Command

Purpose

•destination-object—(Optional) Contains the mandatory keyword dst and one of the following optional keywords:

–eq neq lt gt—Specifies equal to, not equal to, less than, or greater than. These keywords must be followed by the argument object-number, a numeric DECnet object number.

–exp—Stands for expression; followed by a regular expression that matches a string. See the “Regular Expressions” appendix in the Cisco IOS Dial Technologies Command Reference for a description of regular expressions.

–uic—Stands for user identification code; followed by a numeric UID expression. The argument [group, user] is a numeric UID expression. In this case, the bracket symbols are literal; they must be entered. The group and user parts can be specified either in decimal, in octal by prefixing the number with a 0, or in hex by prefixing the number with 0x. The uic expression displays as an octal number.
