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 and GigaVUE-TA200 nodes 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), or 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.
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.
The maximum number of 25Gb subports on a GigaVUE-TA200 is 128 (32 x 4).
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.
