Explanation for Interrupt Counter Names (sh logg onboard) - FCP_MAC_...

[mwendler]

Hi there,

I´m currently looking for addtl. explanations / information regarding the "show logging onboard module" command which provides an output like this:

------------------------------------------------------------------------------

Can anyone provide me some more information what each line is trying to say me and what might be a possible reason / cause for this?

Thanks,

These interupts are for fc lower layer, does not necessary mean there is an error.

[emcprateek_2]

As explained by Galen, these are FC primitive sequences which are exchanged when link comes up or goes down. Here is more information.

Primitive Sequence - NOS

Not Operational Sequence

Transmitted by the Port to indicate that  Link Failure had been detected

Loss of Sync

Loss of signal

Port is Offline

Primitive Sequence - OLS

Offline Sequence

Transmitted by Port to indicate that it is: Initiating the Link Initialization Protocol

Receiving NOS

Entering the Offline State

Primitive Sequence  LR

Link Reset Sequence

Transmitted by Port to Indicate that it is:  Initiating the Link Reset Protocol

To Recover from a Link Timeout

Primitive Sequence  LRR

Link Reset Response Sequence

Transmitted by Port to indicate that: Link Reset is being received

Thanks for this !
