3. Show and debug the relating information of ULPP
Command Explanation
Admin Mode
show ulpp group [group-id] Show the configuration information of the
configured ULPP group.
show ulpp flush counter interface { ethernet <IF-
NAME> | <IFNAME> } Show the statistic information of the flush
packets.
show ulpp flush-receive-port Show flush type and control VLAN received
by the port.
clear ulpp flush counter interface <name> Clear the statistic information of the flush
packets.
debug ulpp flush { send | receive } interface
<name>
no debug ulpp flush { send | receive } interface
<name> Show the information of the receiving and
sending flush packets, the no operation dis-
ables the shown information.
debug ulpp flush content interface <name>
no debug ulpp flush content interface <name> Show the contents of the received flush
packets, the no operation disables the
showing.
debug ulpp error
no debug ulpp error Show the error information of ULPP, the no
operation disables the showing.
debug ulpp event
no debug ulpp event Show the event information of ULPP, the no
operation disables the showing.
59.3 ULPP Typical Examples
59.3.1 ULPP Typical Example 1
The above topology is the typical application environment of ULPP protocol.
SwitchA has two uplinks, they are SwitchB and SwitchC. When any protocols are not enabled,
this topology forms a ring. For avoiding the loopback, SwitchA can configure ULPP protocol, the
master port and the slave port of ULPP group. When both master port and slave port are up, the
slave port will be set as standby state and will not forward the data packets. When the master
port is down, the slave port will be set as forwarding state and switch to the uplink. SwitchB and
SwitchC can enable the command that receives the flush packets, it is used to associate with
ULPP protocol running of SwitchA to switch the uplink immediately and reduce the switch delay.
When configuring ULPP protocol of SwitchA, first, create a ULPP group and configure the
protection VLAN of this group as vlan10, then configure interface Ethernet 1/0/1 as the master
port, interface Ethernet 1/0/2 as the slave port, the control VLAN as 10. SwitchB and SwitchC
configure the flush packets that receive ULPP.
