NOTE: Default domain names may be learned from reply messages from a DHCP server. These names display in the Default Domain Name List.

STEP 4 Click Apply. Your changes are saved to the Running Configuration.

Adding DNS Servers

The DNS Servers Table lists the configured servers.

To add a DNS server:

STEP 1 Click Add.

STEP 2 Specify the DNS server IPv4 or IPv6 address.

STEP 3 Click Apply and then click Close. Your changes are saved to the Running

Configuration and the server appears in the DNS Servers Table.

Hostname Mapping

Use the Host Mapping page to view and configure associations between hostnames and IP addresses. You can statically associate a hostname with an IP address. You can also view hostnames that have been learned dynamically through applications that use the DNS lookup service.

NOTE If you configure a static hostname and IP address, and that same hostname IP address mapping is later learned from DNS, the entry becomes dynamic and it is no longer saved as a static entry in the the Running Configuration.

Configuring Static DNS Mappings

The Host Mapping Table lists hostnames that are statically assigned to IP addresses on the switch. To configure a static hostname mapping:

STEP 1 Click IP Configuration > Domain Name System > Host Mapping in the navigation window.

STEP 2 Click Add.

STEP 3 Enter a hostname from 1–255 alphanumeric characters. The hostname must begin with a letter.

STEP 4 Enter an IPv4 or IPv6 address to be associated with the hostname.

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.
