Command Syntax Conventions
Note on ACL ACLs can enhance network security by blocking selected IP traffic, and can
Security Use
serve as one aspect of maintaining network security. However, because ACLs
do not provide user or device authentication, or protection from malicious
manipulation of data carried in IP packet transmissions, they should not
be relied upon for a complete security solution.
For information on how to apply ACLs in a network populated with HP
ProCurve switches that support the ACL feature, refer to the chapter titled
“Access Control Lists (ACLs)” in the Advanced Traffic Management Guide
for your switch.
Command Syntax Conventions
This guide uses the following conventions for command syntax and displays.
Syntax: ip < default-gateway < ip-addr >> | routing >
Syntax: show interfaces [ port-list ]
■ Vertical bars ( | ) separate alternative, mutually exclusive elements.
■ Square brackets ( [ ] ) indicate optional elements.
■ Braces ( < > ) enclose required elements.
■ Braces within square brackets ( [ < > ] ) indicate a required element within
an optional choice.
■ Boldface indicates use of a CLI command, part of a CLI command syntax,
or other displayed element in general text. For example:
“Use the copy tftp command to download the key from a TFTP server.”
■ Italics indicate variables for which you must supply a value when execut-
ing the command. For example, in this command syntax, you must provide
one or more port numbers:
Syntax: aaa port-access authenticator < port-list >
