Cisco MDS 9000 Family Port Analyzer Adapter Installation and Configuration Note
OL-9077-01
Selecting Truncate Mode
In MNM, the adapter transmits a fixed 288-byte Ethernet frame that contains debug information for your
use or for technical support calls. When calling technical support, also know the version number of the
adapter . There are two versions of PAA, PAA-1 and PAA-2. If you see the Original Packet Length field
in the debug information (highlighted in Figure 5), you are using a PAA-2. If this field is not present,
you are using PAA-1.
Note The Cisco Traffic Analyzer must not be used with the PAA in MNM mode. The PAA in MNM mode
generates traffic with perpetually changing host addresses; the Cisco Traffic Analyzer stores this
redundant information and eventually runs out of memory.

The modes of operation are as follows:
• No truncate mode (NTM)
• Ethernet truncate mode (ETM)
• Shallow truncate mode (STM)
• Deep truncate mode (DTM)
• Management mode (MNM)
