5.1 Various Maintenance Methods
5.1.1 Remote Deployment and Maintenance Using USB
As the network expands, more and more network devices are used and software
commissioning costs increase. USB-based deployment does not require software
commissioning, which reduces deployment costs.
Before using a USB flash drive to configure an AR, store software package and configuration
files on the USB flash drive. Software engineers do not need to commission devices onsite.
After installing the AR, hardware engineers will insert the USB flash drive into the USB
interface on the AR and power on the AR. After being started, the AR automatically loads and
upgrades the software.
5.1.2 SNMP-based Maintenance
The AR500&AR510&AR530&AR550&AR2500 supports the Simple Network Management
Protocol (SNMP) v1/v2c/v3 and the Client/Server model. The device can be managed by the
network management system (NMS), such as iManager U2000.
5.1.3 CLI-based Maintenance
The AR500&AR510&AR530&AR550&AR2500 provides the command line mode for local
or remote maintenance:
l Local maintenance using the console interface
l Local or remote maintenance using Telnet
l Secure shell (SSH) maintenance: guarantees security and provides authentication for
login users on an insecure network, and defends against various attacks, including IP
address spoofing, plain text password interception, and denial of service (DoS).
5.2 Fault Location
5.2.1 Device Fault Location
The AR500&AR510&AR530&AR550&AR2500 support the following functions to locate
device faults:
l Information center
After detecting a service error or recovery event, the
AR500&AR510&AR530&AR550&AR2500 provides unified management of logs,
traps, and debugging information, and redirects information to different directions for
fault location.
l Fast information collection
