Configure the Port Mode

The port breakout modes are as follows:

■

4x10Gb—Specifies the 4x10Gb port breakout mode. This mode applies to GigaVUE-TA100, GigaVUE-TA200, GigaVUE‑TA200E, GigaVUE‑TA25, GigaVUE‑TA25E and GigaVUE‑TA400. This mode provides a 4 x 10Gb breakout option for 40Gb ports.

■

4x25Gb—Specifies the 4x25Gb port breakout mode. This mode applies to GigaVUE-TA200, GigaVUE‑TA200E, GigaVUE‑TA25, GigaVUE‑TA25E and GigaVUE‑TA400 nodes. This mode provides a 4 x 25Gb breakout option for 100Gb ports.

■

4x100Gb—Specifies 4x100Gb port breakout mode. This mode applies to GigaVUE‑TA400 nodes. This mode provides a 4x100Gb breakout option for 400Gb ports

■

none—Specifies no port breakout mode. This is the default mode for GigaVUE TA Series 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 and GigaVUE‑TA200E (1/1/c1 to 1/1/c32), the eight ports on GigaVUE‑TA25 ( 1/1/c1..1/1/c8) or any ports in GigaVUE‑TA400 can operate at 40Gb with QSFP+ SR transceivers.

A 40Gb port can be broken out into four 10Gb ports, called subports. In GigaVUE‑TA25 only the ports c1 and c5 support 4 x10G breakout mode. 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, and1/1/c2x4.

In 4x10Gb mode, the subports can function as network, tool, stack, circuit and hybrid ports. GigaStream port members can be activated in the tool, stack, and hybrid port types. Subports on GigaVUE-TA100, GigaVUE-TA200, GigaVUE‑TA200E and GigaVUE-TA400 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-TA200 and GigaVUE‑TA200E is 128 (32 x 4).

■

The maximum number of 10Gb subports on GigaVUE‑TA25 is 8 ( 2 x 4)

■

The maximum number of 10Gb subports on GigaVUE‑TA25E is 32 ( 8x 4)

■

The maximum number of 10Gb subports on a GigaVUE‑TA400 is 128 (32 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, GigaVUE‑TA200E and GigaVUE‑TA25 can be broken out into four 25Gb ports, called subports. In GigaVUE‑TA25 only the ports c1 and c5 support 4 x25Gb breakout mode.

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 and GigaVUE‑TA200E is 128 (32 x 4).

■

In GigaVUE‑TA25 the maximum number of 25Gb subports is 8 ( 2x 4)

■

The maximum number of 10Gb subports on GigaVUE‑TA25E is 32 ( 8x 4)

■

The maximum number of 25Gb subports on a GigaVUE‑TA400 is 128 (32 x 4).

In 4x25Gb mode, the subports can function as network, tool, stack, circuit and hybrid ports. GigaStream port members can be activated in the tool, stack, and hybrid port types.

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.
