Parameters
ipv6-address: Specifies an IPv6 address. If you do not specify an IPv6 address, this command displays all IPv6 fast forwarding entries.
slot slot-number: Specifies a card by the slot number. If you do not specify a card, this command displays IPv6 fast forwarding entries for all cards. (In standalone mode.)
chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. If you do not specify a card, this command displays IPv6 fast forwarding entries for all cards. (In IRF mode.)
cpu cpu-number: Specifies a CPU by its number. This option is available only if multiple CPUs are available on the specified slot.
Examples
# Display all IPv6 fast forwarding entries.
<Sysname> display ipv6 fast-forwarding cache

ipv6 fast-forwarding load-sharing
Use ipv6 fast-forwarding load-sharing to enable IPv6 fast forwarding load sharing.
Use undo ipv6 fast-forwarding load-sharing to disable IPv6 fast forwarding load sharing.
Syntax
ipv6 fast-forwarding load-sharing
undo ipv6 fast-forwarding load-sharing

Usage guidelines
IPv6 fast forwarding load sharing enables the device to load share packets of the same flow. This feature identifies a data flow by using the packet information.
If IPv6 fast forwarding load sharing is disabled, the device identifies a data flow by the packet information and the input interface. No load sharing is implemented.
Examples
# Enable IPv6 fast forwarding load sharing.
<Sysname> system-Views
[Sysname] ipv6 fast-forwarding load-sharing
reset ipv6 fast-forwarding cache
Use reset ipv6 fast-forwarding cache to clear the IPv6 fast forwarding table.
Syntax
In standalone mode:
reset ipv6 fast-forwarding cache [ slot slot-number [ cpu cpu-number ] ]
In IRF mode:
reset ipv6 fast-forwarding cache [ chassis chassis-number slot slot-number [ cpu cpu-number ] ]

Parameters
slot slot-number: Specifies a card by its slot number. If you do not specify a card, this command clears the IPv6 fast forwarding table for all cards. (In standalone mode.)
chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. If you do not specify a card, this command clears the IPv6 fast forwarding table for all cards. (In IRF mode.)
cpu cpu-number: Specifies a CPU by its number. This option is available only if multiple CPUs are available on the specified slot.
