Configuring the Switch

Ingress filtering  Determines how to process frames tagged for VLANs for which the ingress port is not a member.. (Default: Disabled)

Ingress filtering only affects tagged frames..

If ingress filtering is disabled and a port receives frames tagged for VLANs for which it is not a member, these frames will be flooded to all other ports (except for those VLANs explicitly forbidden on this port)..

If ingress filtering is enabled and a port receives frames tagged for VLANs for which it is not a member, these frames will be discarded..

Ingress filtering does not affect VLAN independent BPDU frames, such as GVRP or STP.. However, they do affect VLAN dependent BPDU frames, such as GMRP..

Fill in the required settings for each interface, then click Save Changes..

VLAN Management > Ports to VLAN

Use the Ports to VLAN screen to configure port members for the selected VLAN index.. Assign ports as tagged if they are connected to 802..1Q VLAN compliant devices, or untagged they are not connected to any VLAN-aware devices..

VLAN Management > Ports to VLAN

Switch Port Mode  Indicates VLAN membership mode for an interface.. (Default: Access)

Access  Is the default setting for all ports.. The port is a member of a single, untagged VLAN..

Trunk  Specifies a port as an end-point for a VLAN trunk.. A trunk is a direct link between two switches, so the port transmits tagged frames that identify the source VLAN.. Note that frames belonging to the port’s default VLAN (that is, associated with the PVID) are transmitted as untagged frames.. If the PVID is associated with a VLAN ID other than 1, then the frames are tagged..

General  Specifies a hybrid VLAN interface.. The port may transmit tagged or untagged frames..

Membership  Select VLAN membership for each interface by selecting the appropriate option for a port or LAG:

Excluded  The interface is forbidden from joining the VLAN..

Untagged  The interface is a member of the VLAN.. All packets transmitted by the port will be untagged, that is, not carry a tag and therefore not carry VLAN or CoS information.. Note that an interface must be assigned to at least one group as an untagged port..

Tagged  The interface is a member of the VLAN.. All packets transmitted by the port will be tagged, that is, carry a tag and therefore carry VLAN or CoS information..

VLAN Management > VLAN to Ports

VLAN Management > VLAN to Ports

Use the VLAN to Ports screen to assign VLAN groups to the selected interface..

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.
