Specifies the switch Maximum Age Time. The Maximum Age Time, Modifying STP Global Parameters

Page 242 highlights

www.dell.com | support.dell.com • Max Age (6-40)-Specifies the switch Maximum Age Time. The Maximum Age Time indicates the amount of time in seconds a bridge waits before sending configuration messages. The default maximum age time is 20 seconds. • Forward Delay (4-30)-Specifies the switch forward delay time. The Forward Delay Time indicates the amount of time in seconds a bridge remains in a listening and learning state before forwarding packets. The default is 15 seconds. • Bridge ID-Identifies the Bridge priority and MAC address. • Root Bridge ID-Identifies the Root Bridge priority and MAC address. • Root Port-Indicates the port number that offers the lowest cost path from this bridge to the Root Bridge. It is significant when the Bridge is not the Root. The default is zero. • Root Path Cost-The cost of the path from this bridge to the root. • Topology Changes Counts-Specifies the total amount of STP state changes that have occurred. • Last Topology Change-Indicates the amount of time that has elapsed since the bridge was initialized or reset, and the last topographic change occurred. The time is displayed in a day hour minute second format, for example, 2 days 5 hours 10 minutes and 4 seconds. Defining STP Global Parameters: 1 Open the Spanning Tree Global Parameters page. 2 Select Enable in the Spanning Tree State field. 3 Select the Classic STP in the STP Operation Mode field. 4 Click Apply Changes. STP is enabled on the device. Modifying STP Global Parameters: 1 Open the Spanning Tree Global Parameters page. 2 Define the STP Operation Mode, Bridge Priority, Hello Time (Sec), Max Age (Sec), and the Forward Delay (Sec) fields. 3 Click Apply Changes. The STP parameters are modified, and the device is updated. Defining STP Global Parameters Using CLI Commands The following table summarizes the equivalent CLI commands for defining STP Global Parameters as displayed in the Spanning Tree Global Settings page. 242 Configuring Switch Infor mation

Max Age (6-40
)—Specifies the switch Maximum Age Time. The Maximum Age Time
indicates the amount of time in seconds a bridge waits before sending configuration
messages. The default maximum age time is 20 seconds.

—Specifies the switch forward delay time. The Forward Delay
Time indicates the amount of time in seconds a bridge remains in a listening and
learning state before forwarding packets. The default is 15 seconds.
Bridge ID
—Identifies the Bridge priority and MAC address.
Root Bridge ID
—Identifies the Root Bridge priority and MAC address.
Root Port
—Indicates the port number that offers the lowest cost path from this
bridge to the Root Bridge. It is significant when the Bridge is not the Root. The default
is zero.
Root Path Cost
—The cost of the path from this bridge to the root.
Topology Changes Counts
—Specifies the total amount of STP state changes that
have occurred.
Last Topology Change
—Indicates the amount of time that has elapsed since the
bridge was initialized or reset, and the last topographic change occurred. The time is
displayed in a day hour minute second format, for example, 2 days 5 hours 10 minutes
and 4 seconds.
