3D sound clips

Got this link from my friend Rendo. Virtual Barber shop 3D sound in youtube.

You can see this link below:

Watch now

This clip has 3D sound like real life especially when used earphone. Why earphone? Because earphone will make sounds pretty clear which side he moved left or right.

In the beginning he will put the bag inside my head and then put it off. In the middle he started to cut my hair using scissors from the right to left. He gave me surprise when started to cut my hair. I feel his knife too closed from my ears. At the end of this clip, he whispered a word to my left ears, make me frightened.

Awesome

Why VLAN id 1 doesn’t work between Catalyst to another

By default Cisco Catalyst send frame with vlan-id 1 which is native vlan itself.

Therefore, when you have another devices which is connected using vlan id 1 with catalyst, it will not work until you move management vlan in catalyst to another vlan other than vlan id 1.

So, its not nice to use vlan with id 1 when you have tag on that vlan.

My Old Turtle

When i was kid, 10 years old, my mother gave me 6 turtles. Some of them died and leave. Only remain 1 turtle till now. This turtle still is alive and healthy. Since 4 years ago, I took it to Capital Jakarta and become new “life” member in my home. Now, this turtle is 21 years old… Amazing. His body size is 17cm x 14cm length.

Embarrassing moment

Embarrassing moment. Ngisin2i.

Watch now

In the end of this clip, he just said “That was Indonesia justice”.

Please deh……

Integrated Traceroute Monitor

Advance Traceroute monitoring available on Junos 8.0 and above.

With this feature, you can detect delay and latency parameter on specifics destination hop by hop. It just likes a ping plotter.

Displays live monitoring of each hop in the route packets take to a specified network host. Use traceroute monitor as a debugging tool to locate points of failure in a network.

Command introduced in JUNOS Release 8.0

Syntax:

traceroute monitor host

<count value>

<inet | inet 6>

<interval seconds>

<no resolve>

<size value>

<source source-address> 

<summary>

The sample result:

(Sorry, i renamed all ip address with A.B.C.D for confidential purposes)

Host: Hostname or IP address of the router at each hop.

Loss%: Percent of packet loss. The number of ping responses divided by the number of ping requests, specified as a percentage.Snt: Number of ping requests sent to the router at this hop.

Last: Most recent round-trip time, in milliseconds, to therouter at this hop.

Avg: Average round-trip time, in milliseconds, to the router at this hop.

Best: Shortest round-trip time, in milliseconds, to the router at this hop.

Wrst: Longest round-trip time, in milliseconds, to the router at this hop.

StDev: Standard deviation of round-trip times, in milliseconds, to the router at this hop.

Optical Diagnostics

Since Junos 8.2, Juniper has introduced new feature called with optical diagnostics . Several SFP PICs now support optical diagnostic which is indicated power transmit and receive. This feature really helps me when troubleshooting physical layer issues. This feature first introduced in Junos 7.x version but limited only for 10GigE and OC-768 PICs, thus, only supported on M320 and T series platforms. Now, all M-series router are supported.

Cli: optimus@prime> show interfaces diagnostics optics <GigE interface>

The sample result is:

Result shown below are indicated there are physical problems, there are active
alarms.

You have to check technical documentation and see power requirement for each
SFP.
