mac-address mac-address: Specifies the MAC address for the static source guard. The MAC address is
in the format H-H-H but cannot be all 0s, all Fs (a broadcast MAC address), or a multicast MAC address.
all: Specifies all global static IPv6 source guard binding entries.
Usage guidelines
A global static IPv6 source guard binding entry takes effect on all interfaces.
The maximum number of global static IPv6 source guard binding entries that can be configured depends
on your device model.
Examples
# Configure a global static IPv6 source guard binding entry to allow only the packets with source IPv6
address 2001::1 and source MAC address 0002-0002-0002 to pass.
<Sysname> system-view
[Sysname] ipv6 source binding ipv6-address 2001::1 mac-address 0002-0002-0002

Parameters
ip-address: Filters packets by source IPv6 addresses. With this keyword specified, the IP source guard
function on the interface filters a received packet by using source IPv6 addresses of the IPv6 source guard
binding entries. If a match is found, the interface forwards the packet. Otherwise, the interface discards
the packet.
ip-address mac-address: Filters packets by source IPv6 addresses and source MAC addresses. With this
keyword specified, the IP source guard function on the interface filters a received packet by using source
IPv6 addresses and source MAC addresses of dynamic IPv6 source guard binding entries. If both the
source IPv6 address and source MAC address of the packet match an entry, the interface forwards the
packet. Otherwise, the interface discards the packet.
