detail—Shows detailed information for the specified DHCP bindings
filter—See Filtering show Commands on page 4
string—Regular expression string that represents the interface, circuit ID, or remote ID
to be matched; you must enclose elements containing a space within double quotes
("one element")
Each element is either a literal string, a metacharacter, or a combination. You can
remove the special meaning of a metacharacter by preceding it with a backslash (\).
Regular expressions support the following metacharacters:
^ Matches the beginning of the input string. Alternatively, when used as the first
character within brackets—[^ ]—matches any number except the ones specified
within the brackets.
$ Matches the end of the input string
. (period) Matches any single character, including white space
* Matches 0 or more sequences of the immediately previous character or pattern.
+ Matches 1 or more sequences of the immediately previous character or pattern
? Matches 0 or 1 sequence of the immediately previous character or pattern
( ) Specifies patterns for multiple use when followed by one of the multiplier
metacharacters: asterisk *, plus sign +, or question mark ?
[ ] Matches any enclosed character; specifies a range of single characters
– (hyphen) Used within brackets to specify a range of AS or community numbers
_ (underscore) Matches a ^, a $, a comma, a space, a {, or a }. Placed on either side
of a string to specify a literal and disallow substring matching. Numerals enclosed
by underscores can be preceded or followed by any of the characters listed above
| Matches characters on either side of the metacharacter; logical OR
You must specify the interface string as a regular expression without spaces; for
example, fastEthernet1.1/100 or fastEthernet.*100
The following rules apply for representing nonprintable character sequences in the
circuit ID string or the remote ID string:
To represent the binary sequence 0d 0a (hex), use the string '\\r\\n'. This consists
of four ASCII characters: 5c for \\, 72 for r, 5c for \\, and 6e for n.
For example, to match the sequence 74 65 73 74 0d 0a 6f 6e 65 (hex), use the string
'test\\r\\none'. In this string, 74 is represented by t, 65 is represented by e, 73 is
represented by s, 74 is represented by t, 0d 0a is represented by \\r\\n, 6f is
represented by o, 6e is represented by n, and 65 is represented by e.
To represent the binary sequence 0d 00 (hex), use the string '\\r'. This consists of
two ASCII characters: 5c for \\, and 72 for r.
