Switch’s Spanning Tree Configuration

and Identity of VLANs Configured in the

Switch for the IST Instance

Lists the switch’s MSTP root data for

connectivity with other regions and STP

or RSTP devices.

Internal Spanning Tree Data (IST

Instance) for the region in which the

Switch Operates

For

Edge

(

admin-edge-port

operation disabled)

indicates the port is configured for connecting to a

LAN segment that includes a bridge or switch.

Yes

indicates the port is configured for a host (end node)

link. Refer to the

admin-edge-port

description under

“Configuring MSTP Per-Port Parameters” on page 4-

Yes

means the switch is operating the

port as if it is connected to switch, bridge,

or end node (but

not

a hub).

Identifies the overall spanning-tree root

for the network.

Identifies the spanning-tree root for the

IST Instance for the region.

Identifies the ports with BPDU protection

and BPDU filtering enabled.
