display ipv6 fast-forwarding cache
Use display ipv6 fast-forwarding cache to display IPv6 fast forwarding entries.
Syntax
In standalone mode:
display ipv6 fast-forwarding cache [ ipv6-address ] [ slot slot-number ]
In IRF mode:
display ipv6 fast-forwarding cache [ ipv6-address ] [ chassis chassis-number slot slot-number ]

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 the slot number of the device, which is fixed at 0. Alternatively, you can execute the command without specifying this option. The command execution results are the same. (In standalone mode.)
chassis chassis-number slot slot-number: Specifies 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 device, which is fixed at 0. If you do not specify an IRF member device, this command displays IPv6 fast forwarding entries for all member devices. (In IRF mode.)
Usage guidelines
Each IPv6 fast forwarding entry includes the following fields:
· Source IPv6 address.
· Source port number.
· Destination IPv6 address.
· Destination port number.
· Protocol number.
· VPN instance.
· Input and output interfaces.
Examples
# Display all IPv6 fast forwarding entries.
<Sysname> display ipv6 fast-forwarding cache
Total number of IPv6 fast-forwarding items: 2
Src IP: 2002::1 Src port: 129
Dst IP: 2001::1 Dst port: 65535
Protocol: 58
VPN instance: vpn1
Input interface: GE1/1/2
Output interface: GE1/1/1
Src IP: 2001::1 Src port: 128
Dst IP: 2002::1 Dst port: 0
Protocol: 58
VPN instance: vpn2
Input interface: GE1/1/1
Output interface: GE1/1/2

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
Default
IPv6 fast forwarding load sharing is enabled.

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 five-tuple (source IP, source port, destination IP, destination port, and protocol).
If IPv6 fast forwarding load sharing is disabled, the device identifies a data flow by the five-tuple 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 ]
In IRF mode:
reset ipv6 fast-forwarding cache [ chassis chassis-number slot slot-number ]

Parameters
slot slot-number: Specifies the slot number of the device, which is fixed at 0. Alternatively, you can execute the command without specifying this option. The command execution results are the same. (In standalone mode.)
chassis chassis-number slot slot-number: Specifies 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 device, which is fixed at 0. If you do not specify an IRF member device, this command clears IPv6 fast forwarding entries for all member devices. (In IRF mode.)
Examples
# Clear the IPv6 fast forwarding table.
<Sysname> reset ipv6 fast-forwarding cache
