config stp ports
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.
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.
lbd [enable | disable]
Used to enable or disable the loop-back detection function
on the switch for the ports configured above in the
config stp
command.
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.
