display dhcpv6 snooping user-bind

Function

The display dhcpv6 snooping user-bind command displays the DHCPv6 snooping binding table.

Format

display dhcpv6 snooping user-bind { { interface interface-type interface-number | ipv6-address { ipv6-address | all } | mac-address mac-address | vlan vlan-id } ^* | confirm-client | all } [ verbose ]

display dhcpv6 snooping user-bind ipv6-prefix { prefix/prefix-length | all } [ verbose ]

Parameters

Parameter	Description	Value
interface interface-type interface-number	Displays the binding entry mapping a specified interface. interface-type specifies the interface type. interface-number specifies the interface number.	-
ipv6-address ipv6-address	Displays the binding entry mapping a specified IPv6 address.	The address is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
mac-address mac-address	Displays the binding entry mapping a specified MAC address.	The value is in hexadecimal notation.
vlan vlan-id	Displays the binding entry mapping a specified VLAN ID.	The value is an integer that ranges from 1 to 4094.
ipv6-prefix	Displays an IPv6 suffix binding entry.	-
prefix/prefix-length	Displays the binding entry mapping a specified IPv6 prefix.	prefix is a 32-digit hexadecimal number, in the format of X:X::X:X. prefix-length is an integer that ranges from 1 to 128.
confirm-client	Displays the DHCPv6 snooping binding entries generated using DHCPv6 Confirm packets.	-
all	Displays all entries in the binding table.	-
verbose	Displays detailed information about the binding table. If the parameter is not specified, brief information about the binding table is displayed.	-

Usage Guidelines

After DHCP snooping is enabled, the device generates a DHCP snooping binding table by listening to DHCP Request messages and Reply messages. A binding entry contains the MAC address, IP address, number of the interface connected to the DHCP client, and VLAN ID. You can run the display dhcpv6 snooping user-bind command to view the DHCPv6 snooping binding table.

If prefix delegation (PD) users exist on the network, the device generates an IPv6 prefix binding entry. The display dhcpv6 snooping user-bind ipv6-prefix command displays IPv6 prefix binding entries.
