Viewing and Deleting Dynamic DNS Entries

The DNS Dynamic Entries table displays hostnames that have been learned by applications that use DNS lookup services. For example, if you ping a hostname, the DNS lookup service is invoked and an associated IP address is learned and added to the table.

The DNS Dynamic Entries table displays the following fields:

Hostname—Host name assigned to the IP address (or to an official hostname).

Total—Number of minutes the hostname has been reserved for this assignment.

Elapsed—Number of minutes that have elapsed since the hostname was assigned.

Type—Identifies the hostname as one of the following:

-IP Address—The assigned hostname is associated with an IP address.

-Canonical—The assigned hostname is an alias or nickname for a properly denoted (official) hostname. For example, www.google.com might be a hostname alias associated with the official hostname www.l.google.com.

Addresses—If the Type is IP, this field displays the IPv4 address or the IPv6 address that is associated with the hostname. If the Type is Canonical, this field displays the canonical hostname that the alias is associated with. A canonical DNS address might have more than one hostname alias associated with it.

To delete a dynamic entry, select it and click Delete. To delete all dynamic entries from the table, click Delete All Dynamic Entries.

SLM2008PTNA specifications

Cisco Systems SLM2008PTNA is a robust network switch designed specifically for small to medium-sized businesses. It operates with 8 Fast Ethernet ports, providing advanced features and best-in-class performance to enhance your network infrastructure. This model ensures seamless connectivity for multiple devices, making it an ideal choice for environments requiring reliable network communication.

One of the standout features of the SLM2008PTNA is its Layer 2 switching capabilities. This switch supports auto-negotiation, which allows each port to automatically detect the speed of the connected device and adjust accordingly. This ensures optimal performance and smooth operation across various connected devices. Additionally, the switch supports a non-blocking architecture, ensuring that bandwidth is not shared, which significantly enhances data transmission speed.

Power over Ethernet (PoE) is another key technology incorporated into the Cisco SLM2008PTNA. It simplifies the installation of network devices such as VoIP phones, security cameras, and wireless access points by supplying power through the Ethernet cable. This eliminates the need for separate power sources, reducing installation costs and increasing flexibility in device placement.

Moreover, the SLM2008PTNA comes equipped with advanced security features, such as port security and VLAN support. Port security allows network administrators to restrict access to the network based on MAC addresses, preventing unauthorized access and enhancing network security. The support for Virtual Local Area Networks (VLANs) enables the segmentation of the network into different logical networks, improving traffic management and security within each segment.

The switch is designed for easy management and monitoring, featuring a user-friendly web interface that simplifies configuration. This allows network administrators to quickly set up and manage the device without requiring extensive technical knowledge. Additionally, its compact design makes it suitable for desktop or rack-mount installation, maximizing space efficiency in network environments.

In conclusion, the Cisco Systems SLM2008PTNA is an essential component for small to medium-sized businesses looking to enhance their network performance. With its Layer 2 switching capabilities, Power over Ethernet support, advanced security features, and ease of management, this switch provides a well-rounded solution for modern networking needs, delivering reliable performance and scalability for growth.
