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.

DHCP Clients
DHCP enables additional setup parameters to be received from a network
server upon system startup. DHCP service is an on-going process.

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
are established or enforced. 802.1p is taken from the 802.1Q (VLANs)
standard. 802.1p establishes eight levels of priority, similar to the IP
Precedence IP Header bit-field.

Network Administration: Quality of
Service .
TCP Congestion Avoidance
The TCP Congestion Avoidance feature activates an algorithm to prevent
TCP global synchronization during congestions. TCP global synchronization
can occur when packets are dropped all at once during congestion. As a result,
it can unexpectedly synchronize multiple TCP hosts to reduce their
transmission during congestion and restart the transmission when the
congestion eases.
