Packet Capture

 

 

 

 

 

A Microsoft Windows computer running the Wireshark tool allows you to display,

 

log, and analyze captured traffic. The remote packet capture facility is a standard

 

feature of the Wireshark tool for Windows. Linux version does not work with the

 

WAP device.

 

When remote capture mode is in use, the WAP device does not store any captured

 

data locally in its file system.

 

If a firewall is installed between the Wireshark computer and the WAP device, the

 

traffic for these ports must be allowed to pass through the firewall. The firewall

 

must also be configured to allow the Wireshark computer to initiate a TCP

 

connection to the WAP device.

 

To initiate a remote capture on a WAP device:

 

 

STEP 1

Click Administration > Packet Capture.

STEP 2

Enable Promiscuous Capture.

STEP 3

For the Packet Capture Method, select Remote.

STEP 4

For the Remote Capture Port, use the default port (2002), or if you are using a

 

port other than the default, enter the desired port number used for connecting

 

Wireshark to the WAP device. The port range is from 1025 to 65530.

STEP 5

If you want to save the settings for use at another time, click Save. (The selection

 

of Remote as the Packet Capture Method is not saved, however.)

STEP 6

Click Start Capture.

 

 

 

To initiate the Wireshark network analyzer tool for Microsoft Windows:

 

 

STEP 1

On the same computer, initiate the Wireshark tool.

STEP 2

In the menu, select Capture > Options. A popup window appears.

STEP 3

At Interface, select Remote. A popup window appears.

STEP 4

At Host, enter the IP address of the WAP device.

STEP 5

At Port, enter the port number of the WAP. For example, enter 2002 if you used the

 

default, or enter the port number if you used a port other than the default.

STEP 6

Click OK.

WAP121, WAP321 specifications

Cisco Systems has long been recognized for its innovation in networking technologies, and the Cisco WAP321 and WAP121 access points are prime examples of its commitment to delivering reliable, high-performance wireless networking solutions for small and medium-sized businesses. These devices offer a robust set of features designed to meet the requirements of modern wireless networking while ensuring ease of use and deployment.

The Cisco WAP321 is a dual-band access point that operates in both the 2.4 GHz and 5 GHz frequency bands, providing flexibility and improved performance in crowded environments. With support for the 802.11n Wi-Fi standard, it boasts a combined data rate of up to 450 Mbps, enabling high-speed connections for multiple users simultaneously. The WAP321 also includes advanced features such as multiple SSIDs and VLAN support, allowing businesses to segment their networks for enhanced security and management control.

One of the standout characteristics of the WAP321 is its ability to act as a lightweight access point, meaning it can be managed through a Cisco Wireless LAN Controller (WLC) for larger deployments. This capability allows for centralized management of multiple access points, making it easier for IT administrators to deploy, configure, and monitor their network infrastructure.

On the other hand, the Cisco WAP121 is designed for those requiring a simpler, more cost-effective solution. This single-band access point also operates on the 2.4 GHz band but still provides robust performance with wireless speeds reaching up to 300 Mbps. It is ideal for small businesses looking to develop or expand their wireless networks without the complexities associated with more advanced systems.

Both models feature Power over Ethernet (PoE) capability, enabling them to receive power through the Ethernet cable, which simplifies installation and reduces the need for additional power outlets. Additionally, they support advanced security protocols, including WPA/WPA2 encryption, ensuring that sensitive data transmitted over the network remains protected from unauthorized access.

The ease of setup and user-friendly management interfaces of both the WAP321 and WAP121 make them appealing options for businesses lacking extensive IT resources. With features aimed at enhancing both performance and security, these access points represent powerful tools for achieving reliable wireless connectivity in a business environment. Whether organizations opt for the WAP321 for its extensive capabilities or the WAP121 for its simplicity, both access points reflect Cisco's dedication to meeting diverse networking needs.
