DES-3500 Layer 2 Fast Ethernet Switch CLI Reference Manual
(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.
fbpdu [enable | disable | hw_filtering] − 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 disable.
When the state is set to hw_filtering, if STP BPDU is received by this port, the port
will be changed to BPDU hardware filtering mode such that all layer 2 control
packets will be dropped by hardware. The default is disable.
recover_hw_filtering − When a port is in BPDU hardware filtering mode, it can be
recovered by this option.
The following MAC addresses are layer 2 control packets:
NOTE:
01:80:C2:00:00:00 to 01:80:C2:00:00:10 and 01:80:C2:00:00:20 to
01:80:C2:00:00:2F.
Only Administrator and Operator-level users can issue this command.
Used to create a STP instance ID for MSTP.
create stp instance_id <value 1-4>
This command allows the user to create a STP instance ID for the
Multiple Spanning Tree Protocol. There are 5 STP instances on
the Switch (one internal CIST, unchangeable) and the user may
create up to 4 instance IDs for the Switch.
<value 1-4> - Enter a value between 1 and 4 to identify the
Spanning Tree instance on the Switch.
Only Administrator and Operator-level users can issue this
command.
