Command Syntax Conventions

Description
{ keyword or variable }

Required keyword options and variables are those components that are required to be entered as part of the command syntax.

Required keyword options and variables are surrounded by grouped braces { }. For example: 

sctp-max-data-chunks { limit max_chunks | mtu-limit }

If a keyword or variable is not enclosed in braces or brackets, it is mandatory. For example:

snmp trap link-status
[ keyword or variable ]

Optional keywords or variables, or those that a user may or may not choose to use, are surrounded by brackets.

|

Some commands support multiple options. These are documented within braces or brackets by separating each option with a vertical bar.

These options can be used in conjunction with required or optional keywords or variables. For example:

action activate-flow-detection { intitiation | termination }
or
ip address [ count number_of_packets | size number_of_bytes ]
