Control an interface using snmp

Votes:

0

Is it possible to control an interface (I.E. disable it) if the interface receives too much data in one go? I.E. typical data stream (multicast data) is 10Kbps - but if it exceeds that, I want the interface to disable immediately.

Hi,

Using limits, you can trigger a notification when a treshold exceeds. See also the Paessler website: How to set up notifications via the PRTG web interface.

The notification can be a .exe like snmptrapgen. SnmpTrapGen is a command-line tool allowing you to send SNMP traps to a device.

Hi,

you could do it via notifications. As a notification you can run a script for example which will use snmp or ssh to disable the interface. But you would somehow need to reference the interface somehow, so I think this is not a really good solution.

If you want to control just broadcast/multicast traffic, many switches/routers support a rate-limiting feature which can be used for those traffic types. This also has the advantage, that you still can use the regular unicast traffic..
