hi guys, the below is from Websense support:
A WISP is = websense integration server protocol, it is a request for filtering service to determine if a blockpage should be enforced on that URL request by the user.
The only thing you need to do is make sure the port that is mirrored/span is configured bidirectional as well, so the blocking nic can send a block if it is needed.
I have set up the mirroring port and it is monitoring it, but cannot seem to block it. I was told to see if this is compatible with Meraki. Thanks.
