ip ip-address: Displays binding information about the specified assigned IP address. If you do not
specify an IP address, this command displays binding information about all assigned IP addresses.
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 assigned IP addresses for the public network.
pool pool-name: Displays binding information about assigned IP addresses in the specified address
pool. The pool name is a case-insensitive string of 1 to 63 characters. If you do not specify an
address pool, this command displays binding information about assigned IP addresses in all address
pools.
Usage guidelines
The binding information can be used by other security modules only when the DHCP server is
configured on the gateway of DHCP clients.
If the lease deadline exceeds the year 2100, the lease expiration time is displayed as After 2100.
