Hi all,
int the last 3 weeks,
almost every day , we have a series of events in the connection between one Nexus 5596 and one of our servers. The connection is in FC (4G).
I need help to understand the output of the following command to troubleshoot what could be happening.
Sw-cpd-mm-n5k-2# show hardware internal fc-mac 3 port 14 link-event
MMDDYY HHMMSS usecs Event Current State
------------ ------------------------------------- --------------------------------- ------------------------------
- - LINK_ACTIVE
100113 020845 773895 (0001) E_LINK_IDLE LINK_LRR_RX
100113 020845 765016 (0000) E_LINK_LRR LINK_LR_TX
100113 020845 763545 (61CB28) E_LINK_LINK_RESET LINK_ACTIVE
Sw-cpd-mm-n5k-2# show hardware internal fc-mac 3 port 14 port-event
MMDDYY HHMMSS usecs Event Current State
------------- ----------------------------- ------------------------------------ -------------------------
- - IPS_LINK_UP
100113 020845 775908 (0000) E_IPS_LINK_INIT_SUC IPS_LINK_UP
100113 020845 775907 (0000) E_IPS_IDLE IPS_LINK_UP
100113 020845 770040 (0001) E_IPS_LRR IPS_LINK_UP
100113 020845 763562 (61CB28) E_IPS_CREDIT_LOSS IPS_LINK_UP
Looking at the output I don't know who generates "E_LINK_LINK_RESET" , Nexus switch or server?
Thanks in advance!

Hi,
I know it is a little bit late, but hope it can still be of use...
According to the log output, The switch detects a Credit Loss condition
00113 020845 763562 (61CB28) E_IPS_CREDIT_LOSS IPS_LINK_UP
and to recover from it, the switch resets the link by sending a LR to the server
100113 020845 763545 (61CB28) E_LINK_LINK_RESET LINK_ACTIVE
the server replies with a LRR, IDLE, etc.
100113 020845 765016 (0000) E_LINK_LRR LINK_LR_TX
