The ArubaOS-CX switch configuration includes an access list named 'external' that permits traffic from any IP to the subnet 10.0.253.0/24 and applies a count action, and also permits traffic from any IP to the subnet 10.0.254.0/24 and applies a log action. This configuration is applied to interface 1/1/1 for incoming traffic. Therefore, traffic from any source to 10.0.253.0/24 will increment the counters due to the 'count' action specified.
