interface
description text
Optional
By default, the description of a
tunnel interface is Tunnelnumber
Interface.
Set the MTU for IPv4
packets sent over the

mtu size
Set the MTU
of the tunnel
interface
Set the MTU for IPv6
packets sent over the

Shut down the tunnel interface shutdown
Optional
By default, the interface is up.
NOTE:
•
For more information about the ipv6 mtu command, see IPv6 Basics Commands in the IP Services

• Whether a packet can be sent successfully depends on the bandwidth of the tunnel interface and
especially that of the output interface of the packet. You must refer to the bandwidth of the output
interface when setting the bandwidth of the tunnel interface with the tunnel bandwidth command.

Configuration Prerequisites
Configure IP addresses for interfaces (such as the VLAN interface, GigabitEthernet interface, and
loopback interface) on the device to ensure normal communication. One of the interfaces will be used as
the source interface of the tunnel.
