Stacking compatibility

You can stack the BPS 2000 up to 8 units high. There are two types of stacks:

• Pure BPS 2000—This stack has only BPS 2000 switches. It is sometimes

referred to as a pure stack. The stack operational mode for this type of stack is

Pure BPS 2000 Mode.

• Hybrid—This stack has a combination of BPS 2000 switches and BayStack*

450 and/or BayStack 410 switches. It is sometimes referred to as a mixed

stack. The stack operational mode for this type of stack is Hybrid Mode.

When you work with the BPS 2000 in standalone mode, you should ensure that

the stack operational mode shows Pure BPS 2000 Mode, and does not show

Hybrid Mode.

All BPS 2000 switches in the stack must be running the identical version of

software, and all the BayStack switches must be running the identical version of

software.

When you are working with a mixed stack, you must ensure that the

Interoperability Software Version Numbers (ISVN) are identical. That is, the

ISVN number for the BayStack 450 switch and BayStack 410 switch must have

the same ISVN as the BPS 2000. If the ISVNs are not the same, the stack does not

operate.

In sum, the stacking software compatibility requirements are as follows:

• Pure BPS 2000 stack—All units must be running the same software version.

Note: To access the software version 1.2 features in a mixed stack, you

must access a BPS 2000 unit. Additionally:

- only 64 VLANS are available in a mixed stack

- multiple STG support is not available in a mixed stack
