Link Aggregation Up to 32 Aggregated Links may be defined, each with up to eight member ports, to form a single Link Aggregated Group (LAG). This enables: • Fault tolerance protection from physical link disruption • Higher bandwidth connections • Improved bandwidth granularity • High bandwidth server connectivity A LAG is composed of ports with the same speed, set to full-duplex operation. For more information, see "LAG Configuration" on page 403. Link Aggregation and LACP LACP uses peer exchanges across links to determine, on an ongoing basis, the aggregation capability of various links, and continuously provides the maximum level of aggregation capability achievable between a given pair of devices. LACP automatically determines, configures, binds, and monitors the port binding within the system. For more information, see "Link Aggregation" on page 500. BootP and DHCP Clients DHCP enables additional setup parameters to be received from a network server upon system startup. DHCP service is an on-going process. DHCP is an extension of BootP. For more information, see "DHCP IPv4 Interface" on page 207. Quality of Service Features Class of Service 802.1p Support The IEEE 802.1p signaling technique is an OSI Layer 2 standard for marking and prioritizing network traffic at the data link/MAC sub-layer. 802.1p traffic is classified and sent to the destination.
