Defaults
Enabled
Command Modes
INTERFACE
ipv6 neighbor
e
Configure a static entry in the IPv6 neighbor discovery.
Syntax
ipv6 neighbor {ipv6-address} {interface interface} {hardware_address}
To remove a static IPv6 entry from the IPv6 neighbor discovery, use the no ipv6 neighbor
{ipv6-address} {interface interface} command.
Parameters
Defaults
No default behavior or values
Command Modes
CONFIGURATION
show ipv6 neighbors
e
Display IPv6 discovery information. Entering the command without options shows all IPv6 neighbor
addresses stored on the CP (control processor).
Syntax
show ipv6 neighbors [ipv6-address] [cpu {rp1 [ipv6-address] | rp2 [ipv6-address]}]
[interface interface]
Parameters
ipv6-address Enter the IPv6 address of the neighbor in the x:x:x:x::x format.
The
:: notation specifies successive hexadecimal fields of zero
interface interface Enter the keyword interface followed by the interface type and slot/port or
number information:
• For a Fast Ethernet interface, enter the keyword
fastEthernet
followed by the slot/port information.
• For a 1-Gigabit Ethernet interface, enter the keyword
GigabitEthernet followed by the slot/port information.
• For a Port Channel interface, enter the keyword
port-channel
followed by a number:
E-Series Range: 1 to 32 for EtherScale, 1 to 255 for TeraScale and 1 to
512 for ExaScale.
• For a 10-Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet followed by the slot/port information.
hardware_address
Enter a 48-bit hardware MAC address in nn:nn:nn:nn:nn:nn format.
ipv6-address Enter the IPv6 address of the neighbor in the x:x:x:x::x format.
The
:: notation specifies successive hexadecimal fields of zero
