3Com 4500 Switch User Manual

You are recommended to configure the Ethernet ports connected directly to terminals as edge ports
and enable the BPDU guard function at the same time. This not only enables these ports to turn to the
forwarding state rapidly but also secures your network.
Configuration example
# Configure Ethernet 1/0/1 as an edge port.
1) Configure Ethernet 1/0/1 as an edge port in system view
<Sysname> system-view
[Sysname] stp interface Ethernet 1/0/1 edged-port enable
2) Configure Ethernet 1/0/1 as an edge port in Ethernet port view
<Sysname> system-view
[Sysname] interface Ethernet 1/0/1
[Sysname-Ethernet1/0/1] stp edged-port enable
Setting the Link Type of a Port to P2P
A point-to-point link directly connects two switches. If the roles of the two ports at the two ends of a
point-to-point link meet certain criteria, the two ports can turn to the forwarding state rapidly by
exchanging synchronization packets, thus reducing the forward delay.
You can determine whether or not the link connected to a port is a point-to-point link in one of the
following two ways.
Setting the Link Type of a Port to P2P in system view
Follow these steps to specify whether the link connected to a port is point-to-point link in system view:
To do... Use the command... Remarks
Enter system view
system-view
Specify whether the link
connected to a port is
point-to-point link
stp interface interface-list
point-to-point { force-true |
force-false | auto }
Required
The auto keyword is adopted
by default.
Setting the Link Type of a Port to P2P in Ethernet port view
