Parameters
interface interface-list: Displays the GARP statistics of one or multiple ports. You can specify up to 10 port lists.
You can specify a single port in the form of interface-type interface-number.
You can specify a port range in the form of interface-type interface-number1 to interface-type interface-number2, where the end port number specified by interface-number2 must be greater than the start port number specified by interface-number1.
|: Filters command output by specifying a regular expression. For more information about regular expressions, see Fundamentals Configuration Guide.
begin: Displays the first line that matches the specified regular expression and all lines that follow.
exclude: Displays all lines that do not match the specified regular expression.
include: Displays all lines that match the specified regular expression.
regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.
Description
Use display garp statistics to display the GARP statistics of the specified ports. If no ports are specified, this command displays the GARP statistics for all ports.
This command displays the statistics about GVRP PDUs received, transmitted, and dropped on GVRP-enabled ports. When the system is restarted or after you perform the reset garp statistics command, the existing packet statistics are cleared and the system starts to collect new GARP statistics. With the statistics, you can judge whether a GVRP-enabled port is operating properly.
If the number of received and transmitted GVRP PDUs on the port is the same as the remote port, it indicates that the two ends are transmitting and receiving GVRP PDUs properly and no registration information is lost.
If the port drops GVRP PDUs, you should check its registration mode. GVRP PDUs are likely to be dropped if the registration mode is fixed or forbidden, because dynamic VLANs cannot be registered in these two modes.
Related commands: reset garp statistics.
