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

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 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.
• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE
followed by the slot/port information.
hardware_address

Version 8.3.7.0 Introduced on S4810
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
cpu
Enter the keyword cpu followed by either rp1 or rp2 (Route
Processor 1 or 2), optionally followed by an IPv6 address to display
the IPv6 neighbor entries stored on the designated RP.
