debug ipv6 cache
Displays information when an IPv6 cache entry is added, deleted, or updated. The IPv6 cache contains an IPv6
host table that has indices to the next hop gateway and the router interface on which the route was learned.
EXAMPLE:
ProCurveRS debug ipv6 cache
After you enter this command, messages such as the following appear at the destination specified for debugging
output. You can turn off these messages with the no debug ipv6 cache command.
IPv6RT0: Deleted cache for fe80::204:80ff:fe2c:c048 on port 3/9 Local
IPv6RT0: Deleted cache for 3000:1::2 on port 3/9 Local
IPv6RT0: update cache entries for parent route 3000:1::/6 route 3000:1::/64
IPv6RT0: Added cache for 3000:1::2 on port 3/9 Local
IPv6RT0: Added cache for fe80::204:80ff:fe2c:c048 on port 3/9 Local
Syntax: [no] debug ipv6 cache
Possible values: N/A
Default value: N/A
debug ipv6 icmp
Displays information when an HP device that supports IPv6 receives and transmits ICMP request, response, error,
and redirect packets.
EXAMPLE:
ProCurveRS debug ipv6 icmp
After you enter this command, messages such as the following appear at the destination specified for debugging
output. You can turn off these messages with the no debug ipv6 icmp command.
ICMPv6:Sending Echo Request to 3000:1::6, length 24
ICMPv6:Received Echo Reply from 3000:1::6, length 24
Syntax: [no] debug ipv6 icmp

Default value: N/A
debug ipv6 nd
Displays information when an HP device that supports IPv6 sends and receives neighbor solicitation and
advertisement messages, which verify the existence of a new neighbor or an existing neighbor that has become
unreachable.
EXAMPLE:
ProCurveRS debug ipv6 nd
After you enter this command, messages such as the following appear at the destination specified for debugging
output. You can turn off these messages with the no debug ipv6 nd command.
ICMPv6-ND: STALE->DELAY: 3000:1::6 on 3/9
ICMPv6-ND: Received NS for 3000:1::2 on 3/9 from 3000:1::6
ICMPv6-ND: Sending NA for 3000:1::2 on 3/9
