Using the T-Flow Redundant Management Module

The T-Flow Redundant Management Module version 1 (T-Flow) is a redundant management module for HP 9300
series Chassis devices. The T-Flow supports all of the features supported by Management 2 and 4 modules, but
enhances feature performance using new hardware architecture.
NOTE: This chapter does not describe how to configure redundancy parameters. See "Using Redundant
Management Modules" on page 3-1.

Overview

The T-Flow provides enhanced performance using distributed processing among multiple CPUs. The multiple
CPUs enable the T-Flow to perform the following in hardware:
• Process Access Control Lists (ACLs)
• Perform Policy-Based Routing (PBRs)
• Perform Network Address Translation (NAT)
• Collect statistics and export them for NetFlow-based accounting and billing
Figure 4.1 shows the T-Flow.

The T-Flow does not have network interfaces but does have a serial management interface. In addition, the
module has status LEDs for its Management Processor (MP) and T-Flow Switching Processor (TSPs), described
in "Management and Co-Processing CPUs" on page 4-1 and "Status LEDs" on page 4-13.

Management and Co-Processing CPUs

The T-Flow contains four CPUs:
• One MP (Management Processor) – The MP performs management functions for the entire chassis.
