Defining Profile Rules
Access profiles can contain up to 128 rules to determine who is permitted to
manage and access the switch, and the access methods that may be used.
Each rule in an access profile contains an action and criteria (one or more
parameters) to match. Each rule has a priority; rules with the lowest priority are
checked first. If the incoming packet matches a rule, the action associated with the
rule is performed. If no matching rule is found within the active access profile, the
packet is dropped.
For example, you can limit access to the switch from all IP addresses except IP
addresses that are allocated to the IT management center. In this way, the switch
can still be managed and has gained another layer of security.

a first-fit basis.
