DGS-1210 Series Ethernet Managed Switch CLI Reference Guide
42
forwarding packets to the specified port list. Port cost can be set
automatically or as a metric value. The default value is auto.
•
auto
– Automatically sets the speed for forwarding packets
to the specified port(s) in the list for optimal efficiency.
Default port cost:10Mbps port = 2000000. 100Mbps port =
200000. Gigabit port = 20000. Port-channel = 20000.
•
<value 1-200000000>
- Defines a value between 1 and
200000000 to determine the external cost. The lower the
number, the greater the probability the port will be chosen to
forward packets.
edge [auto | true | false]
–
true
DGSignates the port as an edge port.
Edge ports cannot create loops, however an edge port can lose
edge port status if a topology change creates a potential for a loop.
An edge port normally should not receive BPDU packets. If a BPDU
packet is received it automatically loses edge port status.
false
indicates that the port does not have edge port status. The default
setting for this parameter is false.
hellotime <value 1-2> –
The time interval between transmission of
configuration messages by the DGSignated port, to other devices on
the bridged LAN, thus stating that the Switch is still functioning. The
user may choose a time between 1 and 2 seconds. The default is 2
seconds.
p2p [true | false | auto]
–
true
indicates a point-to-point (P2P) link.
P2P ports transition to a forwarding state rapidly thus benefiting from
RSTP. A p2p value of
false
indicates that the port cannot have p2p
status.
auto
allows the port to have p2p status whenever possible
and operate as if the p2p status were true. (A port that operates in
full-duplex is assumed to be point-to-point, while a half-duplex port is
considered as a shared port). If the port cannot maintain this status
(for example if the port is forced to half-duplex operation) the p2p
status changes to operate as if the p2p value were
false
. The default
setting for this parameter is
auto
.
state [enable | disable]
−
Allows STP to be enabled or disabled for
the ports specified in the port list. The default is enabled.
fbpdu [enable | disable | system]
− If enabled
- allows the forwarding
of STP BPDU packets from other network devices Disable –
blocking STP BPDU packets from other network devices. System –
indicates that port will behave as global switch’s fbpdu value
configured. Fbpdu value valid only when STP port state is disabled
or global STP state is disabled. The default is system.
migrate [yes | no]
−
Setting this parameter as “yes” will set the ports
to send out BPDU packets to other bridges, requesting information
on their STP setting if the Switch is configured for RSTP, the port will
be capable to migrate from 802.1D STP to 802.1w RSTP. If the
Switch is configured for MSTP, the port is capable of migrating from
802.1D STP to 802.1s MSTP. RSTP and MSTP can coexist with
standard STP, however the benefits of RSTP and MSTP are not
realized on a port where and 802.1D network connects to and
802.1w or 802.1s enabled network. Migration should be set as yes
on ports connected to network stations or segments that are capable
of being upgraded to 802.1w RSTP or 802.1s MSTP on all or some
portion of the segment.
priority <value 0-240>
−
Specifies the priority. The range is from 0 to
240.
restricted_role [true | false]
−
To decide if this is to be selected as
the Root Port. The default value is false.
restricted_tcn [true | false]
−
To decide if this port is to propagate
