Chapter 2
Command Line Interface
This chapter introduces the Command Line Interface (CLI) hierarchy and the conventions used to describe it. It
also introduces the CLI navigation keys and methods, as well as the available help screens.
Command Types
This guide contains two types of commands: transition, or mode change, commands and standard commands.
Transition commands do not affect the syst em configuration, they are used to ga in access to lower- or next-level
commands in the CLI hierarchy. Following each transition command is a brief description, a syntax and usage
example, a list of next-level commands, and a list of systems for which the command is applicable.
NOTE: In certain instances, transition commands will select an interface for configuration and access next-level
commands. For example, the configure interface bundle dallas command accesses the configure interface
bundle mode and selects or creates the bundle dallas.
Stan da rd comma nds a re u sed t o conf igure t he syst em. Fo llowing ea ch st and ard co mman d is a brie f desc ript ion, a
list of parameters and definitions, a syntax and usage example, a list of related commands, and a list of systems
for which the command is applicable.
Context-Sensitive Commands
Some commands are context-sensitive. Once a module, bundle, or Ethernet port has been selected for
configuration, all further configuration applies only to the selected interface. Table 2.1: shows a context-sensitive
command string for a AR1208 system. In this example, T1 link 1 remains selected for configuration until you exit
from the Foundry-AR1208/con fig ure / mo dul e/t1 # prom pt.
Table 2.1: Context-Sensitive Command Sequence
Context-Sensitive Command String Example
1 Go into the configuration mode.
1 Specify the type of interface (T1). Foundry-AR1208/configure#module t1
Foundry-AR1208#configure terminal
1 Choose the specific interface (T1 link 1). Foundry-AR1208/configure#module t1 1
1 From now on, al l con figurat ion co mman ds
are for T1 link 1 until y ou exi t from mo dule
configuration or choose another T1 link.

Foundry AR-Series Router User Guide
NOTE: Command strings that require identification of a specific interface are context-sensitive.
Command Conventions
Each command is briefly described and then followed by the complete syntax, which is essentially a map of the
command that shows mandatory and optional parameters.
The following tables provide details of the conventions used for syntaxes and examples.
Table 2.2: Syntax Conventions
For Syntaxes What it means
normal type Within syntaxes, “normal type” represents required words
that must be entered by the user — except when follo wed by
a parameter setting that is enclosed in angled brackets. In
that case, only enter the parameter setting enclosed in the
angled brackets .
Example 1: Normal type only.
In this example, the user enters the word or argument
(module) appearing in the syntax in “normal type.”
Syntax:
module
Command execution:
module
Example 2: Normal type word or argument that is followed
by a second normal type word or argument, which is
followed by a p aram eter setting enclose d i n a ngl ed bra ck et s .
In this example, the user enters the first word or argument
“connections,” appearing in normal type, and then only
enters the value “4” of the second word or argument.
Syntax:
connections connections < n >
Command execution:
connections 4
In other words, the first occurence of “connections” must be
entered because it is not followed by a setting enclosed in
angled brackets. The second occurence of the word
“connections” must NOT be entered bec au se it is followed
by a setting enclosed in angled brackets. This value of the
setting must be entered to execute the command.

Command Line Interface
Table 2.2: Syntax Conventions (Continued)
[ a | b | c ] Normal brackets “[ ]” indicate optional keywords or
arguments.
A vertical bar “ | “ separates individual settings.
Example:
In this example, the user enters the word “timeout;” must
specify either for “tcp” or “udp” for a protocol type; and
optionally enters a timeout value “n.”
Syntax:
timeout protocol_ty pe < tcp | udp > [ s econds < n > ]
Command execution:
timeout udp 3600
< # Angled brackets. All parameter settings are enclosed in
angled brackets. The user is directed to choose an
appropriate setting. In some cases, the parameter name
accompanies the required setting.
[ ] Optional parameter settings in each syntax are indicated by
normal brackets.
Table 2.3: Example Conventions
For Examples What it means
normal type Prompts and comman ds that are p art of th e main prompt a re
shown in normal type.
Examples:
Foundry-AR1208#
Foundry-AR1208/show#
bold type All character strings that a user must enter to execute a
command are in bold type.
Example:
Foundry-AR1208# configure term
Abbreviated Commands
You may enter commands by typing the first few characters of each word in a command string. The Foundry
system recognizes the unique abbreviated entry and executes the command exactly as if you had entered it fully.
For example, to view the currently running system configuration, you may type show configuration running at
the Foundry# prompt. You may also type dis con run to get the same result. Similarly, you may abbreviate the
optional parameter names required by some commands.
For example, a typical entry may be as follows:
mlppp mrru 1600 sequence short seg_threshold 1000 differential_delay 100 discriminator 10.1.100.22
To save time, you may type the following equivalent abbreviated string:
mlppp m 1600 seq short seg 1000 diff 100 dis 10.1.100.22

CLI Navigation
The Tab, Esc, and Ctrl keyboard keys may be used to:
• Move backwards or forwards in the CLI
• Edit entered command strings
• Or acceler ate the command entry process
Navigation Keys
You may use the Tab key to quickly enter each word of a command without typing its full name. For example, to
enter the configure command, you may type its first two letters and then press Tab to complete the entire word.
Then, you may specify an item to configure by pressing the Spacebar and then pressing Tab repeatedly until the
desired sub-command appears. Repeat this sequence for each successive sub-command string until the entire
command string appears.
You may also use the other keystrokes shown in during command entry. For example, to back up the cursor
without deleting any charac ters, type Ctrl-B. To repeat the last command that yo u entered , type Ctrl-P. T o go back
several commands, type Ctrl-P repeatedly until the desired previous command appears. Or, you may go directly
back to the main CLI# prompt from anywhere in the command hierarchy by typing Ctrl-Z.
Figure 2.1 Navigation Keys
# help edit

configure policy as_path
This command configures the autonomous system path filter for BGP.
AS path access li sts are used for matching the AS path attribute in a BGP route. An AS path access lis t s ucce eds
if any “permit” line in the list m atches, o r fails if a ny “deny” l ine matc hes. Matchin g proceed s sequen tially an d stops
at the first match.
The regular expressio n p a ram ete r is an a s path regular expression. (For regular expressio n syntax, see “AS Path
Regular Expressions” on page 13-1.) Note that the regular expression must be enclosed in quotation marks. The
AS number is the smallest element of a Foundry regular expression. It is an integer ranging from 0 to 65536; the
Foundry regular expression matcher is AS number-based.
Any number of AS path access list lines may be declared. They are evaluated in the order declared. If neither
permit nor deny is specified, the default is “permit.”
Parameter Description
access_list Access list number
Range is 1 - 199.
number Sequence to insert or delete from an existing AS path entry.
Range is 0 - 65535.
action
deny Deny AS path.
permit Permit AS path.
regular_expression Regular expression to match the AS paths.
Enter a quot ed string.
Refer to “AS Path Regular Expressions” on page 13-1 for more
information about regular expressions.

Policy Commands
configure policy community_list
This command accesses next-level commands for adding extended or standard community lists.
Community list s are used for m atchin g the “com muni ty” attrib ute in a BGP rou te. A comm unity list su cceed s if any
“permit” line in the list matches, or fails if any “deny” line matches. Matching proceeds sequentially and stops at
the first match. A line in a community list is normally said to match if the route being tested contains at least all of
the communities listed in the line. That is, it may contain additional communities as well. If the exact-match
keyword is used, then it must contai8n exactly the same communities as listed.
The communities pa rameter can be:
• local_as
• no_advertise
• no_export
• aa:nn (an integer between 0 and 65,535)
• community (an integer between 1 and 4294967295
Note that “exact_m atc h” is su ppo rted in the community_list as well as at the route_map lev el. If n ei ther permit nor
deny is specified, the default is pe rmi t. If n o community is specified, any route w il l b e ma tch ed, regardless of what
communities are present. The route will even be matched if the community path attribute is not present. Any
number of community list lines may be declared. They are evaluated in the order declared.

configure policy ip_access_list
This command configures the IP access list for routes.
Ip access lists are used for matching any type of route prefix. An IP access list is said to succeed if any “permit”
line in the list matc hes, or fails, if any “deny” line matches. Matching proceeds sequentially and stops at the first
match. A line in an IP access list is said to match according to the rules listed below.
• network netmask
Matches addresses as fo llow s: The bi t s in t he add ress p art of the ro ute be ing ma sked that ar e not c overed by
“one” bits in net mask must be equal to the corresponding bits in network. The “one” bits in net mask are
sometimes referred to as “don’t care” bits, because the policy engine does not care what their values are.
• network netmask mask maskmask
Matches addresses as follows: The first pair of parameters (network, maskmask) match the address part of
the route just as in the previous (network netmask) form. The second pair of parameters (mask, maskmask)
are used to match against the mask part of the route being matched in a similar fashion. That is, the route is
matched if the address part matches and the bits in the mask that are not covered by “one” bits in net mask
are equal to the corresponding bits in mask.
If neither permit nor deny is specified, the default is permit. All kinds of access_list entries may be mixed freely
within a list, and there are no restrictions on what the access_list number may be. Any number of IP access list
lines may be declared. They are evaluated in the order declared.
Parameter Description
access_list Access list number
The range is 1 - 99
number Sequence to insert to or delete from an existing access list entry.
The range is 0 - 65535.
action
deny Route map deny set operation.
permit Route map permit set operation.
network Network route (IP address in dotted notation)
netmask Network mask as wildcard bits (IP address in dotted notation)
mask Network route’s mask (IP address in dotted notation)
maskmask Wildcard mask for network route’s mask ( in dotted notation)
syntax:
[ no ] policy ip_access_list access_list < n > number < n > action < deny | permit > [ network < IP address > ] [
netmask < IP address > ] [ mask < IP address > ] [ maskmask < IP address > ]
example:
Foundry-AR1208/configure# policy ip_access_list 1 1 permit network 10.0.0.0 netmask 0.255.255.255
This example permits prefixes 10.0.0.0/8, 10.0.0.0/9 and so on.
