sys_attrs_ipv6(5)


NAME

  sys_attrs_ipv6 - ipv6 subsystem attributes


DESCRIPTION

  This reference page lists and describes attributes for the Internet
  Protocol Version 6 (ipv6) kernel subsystem.  Refer to the sys_attrs(5)
  reference page for an introduction to the topic of kernel subsystem
  attributes.

  icmp6_rlimit_enable
      A value that enables (1) or disables (0) rate-limiting of ICMPv6 errors
      (see RFC 2463).

      Default value: 1 (enabled)

  icmp6_rlimit_T
      The maximum time, in milliseconds, to wait before sending ICMPv6 error
      packets to a particular destination IPv6 address.

      Default value: 1000 (milliseconds)

      Minimum value: 1

      Maximum value: LONG_MAX, or 9 quintillion

  icmp6_rlimit_k
      The minimum time, in milliseconds, to wait before sending ICMPv6 error
      packets to a particular destination IPv6 address.

      Default value: 100 (milliseconds)

      Minimum value: 1

      Maximum value: LONG_MAX, or 9 quintillion

  icmp6_rlimit_ntol
      The number of packets to send before starting the ICMPv6 error packet
      rate-limiting timers.

      Default value: 10 (packets)

      Minimum value: 0

      Maximum value: INT_MAX, or 2 billion

  ipv6forwarding
      A value that enables (1) or disables (0) a system's ability to forward
      IPv6 packets that are not addressed to the system.  This functionality
      is usually enabled by using the /usr/sbin/ip6_setup command.

      Default value: 0 (disabled)

      For systems functioning as routers, both ipv6forwarding and ipv6router
      attributes must be 1.  For IPv6 hosts that want to forward source
      routed packets, the ipv6forwarding attribute must be 1.

  ipv6router
      A value that enables (1) or disables (0) a system's ability to forward
      IPV6 packets that are not addressed to the system.  This functionality
      is usually enabled by using the /usr/sbin/ip6_setup command.  When
      enabled, Neighbor Advertisements from the system have the IsRouter flag
      set (see RFC 2461).

      Default value: 0 (disabled)

      For systems functioning as routers, both ipv6forwarding and ipv6router
      attributes must be 1.
