– Disable: the RSTP function is not activated
– 802.1w: the RSTP function is activated globally and operates according to standard
802.1w
– Large Tree Support: the “Large Tree Support” option makes the ring topology suitable
for 28 switches along the relevant path if RSTP is used. The “Large Tree Support” op-
tion could provide an RSTP ring topology with up to 57 devices.
– Fast Ring Detection: this function speeds up switch-over to a redundant path in the
event of an error and provides easy diagnostics. RSTP fast ring detection provides
each ring with an ID. This ID is made known to each switch in the relevant ring. A switch
can belong to several different rings at the same time.
– Bridge Priority: the bridge and backup roots can be specified via “Bridge Priority”. Only
multiples of 4096 are permitted. The value will be rounded automatically to the next
multiple of 4096. Once you have clicked on “Apply&Save”, the initialization mechanism
is started (default value: 32768).
– Bridge Hello Time: specifies the time interval within which the root bridge regularly re-
ports to the other switches via BPDU.
– Bridge Forward Delay: the bridge forward delay value indicates how long the switch is
to wait for the port state in STP mode to change from “Discarding” to “Listening” and
from “Listening” to “Learning” (2 x forward delay).
– Bridge Max Age: the parameter is set by the root switch and used by all switches in the
ring. The parameter is sent to make sure that each switch in the network has a constant
value, against which the age of the saved configuration is tested.
Clicking on the “RSTP Port Configuration” button takes you to the “RSTP Port Configuration”
pop-up.
Clicking on the “RSTP Port Configuration Table” button takes you to the “RSTP Port Config-
uration Table” pop-up (see page 47).
Clicking on the “RSTP Diagnostic” button opens the “RSTP Diagnostic” page as a pop-up
(see page 52).
Media Redundancy Protocol (MRP)
MRP device mode:
- Disable: the MRP function is not activated
- Client: the MRP function is activated and the switch is the client
- Manager: the MRP function is activated and the switch is the ring manager
Ring Port 1: select the first MRP ring port here
Ring Port 2: select the second MRP ring port here
The functions below are only available if “802.1w” is activated.
The manager function is only available for the 2200/2300 versions provided that the SD
card is inserted and has a MRP master license (MRM) (see “Ordering data” on page 85).
