Gigamon GigaVUE-HC3, Hardware Installation Manual

Page: 33 / 142

Introducing the GigaVUE-HC3 33
is configured to 4x25G mode, the subports will be: 1/1/c2x1, 1/1/c2x2, 1/1/c2x3, and
1/1/c2x4.
In 4x25G mode, the subports can function as network, tool, or hybrid ports, as well as
GigaStream port members.
The maximum number of 25Gb subports on a SMT-HC3-C05 module is 20 (5 ports per
module x 4 subports per port).

Each port can only have one mode.
There are rules for configuring parent ports and subports. For more information, refer
to the
port command in the reference section of the GigaVUE-OS CLI User’s Guide .
Once the port breakout mode has been configured, refer to Breakout Panels on
page 44 .
BPS-HC3-C25F2G Module
The BPS-HC3-C25F2G module is a bypass combo module with two 100Gb/40Gb SR4
inline network port pairs and sixteen 10Gb SFP+ and SFP+ Copper port cages. The
inline network ports support physical bypass at speeds of 100Gb or 40Gb. A 4x10Gb
port breakout mode is supported offering physical bypass at 10Gb.
Security tools such as firewall and intrusion detection/protection systems are often
connected inline on production networks, with traffic flowing from the network segment
through the tool and then back onto the production network.
The GigaVUE-HC3 offers physical and logical inline bypass. Physical bypass provides
automatic failover protection in the case of a power failure. The bypass combo module
provide the physical bypass function. As it applies to a single pair of inline network
ports, the physical bypass function is as follows:
• When the module is not powered, (either the entire node is powered down or the
module is removed from the node), the inline network port pair is in the physical
bypass mode. That means that traffic is exchanged directly between network Port A
and network Port B of the inline network pair.
• When the module is powered, the mode (inline or bypass) of the inline network port
pair is controlled through software. In the physical bypass mode, the inline network
port pair behaves exactly as if the module was not powered. In the inline mode, the
inline network port pair behaves as any other inline network port pair configured for
working with an inline tool. For information about configuring inline modes, refer to
the “inline-network” section of the
GigaVUE-OS CLI User’s Guide.
Before installing the BPS-HC3-C25F2G module, the GigaVUE-HC3 must be running
software version 5.1.01 or higher. Dual speed (100Gb or 40Gb) support is added
starting in software version 5.2. The 4x10Gb port breakout mode is added starting in
software version 5.3.

The BPS-HC3-C25F2G module does not support 1Gb.
The sixteen 10Gb ports in the BPS-HC3-C25F2G module can be used as network,
tool, hybrid, stack, inline-network, or inline-tool ports.
