AF-5X User Guide

Ubiquiti Networks, Inc.

• Ping Interval Specify the time interval (in seconds)

between the ICMP echo requests that are sent by Ping

Watchdog. The default value is 300 seconds.

• Startup Delay Specify the initial time delay (in seconds)

until the first ICMP echo requests are sent by Ping

Watchdog. The default value is 300 seconds.

The Startup Delay value should be at least 60 seconds

as the network interface and wireless connection

initialization takes a considerable amount of time if the

AF-5X is rebooted.

• Failure Count to Reboot Specify the number of ICMP

echo response replies. If the specified number of ICMP

echo response packets is not received continuously,

Ping Watchdog will reboot the AF-5X. The default value

is 3.

• Save Support Info This generates a support

information file.

SNMP Agent

Simple Network Monitor Protocol (SNMP) is an application

layer protocol that facilitates the exchange of management

information between network devices. Network

administrators use SNMP to monitor network-attached

devices for issues that warrant attention.

The AF-5X contains an SNMP Agent, which does the

following:

• Provides an interface for device monitoring using SNMP

• Communicates with SNMP management applications

for network provisioning

• Allows network administrators to monitor network

performance and troubleshoot network problems

For the purpose of equipment identification, configure the

SNMP Agent with contact and location information:

SNMP Agent Enables the SNMP Agent.

• SNMP Community Specify the SNMP community

string. It is required to authenticate access to

Management Information Base (MIB) objects and

functions as an embedded password. The AF-5X also

supports a read-only community string; authorized

management stations have read access to all the objects

in the MIB except the community strings, but do not

have write access. The AF-5X supports SNMP v1. The

default SNMP Community is public.

• Contact Specify the contact who should be notified in

case of emergency.

• Location Specify the physical location of the AF-5X.

Web Server

Secure Connection (HTTPS) If enabled, the Web Server

uses secure HTTPS mode.

• Secure Server Port If secure HTTPS mode is used,

specify the TCP/IP port of the Web Server.

Server Port If HTTP mode is used, specify the TCP/IP port

of the Web Server.

Session Timeout Specifies the maximum timeout before

the session expires. Once a session expires, you must log

in again using the username and password.

SSH Server

SSH Server This option enables SSH access to the AF-5X.

• Server Port Specify the TCP/IP port of the SSH Server.

• Password Authentication If enabled, you must

authenticate using administrator credentials to grant

SSH access to the AF-5X; otherwise, an authorized key is

required.

for SSH access to the AF-5X instead of using an admin

password.
