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. (Distributed devices in standalone mode.)

slot slot-number: Specifies an IRF member device by its member ID. If you do not specify a member device, this command displays IPv6 fast forwarding entries for all member devices. (Centralized IRF devices.) (IRF 3 incapable.)

slot slot-number: Specifies an IRF member device by its member ID or specifies a PEX by its virtual slot number. On an IRF fabric, this command displays IPv6 fast forwarding entries for all member devices if you do not specify a member device. On an IRF 3 system, this command displays IPv6 fast forwarding entries for all IRF member devices and PEXs if you do not specify an IRF member device or PEX. (Centralized IRF devices.) (IRF 3 capable.)

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. (Distributed devices in IRF mode.) (IRF 3 incapable.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device or specifies a PEX. The chassis-number argument represents the member ID of the IRF member device or the virtual chassis number of the PEX. The slot-number argument represents the slot number of the card or PEX. On an IRF fabric, this command displays IPv6 fast forwarding entries for all cards if you do not specify a card. On an IRF 3 system, this command displays IPv6 fast forwarding entries for all cards and PEXs if you do not specify a card or PEX. (Distributed devices in IRF mode.) (IRF 3 capable.)

cpu cpu-number: Specifies a CPU by its number. This option is available only if multiple CPUs are available on the specified slot.

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

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. (Distributed devices in standalone mode.)

slot slot-number: Specifies an IRF member device by its member ID. If you do not specify a member device, this command clears the IPv6 fast forwarding table for all member devices. (Centralized IRF devices.) (IRF 3 incapable.)

slot slot-number: Specifies an IRF member device by its member ID or specifies a PEX by its virtual slot number. On an IRF fabric, this command clears the IPv6 fast forwarding table for all member devices if you do not specify a member device. On an IRF 3 system, this command clears the IPv6 fast forwarding table for all IRF member devices and PEXs if you do not specify an IRF member device or PEX. (Centralized IRF devices.) (IRF 3 capable.)

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. (Distributed devices in IRF mode.) (IRF 3 incapable.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device or specifies a PEX. The chassis-number argument represents the member ID of the IRF member device or the virtual chassis number of the PEX. The slot-number argument represents the slot number of the card or PEX. On an IRF fabric, this command clears the IPv6 fast forwarding table for all cards if you do not specify a card. On an IRF 3 system, this command clears the IPv6 fast forwarding table for all cards and PEXs if you do not specify a card or PEX. (Distributed devices in IRF mode.) (IRF 3 capable.)

cpu cpu-number: Specifies a CPU by its number. This option is available only if multiple CPUs are available on the specified slot.
