Document Conventions

Warnings and Notes

These are how warnings and notes are shown in this CLI Reference Guide.

Warnings tell you about things that could harm you or your device. See your User’s Guide for product specific warnings.

Notes tell you other important information (for example, other things you may need to configure or helpful tips) or recommendations.

Syntax Conventions

This manual follows these general conventions:

•ZyXEL’s switches may be referred to as the “Switch”, the “device”, the “system” or the “product” in this Reference Guide.

•Units of measurement may denote the “metric” value or the “scientific” value. For example, “k” for kilo may denote “1000” or “1024”, “M” for mega may denote “1000000” or “1048576” and so on.

Command descriptions follow these conventions:

•	Commands are in courier new font.
•	Required input values are in angle brackets <>; for example, ping <ip> means that you
	must specify an IP address for this command.
•	Optional fields are in square brackets []; for instance show logins [name], the name
	field is optional.
	The following is an example of a required field within an optional field: snmp-server
	[contact <system contact>], the contact field is optional. However, if you
	use contact, then you must provide the system contact information.

•Lists (such as <port-list>) consist of one or more elements separated by commas. Each element might be a single value (1, 2, 3, ...) or a range of values (1-2, 3-5, ...) separated by a dash.

•The | (bar) symbol means “or”.

•italic terms represent user-defined input values; for example, in snmp-server [contact <system contact>], system contact can be replaced by the administrator’s name.

•A key stroke is denoted by square brackets and uppercase text, for example, [ENTER] means the “Enter” or “Return” key on your keyboard.

Ethernet Switch CLI Reference Guide

Document Conventions

•<cr> means press the [ENTER] key.

•An arrow (-->) indicates that this line is a continuation of the previous line.

Command summary tables are organized as follows:

Table 1 Example: Command Summary Table

COMMAND	DESCRIPTION	M	P
show vlan	Displays the status of all VLANs.	E	3
vlan <1-4094>	Enters config-vlan mode for the specified VLAN. Creates the	C	13
	VLAN, if necessary.
inactive	Disables the specified VLAN.	C	13
no inactive	Enables the specified VLAN.	C	13
no vlan <1-4094>	Deletes a VLAN.	C	13

The Table title identifies commands or the specific feature that the commands configure. The COMMAND column shows the syntax of the command.

•If a command is not indented, you run it in the enable or config mode. See Chapter 2 on page 14 for more information on command modes.

•If a command is indented, you run it in a sub-command mode.

The DESCRIPTION column explains what the command does. It also identifies legal input values, if necessary.

The M column identifies the mode in which you run the command.

•E: The command is available in enable mode. It is also available in user mode if the privilege level (P) is less than 13.

•C: The command is available in config (not indented) or one of the sub-command modes (indented).

The P column identifies the privilege level of the command. If you don’t have a high enough privilege level you may not be able to view or execute some of the commands. See Chapter 2 on page 14 for more information on privilege levels.

Make sure your computer IP address is in the same subnet, unless you are accessing the Switch through one or more routers.

Ethernet Switch CLI Reference Guide

Chapter 1 How to Access and Use the CLI

1.1.3 SSH

1Connect your computer to one of the Ethernet ports.

2Use a SSH client program to access the Switch. If this is your first login, use the default values in Table 3 on page 11 and Table 4 on page 12. Make sure your computer IP address is in the same subnet, unless you are accessing the Switch through one or more routers.

1.2Logging in

Use the administrator username and password. If this is your first login, use the default values.

Table 4 Default User Name and Password

SETTING	DEFAULT VALUE
User Name	admin

Password	1234

The Switch automatically logs you out of the management interface after five minutes of inactivity. If this happens to you, simply log back in again.

1.3Using Shortcuts and Getting Help

This table identifies some shortcuts in the CLI, as well as how to get help.

Table 5 CLI Shortcuts and Help

Ethernet Switch CLI Reference Guide

Chapter 1 How to Access and Use the CLI

1.4 Saving Your Configuration

When you run a command, the Switch saves any changes to its run-time memory. The Switch loses these changes if it is turned off or loses power. Use the write memory command in enable mode to save the current configuration permanently to non-volatile memory.

sysname# write memory

You should save your changes after each CLI session. All unsaved configuration changes are lost once you restart the Switch.

1.5Logging Out

Enter logout to log out of the CLI. You have to be in user, enable, or config mode. See Chapter 2 on page 14 for more information about modes.

Ethernet Switch CLI Reference Guide

Privilege Level and Command

Mode

This chapter introduces the CLI privilege levels and command modes.

•The privilege level determines whether or not a user can run a particular command.

•If a user can run a particular command, the user has to run it in the correct mode.

2.1Privilege Levels

Every command has a privilege level (0-14). Users can run a command if the session’s privilege level is greater than or equal to the command’s privilege level. The session’s privilege level initially comes from the login account’s privilege level, though it is possible to change the session’s privilege level after logging in.

2.1.1 Privilege Levels for Commands

The privilege level of each command is listed in the Reference A-G chapters on page 22.

At the time of writing, commands have a privilege level of 0, 3, 13, or 14. The following table summarizes the types of commands at each of these privilege levels.

Table 6 Types of Commands at Different Privilege Levels

PRIVILEGE LEVEL	TYPES OF COMMANDS AT THIS PRIVILEGE LEVEL
0	Display basic system information.

3	Display configuration or status.

13	Configure features except for login accounts, SNMP user accounts, the
	authentication method sequence and authorization settings, multiple logins,
	administrator and enable passwords, and configuration information display.

14	Configure login accounts, SNMP user accounts, the authentication method
	sequence and authorization settings, multiple logins, and administrator and
	enable passwords, and display configuration information.

2.1.2 Privilege Levels for Login Accounts

You can manage the privilege levels for login accounts in the following ways:

•Using commands. Login accounts can be configured by the admin account or any login account with a privilege level of 14. See Chapter 40 on page 173.

Ethernet Switch CLI Reference Guide

Chapter 2 Privilege Level and Command Mode

•Using vendor-specific attributes in an external authentication server. See the User’s Guide for more information.

The admin account has a privilege level of 14, so the administrator can run every command. You cannot change the privilege level of the admin account.

2.1.3 Privilege Levels for Sessions

The session’s privilege level initially comes from the privilege level of the login account the user used to log in to the Switch. After logging in, the user can use the following commands to change the session’s privilege level.

2.1.3.1 enable Command

This command raises the session’s privilege level to 14. It also changes the session to enable mode (if not already in enable mode). This command is available in user mode or enable mode, and users have to know the enable password.

In the following example, the login account user0 has a privilege level of 0 but knows that the enable password is 123456. Afterwards, the session’s privilege level is 14, instead of 0, and the session changes to enable mode.

sysname> enable Password: 123456 sysname#

The default enable password is 1234. Use this command to set the enable password. password <password>

<password> consists of 1-32 alphanumeric characters. For example, the following command sets the enable password to 123456. See Chapter 89 on page 311 for more information about this command.

sysname(config)# password 123456

The password is sent in plain text and stored in the Switch’s buffers. Use this command to set the cipher password for password encryption.

password cipher <password>

<password> consists of 32 alphanumeric characters. For example, the following command encrypts the enable password with a 32-character cipher password. See Chapter 53 on page 208 for more information about this command.

sysname(config)# password cipher qwertyuiopasdfghjklzxcvbnm123456

2.1.3.2 enable <0-14> Command

This command raises the session’s privilege level to the specified level. It also changes the session to enable mode, if the specified level is 13 or 14. This command is available in user mode or enable mode, and users have to know the password for the specified privilege level.

Ethernet Switch CLI Reference Guide

Chapter 2 Privilege Level and Command Mode

In the following example, the login account user0 has a privilege level of 0 but knows that the password for privilege level 13 is pswd13. Afterwards, the session’s privilege level is 13, instead of 0, and the session changes to enable mode.

sysname> enable 13 Password: pswd13 sysname#

Users cannot use this command until you create passwords for specific privilege levels. Use the following command to create passwords for specific privilege levels.

password <password> privilege <0-14>

<password> consists of 1-32 alphanumeric characters. For example, the following command sets the password for privilege level 13 to pswd13. See Chapter 89 on page 311 for more information about this command.

sysname(config)# password pswd13 privilege 13

2.1.3.3 disable Command

This command reduces the session’s privilege level to 0. It also changes the session to user mode. This command is available in enable mode.

2.1.3.4 show privilege command

This command displays the session’s current privilege level. This command is available in user mode or enable mode.

sysname# show privilege Current privilege level : 14

2.2 Command Modes

The CLI is divided into several modes. If a user has enough privilege to run a particular command, the user has to run the command in the correct mode. The modes that are available depend on the session’s privilege level.

2.2.1 Command Modes for Privilege Levels 0-12

If the session’s privilege level is 0-12, the user and all of the allowed commands are in user mode. Users do not have to change modes to run any allowed commands.

Ethernet Switch CLI Reference Guide

Chapter 2 Privilege Level and Command Mode

2.2.2 Command Modes for Privilege Levels 13-14

If the session’s privilege level is 13-14, the allowed commands are in one of several modes.

Table 7 Command Modes for Privilege Levels 13-14 and the Types of Commands in Each One

MODE	PROMPT	COMMAND FUNCTIONS IN THIS MODE
enable	sysname#	Display current configuration, diagnostics, maintenance.
config	sysname(config)#	Configure features other than those below.
config-interface	sysname(config-interface)#	Configure ports.
config-mvr	sysname(config-mvr)#	Configure multicast VLAN.
config-route-	sysname(config-if)#	Enable and enter configuration mode for an IPv4 or IPv6
domain		routing domain.
config-dvmrp	sysname(config-dvmrp)#	Configure Distance Vector Multicast Routing Protocol
		(DVRMP).
config-igmp	sysname(config-igmp)#	Configure Internet Group Management Protocol (IGMP).
config-ma	sysname(config-ma)#	Configure an Maintenance Association (MA) in
		Connectivity Fault Management (CFM).
config-ospf	sysname(config-ospf)#	Configure Open Shortest Path First (OSPF) protocol.
config-rip	sysname(config-rip)#	Configure Routing Information Protocol (RIP).
config-vrrp	sysname(config-vrrp)#	Configure Virtual Router Redundancy Protocol (VRRP).

Each command is usually in one and only one mode. If a user wants to run a particular command, the user has to change to the appropriate mode. The command modes are organized like a tree, and users start in enable mode. The following table explains how to change from one mode to another.

Table 8 Changing Between Command Modes for Privilege Levels 13-14

MODE	ENTER MODE	LEAVE MODE
enable	--	--
config	configure	exit
config-interface	interface port-channel <port-list>	exit
config-mvr	mvr <1-4094>	exit
config-vlan	vlan <1-4094>	exit
config-route-domain	interface route domain <ip-address>/<mask-bits>	exit
config-dvmrp	router dvmrp	exit

Chapter 2 Privilege Level and Command Mode

2.3 Listing Available Commands

Use the help command to view the executable commands on the Switch. You must have the highest privilege level in order to view all the commands. Follow these steps to create a list of supported commands:

1Log into the CLI. This takes you to the enable mode.

2Type help and press [ENTER]. A list comes up which shows all the commands available in enable mode. The example shown next has been edited for brevity’s sake.

sysname# help Commands available:

help logout exit history

enable <0-14> enable <cr>

traceroute <ip|host-name> [vlan <vlan-id>][..] traceroute help

ssh <1|2> <[user@]dest-ip> <cr>

ssh <1|2> <[user@]dest-ip> [command </>] sysname#

3Copy and paste the results into a text editor of your choice. This creates a list of all the executable commands in the user and enable modes.

4Type configure and press [ENTER]. This takes you to the config mode.

5Type help and press [ENTER]. A list is displayed which shows all the commands available in config mode and all the sub-commands. The sub-commands are preceded by the command necessary to enter that sub-command mode. For example, the command name <name-str> as shown next, is preceded by the command used to enter the config-vlan sub-mode: vlan <1-4094>.

sysname# help

no arp inspection log-buffer logs no arp inspection filter-aging-time no arp inspection <cr>

vlan <1-4094>

vlan <1-4094> name <name-str> vlan <1-4094> normal <port-list> vlan <1-4094> fixed <port-list>

6Copy and paste the results into a text editor of your choice. This creates a list of all the executable commands in config and the other submodes, for example, the config-vlan mode.

Ethernet Switch CLI Reference Guide

Initial Setup

This chapter identifies tasks you might want to do when you first configure the Switch.

3.1Changing the Administrator Password

It is recommended you change the default administrator password. You can encrypt the password with a cipher password. See Chapter 53 on page 208 for more information.

Use this command to change the administrator password. admin-password <pw-string> <Confirm-string>

where <pw-string> may be 1-32 alphanumeric characters long.

sysname# configure

sysname(config)# admin-password t1g2y7i9 t1g2y7i9

3.2Changing the Enable Password

It is recommended you change the default enable password. You can encrypt the password with a cipher password. See Chapter 53 on page 208 for more information.

Use this command to change the enable password. password <password>

where <password> may be 1-32 alphanumeric characters long.

sysname# configure

sysname(config)# password k8s8s3dl0

Ethernet Switch CLI Reference Guide

Chapter 3 Initial Setup

3.3 Prohibiting Concurrent Logins

By default, multiple CLI sessions are allowed via the console port or Telnet. See the User’s Guide for the maximum number of concurrent sessions for your Switch. Use this command to prohibit concurrent logins.

no multi-login

Console port has higher priority than Telnet. See Chapter 50 on page 197 for more multilogin commands.

sysname# configure sysname(config)# no multi-login

3.4 Changing the Management IP Address

The Switch has a different IP address in each VLAN. By default, the Switch has VLAN 1 with IP address 192.168.1.1 and subnet mask 255.255.255.0. Use this command in config-vlan mode to change the management IP address in a specific VLAN.

ip address <ip> <mask>

This example shows you how to change the management IP address in VLAN 1 to 172.16.0.1 with subnet mask 255.255.255.0.

sysname# configure sysname(config)# vlan 1

sysname(config-vlan)# ip address default-management 172.16.0.1 255.255.255.0

Afterwards, you have to use the new IP address to access the Switch.

3.5Changing the Out-of-band Management IP Address

If your Switch has a MGMT port (also referred to as the out-of-band management port), then the Switch can also be managed via this interface. By default, the MGMT port IP address is 192.168.0.1 and the subnet mask is 255.255.255.0. Use this command in config mode to change the out-of-band management IP address.

ip address <ip> <mask>

This example shows you how to change the out-of-band management IP address to 10.10.10.1 with subnet mask 255.255.255.0 and the default gateway 10.10.10.254

sysname# configure

sysname(config)# ip address 10.10.10.1 255.255.255.0 sysname(config)# ip address default-gateway 10.10.10.254
