Usage Information seq c e s The monitor option is relevant in the context of the flow-based monitoring feature only. Refer to the Port Monitoring chapter. When you use the log option, CP processor logs details about the packets that match. Depending on how many packets match the log entry and at what rate, the CP may become busy as it has to log these packets' details. The order option is relevant in the context of the Policy QoS feature only. The following applies: • The seq sequence-number is applicable only in an ACL group. • The order option works across ACL groups that have been applied on an interface via QoS policy framework. • The order option takes precedence over the seq sequence-number. • If sequence-number is not configured, then rules with the same order value are ordered according to their configuration order. • If the sequence-number is configured, then the sequence-number is used as a tie breaker for rules with the same order. Note: When ACL logging and byte counters are configured simultaneously, byte counters may display an incorrect value. Configure packet counters with logging instead. You cannot include IP, TCP or UDP (Layer 3) filters in an ACL configured with ARP or Ether-type (Layer 2) filters. Apply Layer 2 filters to interfaces in Layer 2 mode. Assign a sequence number to a deny or permit filter in an extended IP access list while creating the filter. Syntax seq sequence-number {deny | permit} {ip-protocol-number | icmp | ip | tcp | udp} {source mask | any | host ip-address} {destination mask | any | host ip-address} [operator port [port]] [count [byte] | log] [dscp value] [order] [monitor] [fragments] Parameters sequence-number deny permit ip-protocol-number icmp Enter a number from 0 to 4294967290. S4810 and S4820T Range: 1 to 65534 Enter the keyword deny to configure a filter to drop packets meeting this condition. Enter the keyword permit to configure a filter to forward packets meeting this criteria. Enter a number from 0 to 255 to filter based on the protocol identified in the IP protocol header. Enter the keyword icmp to configure an ICMP access list filter. Access Control Lists (ACL) | 235
