - On - t 10 -v l -c community <hostname|IP> .1.3.5.1.4.1.54505

SNMP v2

snmpget - On - t 10 -v 2c -c community <hostname|IP> .1.3.6.1.4.1.54505.1.1

SNMP v3 *

snmpget - On - t 10 -v 3 -l authPriv -u **** -a sha -A **** -x aes -X **** <hostname|IP> .1.3.6.1.4.1.54505.1.1

* You will need to obtain a username, password, and passphrase from Transcelestial when setting up your SNMP client.

USING SNMP PROXY

Transcelestial supports SNMP proxy, which may be useful when setting up monitoring for a fleet of CENTAURI devices. To learn more about using SNMP proxy for CENTAURI, see this article. You may also contact us for more information.

[NEW] GET THE LATEST MIB FILE

The most up-to-date MIB file for SNMP is attached as a link to this article. If you have any questions or need assistance in configuring and implementing SNMP for your organisation please contact us.

Please refer to this table to understand which MIB file to use for different software versions. If a software version is not included in the table, refer to the latest lower version, e.g. for v5.15.0, use the MIB file corresponding to v5.8.0.
