Parameters <portlist> - Specifies a range of ports to be configured.
externalCost - This defines a metric that indicates the relative cost of
forwarding packets to the specified port list. Port cost can be set automatically
or as a metric value. The default value is auto.
auto – Setting this parameter for the external cost will automatically set the
speed for forwarding packets to the specified port(s) in the list for optimal
efficiency. Default port cost: 100Mbps port = 200000. Gigabit port = 20000.
<value 1-200000000> - Define 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.
hellotime <value 1-2> - The time interval between transmission of
configuration messages by the designated 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.
migrate [yes | no] – Setting this parameter as “yes” will set the ports to send
out BDPU 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 an 802.1D network connects to an
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.
edge [true | false | auto] – true designates 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. Setting the value to true under STP mode has no effect.
false indicates that the port does not have edge port status.
p2p [true | false | auto] – true indicates a point-to-point (P2P) shared link. P2P
ports are similar to edge ports however they are restricted in that a P2P port
must operate in full-duplex. Like edge ports, 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. 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 enable.
restricted_role - To decide if this is to be selected as the Root Port. The
default value is false.
restricted_tcn
- To decide if this port is to propagate topology change. The
default value is false.
fbpdu [enable | disable] - When enabled, this allows the forwarding of STP
BPDU packets from other network devices when STP is disabled in the
specified ports. If users want to enable Forwarding BPDU on a per port basis,
the following settings must first be in effect: 1. STP must be globally disabled
and 2. Forwarding BPDU must be globally enabled. To globally disable STP,
use the disable stp command, to globally enable fbpdu, use the config stp
command. The default is enable.
Restrictions Only Administrator-level users can issue this command.
