Here's a key to the markup: [page-number]: serious technical mistake {page-number}: minor technical mistake : important language/formatting problem (page-number): language change or minor formatting problem ?page-number?: reader question or request for clarification Confirmed errors: {425}, in the middle of the page is a description of the "mask" option of the "access-list rate-limit" command. replace the paragraph completely with the following text: ============= In the example above, access-list number 55 simply matches all packets with IP Precedence values of 5. You can also use a precedence bit mask to match several values in an 8-bit Precedence field that Cisco invented specially for this task. In this field, Precedence value 0 is represented by the binary number 00000001, 1 is represented as 00000010 and so forth up to IP Precedence value 7, which is 10000000. The mask is found by adding these binary values for each of the Precedence values you wish to include. For example, to match Precedence values 0, 1 and 2, you could use a mask of 00000111, which is 0x07 in hex. Router(config)#access-list rate-limit 56 mask 07 ============= Also, just about every instance of "access-list" in this recipe (11.12) is incorrectly written without the hyphen, as "access list". {489}The last sentence: "We have also included two watch lists, one for each of the watched IP addresses." should be changed to: "We have also included two dialer watch-list commands, one for each of the watched IP addresses."
