Max Age
: indicates the maximum age time of information
transmitted by the switch when it is the Root Bridge. This
delay is only used when STP protocol is being used.
Allowed values are integer numbers from 6 to 40 seconds,
and the Max Age field depends on the Forward Delay as
follows:
𝑴𝒂𝒙 𝑨𝒈𝒆 ≤ 𝟐 ∙ (𝑭𝒐𝒓𝒘𝒂𝒓𝒅 𝑫𝒆𝒍𝒂𝒚 − 𝟏)
Maximum Hop Count
: indicates the initial value of
remaining bridges for MSTI instances information
generation at the boundary of an MSTI region. Thus, this
value defines how many bridges can belong to a given
region, as it limits the number of bridges that Root Bridge
can distribute BPDU information to. This information is
only used when MSTP protocol is being used. Allowed
values are integer numbers from 6 to 40 hops (bridges);
Transmit Hold Count
: indicates maximum BPDU packets
that can be sent per second at the ports allowed to
participate in the Spanning Tree protocol network.
Allowed values are integer numbers from 1 to 10 BPDU
packets per second.

Advanced Settings
Edge Port BPDU Filtering
: indicates if Edge ports
(explicitly configured as Edge ports in the CIST Ports menu)
will transmit and receive BPDU packets. Checkbox
selected means that Edge ports will not receive nor
transmit BPDU data, and checkbox empty means that
Edge Ports could receive and transmit BPDU information;
Edge Port BPDU Guard
: indicates if Edge ports (explicitly
configured as Edge ports in the CIST Ports menu) will
change its state to Trunk port automatically when a BPDU
packet is received. Checkbox selected means that Edge
ports will change its state automatically to Trunk when a
BPDU packet is received at the port, and checkbox empty
means that ports will not change its Edge state;
Port Error Recovery
: indicates if a port in Error state
(which will be disabled by the protocol) will be enabled
automatically after a given time. Checkbox selected
means that ports in error state will wait until the Port Error
Recovery Timeout expires to be enabled, and checkbox
empty means that port will not be activated automatically
after it becomes in Error state;
Port Error Recovery Timeout
: indicates timeout to be
applied in the Port Error Recovery function. Allowed values
are integer numbers from 30 to 86,400 seconds.
