CoS messages also include Quality of Service (QoS) events. The QoS feature classifies and prioritizes traffic throughout a network, establishing an end-to-end traffic priority policy to manage available bandwidth and improve throughput of important data. Dynamic Configuration Arbiter (DCA) determines the client- Access Security Guide specific parameters that are assigned in an authentication session. Dynamic Host Configuration Protocol (DHCP) server configuration: Switch is automatically configured from a DHCP (Bootp) server, including IP address, subnet mask, default gateway, Timep Server address, and TFTP server address. Management and Configuration Guide DHCP for IPv6 prefix assignment IPv6 Configuration Guide Download operation for copying a software version or files to Management and Configuration Guide the switch. Direct Access Memory (DMA): Transmits and receives - packets between the CPU and the switch. Not used for logging messages in software release K.13.xx. Fault Detection facility, including response policy and the Management and Configuration Guide sensitivity level at which a network problem should generate an alert.
