Clearing Ipv6 Tunnel Statistics; Displaying Ipv6 Tunnel Information - Brocade Communications Systems FastIron Administration Manual

The ipv6 enable command enables the tunnel. Alternatively, you could specify an IPv6 address, which
would also enable the tunnel.
Syntax: ipv6 address ipv6-prefix / prefix-length [ eui-64 ]
The ipv6 address command enables the tunnel. Alternatively, you could enter ipv6 enable , which
would also enable the tunnel.
Specify the ipv6-prefix parameter in hexadecimal format using 16-bit values between colons as
documented in RFC 2373.
Specify the prefix-length parameter as a decimal value. A slash mark (/) must follow the ipv6-prefix
parameter and precede the prefix-length parameter. The eui-64 keyword configures the global address
with an EUI-64 interface ID in the low-order 64 bits. The interface ID is automatically constructed in
IEEE EUI-64 format using the interface's MAC address.

Clearing IPv6 tunnel statistics

You can clear statistics (reset all fields to zero) for all IPv6 tunnels or for a specific tunnel interface.
For example, to clear statistics for tunnel 1, enter the following command at the Privileged EXEC level
or any of the Config levels of the CLI.
device#clear ipv6 tunnel 1
To clear statistics for all IPv6 tunnels, enter the following command.
device#clear ipv6 tunnel
Syntax: clear ipv6 tunnel [number]
The number parameter specifies the tunnel number.
