Prerequisites
• Connect a Linux or Solaris PC to the port that will generate the Ethernet trace packets.
• Use a packet capture tool to capture the Ethernet trace packets the switch generates.
(This is optional).
Procedure steps
1. In any ACLI mode, configure the outgoing port on which the Ethernet trace packets

need to be transmitted using the command:

trace ethernet enable
packet capture tool is configured to capture the Ethernet trace packets and the
packet capture is started.
(OR)
If packets are going to be decoded real time, then ensure that the following
command is executed in the Linux or Solaris PC in superuser mode:
• In Linux, ./eth-trace-linux [-q -s 0 –n] –i <PC ethernet port
(eg: eth0)> [cpu <base|mezz> ether dst <mac address to be
filtered/decoded>]
• In Solaris, ./eth-trace-solaris [-q -s 0 –n] –i <PC ethernet
port (eg: eth0)> [cpu <base|mezz> ether dst <mac address
to be filtered/decoded>]
Where, cpu <base|mezz> is an option that specifies whether or not the test switch
is running with a mezz card. Use this to calculate the switch timestamp for each
trace packet.
When Ethernet trace packets are received, the output is displayed on the screen.
You can also redirect the output to a file.
Note:
If the cpu <base|mezz> option is not specified, the switch timestamp will not
be calculated and displayed for each trace message.
