CRC errors at PIX interface

HI ,

I have a PIX 535 connected through OFC to Cisco 2960 Switch.

PIX end - G0 (SC type Connector) - Switch End - Gi1/0/28 (LC type connector)

When I am pinging from either side, I am getting packet drops. CRC error is increasing at PIX interface.

Speed settings, tried with

auto - auto

auto - nonegotiate

nonegotiate - auto

nonegotiate - nonegotiate

But no improvements.

When its connected with SC - SC connector, its working fine.

Switch also working fine when connected LC - LC.

Switch OS is 15.x version.

Cisco PIX Security Appliance Software Version 7.0(4) <system>

Device Manager Version 5.0(4) Cisco PIX Security Appliance Software Version 7.0(4) <system>
Device Manager Version 5.0(4)

What could be the problem, and is there any work around available?

Hi Lenin,

If you haven't already, I would recommend swapping the cables and SFPs with known good ones to rule out any issues there. Auto/auto speed and duplex settings are usually the best way to go if you control both sides of the connection.
