Actual point-to-
point (read only)
The “Actual point-to-point” condition
is
true
if this port has a full duplex
connection to an STP device,
otherwise it is
false
(e.g. if a hub is
connected).
The point-to-point connection
makes a direct connection between
2 RSTP devices. The direct,
decentralized communication
between the two bridges results in a
short reconfiguration time.
This condition applies to all MSTIs.
true
,
false
is determined from
duplex mode:
FDX:
true
HDX:
false
Received bridge
ID (read only)
Displays the remote bridge ID from
which this port last received an STP-
BPDU.
In the stable condition (no topology
change), this is usually the
designated bridge ID, as only its port
has the role “designated” and thus
sends BPDUs.

mm mm mm mm mm

Received path
costs (read only)
Displays the path costs of the
remote bridge from its root port to
the CIST root bridge.
0-200,000,000
-
Received port
ID (read only)
Displays the port ID at the remote
bridge from which this port last
received an STP-BPDU.
In the stable condition (no topology
change), this is usually the
designated port of the designated
bridge, as only its port sends
BPDUs.
Port ID,
format pn nn,
with p: port priority /
16,
nnn: port No., (both
hexadecimal)
