dhcpv6 snooping bind-table static

Function

The dhcpv6 snooping bind-table static command binds the IPv6 address, MAC address, VLAN, and interface to DHCPv6 snooping.

The undo dhcpv6 snooping bind-table static command deletes the static binding between the IPv6 address, MAC address, VLAN, and interface in DHCPv6 snooping.

By default, the static binding relationship of VLAN, IPv6 address and MAC address is not configured.

Format

dhcpv6 snooping bind-table static { ipv6-address ipv6Addr [ mac-address macAddr ] | ipv6-prefix ipv6-prefix-mask } [ vlan vlanId [ ce-vlan ceVlanId ] ]

undo dhcpv6 snooping bind-table static { ipv6-address ipv6Addr [ mac-address macAddr ] | ipv6-prefix ipv6-prefix-mask } [ vlan vlanId [ ce-vlan ceVlanId ] ]

Parameters

Parameter	Description	Value
ipv6-address ipv6Addr	Specifies the IPv6 address of a user.	The value is a 32-digit hexadecimal number in the format of X:X:X:X:X:X:X:X.
mac-address macAddr	Specifies the MAC address of a user.	The value is a 12-digit hexadecimal number, in the format of H-H-H. Each H is 4 digits.
ipv6-prefix ipv6-prefix-mask	Specifies the IPv6 prefix address and IPv6 prefix length.	IPv6 prefix address: a 32-bit hexadecimal number in X:X:X:X:X:X:X:X format. IPv6 prefix length: The value is an integer ranging from 16 to 128.
vlan vlanId	Specifies a VLAN ID.	The value is an integer ranging from 1 to 4094.
ce-vlan ceVlanId	Specifies a user-side VLAN ID.	The value is an integer ranging from 1 to 4094.

Usage Guidelines

Usage Scenario

After the dhcpv6 snooping bind-table static command is run, the static bindings between IPv6 addresses, MAC addresses, VLANs, and interfaces in DHCPv6 snooping are generated. Dynamic entries in the DHCPv6 snooping binding table do not need to be configured. After DHCPv6 snooping is enabled, dynamic entries in the DHCPv6 snooping binding table are automatically generated. Static entries, however, need to be configured. A maximum of 4096 static DHCPv6 snooping binding entries can be configured on each interface.

Example

# Bind the IPv6 address to the MAC address statically on GE0/1/0.
