Syntax

display ipv6 statistics [ slot slot-number ] [ | { begin | exclude | include } regular-expression ]

Default level

1: Monitor level

Parameters

slot slot-number: Displays the IPv6 and ICMPv6 packets statistics on a specific IRF member switch. The slot-number argument specifies the ID of an IRF member switch. The value range for the argument depends on the number of member switches and their member IDs in the IRF fabric, which you can display with the display irf command. On a standalone device, the slot-number argument specifies the ID of the device.

|: 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 ipv6 statistics to display statistics of IPv6 packets and ICMPv6 packets.

You can use the reset ipv6 statistics command to clear all IPv6 and ICMPv6 packet statistics.
