Setting The Link Type Of A Port To P2P - 3Com 5500-EI PWR Install Manual

To do...
Enter Ethernet port view
Configure the port as an edge
port
On a switch with BPDU guard disabled, an edge port becomes a non-edge port again once it receives a
BPDU from another port.
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...
Enter system view
Specify whether the link
connected to a port is
point-to-point link
Use the command...
interface interface-type
interface-number
stp edged-port enable
Use the command...
system-view
stp interface interface-list
point-to-point { force-true |
force-false | auto }
1-27
Remarks
—
Required
By default, all the Ethernet
ports of a switch are non-edge
ports.
Remarks
—
Required
The auto keyword is adopted
by default.
