Configuring a static IPv6 source guard binding entry
Static IPv6 source guard binding entries include global static IPv6 source entries and interface-specific
static IPv6 source guard binding entries.
A global static IPv6 source guard binding entry defines both the source IPv6 address and source MAC
address of packets that can be forwarded, and it takes effect on all interfaces.
Static IPv6 source guard binding entries on an interface take priority over the global static IPv6 source
guard binding entries. An interface first uses the static IPv6 source guard binding entries configured for
the interface to match a received packet. If no match is found, the interface uses the global ones to match
the packet.

Configuring a global static IPv6 source guard binding entry
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure a global
static IPv6 source
guard binding entry.
ipv6 source binding ip-address ipv6-address
mac-address mac-address
No global static IPv6
source guard binding
entry exists.
513B
Configuring a static IPv6 source guard binding entry on an interface
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
The interface-type argument can be Layer 2
Ethernet interface, Layer 3 Ethernet
interface, and VLAN interface.
3. Configure a static IPv6
source guard binding
entry.
ipv6 source binding { ip-address
ipv6-address | ip-address
ipv6-address mac-address
mac-address | mac-address
mac-address } [ vlan vlan-id ]
By default, no static IPv6 source guard
binding entry is configured on an interface.
The vlan vlan-id option is supported in only
Layer 2 Ethernet interface view.
You cannot configure the same static IPv6
source guard binding entry on one interface
multiple times, but you can configure the
same static IPv6 source guard binding entry
on different interfaces.

binding entries (in
standalone mode).
