Juniper Networks SSG 20 Backup Untrust Interface Configuration, Basic Wireless Configuration

Backup Untrust Interface Configuration

The SSG 20 device allows you to configure a backup interface for untrust failover. To set a backup interface for untrust failover, perform the following steps:

1.Set the backup interface in the Null security zone with the unset interface interface [port interface] CLI command.

2.Bind the backup interface to the same security zone as the primary interface with the set interface interface zone zone_name CLI command.

NOTE: The primary and backup interfaces must be in the same security zone. One primary interface has only one backup interface, and one backup interface has only one primary interface.

To set the ethernet0/4 interface as the backup interface to the ethernet0/0 interface, use the WebUI or CLI as follows:

WebUI

Network > Interfaces > Backup > Enter the following, then click Apply.

Primary: ethernet0/0

Backup: ethernet0/4

Type: track-ip (select)

CLI

unset interface bgroup0 port ethernet0/4 set interface ethernet0/4 zone untrust

set interface ethernet0/0 backup interface ethernet0/4 type track-ip save

Basic Wireless Configuration

This section provides information for configuring the wireless interface on the SSG 20-WLAN device. Wireless networks consist of names referred to as Service Set Identifiers (SSIDs). Specifying SSIDs allows you to have multiple wireless networks reside in the same location without interfering with each other. An SSID name can have a maximum of 32 characters. If a space is part of the SSID name string, then the string must be enclosed with quotation marks. Once the SSID name is set, more SSID attributes can be configured.To use the wireless local area network (WLAN) capabilities on the device, you must configure at least one SSID and bind it to a wireless interface.

The SSG 20-WLAN device allows you to create up to 16 SSIDs, but only 4 of them can be used simultaneously. You can configure the device to use the 4 SSIDs on either one of the transceivers or split the use on both (for example, 3 SSIDs assigned to WLAN 0 and 1 SSID assigned to WLAN 1.) Use the set interface wireless_interface wlan {0 1 both} CLI command to set the radio transceivers on the SSG 20-WLAN device.
