Configuring the Switch
3-84
Web – Click Spanning Tree, STA, Port Information or STA Trunk Information.
CLI – This example shows the STA attributes for port 5.
Configuring Interface Settings
You can configure RSTP attributes for specific interfaces, including port priority, path
cost, link type, and edge port. You may use a different priority or path cost for ports
of the same media type to indicate the preferred path, link type to indicate a
point-to-point connection or shared-media connection, and edge port to indicate if
the attached device can support fast forwarding.
Command Attributes
The following attributes are read-only and cannot be changed:
• STA State – Displays current state of this port within the Spanning Tree.
(See “Displaying Interface Settings” on page 3-81 for additional information.)
- Discarding - Port receives STA configuration messages but does not forward
packets.
- Learning - Port has transmitted configuration messages 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.
