Chapter 1  GARP and GVRP Configuration Commands

1.1  GARP Configuration Commands

1.1.1  display garp statistics

Syntax

display garp statistics [ interface interface-list ]

View

Any view

Parameters

interface-list: List of Ethernet ports to be displayed, expressed as interface-list = { interface-type interface-number [ to interface-type interface-number] }&<1-10>. interface-type is interface type, and interface-number is interface number. The interface number after the keyword to must be larger than or equal to that before to. &<1-10> represents that the preceding parameter can be repeated up to 10 times.

Description

Use the display garp statistics command to view the GARP statistics information, including the number of packets received/sent and discarded by GVRP/GMRP.

Examples

# Display the GARP statistics information on Ethernet port Ethernet 2/1/1.

<H3C> display garp statistics interface ethernet2/1/1

  GARP statistics on port Ethernet2/1/1

        Number Of GMRP Frames Received          : 0

        Number Of GVRP Frames Received          : 0

        Number Of GMRP Frames Transmitted       : 0

        Number Of GVRP Frames Transmitted       : 0

        Number Of Frames Discarded               : 0

The information above indicates that the number of received/sent packets and the number of packets discarded by GVRP/GMRP on Ethernet 2/1/1 are all 0.

1.1.2  display garp timer

Syntax

display garp timer [ interface interface-list ]

View

Any view

Parameters

interface-list: List of Ethernet ports of which the GARP timer information is to be displayed, expressed as interface-list = { interface-type interface-number [ to interface-type interface-number ] }&<1-10>. interface-type is interface type, and interface-number is interface number. The interface number after the keyword to must be larger than or equal to that before to. &<1-10> means that the preceding parameter can be repeated up to 10 times.

Description

Use the display garp timer command to view the value of GARP timer, including Hold timer, Join timer, Leave timer and LeaveAll timer.

Related commands: garp timer, garp timer leaveall.

Examples

# Display GARP timer on Ethernet 2/1/1.

<H3C> display garp timer interface ethernet2/1/1

      GARP timers on port Ethernet2/1/1

                GARP JoinTime           : 20 centiseconds

                GARP Leave Time         : 60 centiseconds

                GARP LeaveAll Time       : 1000 centiseconds

                GARP Hold Time          : 10 centiseconds

1.1.3  garp timer

Syntax

garp timer { hold | join | leave } timer-value

undo garp timer { hold | join | leave }

View

Ethernet port view

Parameters

hold: GARP Hold timer. After receiving certain registration information, the GARP application entity will not send Join Message at once. Instead, it starts the Hold timer. All the registration information received within duration of the Hold timer will be transmitted in the same frame after the Hold timer times out, thereby saving the bandwidth resource.

join: GARP Join timer. GARP application entity will send out Join message after the Join timer goes timeout to make other GARP application entity register its own information.

leave: GARP Leave timer . When a GARP application entity wants to deregister certain attribute information, it sends Leave message. The GARP application entity receiving the message starts Leave timer. If the entity receives no Join message before the timer goes timeout, it will deregister the attribute information.

timer-value: Value of GARP hold timer, join timer and leave timer in centiseconds. The step is five centiseconds. By default, Hold timer is 10 centiseconds, Join timer is 20 centiseconds, Leave timer is 60 centiseconds.

The range conforms to the following rule:

l           The value of Join timer should be no less than the doubled value of Hold timer.

l           The value of Leave timer should be greater than the doubled value of Join timer and smaller than the Leaveall timer value.

l           The minimal value of Join timer is 10 centiseconds.

Description

Use the garp timer command to set the value of GARP timer (including Hold timer, Join timer and Leave timer) of the port.

Use the undo garp timer command to restore the default value of GARP timer.

The value range of a timer varies with the values of other timers. So if the value of a timer you want to set is not within the available value range, you can change the value range by changing the values of other related timers.

l           The lower limit of Hold timer is 10 centiseconds. You can change its upper limit by changing the value of Join timer.

l           You can change the lower limit and upper limit of Join timer by changing the value of Hold timer and Leave timer respectively.

l           You can change the lower limit and upper limit of Leave timer by changing the value of Join timer and LeaveAll timer respectively.

l           The upper limit of LeaveAll timer is 32765 centiseconds. You can change its lower limit by changing the value of Leave timer.

Related commands: display garp timer.

Examples

# Set Join timer of GARP to 300 ms.

<H3C> system-view

System View: return to User View with Ctrl+Z.

[H3C] interface ethernet 2/1/1

[H3C-Ethernet2/1/1] garp timer join 300

1.1.4  garp timer leaveall

Syntax

garp timer leaveall timer-value

undo garp timer leaveall

View

System view

Parameters

timer-value: Value of GARP LeaveAll timer in centiseconds, ranging from 65 to 32765. The step is five centiseconds. The value of LeaveAll timer should be greater than the value of Leave timer.

Description

Use the garp timer leaveall command to configure GARP LeaveAll timer.

Use the undo garp timer leaveall command to restore the default value.

By default, the value of LeaveAll timer is 1000 centiseconds, that is, 10s.

After every GARP application entity is started, the LeaveAll timer will be started simultaneously. The GARP application entity will send LeaveAll message after the timer times out to make other application entities re-register all attribute information on the entities themselves. Then, the LeaveAll timer is started and the new cycle begins.

Related commands: display garp timer.

Examples

# Set GARP LeaveAll timer to 1s.

<H3C> system-view

System View: return to User View with Ctrl+Z.

[H3C] garp timer leaveall 100

1.1.5  reset garp statistics

Syntax

reset garp statistics [ interface interface-list ]

View

User view

Parameters

interface-list: Specifies a list of Ethernet ports on which the GARP statistics information will be cleared, expressed as interface-list = { interface-type interface-number [ to interface-type interface-num] }&<1-10>. interface-type is interface type, and interface-number is interface number. The interface-number after the keyword to must be larger than or equal to that before to. &<1-10> means that the preceding parameter can be repeated up to 10 times.

Description

Use the reset garp statistics command to reset the GARP statistics information (such as the packets received/sent and discarded by GVRP/GMRP). If the command has no parameter, it will clear the GARP statistics information of all the ports.

Related commands: display garp statistics.

Examples

# Clear GARP statistics information.

<H3C> reset garp statistics

The interface-number after the keyword to must be larger than or equal to that before to. &<1-10> means that the preceding parameter can be repeated up to 10 times.

Description
