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.
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.
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.
