xl VPN 3000 Concentrator Series User Guide
Data Formats
As you configure and manage the system, enter data in these formats unless the instructions indicate
otherwise.
IP addresses
IP addresses use 4-byte dotted decimal notation; for example, 192.168.12.34. You can omit leading
zeros in a byte position.
Subnet masks and wildcard masks
Subnet masks use 4-byte dotted decimal notation; for example, 255.255.255.0. Wildcard masks are
the reverse of subnet masks and use the same notation; for example, 0.0.0. 255. You can omit leading
zeros in a byte position.
MAC addresses
MAC addresses use 6-byte hexadecimal notation; for example, 00.10.5A.1F.4F.07.
Hostnames
Hostnames use legitimate network host or end-system name notation; for example, VPN01. Spaces are
not allowed. A hostname must uniquely identify a specific system on a network.
Tex t str ing s
Text strings use alphanumeric characters, upper- and lower-case. Most text strings are case-sensitive; for
example, simon and Simon represent different usernames. The maximum length of text stri ngs is
generally 48 characters.
Filenames
Filenames on the VPN Concentrator follow the DOS 8.3 naming convention: a m aximum of eight
characters for the name, plus a maximum of three characters for an extension. For example,
LOG00007.TXT is a legitimate filename. The VPN Concentrator always stores filenames as uppercase.
Port numbers
Port numbers use decimal numbers from 0 to 65535 with no commas or spaces.
