Labnario Huawei From Scratch

I’ve had only one case when I used this command and … full success.

Sometimes it can happen that the file system doesn’t work properly. When you run dir command, you can find the space, which usage status is unknown. The system prompts you that the file system should be restored. Then you can run fixdisk command to release the unknown space.

Notice that:

• It is not recommended to use it when the file system works correctly.
• It doesn’t help when physical medium is damaged.
• Do not use it when CPU usage is high.

Lost chains in flash detected, please use fixdisk to recover them!

A new Huawei network simulator eNSP has been released.

You can download it clicking on the picture below:

Anyway, the first version of Huawei eNSP was introduced one year ago. I would like to know your opinions about the simulator. What is your experience with it? Is it helpful of useless for you? Feel free to express you thoughts.

Some time ago I wrote about interface policy-based routing PBR. Today I will show you example of local PBR configuration on Huawei AR routers. Local PBR allows you to forward packets through different interfaces or to different hops. Unlike interface PBR, local PBR is used for locally generated packets and classifies packets based on source addresses or packet lengths.

Let’s look at the topology and configure as follows:

1. Locally generated ICMP packets (with the size of 70-1300 bytes) will be sent to next hop IP address 172.16.0.2.
2. Locally generated ICMP packets (with the size of 1301-1500 bytes) will be sent to outbound interface GE0/0/1.

Configure IP addresses and static routes to ensure connectivity between loopback interfaces of both routers:

I have never used it but it looks interesting. Arp-ping lets us to check whether a specified IP address or MAC address is being used in a LAN. Intrigued, I opened Huawei eNSP simulator to check this feature. Results are not fully satisfied. As arp-ping IP works correctly, I cannot say the same about arp-ping MAC. There are some problems with communication between router and hosts. It looks like router does not receive ICMP Echo Reply packets from hosts in the LAN. I checked the same between router and switch “labnario_SW2″. Results look promising. Let’s pass on to the lab.

Labnario_RT config:

#
vlan batch 100 200
#
interface Vlanif100
 ip address 10.0.0.100 255.255.255.0 
#
interface Ethernet0/0/0
 port link-type trunk
 port trunk allow-pass vlan 100
#
interface GigabitEthernet0/0/1
 ip address 172.16.0.100 255.255.255.0

Huawei ATN950B routers are designed and intended for Metropolitan Area Networks. They are relatively new devices and often used in IP RAN solutions for 2G, 3G and LTE.

But I would not like to describe this product. Let’s focus on console cable for ATN950B.

Let’s imagine you have such router, power it on and try to connect to console port. And … nothing …, no any prompt. A standard console cable, you used for NE40E or CX600, does not work.

Do not panic, do it yourself using standard console cable. How to do this? Look below:
