Cisco Systems launched recently a Wireless access point targeting the Small to Midsize business. The Cisco AP 500 Access Point is easy to install and manage. The clustering technology with simplifies the deployment and of Cisco AP 500 AP by creating single point of administration for multiple Cisco AP 500 Access Points. Currently Cisco is offering one model AP 541.
The Cisco AP 500 comes with clustering technology, Gigabit Ethernet LAN interface for higher throughput, 802.11n compliance and dual band user selection for either 2.4 GHz or 5 GHz and more over it supports voice roaming.
Some of the features of Cisco AP 500 are as follows
Cisco AP 500 Series Wireless Access Points offer a range of features:
- Clustering Technology: Simplifies wireless deployments by creating a single point of administration for multiple access points. Clustering technology replicates a configuration, pushes it out to other access points, and continuously manages the frequency channels for each device, reducing network interface.
- Superior Performance: Gigabit Ethernet LAN interface for higher throughput. Wireless radio complies with 802.11n wireless technology, using MIMO technology to enhance network coverage, capacity, and throughput for data and multimedia applications, while allowing for backward compatibility with a, b, and g clients.
- Robust Security: Supports business-class security encryptions (WPA2, 802.1x supplicant) and authentication for client compatibility, MAC address authentication, client isolation, and rogue access point detection.
- Voice Roaming: Allowing for client fast roaming while maintaining good voice quality with 802.11i pre-authenticated standards.
- Power Options: Uses both standard AC power and Power-over-Ethernet (PoE), simplifying installations in locations such as drop ceilings where power outlets may not be accessible.

In my last article we know how to send a message to all telnet users in a Cisco Router or a Cisco Switch using “send” command. This command can also use to send a message any particular telnet users. It’s quite simple.
Long in to your Cisco Device and look for current telnet users, by using a “show users” command
Line User Host(s) Idle Location
1 vty 0 netmgr idle 00:00:49 10.0.0.5
2 vty 1 yasir idle 00:00:16 10.0.0.5
* 3 vty 2 yasir idle 00:00:00 10.0.0.7
Interface User Mode Idle Peer Address
If you want to send a message to vty session 1 then do as follows.
Enter message, end with CTRL/Z; abort with CTRL/C:
Dear User netmgr please log off as we need to change your password
Send message? [confirm]^Z

Recently a good friend of mine published an article which highlights on the some of the new features in ASP.Net 4.0 and Visual Studio 2010.
This article is worth reading, though I am not into ASP.Net or Visual Studio, I enjoyed the article.
The author of this article can be reached at email@example.com
Imagine you need to restart your Cisco Router or a Cisco Switch for some reason, but there are few telnet users logged into your Cisco device. There is a way to send a message to all active telnet users. By using a “send” command from your Cisco Router or a Cisco Switch you can send a message. To do so login to your Cisco Router or a Cisco Switch and type “send*”
ITKEAS01# send *
Once you enter “send*” in your Cisco Router or a Cisco Switch you will see the following prompt in your device
Enter message, end with CTRL/Z; abort with CTRL/C:
Then you can type your message followed by control Z to send the message to all tty lines.
This is test message
Please log out of router as we need to restart it^Z
Send message? [Confirm]
*** Message from tty1 to all terminals:
This is test message
Please log out of router as we need to restart it
NOTE: When you want to send the message use the CTRL/Z key sequence

First of all I would like to thanks Michael Morisy from ITKE for offering me a copy of “PM crash course for IT Professionals” also I am thankful to Jamie Adams from Cisco Press for her support all the time.
Since I was the Project Manager for our Data Center Expansion project, this book came to me as a great working manual to implement the project. I followed the methodology discussed by the author a management guru Rita Mulcahy (PMP) and I imbibed the methodology into my project which led to successful completion.
The book really met the objectives to assist the IT professionals to sharpen their project management skills. The best thing I like about the book is the way Rita explained the essentials of project management and this book can be read in a short span of time.
The “PM crash course for IT Professionals” is a fine book in which the author have refined the essentials of Project Management into concise points. The exercises, check lists, templates available in this book are quite beneficial especially to IT Professionals.
I would recommend the “PM crash course for IT Professionals” for IT professionals/ Project Manages who are looking an immediate impact on going projects as this book comes with lots of easy to use tools and processes followed by great ideas .
Netflow is an important tool and it has become an important factor especially when it comes to managing the network and vigilantly watching the bandwidth utilization. Solar Winds designed a free NetFlow confrigurator which is the easiest tool I have seen, the Solar winds NetFlow confrigurator is capable of configuring the NetFlow v5 via SNMP on supported Cisco® devices. The free NetFlow Confrigurator also facilitates setting up collectors for Cisco NetFlow data, specifying the ports on which the collectors are listening, and enabling monitoring of inbound and outbound (ingress/egress) traffic data per interface.
Here is a cool video from Solar Winds which demonstrates how to configure NetFlow in Cisco Devices.

In my last post we looked at how to fix the corrupted IOS in a Cisco 1250 Wireless Access Point, the other way of recovering the corrupted IOS is by again by using a solar winds TFTP server, but in this procedure the access point loads itself the image file from the TFTP server. In order do so follow the below mentioned steps.
Configure the PC with Solar Winds TFTP server with a class A Static IP Address range of 10.0.0.2 to 10.0.0.30.
Make sure that the PC with the solar winds TFTF server contains the Cisco 1250 Wireless Access Point IOS image file (such as c1250-k9w7-tar.124-21a.JA1 in the Solar Winds TFTP server folder) and the TFTP server is activated.
Rename the Cisco 1250 Wireless Access Point IOS image file in the solar winds TFTP server folder to the default image name –c1250-k9w7-tar.default for a Cisco 1250 Wireless Access Point.
Connect the PC with solar winds TFTF server to the Cisco 1250 Access point with a Category 6or Cat5 Ethernet cable (straight cable).
Disconnect power from the Cisco 1250 Access point.
Press and hold the MODE button while you reconnect power to the Cisco 1250 Access point.
Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds), and release the MODE button until the console indicates
Button is pressed; wait for button to be released
Once you release the button you will see the Cisco 1250 Access Point starts downloading the default IOS image from Solar wind TFTP sever as shown below
Wait until the Cisco 1250 access point reboots as indicated by all LEDs turning green followed by the Status LED blinking green.
After the Cisco 1250 access point reboots, reconfigure the access point using the Command Line Interface (CLI) or GUI.
Also check demonstrated video to recover the IOS in Cisco 1250 Access Point.
