The edge interface can change the interface status to forward quickly without any waiting
time. You had better configure the Ethernet interface connected to user client as edge interface
to make it quick to change to forward status.
The edge interface attribute depends on actual condition when it is in auto-detection mode;
the real port will change to false edge interface after receiving BPDU when it is in force-true
mode; when the interface is in force-false mode, whether it is true or false edge interface in
real operation, it will maintain the force-false mode until the configuration is changed.
By default, all interfaces on the ISCOM2600G-HI series switch are configured in auto-
detection attribute.
Configure the edge interface for the ISCOM2600G-HI series switch as below.
Step
Command

force-false }
Configure attributes of the RSTP
edge interface.
2.7.14 Configuring BPDU filtering
After being enabled with BPDU filtering, the edge interface does not send BPDU packets nor
process received BPDU packets.
Configure BPDU filtering for the ISCOM2600G-HI series switch as below.
Step
Command
Description
1
Raisecom#config
Enter global configuration mode.
2
Raisecom(config)#interface
interface-type interface-number
Enter physical layer interface
configuration mode.
3
Raisecom(config-
gigaethernet1/1/port)#spanning-tree
edged-port bpdu-filter enable
interface-type interface-number
Enable BPDU filtering on the
edge interface.
2.7.15 Configuring BPDU Guard
On a switch, interfaces directly connected with non-switch devices, such as terminals (such as
a PC) or file servers, are configured as edge interfaces to implement fast transition of these
interfaces.
In normal status, these edge interfaces do not receive BPDUs. If forged BPDU attacks the
switch, the switch will configure these edge interfaces to non-edge interfaces when these edge
interfaces receive forged BPDUs and re-perform spanning tree calculation. This may cause
network vibration.
