Maintaining IPv6

Maintaining IPv6

This section describes how to clear IPv6 statistics and monitor the IPv6 operating status.

Clearing IPv6 Statistics

This section describes how to clear IPv6 statistics.

Context

IPv6 statistics cannot be restored after they are cleared. Exercise caution when running reset commands.

Procedure

  • Run the reset ipv6 statistics command in the user view to clear IPv6 statistics.
  • Run the reset tcp ipv6 statistics command in the user view to clear TCP6 statistics.
  • Run the reset udp ipv6 statistics command in the user view to clear UDP6 statistics.
  • Run the reset ipv6 pathmtu [ vpn-instance vpn-instance-name ] dynamic command in the user view to clear the PMTU entries in the buffer.
  • Run the reset ipv6 neighbors { dynamic | interface-type interface-number } command in the user view to clear IPv6 neighbor configurations.
  • Run the reset ipv6 nd security statistics interface-type interface-numbercommand in the user view to clear statistics on IPv6 SEND messages on a specified interface.
  • Run the reset ipv6 nd security timestamp interface-type interface-numbercommand in the user view to clear the timestamp of an IPv6 SEND message on a specified interface.
  • Run the reset ipv6 nd security nonce interface-type interface-numbercommand in the user view to clear the Nonce value of an IPv6 SEND message on a specified interface.
  • To clear statistics about packets that have been discarded because the packets' destination MAC addresses are different from an interface's MAC address or the packets' sizes exceed the interface's MTU, run the reset forward-statistics packet discard [ mac | mtu ] ipv6 { interface [ interface-type interface-number ] | slot slot-id } command.

Monitoring the IPv6 Operating Status

This section describes how to monitor the IPv6 operating status.

Context

You can run the following command in any view to check the IPv6 operating status in routine maintenance.

Procedure

  • Run the display ipv6 interface [ interface interface-type interface-number | brief ] command to check IPv6 configurations on an interface.
  • Run the display ipv6 statistics [ interface interface-type interface-number ] command to check IPv6 statistics.
  • Run the display icmpv6 statistics [ interface interface-type interface-number ] command to check ICMPv6 statistics.
  • Run the display tcp ipv6 statistics command to check TCP6 statistics.
  • Run the display ipv6 neighbors [ interface-type interface-number | ipv6-address | vpn-instance vpn-instance-name ] command to check IPv6 neighbor configurations.
  • Run the display ipv6 address-policy [ vpn-instance vpn-instance-name ] { all | ipv6-address prefix-length } command to check address selection policy entries.
  • Run the display ipv6 pathmtu [ vpn-instance vpn-instance-name ] { ipv6-address | all | dynamic | static } command to check all PMTU entries.
  • Run the display ipv6 nd security timestamp interface-type interface-number command in any view to check the timestamp of an IPv6 SEND message.
  • Run the display ipv6 nd security nonce interface-type interface-number command in any view to check the Nonce value of an IPv6 SEND message.
  • Run the display ipv6 nd security statistics interface-type interface-number command in any view to check the statistics on IPv6 SEND messages.
  • Run the display forward-statistics packet discard [ mac | mtu ] [ ipv6 | ipv6 ] { interface interface-type interface-number | slot slot-id } command to view statistics about packets that have been discarded because the packets' destination MAC addresses are different from an interface's MAC address or the packets' sizes exceed the interface's MTU.
