l If you specify the password keyword to authenticate users with the local password, remember to set the local password using the set authentication password { cipher | simple } password command.

l If you specify the scheme keyword to authenticate users locally or remotely with usernames and passwords, the actual authentication mode, that is, local or remote, depends on related configuration.

If this command is executed with the command-authorization keyword, authorization is performed on the TACACS server whenever you attempt to execute a command, and the command can be executed only when you pass the authorization. The available commands are defined on a TACACS server for different users. When you specify to perform local password authentication on the Console port, users logging in through the Console port can log into the switch without password; whereas on other user interfaces, a password needs to be configured for users (such as VTY users) to log into the switch.

By default, users logging in through the Console port are not authenticated, whereas modem users and Telnet users are authenticated with password.

1.1.8 header

Syntax

header [ incoming | login | shell ] text

undo header { incoming | login | shell }

View

System view

Parameters

incoming: Sets the incoming banner for users that log in through modems. If authentication is required, the banner appears after a Modem user passes the authentication. (The session banner does not appear in this case.)

login: Sets the login banner. The banner set by this keyword is valid only when authentication is required for users’ login, and appears while the switch prompts for inputting username and password.

shell: Sets the session banner, which appears after a session is established. If authentication is required, the banner appears after a user passes the authentication.

text: Banner to be displayed. If no keyword (incoming, login, or shell) is specified, this argument is the login banner by default. You can provide this argument in two ways.

l Enter the banner in the same line as the command (A command line can accept up to 254 characters, including the keywords and spaces).

l Enter the banner in multiple lines (you can start a new line by pressing <Enter>,) where you can enter a banner that can contain up to 2000 characters (including the invisible characters).

Note that the first character is treated as the beginning character and the end character of the banner. After entering the end character, you can press <Enter> to exit the interaction.

Description

Use the header command to set the banners that are displayed when a user logs into a switch. The login banner is displayed on the terminal when the connection is established. And the session banner is displayed on the terminal if a user successfully logs in.

Use the undo header command to disable displaying a specific banner or all banners.

Note that if you specify any one of the three keywords without providing the text argument, the specified keyword will be regarded as the content of the login banner.

You can specify the banner in the following three ways, each of which requires that the first character and the last character of the banner be the same.

l Enter the banner in multiple lines. If you only type one character in the first line of a banner, the character and the last character do not act as part of the banner. The following gives an example of this way.

[H3C] header shell 0

Input banner text, and quit with the character '0'.

Welcome!0

When you log in the next time, “Welcome!” is displayed as the banner. The beginning character and the end character (character 0) do not appear.

l Enter the banner in multiple lines. If you type multiple characters in the first line of a banner and the beginning and the end characters of the banner in this line are not the same, the beginning character is part of the banner. The following is an example.

[H3C] header shell hello

Input banner text, and quit with the character 'h'.

my friend !

When you log in the next time, “hello” and “my friend !“ is displayed respectively in two lines as the banner. The beginning character “h” appears in the banner.

l Enter the banner in a single line. You can also specify the banner in a single line. In this case, the banner does contain the beginning and the end character. The following is an example.

[H3C] header shell 0welcome,my friend!0

When you log in the next time, “welcome, my friend!” is displayed as the banner.

Examples

# Set the session banner.

Option 1: Enter the banner in the same line as the command.

<H3C> system-view

System View: return to User View with Ctrl+Z.

[H3C] header shell %SHELL: Hello! Welcome%

Parameters

acl-number: ACL number ranging from 2,000 to 3,999.

inbound: Filters the users Telneting to the current switch.

outbound: Filters the users Telneting to other switches from the current switch.

Description

Use the acl command to apply an ACL to filter Telnet users.

Use the undo acl command to disable the switch from filtering Telnet users through the ACL.

By default, Telnet users are not filtered by ACLs.

Examples

# Apply ACL 2000 to filter users Telneting to the current switch (assuming that ACL 2,000 already exists.)

<H3C> system-view

System View: return to User View with Ctrl+Z.

2.1.2 snmp-agent community

Syntax

snmp-agent community { read | write } community-name [ mib-view view-name | acl acl-number ]*

undo snmp-agent community community-name

View

System view

Parameters

read: Specifies that the community has read-only permission in the specified view.

write: Specifies that the community has read/write permission in the specified view.

community-name: Community name. A string ranges from 1 to 32 characters.

mib-view: Sets the name of the MIB view accessible to the community.

acl acl-number: Specifies the ACL number. The acl-number argument ranges from 2,000 to 2,999.

Description

Use the snmp-agent community command to set a community name and to enable users to access the switch through SNMP. You can also optionally use this command to apply an ACL to filter network management users.

Use the undo snmp-agent community command to cancel community-related configuration for the specified community.

By default, SNMPv1 and SNMPv2c access a switch by community names.

Examples

# Set the community name to h123, enable users to access the switch with the community name (with read-only permission), and apply ACL 2,000 to filter network management users (assuming that ACL 2000 already exists.)

<H3C> system-view

System View: return to User View with Ctrl+Z.

Parameters

v1: Specifies to adopt v1 security scheme.

v2c: Specifies to adopt v2c security scheme.

v3: Specifies to adopt v3 security scheme.

group-name: Group name. This argument can be of 1 to 32 characters.
