This enables:• Fault tolerance protection from physical link disruption• Higher bandwidth connections• Improved bandwidth granularity• High bandwidth server connectivityA LAG is composed of ports with the same speed, set to full-duplexoperation.For more information, see "LAG Configuration" on page 410.Link Aggregation and LACPLACP uses peer exchanges across links to determine, on an ongoing basis, theaggregation capability of various links, and continuously provides themaximum level of aggregation capability achievable between a given pair ofdevices. LACP automatically determines, configures, binds, and monitors theport binding within the system.For more information, see "Link Aggregation" on page 509.BootP and DHCP ClientsDHCP enables additional setup parameters to be received from a networkserver upon system startup. DHCP service is an on-going process. DHCP is anextension of BootP.For more information, see "DHCP IPv4 Interface" on page 214.Quality of Service FeaturesClass of Service 802.1p SupportThe IEEE 802.1p signaling technique is an OSI Layer 2 standard for markingand prioritizing network traffic at the data link/MAC sub-layer. 802.1p trafficis classified and sent to the destination.
