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.

Note: 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, 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.

• In some commands you specify slots or interfaces by the Access ID <aid>, use “?” to show which types of interfaces you can specify. For example, you might be able to use: slot-<slot> | <ge|msc>-<slot>-<port> | <ge|msc>-<slot>-<port>&&-<port>.

• Use “msc-<slot>-<port>” for an uplink slot on the management switch card.

• Use “ge-<slot>-<port>” for a Gigabit Ethernet port or switch settings on a PON interface.

• Use “pon-<slot>-<port>” to configure PON interface settings.

• A “slot” is a chassis slot.

• The “port” is 1-N where N is the number of ports on the card.

• Use && to specify a range of ports.

•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, ...) separate d b y 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.

ping <ip> means that you must

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 13 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 do not have a high enough privilege level you may not be able to view or execute some of the commands. See Chapter 2 on page 13 for more information on privilege levels.

SETTING DEFAULT VALUE

IP Address 192.168.1.1 Subnet Mask 255.255.255.0

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

1.1.3 SSH

1 Connect your computer to one of the Ethernet ports.

2 Use a SSH client program to access the Switch. If this is your first login, use the default values in Table 3 on

page 10 and Table 4 on page 11. Make sure your computer IP address is in the same subnet, unless you

are accessing the Switch through one or more routers.

1.2 Logging 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

Note: The Switch automatically logs you out of the management interface after 5 minutes of

inactivity. If this happens to you, simply log back in again.

Chapter 1 How to Use the CLI

1.3 Using 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

sysname# write memory

Ethernet Switch CLI Reference Guide

Note: You should save your changes after each CLI session. All unsaved configuration

changes are lost once you restart the Switch.

1.5 Logging Out

Enter logout to log out of the CLI. You have to be in user, enable, or config mode. See Chapter 2 on

page 13 for more information about modes.

Chapter 1 How to Use the CLI

Ethernet Switch CLI Reference Guide

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.

2.1 Privilege 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.

CHAPTER 2

Privilege Level and

Command Mode

2.1.1 Privilege Levels for Commands

The privilege level of each command is listed in the Reference A-G chapters on page 25.

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, admi nistrator 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 45 on page 191.

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 Section 60.2 on page 239 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 Section 60.2 on page 239 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

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 Section 60.2 on page 239 for more information about this command.

sysname(config)# password pswd13 privilege 13

2.1.3.3 disable Command

Chapter 2 Privilege Level and Command Mode

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

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:

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

2 Type 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#

3 Copy 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.

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

5 Type 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>

6 Copy 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.

CHAPTER 3

Initial Setup

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

3.1 Changing the Administrator Password

Note: It is recommended you change the default administrator password. You can encrypt

the password using the password encryption command. See Chapter 60 on page

239 for more information.

Use this command to change the administrator password.

admin-password <pw-string> <Confirm-string>

Up to 32 characters are allowed for the new password except [ ? ], [ | ], [ ' ], [ " ], [ space ], or [ , ].

sysname# configure sysname(config)# admin-password t1g2y7i9 t1g2y7i9

3.2 Changing the Enable Password

Note: It is recommended you change the default enable password. You can encrypt the

password using the password encryption command. See Chapter 60 on page 239 for more information.

Use this command to change the enable password.

password <password>

Up to 32 characters are allowed for the new password except [ ? ], [ | ], [ ' ], [ " ], [ space ], or [ , ].

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 through 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 55 on page 217 for more 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

multi-login

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

3.5 Changing 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 through 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

Ethernet Switch CLI Reference Guide

Chapter 3 Initial Setup

3.6 Using Auto Configuration

Follow the steps below to set up configurations on the Switch, so you can load an auto configuration file automatically from a TFTP server when you reboot the Switch.

Note: You need to set up configurations on a DHCP server and TFTP server first to use auto

configuration.

1 Use this command to enable auto configuration on the Switch.

auto-config

sysname# config sysname(config)# auto-config

2 Use this command to enable the DHCP mode for auto configuration.

auto-config dhcp

sysname# config sysname(config)# auto-config dhcp

3 Use this command to configure the Switch as a DHCP client.

ip address default-management dhcp-bootp

sysname# config sysname(config)# vlan 1 sysname(config-vlan)# ip address default-management dhcp-bootp

4 Use this command to enable DHCP option 60.

ip address default-management dhcp-bootp option-60

When you enable DHCP option 60, make sure you set up a Vendor Class Identifier. The Vendor Class Identifier specifies the Zyxel switch that should receive the auto configuration file. Skip this step if you are not enabling DHCP option 60.

sysname# config sysname(config)# vlan 1 sysname(config-vlan)# ip address default-management dhcp-bootp option-60

5 Use this command to define a Vendor Class Identifier for DHCP option 60.

ip address default-management dhcp-bootp option-60 class-id <class-id>

In this example, we use “ZyxelCorp”. Skip this step if you don’t need to define a Vendor Class Identifier.

sysname# config sysname(config)# vlan 1 sysname(config-vlan)# ip address default-management dhcp-bootp option-60 class-id ZyxelCorp

7 You need to save the current configuration in a configuration file, so the Switch will load the auto

configuration files from the TFTP server automatically when rebooting. Use this command to save the current configuration in a configuration file.

write memory [<index>]

For [<index>], you can enter a value to save the current configuration to a specified configuration file. 1 is for Config 1, and 2 is for Config 2.

In this example, we save the current configuration to Config 1.

sysname# write memory 1

........................................................................

............................

8 Use this command to reboot the Switch.

reload config [1|2]

For [1|2], 1 is for Config 1, and 2 is for Config 2.

In this example, we load Config 1 to reboot the Switch.

Ethernet Switch CLI Reference Guide

Use these commands to configure anti-Arpscan on the Switch.

5.1 Anti-Arpscan Overview

Address Resolution Protocol (ARP), RFC 826, is a protocol used to convert a network-layer IP address to a link-layer MAC address. ARP scan is used to scan the network of a certain interface for alive hosts. It shows the IP address and MAC addresses of all hosts found. Hackers could use ARP scan to find targets in your network. Anti-arpscan is used to detect unusual ARP scan activity and block suspicious hosts or ports.

Unusual ARP scan activity is determined by port and host thresholds that you set. A port threshold is determined by the number of packets received per second on the port. If the received packet rate is over the threshold, then the port is put into an Err-Disable state. You can recover the normal state of the port manually if this happens and after you identify the cause of the problem.

CHAPTER 5

Anti-Arpscan

A host threshold is determined by the number of ARP-request packets received per second. There is a global threshold rate for all hosts. If the rate of a host is over the threshold, then that host is blocked by using a MAC address filter. A blocked host is released automatically after the MAC aging time expires.

Note: A port-based threshold must be larger than the host-based threshold or the host-based

threshold will not work.

5.2 Command Summary
