Edge Port BPDU Filtering :
Control whether a port explicitly configured as Edge will transmit and receive
BPDUs.
Edge Port BPDU Guard :
Control whether a port explicitly configured as Edge will disable itself upon
reception of a BPDU. The port will enter the error-disabled state, and will be
removed from the active topology.
Port Error Recovery :
Control whether a port in the error-disabled state automatically will be enabled
after a certain time. If recovery is not enabled, ports have to be disabled and
re-enabled for normal STP operation. The condition is also cleared by a system
reboot.
Port Error Recovery Timeout :
The time to pass before a port in the error-disabled state can be enabled. Valid
values are between 30 and 86400 seconds (24 hours).

2-4.2 MSTI Mapping
Implement a Spanning Tree protocol on the switch. The CIST is not available for explicit
mapping, because it will receive the VLANs not explicitly mapped. You need to set the list of
VLANs mapped to the MSTI. The VLANs must be separated with comma and/or space. A
VLAN can only be mapped to one MSTI. An unused MSTI should just be left empty. (I.e. not
having any VLANs mapped to it.)
This section describes how the user can inspect the current STP MSTI bridge instance priority
configurations, and possibly change them as well.
Web Interface
To configure the Spanning Tree MSTI Mapping parameters in the Web interface:
1. Click Configuration, Spanning Tree, MSTI Mapping.
2. Specify the configuration identification parameters in the field. Specify the VLANs Mapped
blank field.
3. Click the save button to save the setting
4. If you want to cancel the setting, then you need to click the Reset button. It will revert to
previously saved values
