Breakout Modes
The breakout modes for GigaVUE TA Series can be either in card mode or port mode. GigaVUE-TA10 allows card breakout mode whereas GigaVUE-TA25, GigaVUE-TA40, GigaVUE-TA100, GigaVUE-TA100-CXP, GigaVUE-TA200 allows port breakout mode. Refer to Configure the Card Mode – 40Gb/10Gb Support and Configure the Port Mode for further details.
Configure the Card Mode – 40Gb/10Gb Support
GigaVUE-TA10 also enable the first four 40Gb ports (q1..q4). By default, these ports are available for use as single, logical 40Gb ports.
Refer to Configuring the Card Mode on GigaVUE-TA10 and Breakout Panels.
Changing the card mode resets all port and packet distribution settings, therefore, set the card mode during the initial configuration.
Note: The GigaVUE-TA100, GigaVUE-TA100-CXP, GigaVUE-TA200 do not support the card mode, but support the port mode. Refer to Configure the Port Mode. Then refer to Breakout Panels.
Configuring the Card Mode on GigaVUE-TA10
The following card modes are available for the GigaVUE-TA10:
| • | 48x (default) – Four 40Gb ports (q1..q4) and 48 10Gb ports (x1..x48) |
| • | 56x (use with patch panel or breakout cables) – Two 40Gb ports (q3..q4) and 56 10Gb ports. Port q1 is used as x49..x52 on the patch panel. Port q2 is used as x53..56 on the patch panel. |
| • | 64x (use with patch panel or breakout cables) – 64 10Gb ports (x1..x64). Port q1..q4 are connected at the patch panel as follows: |
| • | q1 – x49..x52 |
| • | q2 – x53..x56 |
| • | q3 – x57..x60 |
| • | q4 – x61..x64 |
To specify card modes use the following procedure:
- Deconfigure the card with the following command:
no card slot 1
Note: This removes all port and traffic settings for the system.
- To set the new card mode for GigaVUE-TA10:
card slot 1 mode <48x | 56x | 64x>
The settings for each available mode are summarized in Table 1: 40Gb Port Settings by Card Mode on GigaVUE-TA10:

Notes on GigaVUE-TA10 Card Modes
| • | The default card mode is 48x. |
| • | When a 40Gb port is used as four 10Gb ports, removing the QSFP+ will affect the connections for all four 10Gb ports. For example, removing the QSFP from q1 results in a loss of signal event for x49..x52. |
| • | The q1..q4 40Gb ports include a single link LED on the GigaVUE-TA10 faceplate. When a physical 40Gb interface is used as four 10Gb ports, the 40Gb port LED indicates the status of the first of the four 10Gb ports on the patch panel (for example x49 in the x49..x52 group, x53 in the x53..x56 group, and so on). The other three ports in the group do not affect the link LED for the 40Gb port on the GigaVUE-TA10 faceplate. |
Once the card mode has been configured, refer to Breakout Panels.
Configure the Port Mode
The port breakout modes are as follows:
| • | 4x10G—Specifies the 4x10G port breakout mode. This mode applies to GigaVUE-TA40, GigaVUE-TA100 , GigaVUE-TA200 nodes and and to QSFP28 ports on GigaVUE-TA00-CXP nodes. This mode provides a 4 x 10Gb breakout option for 40Gb ports. |
| • | 4x25G—Specifies the 4x25G port breakout mode. This mode applies to GigaVUE-TA200 nodes. This mode provides a 4 x 25Gb breakout option for 100Gb ports. |
| • | none—Specifies no port breakout mode. This is the default mode for GigaVUE nodes. |
Any of the 100Gb ports on the GigaVUE-TA100 (1/1/c1 to 1/1/c32), the first 32 ports on the GigaVUE-TA200 (1/1/c1 to 1/1/c32), the eight QSFP28 ports (1/1/c21 to 1/1/c28) on the GigaVUE-TA100-CXP can operate at 40Gb with QSFP+ SR transceivers. A 40Gb port can be broken out into four 10Gb ports, called subports.
The subports will all have the same speed (10Gb). Subports will have x1 to x4 appended to their port ID, for example, when port 1/1/c2 on GigaVUE-TA100 is configured to 4x10G mode, the subports will be: 1/1/c2x1, 1/1/c2x2, 1/1/c2x3, and
1/1/c2x4. When port 1/1/c21 on GigaVUE-TA100-CXP is configured to 4x10G mode, the subports will be: 1/1/c21x1, 1/1/c21x2, 1/1/c21x3, and 1/1/c21x4.
In 4x10G mode, the subports can function as network, tool, or hybrid ports, as well as GigaStream port members. Subports on GigaVUE-TA100 and GigaVUE-TA200 can also function as stack ports. In addition, the first 12 and the last 12 ports in GigaVUE-TA40 can also function as stack ports.
| • | The maximum number of 10Gb subports on a GigaVUE-TA100 is 128 (32 x 4). |
| • | The maximum number of 10Gb subports on a GigaVUE-TA100-CXP is 32 (8 x 4). |
| • | The maximum number of 10G subports on a GigaVUE-TA200 is 128 (32 x 4). |
| • | The maximum number of 10G subports on a GigaVUE-TA40 is 96 (24 x 4). |
The 100Gb QSFP28 ports (1/1/c1 to 1/1/c10 and 1/1/c23 to 1/1/c32) on the GigaVUE-TA200 can be broken out into four 25Gb ports, called subports.
The subports will all have the same speed (25Gb). Subports will have x1 to x4 appended to their port ID, for example, when port 1/1/c2 on GigaVUE-TA200 is configured to 4x25G mode, the subports will be: 1/1/c2x1, 1/1/c2x2, 1/1/c2x3, and 1/1/c2x4. The maximum number of 25Gb subports on a GigaVUE-TA200 is 128 (32 x 4).
In 4x25G mode, the subports can function as network, tool, or hybrid ports, as well as GigaStream port members. They cannot function as stack ports.
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 Reference Guide.
Once the port breakout mode has been configured, refer to Breakout Panels.
For further information refer to GigaVUE-OS Compatibility and Interoperability Matrix.
