Hi All,

The below interface on the PIX 535 is having a lot of CRC and input errors. what can be the reason ? and how to solve it? let me know if any further information is required.

Interface Ethernet1 "3PGW", is up, line protocol is up

Hardware is i82559, BW 100 Mbps

Full-Duplex(Full-duplex), 100 Mbps(100 Mbps)

Description: TO 3PGW LB

MAC address 000e.0cbc.c9fc, MTU 1500

IP address 10.160.83.1, subnet mask 255.255.255.224

Check duplex mismatch, physical connections need to be consistant, if 100 full duplex in the firewall the other end needs to be the same, check cabling as well if duplex is not the issue.

you may want to also clear the counters after you correct physical.

Problem might be related with the BW value

here is a link that could help you with the issue

Take a look to the Speed and Duplex Settings part. Good luck

it's not speed and duplex.( they are negotiated correctly as per the o/put ).

it's a bad cable on that interface.

replace it.
