Configuring the Switch

Operation Mode  Allows single or multiple hosts (clients) to connect to an 802..1X-authorized port.. (Options: Single- Host, Multi-Host; Default: Single-Host)

Maximum Count (1-1024)  The maximum number of hosts that can connect to a port when the Multi-Host operation mode is selected.. The default value is 5..

Mode  Sets the authentication mode to one of the following options:

•Auto  Requires a dot1x-aware client to be authorized by the authentication server.. Clients that are not dot1x- aware will be denied access..

•Force-Authorized Forces the port to grant access to all clients, either dot1x-aware or otherwise.. (This is the default setting..)

•Force-Unauthorized Forces the port to deny access to all clients, either dot1x-aware or otherwise..

Authorized  Indicates the current status of the port:

•Yes  A connected client is authorized..

•No  No connected clients are authorized..

•Blank  Displays nothing when there is no connection on a port..

Supplicant  Indicates the MAC address of a connected client..

Modify the parameters required using the drop-down menus and fields provided for each port, then click Detail to configure the 802..1X settings for that port..

Security > 802..1x Port Setting Detail

The 802..1x Port Settings screen allows configuration of the following parameters:

Maximum Request  Sets the maximum number of times the switch port will retransmit an EAP request packet to the client before it times out the authentication session.. (Range: 1-10; Default 2)

Quiet Period  Sets the time that a switch port waits after the Max Request Count has been exceeded before attempting to acquire a new client.. (Range: 1-65535 seconds; Default: 60 seconds)

Reauthentication Period  Sets the time period after which a connected client must be re-authenticated.. (Range: 1-65535 seconds; Default: 3600 seconds)

Transmit Period  Sets the time period during an authentication session that the Switch waits before re- transmitting an EAP packet.. (Range: 1-65535; Default: 30 seconds)

Click Save Settings to apply the changes..

Security > Ports Security

Port security is a feature that allows you to configure a switch port with one or more device MAC addresses that are authorized to access the network through that port.. When port security is enabled on a port, the Switch stops learning new MAC addresses on the specified port when it has reached a configured maximum number.. Only incoming traffic with source addresses already stored in the dynamic or static address table will be accepted as authorized to access the network through that port.. If a device with an unauthorized MAC address attempts to use the switch port, the intrusion will be detected and the Switch can automatically take action by disabling the port and sending a trap message..

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.
