Parameters

pool pool-name: Displays IPv6 prefix binding information for the DHCPv6 address pool specified by its name, a case-insensitive string of 1 to 63 characters. If you do not specify a DHCPv6 address pool, this command displays IPv6 prefix binding information for all DHCPv6 address pools.

prefix prefix/prefix-len: Displays binding information for the specified IPv6 prefix. The value range for the prefix length is 1 to 128. If you do not specify an IPv6 prefix, this command displays binding information for all IPv6 prefixes.

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, this command displays binding information about IPv6 prefixes for the public network.

Table 66: Command output

Field	Description
IPv6 prefix	IPv6 prefix assigned.
Type	Prefix binding types: Static(F)—Free static binding whose IPv6 prefix has not been assigned. Static(O)—Offered static binding whose IPv6 prefix has been selected and sent by the DHCPv6 server in a DHCPv6-OFFER packet to the client. Static(C)—Committed static binding whose IPv6 prefix has been assigned to the client. Auto(O)—Offered dynamic binding whose IPv6 prefix has been dynamically selected by the DHCPv6 server and sent in a DHCPv6-OFFER packet to the DHCPv6 client. Auto(C)—Committed dynamic binding whose IPv6 prefix has been dynamically assigned to the DHCPv6 client. Auto(Z)—Zombie dynamic binding whose IPv6 prefix has been dynamically assigned to the DHCPv6 client. The binding becomes zombie because the prefix in the prefix pool goes invalid after a configuration recovery, for example, after a switchover from the backup to the master.
Pool	Address pool.
Lease-expiration	Time when the lease of the IPv6 prefix will expire. If the lease will expire after the year 2100, this field displays Expires after 2100. For an unassigned static binding, this field displays Not available.
Client	IPv6 address of the DHCPv6 client. For an unassigned static binding, this field is blank.
DUID	Client DUID.
IAID	Client IAID. For an unassigned static binding without IAID, this field displays N/A.
Preferred lifetime	Preferred lifetime in seconds of the IPv6 prefix.
valid lifetime	Valid lifetime in seconds of the IPv6 prefix.
Expires at	Time when the lease of the prefix will expire. If the lease expires after the year 2100, this field displays Expires after 2100.
