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 339.

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 "IPv6 Interfaces" on page 105.

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 a spin-off of the 802.1Q (VLANs)

standard. 802.1p establishes eight levels of priority, similar to the IP

Precedence IP Header bit-field.
For more information about QoS, see "Quality of Service" on page 423.

Advanced QoS

Frames that match an ACL and were permitted entrance are implicitly

labeled with the name of the ACL that permitted their entrance. Advanced

mode QoS actions defined in network policies can then be applied to these

flows.
The switch can set DSCP values and map IPv6 DSCP to egress queues in the

same way it does for IPv4. The switch detects IPv6 frames by the IPv6 ether-

type.
For more information about Advanced QoS, see "QoS Advanced Mode" on

page 439.
