Port Blocking with allowable traffic from authorized ip address blocks

In running rmon2 and proprietary probes, recently, I began to receive flood traffic on the probe specific ports. I tried std acl port blocking but now I need to allow that specific port from specific ip blocks as authorized traffic while blocking all other ip v4 addresses.

You can achieve this by configuring the extendend access lists and block the unwanted traffic and allow traffic only from the authorised IP address range. The commands for the same are explained in this document: Extended ACLs
