ASIC chip failing in Cat3750?

[mj5150]

Hi,

I've just noticed an error I've never seen before in our switch logs.  We have a stack of 6 Cat3750G-48TS-E switches.  The first two in the stack have been up for just over a year and I've only just noticed this error.  Thus far, I haven't noticed any symptoms - I just stumbled upon this error while checking for something else.

As far as I can tell, this has only popped up once and it was 2 days ago.  Unfortunately, thanks to an incorrect firewall rule, our syslogs were not getting to our syslog server so I don't have any historical logs to check against, but it hasn't happened since.

The error I've seen is as follows:-

Jun  5 17:04:03.288: * ManagementInterfaceInitialized exception in port-asic 0 (N16FujitsuSwitch.com.au-2)

Jun  5 17:04:03.288: *********************************************************** (N16FujitsuSwitch.com.au-2)

Jun  5 17:04:03.288: * ManagementInterfaceInitialized exception in port-asic 1 (N16FujitsuSwitch.com.au-2)

Jun  5 17:04:03.288: *********************************************************** (N16FujitsuSwitch.com.au-2)

Jun  5 17:04:03.288: * ManagementInterfaceInitialized exception in port-asic 2 (N16FujitsuSwitch.com.au-2)

Jun  5 17:04:03.288: *********************************************************** (N16FujitsuSwitch.com.au-2)

etc. Up to port-asic 7.  All errors are showing N16FujitsuSwitch.com.au-2 (ie the 2nd switch in the stack).

Otherwise, everything seems to be functioning normally.  In searching for this, the only thing I saw was another user who had this problem (coincidentally only a week ago) who contacted Cisco TAC and was told the ASIC chip was failing.  He had symptoms whereby normal switch traffic seemed to be functioning fine but he was losing IP connectivity to the switch.  The difference here is that he appeared to have a single switch - no stack, and in my stack, switch 1 is the current master.  I am having no connectivity issues to the stack.

I'm obviously thinking that the safe thing to do is to replace this switch in the stack.  Has anyone seen or heard of this issue?

Mark Johnson

ManagementInterfaceInitialized exception in port-asi

Never seen this before.

I'd get this unit RMA-ed.

Problem: Hardware failure.

Solution: Read above.

ASIC stands for Application-Specific Integrated Circuit. On a switch, there are many ASICs - you can have an ASIC dedicated for NetFlow, ACLs, among other services.

The more ASICs you have in a switch, the less you use the CPU for those services hence making the switch a lot faster.

In the 6500/4500, the ports are group due to the oversubscription nature and they are physically connected to an ASIC. This hardware controls traffic to/from the port or group of ports.
