Chapter 5

Configuring the Switch

To use port security, specify a maximum number of addresses to allow on the port and then let the Switch dynamically learn the <source MAC address, VLAN> pair for frames received on the port.. When the port has reached the maximum number of MAC addresses the selected port will stop learning.. The MAC addresses already in the address table will be retained and will not age out.. Any other device that attempts to use the port will be prevented from accessing the Switch..

Set the action to take when an invalid address is detected on a port, mark the checkbox in the Status column to enable security for a port, set the maximum number of MAC addresses allowed on a port.. Click Save Changes to save the changes..

Security > HTTPS Settings

You can configure the Switch to enable the Secure Hypertext Transfer Protocol (HTTPS) over the Secure Socket Layer (SSL), providing secure access (that is, an encrypted connection) to the Switch’s web interface..

Security > HTTPS Settings

To enable HTTPS, check the HTTPS Status checkbox and specify the port number..

Click Save Settings to save the changes..

Security > Management ACL

Security > Management ACL

You can create a list of up to 16 IP addresses or IP address groups that are allowed access to the Switch through the web interface, SNMP, or Telnet..

The management interfaces are open to all IP addresses by default.. Once you add an entry to a filter list, access to that interface is restricted to the specified addresses.. If anyone tries to access a management interface on the Switch from an invalid address, the Switch will reject the connection, enter an event message in the system log, and send a trap message to the trap manager..

IP addresses can be configured for SNMP, web and Telnet access.. Each of these groups can include up to five different sets of addresses, either individual addresses or address ranges.. When entering addresses for the same group (i..e.., SNMP, web or Telnet), the Switch will not accept overlapping address ranges.. When entering addresses for different groups, the Switch will accept overlapping address ranges..

You cannot delete an individual address from a specified range.. You must delete the entire range, and reenter the addresses.. You can delete an address range just by specifying the start address, or by specifying both the start address and end address..

SRW248G4P specifications

Cisco Systems SRW248G4P is a high-performance Layer 2 switch designed specifically for small to medium-sized businesses that require robust networking solutions. This switch supports Power over Ethernet (PoE), providing a highly flexible option for powering devices such as IP phones, wireless access points, and surveillance cameras.

One of the standout features of the SRW248G4P is its 48 10/100 Ethernet ports, which ensure ample connectivity for various networked devices. Additionally, it offers four Gigabit Ethernet uplink ports, allowing for seamless integration with existing network infrastructure and facilitating high-speed data transfer. The combination of these ports enables businesses to expand their network capabilities as needed without the immediate requirement for added devices.

The SRW248G4P comes equipped with advanced Layer 2 switching capabilities, including VLAN support, which enables the segmentation of network traffic for improved performance and security. It also supports Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP), which help prevent network loops and ensure redundancy. With features like Link Aggregation Control Protocol (LACP), multiple physical connections can be combined into a single logical link, enhancing bandwidth and providing failover capabilities.

Another critical attribute of the Cisco SRW248G4P is its user-friendly management interface. The switch can be managed through a web-based interface, allowing IT administrators to configure settings, monitor performance, and troubleshoot issues with ease. Additionally, it supports SNMP (Simple Network Management Protocol) for integration with network management systems, further simplifying monitoring tasks.

Power over Ethernet functionality is a significant advantage of the SRW248G4P, providing up to 15.4 watts per port. This capability simplifies installation and reduces the clutter of power cords and outlets. Organizations can deploy PoE-enabled devices in locations that lack power sources, thus enhancing overall flexibility in network design.

In summary, the Cisco Systems SRW248G4P is a feature-rich switch tailored for small to medium-sized enterprises. Its blend of performance, management capabilities, and advanced features like PoE makes it a valuable asset in any organization's networking setup. By ensuring reliable connectivity and ease of management, businesses can focus more on growth and their core objectives rather than worrying about network complexities.
