Configuring Cisco 6xxx switches using a SPAN port to a full-duplex Gigabit Probe
When using a full-duplex Gigabit Probe to capture directly from a SPAN/mirror port, use a straight-through cable from the Gigabit port on the switch to either port A or B on the Gigabit card in the probe. Do not use the Y-cable or TAP (the TAP and Y-cable should only be used inline).
To use Observer with the Cisco 6xxx switch, you must disable auto negotiation. With auto negotiation enabled, the switch and probe may create a link when first starting the probe, but if the cable is unplugged or if a configuration change to the SPAN/mirror port is applied, you will lose connectivity to the switch. To turn auto negotiation off on the switch, follow the directions based on the OS you are using on your switch.
Tip! Disabling Auto Negotiation is recommended on all models/brands of switches when using a SPAN/mirror port to a full-duplex Gigabit Probe.
