follows to the list of rules that are associated with access profile 1. For each
rule entered into the access profile, you can assign an access_id that both
identifies the rule and establishes a priority within the list of rules. A lower
access_id gives the rule a higher priority. In case of a conflict in the rules
entered for an access profile, the rule with the highest priority (lowest
access_id) will take precedence.
The ip parameter instructs the Switch that this new rule will be applied to the
IP addresses contained within each frame’s header. source_ip tells the Switch
that this rule will apply to the source IP addresses in each frame’s header.
Finally, the IP address 10.42.73.1 will be combined with the source_ip_mask
255.255.255.0 to give the IP address 10.42.73.0 for any source IP address
between 10.42.73.0 to 10.42.73.255.
