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 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. (In IRF mode.)

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.

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 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 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. (In IRF mode.)

Examples

# Clear the IPv6 fast forwarding table.

<Sysname> reset ipv6 fast-forwarding cache
