VLANs in Huawei

Setting name and setting description is different.
If

dis vlan 101

is run, the output will show the description and not the name.
Alternatively you can find the status of a VLAN using its name:

dis vlan vlan-name NAGPUR

Cisco TechNotes

What is the difference between the two methods to create static routes?

There are two methods to create static routes:

The ip route 10.1.1.1 255.255.255.0 eth 0/0 command generates an ARP broadcast that looks for the next-hop IP address.
The ip route 10.1.1.1 255.255.255.0 172.16.1.1 command does not generate an ARP request. It keeps Layer 2 out of the routing process.

General Debugging Commands:

term len 0

terminal length

To set the number of lines of output to display on the terminal screen for the current session before pausing, use the terminal length command. To revert to the default, use the no form of this command.

terminal length lines

terminal no length

Syntax Description

lines

Number of lines to display. The range is from 0 to 511. Use 0 to not pause while displaying output.

Google Caching

Following are some key points to remember from Google's perspective when deploying GCC in ISP Network:

Please be aware that advertising a prefix to a GGC node makes the node a candidate to serve users behind that prefix. It does not guarantee that the GGC node will be selected as the best location to serve that prefix.

When Google have multiple paths available to serve a prefix, the "best" one is continuously re-calculated.

The calculation is based primarily on prefix-specificity, AS-path length and RTT. A number of other factors will also be considered, including current GGC loading, and the quality of the network paths between the GGC node and it's users.

Google rely on our GGC partners to make appropriate prefix announcements to the node(s) they host, and do not intervene in discussions about the propriety of individual advertisements.

What does it mean to have fast or autonomous switching "enabled" and "disabled" on the same interface ?

Look at the above snap ^

If you enable fast or autonomous switching on an interface, packets coming from any other interface on the router are fast-switched (or autonomous-switched) to that interface. If you enable same-interface fast or autonomous switching, packets whose source and destination address are the same are fast or autonomous switched. You can use same-interface fast or autonomous switching in cases where you have Frame Relay or Asynchronous Transfer Mode (ATM) WAN links configured as subinterfaces on the same main interface. Another situation is when you are using secondary networks on LAN interfaces, as during IP address migration. In order to enable same-interface fast switching, use the ip route-cache same-interface configuration command.

Fast Switching:-

Fast switching is an improvement over process switching. The first packet of a new session is copied to the interface processor buffer. The packet is then copied to the CxBus (or other backplane technology as appropriate to the platform) and sent to the switch processor. A check is made against other switching caches (for example, silicon or autonomous) for an existing entry.

Fast switching is then used because no entries exist within the more efficient caches. The packet header is copied and sent to the route processor, where the fast-switching cache resides. Assuming that an entry exists in the cache, the packet is encapsulated for fast switching and sent back to the switch processor. Then the packet is copied to the buffer on the outgoing interface processor, and ultimately it is sent out the destination interface.

Fast switching is on by default for lower-end routers like the4000/2500 series and may be used on higher-end routers as well. It is important to note that diagnostic processes sometimes require reverting to process switching. Fast-switched packets will not traverse the route processor, which provides the method by which packets are displayed during debugging. Fast switching may also be inappropriate when bringing traffic from high-speed interfaces to slower ones—this is one area where designers must understand not only the bandwidth potential of their links, but also the actual flow of traffic.

Fast switching guarantees that packets will be processed within16 processor cycles. Unlike process-switched packets, the router’s processor will not be interrupted to facilitate forwarding.

Autonomous Switching:-

Feature on Cisco routers that provides faster packet processing by allowing the ciscoBus to switch packets independently without interrupting the system processor.

Autonomous switching is comparable to fast switching. When a packet arrives on the interface processor, it checks the switching cache closest to it— the caches that reside on other processor boards. The packet is encapsulated for autonomous switching and sent back to the interface processor. The packet header is not sent to the route processor. Autonomous switching is available only on AGS+ and Cisco7000 series routers that have high-speed controller interface cards.

If you enable fast or autonomous switching on an interface, packets coming from any other interface on the router are fast-switched (or autonomous-switched) to that interface. If you enable same-interface fast or autonomous switching, packets whose source and destination address are the same are fast or autonomous switched.

You can use same-interface fast or autonomous switching in cases where you have Frame Relay or Asynchronous Transfer Mode (ATM) WAN links configured as subinterfaces on the same main interface. Another situation is when you are using secondary networks on LAN interfaces, as during IP address migration. In order to enable same-interface fast switching, you can use the ip route-cache same-interface command.

Deploying SEEDBOX using uTorrent on Ubuntu Server.

Tools to be Downloaded:
------------------------------------------------------------------------------------------
1. http://www.mollify.org/downloads.php
2. http://www.utorrent.com/downloads/linux
------------------------------------------------------------------------------------------
------------------------------------------------------------------------------------------

Install uTorrent Server 3.3

Step 1: Download latest uTorrent Server from here

Note: (You need to download uTorrent Server for 13.04, also works for Ubuntu 14.04)

Step 2: Extract uTorrent Files

Launch terminal and change directory to Downloads folder
```
cd Downloads/
```
Extract uTorrent files to the /opt directory
```
sudo tar xvzf utserver.tar.gz -C /opt/
```

Step 3: Set Permission

Set permission on uTorrent-server folder

sudo chmod -R 777 /opt/utorrent-server-alpha-v3_3/

Step 4: Set Symbolic link

Run the command to link uTorrent server to the /user/bin directory.

sudo ln -s /opt/utorrent-server-alpha-v3_3/utserver /usr/bin/utserver

Step 5: Start uTorrent

utserver -settingspath /opt/utorrent-server-alpha-v3_3/

Note: If you get an error about libssl.so package missing or see utserver not starting, run the command below to install it, then try starting it again.

sudo apt-get install libssl0.9.8:i386

Step 6: Log into uTorrent

Open Firefox and browse to the URL
```
localhost:8080/gui
```
The username is 'admin' and leave the password field empty.

Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP

D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

E1 - OSPF external type 1, E2 - OSPF external type 2

i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

ia - IS-IS inter area, * - candidate default, U - per-user static route

o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
