Configuration guidelines

When configuring an ACL, follow these guidelines:

Table 147 When defining rules in an ACL, you do not necessarily assign them numbers; the system can do this automatically. For more information, see ACL step.

Table 148 You cannot create a rule with, or modify a rule, to have the same permit/deny statement as an existing rule in the ACL.

Table 149 You can only modify the existing rules of an ACL that uses the match order of config. When modifying a rule of such an ACL, you may choose to change just some of the settings, in which case the other settings remain the same.
