TP-LINK Switches: Network Interfaces

Distribution: official part of Check_MK
License: GPL
Supported Agents: SNMP

This check is almost identical to if64. It additionally uses the OID . to obtain meaningful interfaces aliases and only uses ifAlias as a fallback. Please refer to if64 for the complete manual page.


There are three allowed ways to specify an interface: its index ifIndex, its description ifDescr and its alias, which is fetched from the OID mentioned above if available. Otherwise, ifAlias is used as a fallback.


One service is created for each interface that fulfills configurable conditions (rule "Network interface and switch port discovery"). By default, these are interfaces which are currently found up and are of type 6, 32, 62, 117, 127, 128, 129, 180, 181, 182, 205 or 229.

Grouping: In some situations, you do not want to monitor a single interface but a group of interfaces that together form a pool. This check supports such pools by defining groups. The data of all members is accumulated and put together in a single grouped interface service.
