Unusual Network Activity
authentication request.
If the RADIUS server configuration for authenti-
cating the client includes a VLAN assignment, ensure that the VLAN exists as
a static VLAN on the switch. See "How 802.1x Authentication Affects VLAN
Operation" in the
Access Security Guide
for your switch.
During RADIUS-authenticated client sessions, access to a VLAN on the
port used for the client sessions is lost.
If the affected VLAN is config-
ured as untagged on the port, it may be temporarily blocked on that port during
an 802.1x session. This is because the switch has temporarily assigned another
VLAN as untagged on the port to support the client access, as specified in the
response from the RADIUS server. See "How 802.1x Authentication Affects
VLAN Operation" in the
Access Security Guide
for your switch.
The switch appears to be properly configured as a supplicant, but
cannot gain access to the intended authenticator port on the switch
to which it is connected.
If
aaa authentication port-access
is configured for
Local, ensure that you have entered the local
login
(operator-level) username
and password of the authenticator switch into the
identity
and
secret
parame-
ters of the supplicant configuration. If instead, you enter the enable (manager-
level) username and password, access will be denied.
The supplicant statistics listing shows multiple ports with the same
authenticator MAC address.
The link to the authenticator may have been
moved from one port to another without the supplicant statistics having been
cleared from the first port. Refer to the "Note on Supplicant Statistics" in the
Access Security Guide
for your switch.
The
show port-access authenticator <
port-list
>
command shows one or more
ports remain open after they have been configured with
control
unauthorized
.
802.1x is not active on the switch. After you execute
aaa port-
access authenticator active
, all ports configured with
control unauthorized
should be listed as
Closed
.
