Description
Use the ipv6 nd nud reachable-time command to configure the neighbor reachable time on an
interface.
Use the undo ipv6 nd nud reachable-time command to restore the default.
By default, the neighbor reachable time on the local interface is 30,000 milliseconds.
Related commands: display ipv6 interface.
Examples
# Set the neighbor reachable time on the VLAN-interface 1 to 10,000 milliseconds.

Parameters
ipv6-address: IPv6 address in a static neighbor entry.
mac-address: Link layer address in a static neighbor entry (48 bits long, in the format of H-H-H).
vlan-id: VLAN ID corresponding to a static neighbor entry, in the range of 1 to 4094.
port-type port-number: Ethernet port type and port number corresponding to a static neighbor entry.
interface-type interface-number: VLAN interface type and interface number corresponding to a static
neighbor entry.
Description
Use the ipv6 neighbor command to configure a static neighbor entry.
Use the undo ipv6 neighbor command to remove a static neighbor entry.
Note that:
You can configure a static neighbor entry in two ways:
z Mapping a VLAN interface to an IPv6 address and a link-layer address. The entry state is INCMP.
After the switch get the layer 2 port information of the VLAN, the neighbor entry enters the REACH
state.
z Mapping a Layer 2 port in a VLAN to an IPv6 address and a link-layer address. The Layer 2 port
specified by the port-type port-number argument must belong to the VLAN specified by the vlan-id
argument, and the corresponding VLAN interface must exist. After you carry out the command, the
