www.dell.com | support.dell.com mac-source-address-mask mac-destination-address mac-destination-address-mask ethertype operator count byte log monitor Specify which bits in the MAC address must be matched. 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 destination MAC address and mask in nn:nn:nn:nn:nn:nn format. Specify which bits in the MAC address must be matched. 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. (OPTIONAL) To filter based on protocol type, enter one of the following Ethertypes: • ev2 - is the Ethernet II frame format. • llc - is the IEEE 802.3 frame format. • snap - is the IEEE 802.3 SNAP frame format. (OPTIONAL) Enter the keyword count to count packets processed by the filter. (OPTIONAL) Enter the keyword byte to count bytes processed by the filter. (OPTIONAL, E-Series only) Enter the keyword log to log the packets. (OPTIONAL) Enter the keyword monitor when the rule is describing the traffic that you want to monitor and the ACL in which you are creating the rule will be applied to the monitored interface. For details, see the section "Flow-based Monitoring" in the Port Monitoring chapter of the FTOS Configuration Guide. Defaults Not configured. Command Modes CONFIGURATION-MAC ACCESS LIST-EXTENDED Command History Version 8.3.5.0 Version 8.1.1.0 Version 7.6.1.0 Version 7.5.1.0 Version 7.4.1.0 pre-Version 6.1.1.0 Introduced on the S55. Introduced on E-Series ExaScale Support added for S-Series Support added for C-Series Added monitor option Introduced for E-Series Note: When ACL logging and byte counters are configured simultaneously, byte counters may display an incorrect value. Configure packet counters with logging instead. Usage Information Related Commands 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. deny Configure a filter to drop traffic based on the MAC address. seq Configure a filter with specific sequence numbers. 230 | Access Control Lists (ACL)
