sys_attrs_ipv6 - ipv6 subsystem attributes
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.
A value that enables (1) or disables (0) rate-limiting
of ICMPv6 errors (see RFC 2463).
Default value: 1 (enabled)
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
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
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
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.
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.
The level of debugging for Mobile IPv6 functionality.
Do not enable this attribute during normal
system use.
Default value: 0 (disabled)
Minimum value: 0
Maximum value: 4
The supported debug values are as follows: None
Basic binding added, changed, and deleted messages.
The same information as the previous level and IPv6
input (Home Address), binding lookups, binding
update processing, and simple routing header messages.
The same information as the previous level
and more detailed routing header, mbuf, and upperlayer
caching messages. The same information as
the previous level and timer debugging.
All debugging levels greater than 0 (zero) include
Mobile IPv6 error messages.
A value that enables (1) or disables (0) Mobile
IPv6 functionality.
Default value: 0 (disabled)
The maximum binding cache lifetime, in seconds,
allowed for Mobile IPv6 bindings.
Default value: UINT_MAX, or 4 billion (seconds), or
infinite lifetime
Minimum value: 0
Maximum value: UINT_MAX, or 4 billion
