The ethernet <slot/port> parameter displays the mstp protocol information for the specified
Ethernet interface.
TABLE 186 CLI display of MSTP information for the specified Ethernet interface
This field... Displays...
<slot/port> The MSTP protocol information for the specified ethernet interface.
NOTE: If the Ethernet interface is not added to any MSTP enabled
VLANs, the command displays the following message instead:
"No MSTP-configured VLANs for the port

MSTP (IEEE 802.1s) port parameters
Port Num The port number shown in a slot#/port# format.
Pri The configured priority of the port. The default is 128 or 0x80.
Port Path Cost The configured path cost on a link connected to this port.
P2P Mac Indicates if the point-to-point-mac parameter is configured to be a
point-to-point link:
•
T – The link is configured as a point-to-point link.
•
F – The link is not configured as a point-to-point link. This is the

states:
•
Forwarding
•
Discarding
•
Learning
•
Disabled
Refer to “Bridge port states” on page 363 and “Edge port and non-edge
port states” on page 364
