When using the ip access-list standard command to create the IP standard ACL, the ACL can be created only after configuring the rules in the IP standard ACL configuration mode.
- Sequence means the order number of the rule in the ACL. ACL matches and filters the packet strictly according to the order from small sequence to large sequence. The rule with the small sequence first takes effect. When all rules do not match, execute the default drop action, that is, all the packets not permitted to pass are dropped.
Configure IP Standard ACL Named by Numbers
The IP standard ACL named by numbers can let the user identify the type of the ACL quickly. However, the IP standard ACL named by numbers has some limitations. For example, the ACL quantity is limited.
