ndp enable
Syntax
ndp enable [ interface interface-list ]
undo ndp enable [ interface interface-list ]
View
System view, Ethernet port view
Parameters
interface-list: Ethernet port list, in the format of { interface-type interface-number [ to interface-type
interface-number ] } &<1-10>, where to is used to specify a port range, and &<1-10> means that you
can provide up to ten port indexes/port index ranges for this argument. The interface-number argument
is in the format of unit ID/slot number/port number.
Description
Use the ndp enable command to enable NDP globally or on a port.
Use the undo ndp enable command to disable NDP globally or on a port.
If you execute the ndp enable command in system view without the interface keyword specified, NDP
will be enabled globally; if you specify the interface keyword in the command, NDP will be enabled on
the specified ports. In Ethernet port view, the interface keyword is unavailable, and execution of the
command will enable NDP on the current port only.
By default, NDP is enabled both globally and on ports.
Note that NDP can take effect on a port only when NDP is enabled both globally and on the port.
Examples
# Enable NDP globally, and then enable NDP on port Ethernet 1/0/1.
