Class Map

 

 

 

 

 

Use the fields in the Match Criteria Configuration area to match packets to a class. Select the check box for each field to be used as a criterion for a class and enter data in the related field. You can have multiple match criteria in a class.

The match criteria fields that are available depend on whether the class map is an IPv4 or IPv6 class map.

Defining a Class Map

To configure a class map:

STEP 1 Select the class map from the Class Map Name list.

STEP 2 Configure the parameters (parameters that appear only for IPv4 or IPv6 class maps are noted):

•Match Every Packet—The match condition is true to all the parameters in a Layer 3 packet.

When selected, all Layer 3 packets will match the condition.

•Protocol—Use a Layer 3 or Layer 4 protocol match condition based on the value of the IP Protocol field in IPv4 packets or the Next Header field in IPv6 packets.

If you select this field, choose the protocol to match by keyword or enter a protocol ID.

-Select From List—Match the selected protocol: IP, ICMP, IPv6, ICMPv6, IGMP, TCP, UDP.

-Match to Value—Match a protocol that is not listed by name. Enter the protocol ID. The protocol ID is a standard value assigned by IANA. The range is a number from 0 to 255.

•Source IP Address or Source IPv6 Address—Requires a packet's source IP address to match the address listed here. Check the box and enter an IP address.

•Source IP Mask (IPv4 only)—The source IP address mask.

The mask for DiffServ is a network-style bit mask in IP dotted decimal format indicating which part(s) of the destination IP address to use for matching against packet content.

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.
