Error received on Cisco 6509 - Port ASIC (VISHAKHA) packet buffer failure

Hi Guys,

I have received the following error on one of our Core switches.

%PM_SCP-2-LCP_FW_ERR_INFORM: module 1 is experiencing the following error: Port ASIC (VISHAKHA) packet buffer failure detected on ports  45

%PM-4-ERR_DISABLE: packet-buffer error detected on Gi1/45, putting Gi1/45 in err-disable state

The port Gi1/45 is connected to a server and now it is in err-diabled mode.

I have tried to shut and unshut the port but received the following errors -

%CONST_DIAG-3-HM_PORT_TEST_FAIL: Module 1 TestNonDisruptiveLoopback Port(s)[45] failed. System operation continues.

%HA_EM-6-LOG: Mandatory.go_nondislp.tcl: GOLD EEM TCL policy for TestNonDisruptiveLoopback

%PM-4-ERR_DISABLE: diagnostics error detected on Gi1/45, putting Gi1/45 in err-disable state

I have checked the port and could not find any errors or drops -

No it is HW issue, though transient. Parity causes meory lockup on ASIC. On new cards this issue is fixed in manufacturing.

DDTS is only for informational purposes, there is no code fix.

Hi,

This could be a result of a single parity (data corruption) in the SRAM on the ASIC, which is described in

    CSCsw43503    WS-X6148A-GE-TX One port will go err-disable due to VISHAKHA error

It is recommended to reseat the card and i most cases the error won't reoccur after that.

Ivan Shirshin

Hi Ivan.

Thank you for the reply.

So is it a bug on the line card?

Thanks,

Hi Ivan,

Sorry for the late reply.

I will let you know if the restart of the line card has fixed the issue.

Appreciate your help.

Thanks
