Configuring the Switch

VLAN ID  VLAN to assign to this selected MST instance.. (Range: 1-4093)

Instance ID  Instance identifier of this spanning tree.. (Default: 0)

Included VLANs  VLANs assigned this instance..

Bridge Priority  The priority of a spanning tree instance.. (Range: 0-61440 in steps of 4096; Options: 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672, 32768, 36864, 40960, 45056, 49152, 53248, 57344, 61440; Default: 32768)

Designated Root Bridge ID  The bridge priority and MAC address of the device through which this port must communicate to reach the root of the Spanning Tree..

Root Port  The port priority and number of the port on the designated bridging device through which this switch must communicate with the root of the Spanning Tree..

Root Path Cost  The contribution of this port to the path cost of paths towards the spanning tree root which include this port..

Bridge ID  The bridge priority and MAC address of the device through which this port must communicate to reach the root of the Spanning Tree..

Remaining Hops  The remaining number of hop counts for the MST instance..

Modify the required attributes for MSTP Instance Settings.. Click Save Settings to save the changes..

Spanning Tree > MSTP Interface Settings

QoS > MSTP Interface Settings

Instance ID  Instance identifier to configure.. Select the required MST instance to display the current spanning tree values.. (Range: 0-4094; Default: 0)

Port  Displays the port number..

State  Shows if STA has been enabled on this interface..

Status  Displays current state of this port within the Spanning Tree:

•Discarding  Port receives STA configuration messages, but does not forward packets..

•Learning  Porthastransmittedconfigurationmessages for an interval set by the Forward Delay parameter without receiving contradictory information.. Port address table is cleared, and the port begins learning addresses..

•Forwarding  Port forwards packets, and continues learning addresses..

The rules defining port status are:

•A port on a network segment with no other STA compliant bridging device is always forwarding..

•If two ports of a switch are connected to the same segment and there is no other STA device attached to this segment, the port with the smaller ID forwards packets and the other is discarding..

•All ports are discarding when the switch is booted, then some of them change state to learning, and then to forwarding..

Role  Roles are assigned according to whether the port is part of the active topology connecting the bridge to the root bridge (i..e.., root port), connecting a LAN through the bridge to the root bridge (i..e.., designated port), or is the MSTI regional root (i..e.., master port); or is an alternate or backup port that may provide connectivity if other bridges, bridge ports, or LANs fail or are removed.. The role is set to disabled (i..e.., disabled port) if a port has no role within the spanning tree..

Forward Transitions  The number of times this port has transitioned from the Learning state to the Forwarding state..

Operational Edge Port  This parameter is initialized to the setting for Admin Edge Port in STA Port Configuration (i..e.., true or false), but will be set to false if a BPDU is received, indicating that another bridge is attached to this port..

Click the Detail button to configure Protocol Migration Test and Administrative Link Type.. Use the check box and drop-down menu provided to enable and select the mode, then click Apply..

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.
