ip access-list filter
Use this command to configure access control entry in an access control list (ACL).
This determines whether to accept or drop an IP packet based on the configured match criteria.
Use the no form of this command to remove an ACL specification. ACL specification can be removed using the sequence number as well.
Note: Configuring same filter again with change of sequence number or change of action will result in update of sequence number or filter action.
