Configure PC Port—The 802.1X standard does not take into account the use
of VLANs and thus recommends that only a single device be authenticated to
a specific switch port. However, some switches (including Cisco Catalyst
switches) support multi-domain authentication. The switch configuration
determines whether you can connect a PC to the phone PC port.
Enabled—If you are using a switch that supports multi-domain
–
authentication, you can enable the PC port and connect a PC to it. In this
case, Cisco Unified IP Phones support proxy EAPOL-Logoff to monitor
the authentication exchanges between the switch and the attached PC.
For more information about IEEE 802.1X support on the Cisco Catalyst
switches, refer to the Cisco Catalyst switch configuration guides at:
http://www.cisco.com/en/US/products/hw/switches/tsd_products_
support_category_home.html
Disabled—If the switch does not support multiple 802.1X-compliant
–
devices on the same port, you should disable the PC Port when 802.1X
authentication is enabled. See the
on page 4-22 for more information. If you do not disable this port and
subsequently attempt to attach a PC to it, the switch will deny network
access to both the phone and the PC.
Configure Voice VLAN—Because the 802.1X standard does not account for
VLANs, you should configure this setting based on the switch support.
Enabled—If you are using a switch that supports multi-domain
–
authentication, you can continue to use the voice VLAN.
Disabled—If the switch does not support multi-domain authentication,
–
disable the Voice VLAN and consider assigning the port to the native
VLAN. See the "Security Configuration Menu" section on page 4-22
more information.
Enter MD5 Shared Secret—If you disable 802.1X authentication or perform
a factory reset on the phone, the previously configured MD5 shared secret is
deleted. See the "802.1X Authentication and Status" section on page 4-36
more information.
