Labnario Huawei From Scratch

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:

And after the holidays …

We can bring up a subject of 10GE interfaces on Huawei CX600-X1-X2 platform. The short subject but can be useful.

Let’s imagine that you have NPUI board installed on the router:

<CX600>display elabel 1

BoardType=CX67NPUI20
Item=03030MDQ
Description=CX600,CX67NPUI20,Network Processing Unit Integrated with 2-Port 10GBase LAN/WAN-XFP

SCP is a secure file transfer, based on SSH2.0, which supports downloading and uploading files between SCP client and server, in batches as well. If you would like to know more, just visit Huawei support website. I will focus on practice and show this feature, using simple lab:

Configure communication between loopback interfaces of the server and the client. Below the SCP_server as an example. As this is a simple topology, I used RIP protocol for communication (long unused by me):

#
sysname SCP_server
#
vlan batch 100
#
interface Vlanif100
 ip address 10.1.1.1 255.255.255.0
#
interface MEth0/0/1
#
interface GigabitEthernet0/0/1
 port link-type trunk
 port trunk allow-pass vlan 100
#
interface LoopBack0
 ip address 1.1.1.1 255.255.255.255
#
rip 1
 network 10.0.0.0
 network 1.0.0.0
