MDI: Sets the port to connect with a PC using a crossover cable (manual mode-applies only to copper port switches using twisted-pair copper Ethernet cables) Status and Counters in the menu interface. To see what the switch negotiates for the auto setting, use theCLI show interfaces brief command or the 3.
It should be set to mode 3 per Brocade.Auto-MDIX (default): Senses speed and negotiates with the port at the other end of the link for port operation (MDI-X or MDI). Correctly set the fillword on the switch for 8Gb HBAs. Sometimes there is a need to change the configuration because the default settings cannot run without errors due to the environment.ġ. Most connectivity issues are caused by bad quality of the cable/SFP, broken HBA/hardware, or incorrect configuration of the SAN switch. To set the fillword, use the portcfgfillword command. To check the fillword setting, use the portcfgshow command on the switch command console. Brocade often recommends that the fillword be set to 3 for 8 Gbs HBAs, consult the SAN switch vendor to confirm. Too many counts of er_bad_os indicate that packets were dropped from the SAN, causing latency or link failure. Too many "enc out" counts without "crc err" counts, implies primarily a cable problem, and if Lr_in and Ols_out are quite equal then problem is most likely not caused by the switch.Ī high er_bad_os count might point to an incorrect fillword setting. Ols_out -> offline reset out (primitive sequence), does not apply to FL_Portīack to the switch log. Ols_in -> Offline reset in (primitive sequence), does not apply to FL_Port
Lr_out -> Link reset Out (primitive sequence), does not apply to FL_Port
L r_in -> Link reset In (primitive sequence), does not apply to FL_Port Note: If the “Ols_in” value is higher than the “Lr_out” value, then the problem source is, in most cases, more related to the attached device (sending those offline sequences) and the switch responds to them with a link reset.Įnc out -> Encoding error outside of frames Index Port Address Media Speed State ProtoĠ 0 020000 id 4G Online FC F-Port 10:00:00:00:c9:5d:b3:ca "out") or are caused by the switch ("out" > "in"). The switch command consoles show two dedicated FC ports split to the dedicated FC switches.
This issue is caused by a connectivity problem in the SAN fabric, and can be confirmed by reviewing the SAN switch log. Backup jobs for clients to an 5220 Appliance using Fiber Transport (FT) always fail with status 83.
