Clearing Global IPv6 Information

You can clear the following global IPv6 information from a RUCKUS device:

  • 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 parameters:

  • IPv6 prefix
  • IPv6 address
  • Interface type

To remove entries for IPv6 address 2000:e0ff::1, use the clear ipv6 cache command. 

device# clear ipv6 cache 2000:e0ff::1

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.

If you specify an Ethernet interface, also specify the port number associated with the interface. If you specify a VE, VRF, LAG, or tunnel interface, also specify the VE number, VRF name, LAG ID, or tunnel ID, respectively.

Clearing IPv6 Neighbor Information

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

  • IPv6 prefix
  • IPv6 address
  • Interface type
  • Dynamically learned IPv6 neighbors
  • IPv6 neighbors in an incomplete state
  • IPv6 neighbors in a stale state
  • Statically configured IPv6 neighbors
  • Dynamic ND inspection entries
  • ND inspection statistics

To remove entries for Ethernet interface 1/3/1, use the clear ipv6 neighbor command. 

device# clear ipv6 neighbor ethernet 1/3/1

If you specify an Ethernet interface, also specify the port number associated with the interface. If you specify a VRF, LAG or VE interface, also specify the VRF name, LAG ID, or VE number, respectively.

Clearing IPv6 Routes from the IPv6 Route Table

You can clear all IPv6 routes or only those routes associated with a particular IPv6 prefix from the IPv6 route table and reset the routes.

To clear IPv6 routes associated with the prefix 2000:7838::/32, use the clear ipv6 route command. 

device# clear ipv6 route 2000:7838::/32

If you specify a VRF interface, also specify the VRF name.

Clearing IPv6 Traffic Statistics

To clear all IPv6 traffic statistics (reset all fields to zero), use the clear ipv6 traffic command. 

device(config)# clear ipv6 traffic
