Management port overview

The management port is an out-of-band port that customers can use to manage their devices without interfering with the in-band ports. The management port is widely used to download images and configurations and for Telnet sessions.

How the management port works

The following rules apply to management ports:

•Only packets that are specifically addressed to the management port MAC address or the broadcast MAC address are processed by the Layer 2 Switch or Layer 3 Switch. All other packets are filtered out.

•No packet received on a management port is sent to any in-band ports, and no packets received on in-band ports are sent to a management port.

•A management port is not part of any VLAN

•Protocols are not supported on the management port.

Brocade ICX 6650 Administration Guide	1
53-1002600-01

1 Management port overview

•Creating a management VLAN disables the management port on the device.

For switches, any in-band port may be used for management purposes. A router sends Layer 3 packets using the MAC address of the port as the source MAC address.

CLI Commands for use with the management port

The following CLI commands can be used with a management port.

To display the current configuration, use the show running-config interface management command.

Brocade(config-if-mgmt)#ip addr 10.44.9.64/24 Brocade(config)#show running-config interface management 1 interface management 1

Logging on through the CLI

Once an IP address is assigned to a Brocade device running Layer 2 software or to an interface on the Brocade device running Layer 3 software, you can access the CLI either through the direct serial connection to the device or through a local or remote Telnet session.

You can initiate a local Telnet or SNMP connection by attaching a cable to a port and specifying the assigned management station IP address.

The commands in the CLI are organized into the following levels:

•User EXEC – Lets you display information and perform basic tasks such as pings and traceroutes.

•Privileged EXEC – Lets you use the same commands as those at the User EXEC level plus configuration commands that do not require saving the changes to the system-config file.

Brocade ICX 6650 Administration Guide	3
53-1002600-01

1 Logging on through the CLI

•CONFIG – Lets you make configuration changes to the device. To save the changes across reboots, you need to save them to the system-config file. The CONFIG level contains sub-levels for individual ports, for VLANs, for routing protocols, and other configuration areas.

NOTE

By default, any user who can open a serial or Telnet connection to the Brocade device can access all these CLI levels. To secure access, you can configure Enable passwords or local user accounts, or you can configure the device to use a RADIUS or TACACS/TACACS+ server for authentication. refer to the Brocade ICX 6650 Switch Security Configuration Guide.

Online help

To display a list of available commands or command options, enter “?” or press Tab. If you have not entered part of a command at the command prompt, all the commands supported at the current CLI level are listed. If you enter part of a command, then enter “?” or press Tab, the CLI lists the options you can enter at this point in the command string.

If you enter an invalid command followed by ?, a message appears indicating the command was unrecognized. An example is given below.

Brocade(config)#rooter ip

Unrecognized command

Command completion

The CLI supports command completion, so you do not need to enter the entire name of a command or option. As long as you enter enough characters of the command or option name to avoid ambiguity with other commands or options, the CLI understands what you are typing.

Scroll control

By default, the CLI uses a page mode to paginate displays that are longer than the number of rows in your terminal emulation window. For example, if you display a list of all the commands at the global CONFIG level but your terminal emulation window does not have enough rows to display them all at once, the page mode stops the display and lists your choices for continuing the display. An example is given below.

aaa all-client appletalk arp

boot

some lines omitted for brevity...

ipx lock-address logging

mac

--More--, next page: Space, next line: Return key, quit: Control-c

The software provides the following scrolling options:

•Press the Space bar to display the next page (one screen at a time).

•Press the Return or Enter key to display the next line (one line at a time).

•Press Ctrl+C or Ctrl+Q to cancel the display.

Line editing commands

The CLI supports the following line editing commands. To enter a line-editing command, use the CTRL+key combination for the command by pressing and holding the CTRL key, then pressing the letter associated with the command.

TABLE 2	CLI line editing commands
Ctrl+Key combination		Description
Ctrl+A		Moves to the first character on the command line.
Ctrl+B		Moves the cursor back one character.
Ctrl+C		Escapes and terminates command prompts and ongoing tasks (such as
		lengthy displays), and displays a fresh command prompt.
Ctrl+D		Deletes the character at the cursor.
Ctrl+E		Moves to the end of the current command line.
Ctrl+F		Moves the cursor forward one character.
Ctrl+K		Deletes all characters from the cursor to the end of the command line.
Ctrl+L; Ctrl+R		Repeats the current command line on a new line.
Ctrl+N		Enters the next command line in the history buffer.
Ctrl+P		Enters the previous command line in the history buffer.
Ctrl+U; Ctrl+X		Deletes all characters from the cursor to the beginning of the command line.
Ctrl+W		Deletes the last word you typed.
Ctrl+Z		Moves from any CONFIG level of the CLI to the Privileged EXEC level; at the
		Privileged EXEC level, moves to the User EXEC level.

Using slot number, and port number with CLI commands

Many CLI commands require users to enter port numbers as part of the command syntax, and many show command outputs display port numbers. The port numbers are entered in the following format: stack-unit/slot/port.

The ports are labelled on the front panels of the devices.

CLI nomenclature on Brocade ICX 6650 models

When you enter CLI commands that include the port number as part of the syntax, you must use the stack unit/slot number/port number format. The unit number is 1. For example, the following commands change the CLI from the global CONFIG level to the configuration level for the first port on the device:

Brocade(config)#interface ethernet 1/1/1

Brocade(config-if-e1000-1/1/1)#

Syntax: ethernet <stack-unit>/<slot>/<port>

Searching and filtering output from CLI commands

You can filter CLI output from show commands and at the --More-- prompt. You can search for individual characters, strings, or construct complex regular expressions to filter the output.

Searching and filtering output from Show commands

You can filter output from show commands to display lines containing a specified string, lines that do not contain a specified string, or output starting with a line containing a specified string. The search string is a regular expression consisting of a single character or string of characters. You can use special characters to construct complex regular expressions. Refer to “Using special characters in regular expressions” on page 8 for information on special characters used with regular expressions.

Displaying lines containing a specified string

The following command filters the output of the show interface command for port 1/1/2 so it displays only lines containing the word “Internet”. This command can be used to display the IP address of the interface.

Brocade#show interface ethernet 1/1/2| include Internet

Internet address is 192.168.1.11/24, MTU 1518 bytes, encapsulation ethernet

Syntax: <show-command> | include <regular-expression>

NOTE

The vertical bar ( | ) is part of the command.

Note that the regular expression specified as the search string is case sensitive. In the example above, a search string of “Internet” would match the line containing the IP address, but a search string of “internet” would not.

Displaying lines that do not contain a specified string

The following command filters the output of the show who command so it displays only lines that do not contain the word “closed”. This command can be used to display open connections to the Brocade device.

Searching and filtering output at the --More-- prompt

The --More-- prompt displays when output extends beyond a single page. From this prompt, you can press the Space bar to display the next page, the Return or Enter key to display the next line, or Ctrl+C or Q to cancel the display. In addition, you can search and filter output from this prompt.

At the --More-- prompt, you can press the forward slash key ( / ) and then enter a search string. The Brocade device displays output starting from the first line that contains the search string, similar to the begin option for show commands. An example is given below.

--More--, next page: Space, next line: Return key, quit: Control-c /telnet

The results of the search are displayed.

As with the commands for filtering output from show commands, the search string is a regular expression consisting of a single character or string of characters. You can use special characters to construct complex regular expressions. See the next section for information on special characters used with regular expressions.

Using special characters in regular expressions

You use a regular expression to specify a single character or multiple characters as a search string. In addition, you can include special characters that influence the way the software matches the output against the search string. These special characters are listed in the following table.

TABLE 3	Special characters for regular expressions
Character	Operation
.	The period matches on any single character, including a blank space.
	For example, the following regular expression matches “aaz”, “abz”, “acz”, and so on, but not just
	“az”:
	a.z

*The asterisk matches on zero or more sequential instances of a pattern.

For example, the following regular expression matches output that contains the string “abc”, followed by zero or more Xs:

abcX*

	Using slot number, and port number with CLI commands	1
TABLE 3	Special characters for regular expressions (Continued)
Character	Operation

+The plus sign matches on one or more sequential instances of a pattern.

For example, the following regular expression matches output that contains "de", followed by a sequence of “g”s, such as “deg”, “degg”, “deggg”, and so on:

deg+

?The question mark matches on zero occurrences or one occurrence of a pattern.

For example, the following regular expression matches output that contains "dg" or "deg": de?g

NOTE: Normally when you type a question mark, the CLI lists the commands or options at that CLI level that begin with the character or string you entered. However, if you enter Ctrl+V and then type a question mark, the question mark is inserted into the command line, allowing you to use it as part of a regular expression.

^A caret (when not used within brackets) matches on the beginning of an input string. For example, the following regular expression matches output that begins with “deg”: ^deg

$	A dollar sign matches on the end of an input string.
	For example, the following regular expression matches output that ends with “deg”:
	deg$
_	An underscore matches on one or more of the following:
	•	, (comma)
	• { (left curly brace)
	• } (right curly brace)
	•	( (left parenthesis)
	•	) (right parenthesis)
	• The beginning of the input string
	• The end of the input string
	•	A blank space
	For example, the following regular expression matches on “100” but not on “1002”, “2100”, and
	so on.
	_100_
[ ]	Square brackets enclose a range of single-character patterns.
	For example, the following regular expression matches output that contains “1”, “2”, “3”, “4”, or
	“5”:
	[1-5]

You can use the following expression symbols within the brackets. These symbols are allowed only inside the brackets.

•^ – The caret matches on any characters except the ones in the brackets. For example, the following regular expression matches output that does not contain “1”, “2”, “3”, “4”, or “5”:

[^1-5]

•- The hyphen separates the beginning and ending of a range of characters. A match occurs if any of the characters within the range is present. See the example above.

|	A vertical bar separates two alternative values or sets of values. The output can match one or the
	other value.
	For example, the following regular expression matches output that contains either “abc” or “defg”:
	abc|defg
( )	Parentheses allow you to create complex expressions.
	For example, the following complex expression matches on “abc”, “abcabc”, or “defg”, but not on
	“abcdefgdefg”:
	((abc)+)|((defg)?)

1 Using slot number, and port number with CLI commands

If you want to filter for a special character instead of using the special character as described in the table above, enter “\” (backslash) in front of the character. For example, to filter on output containing an asterisk, enter the asterisk portion of the regular expression as “\*”.

Brocade#show ip route bgp | include \*

Creating an alias for a CLI command

You can create aliases for CLI commands. An alias serves as a shorthand version of a longer CLI command. For example, you can create an alias called shoro for the CLI command show ip route. Then when you enter shoro at the command prompt, the show ip route command is executed.

To create an alias called shoro for the CLI command show ip route, enter the alias shoro = show ip route command.

Brocade(config)#alias shoro = show ip route

Syntax: [no] alias <alias-name> = <cli-command>

The <alias-name> must be a single word, without spaces.

After the alias is configured, entering shoro at either the Privileged EXEC or CONFIG levels of the CLI, executes the show ip route command.

To create an alias called wrsbc for the CLI command copy running-config tftp 10.10.10.10 test.cfg, enter the following command.

Brocade(config)#alias wrsbc = copy running-config tftp 10.10.10.10 test.cfg

To remove the wrsbc alias from the configuration, enter one of the following commands.

Brocade(config)#no alias wrsbc

or

Brocade(config)#unalias wrsbc

Syntax: unalias <alias-name>

The specified <alias-name> must be the name of an alias already configured on the Brocade device.

To display the aliases currently configured on the Brocade device, enter the following command at either the Privileged EXEC or CONFIG levels of the CLI.

Brocade#alias	copy running-config tftp 10.10.10.10 test.cfg
wrsbc
shoro	show ip route

Syntax: alias

Configuration notes for creating a command alias

The following configuration notes apply to this feature:

•You cannot include additional parameters with the alias at the command prompt. For example, after you create the shoro alias, shoro bgp would not be a valid command.

•If configured on the Brocade device, authentication, authorization, and accounting is performed on the actual command, not on the alias for the command.

•To save an alias definition to the startup-config file, use the write memory command.
