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 410.
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 509.
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 214.

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. No bandwidth reservations or limits
