interface-number
The interface-type argument can
be Layer 2 Ethernet interface,
Layer 3 Ethernet interface, and
VLAN interface.
3. Enable the IPv4 source guard
function.
ip verify source { ip-address |
ip-address mac-address |
mac-address }
By default, the function is disabled
on an interface.
If you configure this command on
an interface multiple times, the
most recent configuration takes
effect.
291B
Configuring a static IPv4 source guard binding entry
Static IPv4 source guard binding entries include global static IPv4 source entries and interface-specific
static IPv4 source guard binding entries.
A global static IPv4 source guard binding entry defines both the source IP address and source MAC
address of packets that can be forwarded, and it takes effect on all interfaces.
Static IPv4 source guard binding entries on an interface take priority over the global static IPv4 source
guard binding entries. An interface first uses the static IPv4 source guard binding entries configured for
the interface to match a received packet. If no match is found, the interface uses the global entries to
match the packet.
