Trunking
NOTE
The term “trunking” in an Ethernet network refers to the use of multiple network links (ports) in
parallel to increase the link speed beyond the limits of any one single link or port, and to increase
the redundancy for higher availability.
802.1ab Link Layer Discovery Protocol (LLDP) is used to detect links between neighboring switches
so that a trunk can be configured between the neighboring switch and the Brocade 8000 CEE
switch. The Data Center Bridging (DCB) Capability Exchange Protocol (DCBX) extension is used to
identify a CEE-capable port on a neighboring switch. For detailed information on configuring LLDP
and DCBX, see “Configuring LLDP using the CEE CLI” on page 79.
The 802.3ad Link Aggregation Control Protocol (LACP) is used to combine multiple links to create a
trunk with the combined bandwidth of all the individual links. For detailed information on
configuring LACP, see “Configuring Link Aggregation using the CEE CLI” on page 67.
Flow Control
802.3x Ethernet pause and Ethernet Priority-based Flow Control (PFC) are used to prevent dropped
frames by slowing traffic at the source end of a link. When inbound traffic to a Brocade 8000 CEE
port reaches a certain level, there could be dropped frames because of the amount of traffic. When
Ethernet pause is enabled, pause frames are sent to the traffic source. Similarly, when PFC is
enabled, there is no frame drop; pause frames are sent to the source switch.
For detailed information on configuring Ethernet pause and PFC, see “Configuring QoS using the
CEE CLI” on page 103.
