Remarks
2. Enable 802.1X globally.
dot1x
Optional.
By default, 802.1X is disabled globally.
3. Enter interface view.
interface interface-type
interface-number
The term "interface" collectively refers to
the following types of ports and interfaces:
Bridge mode (Layer 2) Ethernet ports,
VLAN interfaces, and port groups.
4. Enable 802.1X on the
interface.
dot1x
Optional.
By default, 802.1X is disabled on the
interface.
5. Enable the 802.1X IP freezing
function.
dot1x user-ip freeze
Optional.
By default, this function is disabled. A port
saves the IP addresses of 802.1X users and
updates the IP addresses if 802.1X users
change their IP addresses.
6. Enable the interface to
generate 802.1X-based
dynamic IPv4 source guard
binding entries.
ip verify source dot1x
Optional.
By default, an interface does not generate
802.1X-based dynamic IPv4 source guard
binding entries.
7. Configure IPv4 source guard
on the interface.
ip verify source
{ ip-address | ip-address
mac-address |
mac-address }
Not configured by default.
NOTE:
lthou
h dynamic IPv4 source guard binding entries are
enerated based on DHCP entries, the numbe
of dynamic IPv4 source guard binding entries is not necessarily the same as that of the DHCP entries.
Configuring a static IPv4 source guard binding entry
Static IPv4 binding entries take effect on an interface only when the interface is configured with the IPv4
source guard feature (see "Configuring IPv4 source guard on an interface")
.
You can configure global static and interface-specific static IPv4 source guard binding entries. Global
static binding entries take effect on all interfaces configured with the IPv4 source guard feature.
Interface-specific static binding entries take priority over global static binding entries. An interface first
uses the static binding entries on the interface to match packets. If no match is found, the interface uses
the global binding entries.
