Forward delay | Spanning tree forward delay. | – |
| Interface List | ||
Interface Name | Interface configured to participate in the STP instance. | – |
Port ID | Logical interface identifier configured to participate in the STP instance. | – |
Designated Port ID | Port ID of the designated port for the LAN segment to which the interface is attached. | – |
Port Cost | Configured cost for the interface. | – |
State | STP port state. Forwarding (FWD), blocking (BLK), listening, learning, or disabled. | – |
Role | MSTP or RSTP port role. Designated (DESG), backup (BKUP), alternate (ALT), or root. | – |
Monitoring IGMP Snooping
Purpose
Use the monitoring functionality to view the IGMP Snooping page.
Action

Monitoring GVRP
Purpose
Use the monitoring functionality to view the GVRP page.
Action
To monitor GVRP select Monitor>Switching>GVRP in the J-Web user interface.
Meaning
