• If you configure sequence-number, the sequence-number is used as a tie breaker for rules with the sameorder.When you use the log option, the CP processor logs details about the packets that match. Depending on howmany packets match the log entry and at what rate, the CP may become busy as it has to log these packets’details.If you configure the sequence-number, the sequence-number is used as a tie breaker for rules with thesame order.NOTE: When you configure ACL logging and byte counters simultaneously, byte counters may displayan incorrect value. Configure packet counters with logging instead.Related Commands • deny — configure a filter to drop packets.• permit — configure a filter to forward packets.Extended IPv6 ACL CommandsThe following commands configure extended IPv6 ACLs.denyConfigure a filter that drops IPv6 packets that match the filter criteria.Syntax deny {ipv6-protocol-number | icmp | ipv6 | tcp | udp}To remove this filter, you have two choices:• Use the no seq sequence-number command syntax if you know the filter’s sequence number• Use the no deny {ipv6-protocol-number | icmp | ipv6 | tcp | udp} commandParameters ip-protocol-number Enter an IPv6 protocol number.
