Disruptive packet sniffing

Mon Nov 24, 2014 4:18 pm

Hi
I (remotely) enabled packet sniffing on an RB951G-2HnD and configured it to
transmit the collected packets to remote wireshark server.

I simply selected the interface and specified the direction (Tx)
and hit START....then POW !!! I lost access to my router

Luckily I had someone on site to disable the sniffing

I have run packet sniffing before in a similar manner, except that
I had specified PORT and DESTINATION IP in the filters

Is this a bug or did I do something silly ?

thanks
yann

You basically just duplicated all traffic being sent out of a given interface towards the wireshark server. Depending on where that is in relation to the network, you probably saturated your WAN interface for upload, thus cutting off your access.
