4. Specify the BPDU Flooding status for all ports or for individual ports. When this feature is
enabled, BPDU packets arriving at this port are flooded to other ports if STP is disabled.
5. Click Cancel
to cancel the configuration on the screen and reset the data on the screen to
the latest value of the switch
6. If
you make any configuration changes, click Apply to send the updated configuration to the
switch. Configuration changes occur immediately.
The following table describes the STP Status information
displayed on the screen.
Field Description
Bridge Identifier The bridge identifier for the CST. It is made up using the bridge priority and
the base MAC address of the bridge.
Time Since Topology Change The time in seconds since the topo
logy of the CST last changed.
Topology Change Count The number of times the topology has changed for the CST.
Topology Change The value of the topology change parameter for the switch indicating if a
topol
ogy change is in progress on any port assigned to the CST. The value is
either True or False.
Designated Root The bridge identifier of the root bridge. It is made up
from the bridge priority
and the base MAC address of the bridge.
Root Path Cost Path cost to the Designated Root for the CST.
Root Port Port to access the Designated Root for the CST.
Max Age (secs) Specifies the bridge maximum age for CST
. The value must be less than or
equal to (2 X Bridge Forward Delay) – 1 and greater than or equal to 2 X
(Bridge Hello Time +1).
Forward Delay (secs) Derived value of the Root Port Bridge Forward Delay parameter.
Hold TIme (secs) Minimum time between transmission of Configuration BPDUs.
CST Regional Root Priority and base MAC address of the CST Regional Root.
CST Path Cost Path Cost to the CST tree Regional Root.

Summary

Getting Started

Connecting the Switch to the Network

Details how to connect the switch to the network for remote management and IP configuration.

Configuring the Network Settings on the Administrative System

Web Access

Configuring System Information

IP Configuration

Configures network information for the management interface, including IP address, subnet mask, and gateway.

IPv6 Network Configuration

Configuring Switching Information

Ports

Allows viewing and monitoring of physical port information and configuration settings.

Link Aggregation Groups

VLANs

Divides a physical network into separate logical networks for administration, security, and management.

Voice VLAN

Configures voice VLAN settings to ensure quality of IP phone traffic by prioritizing it.

Spanning Tree Protocol

Provides a tree topology to eliminate loops in bridged networks, supporting STP, RSTP, and MSTP.

Forwarding Database

Configuring Routing

Configuring IP Settings

Enables routing globally and allows viewing packet information, including IP configuration.

Configuring VLAN Routing

Configures VLAN routing interfaces to enable traffic flow between different VLANs.

Configuring and Viewing Routes

Allows configuration of static and default routes and viewing learned routes in the routing table.

Configuring ARP

Associates Layer 2 MAC addresses with Layer 3 IPv4 addresses for network communication using ARP.

Configuring Quality of Service

Class of Service

Lets you configure switch queueing aspects and map packet priority to appropriate queues.

Differentiated Services (DiffServ)

Supports classifying traffic into streams and providing QoS treatment based on defined per-hop behaviors.

Managing Device Security

Management Security Settings

Configures login password, RADIUS, TACACS+, and authentication lists for secure management access.

Configuring Management Access

Manages HTTP/HTTPS access, Access Control Profiles, and Access Rules for secure network access.

Port Authentication

Enables and configures port access control using 802.1X authentication for device access.

Traffic Control

Configures MAC Filters, Storm Control, and Port Security to manage and limit network traffic.

Configuring Access Control Lists

Defines rules to authorize users and block unwanted access to network resources via ACLs.

Monitoring the System

Ports

System Logs

Maintenance

Reset

Provides options for device reboot and resetting system configuration to factory default values.
