Just to inform you.

A new version of eNSP has been released.

Besides some features have been modified, new devices have been added to Huawei Network Simulation Platform (eNSP):

Frame Relay switch
Cloud device
Hub.

how to configure multiple interfaces at the same time

8 Nov, 2012 How To 0

This is an useful feature, specially if we want to configure Huawei’s switch, where there are lots of physical interfaces. Very often, some of interfaces have the same configuration. Instead of configure the interfaces one by one it is easier to configure multiple interfaces at the same time. It improves the efficiency.

Let’s assume that you want to add 5 GE interfaces to VLAN 100:

[labnario]port-group labnario
[labnario-port-group-labnario]group-member GigabitEthernet 0/0/1 to GigabitEthernet 0/0/5
[labnario-port-group-labnario]port link-type access
[labnario-port-group-labnario]port default vlan 100

[labnario]dis cur | beg port-group
port-group labnario
 group-member GigabitEthernet0/0/1
 group-member GigabitEthernet0/0/2
 group-member GigabitEthernet0/0/3
 group-member GigabitEthernet0/0/4
 group-member GigabitEthernet0/0/5

from Huawei CLI – debugging …

  ...

<labnario>debugging ip icmp

To send debugging information to terminal:

<labnario>terminal monitor
Info: Current terminal monitor is on.
<labnario>terminal debugging
Info: Current terminal debugging is on.

To display which debugging functions are enabled:

<labnario>display debugging
IP icmp debugging is on

SNMPv2c configuration on Huawei devices

24 Oct, 2012 System Management 0

Simple Network Management Protocol (SNMP) is widely used for IP networks’ devices management and monitoring. Not only routers and switches can be managed using SNMP. It can be used with servers, modems, printers, etc. It is application layer protocol and is defined as IETF standard.

How SNMP works?

It operates based on the following components:

Network Management Station (NMS), sends SNMP requests to query managed devices and receives alarms send by these devices. NMS uses the MIB to identify and manage device objects.
Agent – process running on the managed device which is responsible for sending alarms to the NMS and processing requests received from NMS.
Managed device – a networking device on which the Agent process is running.

Huawei eNSP – continuation

19 Oct, 2012 General 0

Some time ago I wrote about Huawei Network Simulation Platform eNSP. I have been testing it since it was launched. It is still being developed and new VRP features will be available soon. It looks like it is really useful tool if you want to study Huawei’s datacom technology.

I’ve just found a video guide for eNSP at Huawei’s forum. I hope it will be informative for you.

Anyway, a background music of this guide will have a calming influence on you 🙂
