1.The sname field in a DHCP or BOOTP reply.

2.The TFTP server name (option 66) field in a DHCP reply.

3.The TFTP server address (option 150) field in a DHCP reply.

4.The siaddr field of a DHCP or BOOTP reply.

If only the sname or option 66 values are returned to the switch, a DNS server is needed to resolve the IP address of the TFTP server. After an IP address is assigned to the switch, if a hostname is not already assigned, Auto Configuration sends a DNS request for the corresponding hostname.

Alternate TFTP Server and File Name

On the DHCP Auto Configuration page, you can configure an alternate TFTP server and file name to be used when the server or file name provided by the DHCP server cannot be located. The following procedure is followed:

1.The switch sends unicast messages to the TFTP server identified through DHCP, if provided.

2.If the DHCP information is not provided or the server or file name cannot be found, then the server uses the alternate information, if configured.

3.If the alternate information is not configured or the server or file name cannot be found, the switch sends broadcast TFTP requests for the file name in the DHCP message, if given. Otherwise, the switch enters default network configuration mode process described in the Default Network Configuration File section.

Configuration File Download Details

The switch first attempts to download a host-specific configuration file. If this is not possible, it downloads the configuration file <hostname>.cfg if Default Network Configuration Mode is enabled.

Host-specific Configuration File

The switch attempts to download the host specific configuration file whose name is specified as the boot file name in the reply from a DHCP/BOOTP server, or is configured as the Backup Configuration File for DHCP Auto Configuration. The switch makes three unicast TFTP requests for the specified boot file. If the unicast attempts fail, or if a TFTP server address was not provided, the switch makes three broadcast requests to any available TFTP server for the specified boot file. When the switch gets the configuration file, the configuration is validated for errors. If the validation is successful, the switch copies the configuration to the Startup Configuration file type, stores the configuration file name in non-volatile memory, and reboots the unit.

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.
