Release 9.4.2 Release Notes

Issue 1, May 2009 Page 11

Hardware series

Product

P11 or P10

Note: No significant difference between DES and AES

1: Links with a P9 module on one end and a P10 or P11 module on the other

perform between 3200 and 3500 pps

Section 9, Performance Benchmarking Process, on page 31 describes the benchmarking process

used to measure packets per second and discusses the meaning and limitations of the

benchmark.

2.3 SUPPORT FOR P11 HARDWARE

5.2-GHz and 5.4-GHz P11 modules require, at a minimum, Release 9.4 and will initially ship with

Release 9.4 or Release 9.4.1 installed. These modules should be upgraded to Release 9.4.2

before being deployed.

5.7-GHz P11 modules require, at a minimum, Release 9.3 and will initially ship with Release 9.3

installed.

P11 modules exhibit performance similar to P10, as shown in Table 3 on page 10.

2.3.1 Mixing Hardware Vintages

P11 APs and SMs can be mixed with other hardware vintages in a sector. P11 BHs can be mixed

with P9 and P10 BHs on a link.

2.3.2 Mixing Software Releases

To smooth the transition to P11 hardware, mixing Releases 9.0 and 9.4.2, or Releases 9.0 and

9.3, in a sector is supported. For example, if you purchase an SM and it is P11 hardware running

Release 9.3 from the factory, it can be run in a sector with an AP and other SMs running Release

9.0. Or, if you purchase an AP and it is P11 hardware running Release 9.4.2 from the factory, it

can be run with a sector of SMs running Release 9.0.

Before deploying P11 hardware into a sector, existing APs and SMs in the sector should first be

upgraded to at least Release 9.0.
