Version 8.1.1.0 Version 7.6.1.0 Version 7.5.1.0 Version 7.4.1.0 Version 6.5.10 Introduced on E-Series ExaScale Support added for S-Series Support added for C-Series Added support for non-contiguous mask and added the monitor option. Expanded to include the optional QoS order priority for the ACL entry. Usage The order option is relevant in the context of the Policy QoS feature only. See the "Quality of Information Service" chapter of the FTOS Configuration Guide for more information. 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 C-Series and S-Series cannot count both packets and bytes, so when you enter the count byte options, only bytes are incremented. The monitor option is relevant in the context of flow-based monitoring only. See the Chapter 45, Port Monitoring. Note: When ACL logging and byte counters are configured simultaneously, byte counters may display an incorrect value. Configure packet counters with logging instead. Related Commands ip access-list extended permit tcp permit udp Create an extended ACL. Assign a permit filter for TCP packets. Assign a permit filter for UDP packets. permit arp e Configure a filter that forwards ARP packets meeting this criteria.This command is supported only on 12-port GE line cards with SFP optics; refer to your line card documentation for specifications. Syntax permit arp {destination-mac-address mac-address-mask | any} vlan vlan-id {ip-address | any | opcode code-number} [count [byte] | log] [order] [monitor] [fragments] To remove this filter, use one of the following: • Use the no seq sequence-number command syntax if you know the filter's sequence number or • Use the no permit arp {destination-mac-address mac-address-mask | any} vlan vlan-id {ip-address | any | opcode code-number} command. Parameters destination-mac-address mac-address-mask any Enter a MAC address and mask in the nn:nn:nn:nn:nn format. For the MAC address mask, specify which bits in the MAC address must match. The MAC ACL supports an inverse mask, therefore, a mask of ff:ff:ff:ff:ff:ff allows entries that do not match and a mask of 00:00:00:00:00:00 only allows entries that match exactly. Enter the keyword any to match and drop any ARP traffic on the interface. Access Control Lists (ACL) | 227
