Clearing global IPv6 information

You can clear the following global IPv6 information:

• Entries from the IPv6 cache.

• Entries from the IPv6 neighbor table.

• IPv6 routes from the IPv6 route table.

• IPv6 traffic statistics.

Clearing the IPv6 cache

You can remove all entries from the IPv6 cache or specify an entry based on the following:

• IPv6 prefix.

• IPv6 address.

• Interface type.

For example, to remove entries for IPv6 address 2000:e0ff::1, enter the following command at the

Privileged EXEC level or any of the Config levels of the CLI.

Brocade#clear ipv6 cache 2000:e0ff::1

Syntax: clear ipv6 cache [<ipv6-prefix>/<prefix-length> | <ipv6-address> | ethernet <port> |

tunnel <number> | ve <number>]

You must specify the <ipv6-prefix> parameter in hexadecimal using 16-bit values between colons

as documented in RFC 2373. You must specify the <prefix-length> parameter as a decimal value. A

slash mark (/) must follow the <ipv6-prefix> parameter and precede the <prefix-length>

parameter.

You must specify the <ipv6-address> parameter in hexadecimal using 16-bit values between

colons as documented in RFC 2373.

The ethernet | tunnel | ve parameter specifies the interfaces for which you can remove cache

entries. If you specify an Ethernet interface, also specify the port number associated with the

interface. If you specify a VE or tunnel interface, also specify the VE or tunnel number, respectively.

Clearing IPv6 neighbor information

You can remove all entries from the IPv6 neighbor table or specify an entry based on the following:

• IPv6 prefix

• IPv6 address

• Interface type

For example, to remove entries for Ethernet interface 3/1, enter the following command at the

Privileged EXEC level or any of the CONFIG levels of the CLI.

Brocade#clear ipv6 neighbor ethernet 3/1

Syntax: clear ipv6 neighbor [<ipv6-prefix>/<prefix-length> | <ipv6-address> | ethernet <port> |

ve <number>]
