STP status on Switch RSTP on/off at this port.
Switch STP off when connecting a
terminal device in order to avoid
unnecessary waiting times. See
also „Fast reconfiguration“.

Priority Enter the first byte of the port identi-
fier. See also „Port Identifier“.
16 < n*16< 240 128
Admin Path
Cost
Enter the path costs to indicate pref-
erence for redundant paths. If the
value is “0”, the Switch automatical-
ly calculates the path costs
depending on the transmission rate.
See also „Bridge parameters“.
0 - 200 000 000 0
Admin Edge
Port
Enter whether a terminal device
(true) or an RSTP switch (false) is to
be connected at this port. During re-
configuration, the edge port at a ter-
minal device can switch to
forwarding within 3 seconds.
See also „Port roles“.
true, false false
Oper Edge Port Shows whether an RSTP Switch is
connected at this port. Independent-
ly of the value set under “Admin
Edge Port”, the Switch detects a
connected RSTP switch. Then it
sets Edge Port = false.)
See also „Port roles“.
true, false -
Oper Point-
ToPoint
Shows whether at this port the con-
nection between two RSTP Switch-
es is a half-duplex connection (true)
or not (false). (The point-to-point
connection is a direct connection
between two RSTP Switches. The
direct, decentralized communication
between the two Switches results in
a fast reconfiguration time.)
true, false auto

FDX = true
HDX = false)
Designated

Display of the bridge identifier of the
designated root Switch for this port.
