Troubleshooting protocol errors
You can use Flow Mirror to mirror protocol error frames. The following example mirrors only ABTS
frames egressing through port 1/20 to identify the ABTS protocol condition.
NOTE
This example can also be set up to mirror frames based on the total ABTS count provided by Flow
Monitor.
1. Right-click a target port (1/20) and select Fabric Vision > Flow > Add.
The Add Flow Definition dialog box displays with the following criteria and flow identifiers
pre-populated:
•
Feature — Monitor
•
Direction — Bidirectional
•
Source Device — Source identifier
•
Destination Device — * (an asterisk allows you to use any port)
•
Egress port — port number (1/20)
