What is NQA?

It is a feature that functions above link layer to measure performance of protocols running at the network layer, transport layer and application layer. It is useful to monitor network and locate faults occurring in the network. NQA can accurately test the network and collect statistics as well. You can configure and display NQA statistics through CLI but, as NQA is fully supported by Huawei NMS, you can also do this in GUI.

Most of Huawei devices support NQA but configuration can vary a little bit between NE routers, AR routers and switches. Of course we can perform more advanced test on carrier class devices. In this post we will focus on CLI and use CX600 router as an example.

NQA tests supported by CX600:

• • ICMP test
  • DHCP test
  • FTP test
  • HTTP test
  • DNS test
  • Traceroute test
  • SNMP test
  • TCP test
  • UDP test
  • ICMP Jitter test
  • UDP Jitter test
  • LSP Ping test
  • LSP Traceroute test
  • LSP Jitter test

Any time you want to upgrade huawei’s device you have 2 methods to do this. The first of them is to use CLI (command line interface), the second is to use bootrom menu. Using CLI is the most popular method. You can configure FTP server on the device and use your PC as FTP client or install FTP server on your PC and treat the device as FTP client. Anyway, you can use TFTP or serial (slow connection) instead of FTP. Sometimes it is not possible to get CLI because there is a problem with software file. It is damaged or does not exist. In this case we can use bootrom menu to download a new software and upgrade the device. Let’s take S5300 as an example.

Upgrade of Huawei S5300 switch from CLI

Huawei S5300 as FTP server:

#
FTP server enable
#
local-user labnario password simple labnario
local-user labnario privilege level 15
local-user labnario ftp-directory flash:
local-user labnario service-type ftp
#
interface MEth0/0/1
 ip address 192.168.0.20 255.255.255.0
#

How to log into Huawei S3300 switch? It is very simple. Which method you will chose depends on what you want to do on this device. If you want to upload file to or download it from the switch, use FTP or SFTP. If you want to configure the switch, use telnet, SSH or HTTP methods. Each time you can access the switch using console port,  locally or remotely, in case a console server is configured.

telnet S3300

#
telnet server enable
#

local-user labnario password cipher &EU15O"Q3/;Q=^Q`MAF4
local-user labnario privilege level 15
local-user labnario service-type telnet
#
