meaning integer 26 in SNMP

I'm starting with SNMP with SNMPwalk ... And I always find that next to the OIDs ' Integer = 26 ' appears.

What does it mean?

Example Code:

.1.3.6.1.2.1.17.4.3.1.2.200.203.184.30.98.3 = INTEGER: 26
.1.3.6.1.2.1.17.4.3.1.2.200.203.184.32.34.183 = INTEGER: 26
.1.3.6.1.2.1.17.4.3.1.2.200.211.255.17.129.22 = INTEGER: 26

OR

.1.3.6.1.2.1.17.7.1.2.2.1.3.11.20.167.139.159.35.83 = INTEGER: 3
.1.3.6.1.2.1.17.7.1.2.2.1.3.11.20.167.139.159.35.160 = INTEGER: 3
.1.3.6.1.2.1.17.7.1.2.2.1.3.11.36.94.190.4.46.254 = INTEGER: 3

Thanks for the support.

Solution

  • .1.3.6.1.2.1.17.4.3.1.2 points to a column dot1dTpFdbPort in dot1dTpFdbTable.

    You need a MIB browser so as to visually analyze the table with more details.

    The postfix like .200.203.184.30.98.3 is the actual index dot1dTpFdbAddress (which is a MAC address).

    The value of 26 refers to port 26 of this device, if you read the description of dot1dTpFdbPort

    The other group of objects are similar.

    You cannot learn SNMP without reading the MIB documents.
