Chapter 6 Configuring AnyConnect Features Using CLI Configuring, Enabling, and Using Other AnyConnect Features Configuring, Enabling, and Using Other AnyConnect Features The following sections describe how to configure other AnyConnect features. Some features, such as Secure Desktop and dynamic access policies, do not require that you specifically configure the AnyConnect client to interact with that feature. Rather, all configuration for those features occurs on the security appliance or within the software package itself. Configuring Certificate-only Authentication You can specify whether you want users to authenticate using AAA with a username and password or using a digital certificate (or both). When you configure certificate-only authentication, users can connect with digital certificate and are not required to provide a user ID and password. To configure certificate-only authentication using CLI, use the authentication command with the keyword certificate in tunnel-group webvpn mode. For example: hostname(config)# tunnel-group testgroup webvpn-attributes asa2(config-tunnel-webvpn)# authentication ? asa2(config-tunnel-webvpn)# authentication certificate Note You must configure ssl certificate-authentication interface port for this option to take effect. To configure certificate-only authentication using ASDM, select Configuration > Remote Access > Network (Client) Access > SSL VPN Connection Profiles, and in the Connection Profiles area, select Add or Edit. This displays the Add or Edit SSL VPN Connect Profile dialog box with the Basic option selected. In the Authentication area, specify only Certificate as the Method. Using Compression On low-bandwidth connections, compression increases the communications performance between the security appliance and the client by reducing the size of the packets being transferred. By default, compression for all SSL VPN connections is enabled on the security appliance, both at the global level and for specific groups or users. For broadband connections, compression might result in poorer performance. You can configure compression globally using the compression svc command from global configuration mode. You can also configure compression for specific groups or users with the svc compression command in group-policy and username webvpn modes. The global setting overrides the group-policy and username settings. Changing Compression Globally To change the global compression settings, use the compression svc command from global configuration mode: compression svc no compression svc To remove the command from the configuration, use the no form of the command. In the following example, compression is disabled for all SSL VPN connections globally: hostname(config)# no compression svc OL-12950-012 Cisco AnyConnect VPN Client Administrator Guide 6-5

Configuring AnyConnect Features Using CLI

Configuring, Enabling, and Using Other AnyConnect Features

The following sections describe how to configure other AnyConnect features. Some features, such as

Secure Desktop and dynamic access policies, do not require that you specifically configure the

AnyConnect client to interact with that feature. Rather, all configuration for those features occurs on the

security appliance or within the software package itself.

Configuring Certificate-only Authentication

You can specify whether you want users to authenticate using AAA with a username and password or

using a digital certificate (or both). When you configure certificate-only authentication, users can

connect with digital certificate and are not required to provide a user ID and password. To configure

certificate-only authentication using CLI, use the

authentication

command with the keyword

certificate

in tunnel-group webvpn mode. For example:

hostname(config)# tunnel-group testgroup webvpn-attributes

asa2(config-tunnel-webvpn)# authentication ?

asa2(config-tunnel-webvpn)# authentication certificate

Note

You must configure

ssl certificate-authentication interface

interface

port

> for this option to

take effect.

To configure certificate-only authentication using ASDM, select Configuration > Remote Access >

Network (Client) Access > SSL VPN Connection Profiles, and in the Connection Profiles area, select

Add or Edit. This displays the Add or Edit SSL VPN Connect Profile dialog box with the Basic option

selected. In the Authentication area, specify only Certificate as the Method.

Using Compression

On low-bandwidth connections, compression increases the communications performance between the

security appliance and the client by reducing the size of the packets being transferred. By default,

compression for all SSL VPN connections is enabled on the security appliance, both at the global level

and for specific groups or users. For broadband connections, compression might result in poorer

performance.

You can configure compression globally using the

compression svc

command from global configuration

mode. You can also configure compression for specific groups or users with the

svc compression

command in group-policy and username webvpn modes. The global setting overrides the group-policy

and username settings.

Changing Compression Globally

To change the global compression settings, use the

compression

svc

command from global

configuration mode:

compression

svc

compression

svc

To remove the command from the configuration, use the

form of the command.

In the following example, compression is disabled for all SSL VPN connections globally:

hostname(config)#

compression svc
