Dell Force10 Z9000 FTOS Configuration Guide for Z9000 System - Page 98

www.dell.com | support.dell.com If you are creating a standard ACL with only one or two filters, you can let FTOS assign a sequence number based on the order in which the filters are configured. The software assigns filters in multiples of 5. To configure a filter without a specified sequence number, use these commands in the following sequence, starting in the CONFIGURATION mode: Step Command Syntax 1 ip access-list standard access-list-name 2 {deny | permit} {source [mask] | any | host ip-address} [count [byte] | log] [order] [monitor] [fragments] Command Mode CONFIGURATION CONFIG-STD-NACL Purpose Create a standard IP ACL and assign it a unique name. Configure a drop or forward IP ACL filter. • log and monitor options are supported on E-Series only. When you use the log keyword, 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. Figure 6-5 illustrates a standard IP ACL in which the sequence numbers were assigned by the FTOS. The filters were assigned sequence numbers based on the order in which they were configured (for example, the first filter was given the lowest sequence number). The show config command in the IP ACCESS LIST mode displays the two filters with the sequence numbers 5 and 10. Figure 6-5.
