Configuring Static MAC Addresses

 

 

 

 

 

•MAC Address— Enter the static MAC address.

•Status—Select a status for this static MAC address:

-Permanent—When this status is selected, the static MAC address does not expire. Note, however, that if the switch is rebooted, the entry is not restored unless the Running Configuration file type was copied to the Startup Configuration file type. See Copying and Saving Configuration Files.

-Delete on Timeout—When this status is selected, the static MAC address is static but may expire due to inactivity. In this respect, it is treated like a dynamically learned MAC address. See the Dynamic Address Settings to set the aging period.

-Secure—When this status is selected, the MAC address is secured and is used in conjunction with the Port Security feature. When a MAC address is secured at a port, packets that originate from the MAC address can only be ingressed from the secured port. Otherwise, the packets are discarded. If port security is disabled on the port, the MAC address is deleted from the static MAC address list. When Port Security is enabled at a port, the port can support a maximum of 256 static and dynamic MAC addresses. (For more information, see Enabling Port Security).

STEP 4 Click Apply and then click Close. Your changes are saved to the Running Configuration.

NOTE To delete a static MAC address, select it in the table and click Delete.

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.
