Restore the default setting, non-edge
port, of the port.
II. Configure in Ethernet port view
Perform the following configuration in Ethernet port view.
Table 1-13 Configure a port as an edge port or a non-edge port
Configure a port as an edge port.
Configure a port as a non-edge port.
Restore the default setting, non-edge port, of the port.
You can configure a port as an edge port or a non-edge port with either of the
above-mentioned measures. For more about the commands, refer to the Command
Manual.
After configured as an edge port, the port can fast transit from blocking state to
forwarding state without any delay. In the case that BPDU protection has not been
enabled on the switch, the configured edge port will turn into non-edge port again when
it receives BPDU from other port. In the case that BPDU protection is enabled, the port
will be disabled. The configuration of this parameter takes effect on all the STIs. In other
words, if a port is configured as an EdgedPort or Non- EdgedPort, it is configured the
same on all the STIs.
It is better to configure the BPDU protection on the edged port, so as to prevent the
switch from being attacked.
Before BPDU protection is enabled on the switch, the port runs as a non-edge port
when it receives BPDU, even if the user has set it as an edge port.
By default, all the Ethernet ports of the switch have been configured as non-edge ports.
Note:
It is better to configure the port directly connected with terminal as the edged port, and
enable the BPDU function on the port. That is to realize fast state-transition and prevent
the switch from being attacked.
