display garp
statistics [ interface interface-list ]

Parameters
interface-list: Specifies a list of Ethernet ports for which the statistics about
GARP are to be displayed. In this list, you can specify individual ports
and port ranges. An individual port takes the form of interface-type
interface-number and a port range takes the form of interface-type
interface-number1 to interface-type interface-number2, with interface-number2
taking a value greater than interface-number1. The total number of
individual ports and port ranges defined in the list must not exceed 10.
Description
Use the display garp statistics
command to display the GARP statistics of the specified or all ports. If the interface
interface-list keyword-argument combination is not specified, this command
displays the GARP statistics on all the ports.
The switch automatically collects
statistics about GVRP packets sent, received and dropped on GVRP-enabled ports.
You can check whether GVRP is running normally on a port by checking the GVRP
statistics on it:
l
If the number of received GVRP packets and the
number of sent GVRP packets are the same as those on the remote port, it
indicates that the ports are transmitting and receiving GVRP packets normally
and no registration information is lost.
l
If the number of dropped GVRP packets is not 0,
it indicates that the registration mode on the port may be fixed or forbidden.
As in either mode dynamic VLANs cannot be registered, GVRP packet drop may
occur on the port.

Parameters
interface-list: Specifies a list of Ethernet ports of which the GARP timer
settings are to be displayed. In this list, you can specify individual
ports and port ranges. An individual port takes the form of interface-type
interface-number and a port range takes the form of interface-type
interface-number1 to interface-type interface-number2, with interface-number2
taking a value greater than interface-number1. The total number of
individual ports and port ranges defined in the list must not exceed 10.
Description
Use the display garp timer
command to display the settings of the GARP timers on specified ports or all
ports.
If the interface interface-list
keyword-argument combination is not specified, this command displays the GARP
timer settings of all ports.
This command displays the settings of the
following timers:
l
Join timer
l
Leave timer
l
LeaveAll timer
l
Hold timer
Related commands: garp timer, garp
timer leaveall.

Parameters
hold: Sets
the GARP Hold timer.
join: Sets
the GARP Join timer.
leave: Sets
the GARP Leave timer.
timer-value:
Timeout time (in centiseconds) of the GARP timer (Hold, Join or Leave) to be
set.
Description
Use the garp timer command to set a GARP
timer (that is, the Hold timer, the Join timer, or the Leaver timer) for an
Ethernet port.
Use the undo garp timer command to
restore the default setting of a GARP timer.
By default, the Hold, Join, and Leave
timers are set to 10, 20, and 60 centiseconds.
Note that:
l
The setting of each timer must be a multiple of
5 (in centiseconds).
l
The timeout ranges of the timers vary depending on
the timeout values you set for other timers. If you want to set the timeout
time of a timer to a value out of the current range, you can set the timeout
time of the associated timer to another value to change the timeout range of
this timer.
The following table describes the relations
between the timers:

This lower threshold is greater than or
equal to twice the timeout time of the Hold timer. You can change the
threshold by changing the timeout time of the Hold timer.

This upper threshold is less than
one-half of the timeout time of the Leave timer. You can change the threshold
by changing the timeout time of the Leave timer.

|
Leave
|
This lower threshold is greater than
twice the timeout time of the Join timer. You can change the threshold by changing
the timeout time of the Join timer.

This upper threshold is less than the timeout
time of the LeaveAll timer. You can change the threshold by changing the timeout
time of the LeaveAll timer.

In networking, the following GARP timer settings are recommended:
l
GARP hold timer: 100 centiseconds (1 second)
l
GARP Join timer: 600 centiseconds (6 seconds)
l
GARP Leave timer: 3000 centiseconds (30 seconds)

Parameters
timer-value:
Setting (in centiseconds) of the GARP LeaveAll timer. You need to set this
argument with the Leave timer settings of other Ethernet ports as references.
That is, this argument needs to be larger than the Leave timer settings of any
Ethernet ports. Also note that this argument needs to be a multiple of 5 and
cannot be larger than 32,765.
Description
Use the garp timer leaveall command
to set the GARP LeaveAll timer.
Use the undo garp timer leaveall
command to restore the default setting of the GARP LeaveAll timer.
By default, the LeaveAll timer is set to
1,000 centiseconds, that is, 10 seconds.
In networking, you
are recommended to set the GARP LeaveAll timer to 12000 centiseconds (2
minutes).

Parameters
interface-list: Specifies a list of Ethernet ports. In this list, you can
specify individual ports and port ranges. An individual port takes the form of interface-type
interface-number and a port range takes the form of interface-type
interface-number1 to interface-type interface-number2, with interface-number2
taking a value greater than interface-number1. The total number of
individual ports and port ranges defined in the list must not exceed 10.
Description
Use the reset garp statistics
command to clear the GARP statistics (including statistics about packets
received/sent/discarded by GVRP) on the specified or all ports.
Executing the reset garp statistics
command without any parameter clears the GARP statistics of all ports.
Related commands: display garp

Syntax
display gvrp statistics [ interface interface-list ]
View
Any view
Parameters
interface interface-list:
Specifies an Ethernet port list. By providing a value for this argument, you
can display the GVRP statistics on the specified ports. You need to provide the
interface-list argument in the format of { interface-type
interface-number [ to interface-type interface-number ] }
&<1-10>, where the interface-type argument represents the port
type, the interface-number argument represents the port number, and
& <1-10> means that you can provide up to 10 port indexes/port index
ranges for this argument.
Note that, this command displays GVRP
statistics only on the trunk ports included in the list. Statistics on
non-trunk ports will not be displayed.
Description

command to display the GVRP statistics of trunk ports.
This command displays the following information:
l
GVRP status
l
Number of the GVRP entries that fail to be
registered

Parameters
None
Description
Use the gvrp command to enable GVRP
globally (in system view) or for a port (in Ethernet port view).
Use the undo gvrp command to disable
GVRP globally (in system view) or on a port (in Ethernet port view).

and on ports.
Note that:
l
To enable GVRP for a port, you need to enable
GVRP globally first.
l
You can enable/disable GVRP only on trunk ports.

Parameters
fixed:
Specifies the fixed GVRP registration mode. A port operating in this mode cannot
register or deregister VLAN information dynamically. It only propagates static
VLAN information. Besides, the port permits only static VLANs, that is, it
propagates only static VLAN information to the other GARP members.
forbidden:
Specifies the forbidden GVRP registration mode. A port operating in this mode
cannot register or deregister VLAN information dynamically. It permits only
VLAN 1, that is, it propagates only the information about VLAN 1 to the other
GARP members.
normal:
Specifies the normal mode. A port operating in this mode can dynamically register
or deregister VLAN information and can propagate both dynamic and static VLAN
information.
Description
Use the gvrp registration
command to configure the GVRP registration mode on a port.
Use the undo gvrp registration
command to restore the default GVRP registration mode on a port.
By default, the GVRP registration mode is normal.
Note that these commands only apply to trunk
ports.
