Usage
Information
You cannot delete a physical interface.
By default, physical interfaces are disabled (shutdown) and are not assigned to an IP
address or switchport. To place an interface in Layer 2 mode, ensure that the interface’s
configuration does not contain an IP address and enter the
switchport command.
You can create up to 64 tunnel interfaces. The tunnel is added as a logical interface with no
default configuration. To delete a tunnel interface, use the no interface tunnel
tunnel-id command.
