Brocade VDX 8770-4 line cards
This section provides general information on the line cards. For specific information on line card
ports and port hardware, refer to
Chapter 1, “Brocade VDX 8770-4 Overview” . Table 1 summarizes
the line cards that are available for the Brocade VDX 8770-4.

Breakout mode
Quad SFP (QSFP) 40 Gbps ports on 12x40 GbE and 27x40 GbE line cards can be configured in
breakout mode to create four separate 10 Gbps interfaces. You can administer and operate these
interfaces as any other SFP port. Special breakout cables provide a connection to the 40 Gbps
QSFP port and to four 10 Gbps SFP ports on another switch. Twinax active copper cables at 1, 3,
and 5 meters and fiber-optic breakout cables are supported.
NOTE
While 40 GbE ports are in breakout mode, port status (individual or as a group) cannot be
determined from the port LED state color.
For more information on configuring breakout mode, refer to the Network OS Administrator’s
Guide.
Trunking
Network OS supports Brocade trunks (hardware-based link aggregation groups, or LAGs). These
trunks are dynamically formed between two adjacent switches with connected interswitch link (ISL)
ports unless trunking is disabled on connecting ports. Traffic is evenly distributed along all links in
a trunk. For more information on Brocade Trunking and enabling and disabling trunking, refer to the
“Configuring Brocade VCS Fabrics” chapter in the Network OS Administrator’s Guide.
Trunking is supported on GbE interface ports of all line cards
Port groups
Port groups are established for trunking on supported line cards. To successfully form a trunk from
line card ports to another switch, select ports from same line card port group and configure each
port to operate at the same speed. Following are trunk and port group specifications for supported
line cards:
