Brocade Communications Systems 6650 manual Clearing IPv6 tunnel statistics

5 IPv6 over IPv4 tunnels

Brocade(config)#interface tunnel 1

Brocade(config-tnif-1)#tunnel source ethernet 1/1/1

Brocade(config-tnif-1)#tunnel destination 192.162.100.1

Brocade(config-tnif-1)#tunnel mode ipv6ip

Brocade(config-tnif-1)#ipv6 enable

This example creates tunnel interface 1 and assigns a link local IPv6 address with an automatically computed EUI-64 interface ID to it. The IPv4 address assigned to Ethernet interface 1/1/1 is used as the tunnel source, while the IPv4 address 192.168.100.1 is configured as the tunnel destination. The tunnel mode is specified as a manual IPv6 tunnel. Finally, the tunnel is enabled. Note that instead of entering ipv6 enable, you could specify an IPv6 address, for example, ipv6 address 2001:DB8:384d:34::/64 eui-64, which would also enable the tunnel.

Syntax: [no] interface tunnel <number>

For the <number> parameter, specify a value between 1 – 8.

Syntax: [no] tunnel source <ipv4-address> ethernet <stack-unit>/<slot>/<port> loopback <number> ve <number>

The tunnel source can be an IP address or an interface.

For <ipv4-address>, use 8-bit values in dotted decimal notation.

The ethernet loopback ve parameter specifies an interface as the tunnel source.Specify the ethernet port in the <stack-unit>/<slot>/<port>format. Stack-unit is 1.

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

Syntax: [no] tunnel destination <ipv4-address>

Specify the <ipv4-address>parameter using 8-bit values in dotted decimal notation.

Syntax: [no] tunnel mode ipv6ip

ipv6ip indicates that this is an IPv6 manual tunnel.

Syntax: ipv6 enable

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-64keyword 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.
