_ (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.
To represent the binary sequence 0a 00 (hex), use the string '\\n'. This
consists of two ASCII characters: 5c for \\, and 6e for n.
For example, to match the sequence 74 65 73 74 0a 00 6f 6e 65 (hex), use
the string 'test\\none'. In this string, 74 is represented by t, 65 is represented
by e, 73 is represented by s, 74 is represented by t, 0a 00 is represented by
\\n, 0a is represented by \\n, 6f is represented by o, 6e is represented by n,
and 65 is represented by e.
To represent all other cases, use the string '\\xab', where ab is a hex code
of the byte. For example, to represent byte 3A, use '\\x3a'. This consists of
four ASCII characters: 5c for \\, 78 for x, 33 for 3, and 61 for a.
As another example, to match the sequence 74 65 73 74 f3 6f 6e 65 (hex),
use the string 'test\\xf3one'. In this string, 74 is represented by t, 65 is
represented by e, 73 is represented by s, 74 is represented by t, byte F3 is
represented by \\xf3, 6f is represented by o, 6e is represented by n, and 65
is represented by e.
