config stp ports
Purpose Used to setup STP on the port level.
Syntax
config stp ports <portlist> {cost <value>|priority <value>| migrate
[yes|no]| edge [true|false]| p2p [true|false]| state [enable|disable]
Description This command is used to create and configure STP for a group of ports.
cost <value> − This defines a metric that indicates the relative cost of
Parameters
forwarding packets to the specified port list. Port cost can be set from 1 to
200000000. The lower the number, the greater the probability the port will be
chosen to forward packets.
Default port cost: 100Mbps port = 200000
priority <value> − Port Priority can be from 0 to 240. The lower the number, the
greater the probability the port will be chosen as the Root Port. Default = 128.
<portlist> − Specifies a range of ports to be configured. The port list is
specified by listing the lowest Switch number and the beginning port number
on that Switch, separated by a colon. Then the highest Switch number, and
the highest port number of the range (also separated by a colon) are specified.
The beginning and end of the port list range are separated by a dash. For
example, 1:3 specifies Switch number 1, port 3. 2:4 specifies Switch number
2, port 4. 1:3-2:4 specifies all of the ports between Switch 1, port 3 and Switch
2, port 4 − in numerical order.
migrate [yes|no] – yes will enable the port to migrate from 802.1d STP status
to 802.1w RSTP status. RSTP can coexist with standard STP, however the
benefits of RSTP are not realized on a port where an 802.1d network connects
to an 802.1w enabled network. Migration should be enabled (yes) on ports
connected to network stations or segments that will be upgraded to 802.1w
RSTP onall or some portion of the segment.
edge [true|false] – 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. 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.
state [enable|disable] − Allows STP to be enabled or disabled for the ports
specified in the port list. The default is disabled.
Only administrator-level users can issue this command.
