BPS-HC1-D25A24 Bypass Combo Module
There is one 10Gb bypass combo module as follows:
Before installing the BPS-HC1-D25A24 Bypass Combo Module, the GigaVUE‑HC1 must be running software version 5.0 or higher.
For internal transceiver and loss summary specifications, refer to Bypass Combo Module Specifications.
Bypass Combo Modules
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‑HC1 offers physical and logical inline bypass. Physical bypass provides automatic failover protection in the case of a power failure. The bypass combo modules 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. |
Features of the 10Gb Bypass Combo Module
The 10Gb bypass combo module has the following features:
|
•
|
Two inline network port pairs that pass traffic bi-directionally. |
|
•
|
Port pairs that offer optical protection switch for physical bypass. |
|
•
|
Four regular SFP ports that can operate at 1Gb, and SFP+ and SFP+ Copper ports that can operate at 10Gb. These ports can be configured as any port type. |
|
•
|
A mode to select either bypass or inline. |

Module Status LEDs
The following module status LEDs are located on the front of the bypass combo module:
|
•
|
RDY is the Ready LED. It has the following states: |
|
•
|
RED indicates system booting or module down |
|
•
|
GREEN indicates normal condition |
|
•
|
POWER is the Power LED. It has the following state: |
|
•
|
GREEN indicates the module is receiving power |
Port Status LEDs
The SFP+ Port Status LEDs have the following states:
|
•
|
Off indicates that the port is disabled or the link is down |
|
•
|
GREEN indicates that the link is established |
Ports
You can configure any two of the four 10Gb ports as an inline tool port pair and connect an inline tool to them.
For tool ports, you can also use ports on any module in the chassis, including ports on other bypass combo modules or ports on other GigaVUE‑HC1 modules.
Ports have the following labels: X1 to X4. In the CLI, these ports are referred to as:
x1 to x4.
Inline Network Ports
Connect inline networks to the inline network ports. The inline network ports have built-in protection for power down.
The inline network status LEDs have the following labels:
|
•
|
A1—Inline network LED A (for network 1 through network 2) |
|
•
|
B1—Inline network LED B (for network 1 through network 2) |
|
•
|
M1—Mode LED (on is inline and off is bypass) |
|
•
|
A2—Inline network LED A (for network 1 through network 2) |
|
•
|
B2—Inline network LED B (for network 1 through network 2) |
|
•
|
M2—Mode LED (on is inline and off is bypass) |
Note: In the CLI, the inline network ports are referred to as x5 to x8.
Using Bypass Combo Modules for Gigamon Resiliency for Inline Protection
Gigamon Resiliency for Inline Protection (GRIP)™ is an inline bypass solution that connects two GigaVUE‑HC1 nodes together so that one node provides high availability to the other node when there is a loss of power. This redundant arrangement of two GigaVUE‑HC1 nodes maintains traffic monitoring by inline tools when one of the nodes is down.
GRIP™ makes use of the bypass protection switch relays for protected inline networks on GigaVUE‑HC1 nodes. The bypass combo modules can provide physical protection for protected pairs of optical inline network ports required by the GRIP solution.
To configure the GRIP solution, the GigaVUE‑HC1 must be running GigaVUE-OS version 5.0 or higher. For solution and configuration information, refer to the chapter “Configuring Inline Bypass Solutions” in the GigaVUE-OS-CLI Reference Guide.
