Purpose
CLI Command
Set the minimum interval for neighbor solicitation
retransmissions.
configure interface cable-mac <mac> ipv6 nd
ns-interval <int> [no]
Set the date and time when the prefix expires.
configure interface cable-mac <mac> ipv6 nd prefix
<word> [<valid_lifetime>] [<preferred_lifetime>
[off-link] [no-autoconfig] [autoconfig] [no]
Configure the IPv6 neighbor discovery (ND) cache
prefix for the cable interface not to expire.
configure interface cable-mac <mac> ipv6 nd prefix
<word> infinite [off-link] [no-autoconfig]
Display the IPv6 ND cache entry for an IPv6 address or
optional interface.
show ipv6 neighbors [<ipv6-address>]
[<interface-type>] [<interface-number>]
Display the contents of the IPv6 route table entries
for an IPv6 address or interface.
show ipv6 route [vrf <vrf-name>] [detail] [<word>]
<ipv6-address> [connected] [local] [netmgmt] [static]
[isis] [ospf]
To display the IPv6 Neighbor Discovery (ND) cache entries for an interface:
show ipv6 neighbors [<ipv6-address>] [<interface-type>] [<interface-number>]
show ipv6 neighbors tenGigaethernet 17/10
Sample output:
ND cache aging has been disabled

2 FE80::216:9CFF:FE6F:F0C0 0016.9c6f.f0c0 Dynamic Active TenGg 17/10
Another CLI command is used to obtain IPv6 ND information for an IPv6 address. The State values are the same as for the
previous command.
show ipv6 neighbors [<ipv6-address>]
Sample output:
ND cache timeout is 1200 seconds
