Control an interface using snmp

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.

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..
