• The priority of untagged packets is assigned according to the remapped value of priority 0 trac in the RADIUS-based table. For
example, in the following remapping table, untagged packets are tagged with priority 2:

• After being re-tagged by dynamic CoS for 802.1X, packets are forwarded in the switch according to their new CoS priority.
• When a supplicant logs o from an 802.1X authentication session, the dynamic CoS table is deleted or reset. When an 802.1x session is
re-authenticated, the previously assigned CoS table is retained through the re-authentication process. If the re-authentication fails, the
CoS table is deleted. If the re-authentication is successful and the authentication server does not include a CoS table in the AUTH-
ACCEPT packet, the previously assigned CoS table MUST be deleted. If the re-authentication is successful and the server sends a CoS
table, the old CoS table is overwritten with the new one.
• If multi-supplicant authentication mode is enabled on a port, you can congure a CoS mapping table for specied MAC addresses in the
RADIUS server. Dell Networking OS then maintains a per-MAC CoS table for each port, and marks the priority of all trac originating
from a congured MAC address with the corresponding table value.
• To display the CoS priority-mapping table provided by the RADIUS server and applied to authenticated supplicants on an 802.1X-
enabled port, enter the show dot1x cos-mapping interface command.
