TP-LINK Switches: Network Interfaces

Distribution: check_mk
License: GPL
Supported Agents: SNMP

This check is a copy if if64 but fixes two bugs of TP-LINK in their MIB implementation that lead to wrong interface speed and wrong alias names of ports. Both issues have been worked around in this check plugin. Please refer to if64 for the complete manual page.


There are three allowed ways to specify a port: 1: the last component of the SNMP OID number (as string), the ifDescr of the port or the ifAlias of the port. If you are using the alias, you have to make sure that it is unique by configuring useful aliases in the switch. Checkmk does not check for uniqueness.


One service is created for each port that fulfills configurable conditions. Per default these are ports which are currently found up and are of types 6 (ethernetCsmacd), 32 (frameRelay), 117 (gigabitEthernet) or several others.

For further details look at if64 manpage.
