Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(1)

OL-25090-01

  Caveats

CSCth80324

Symptom

: FCIP links flap due to maximum TCP retransmissions (“TCP conn. closed - retransmit 

failure”), or to extended pings to a peer FCIP switch that shows packet loss. This issue is due to a 
buffer leak that is caused when ICMP unreachables are generated in response to frames with an 
unreachable source address, such as 0.0.0.0.

This issue can be seen on all Ethernet ports on the MSM-18/4 module and the MDS 9222i switch, 
when either is running Cisco NX-OS Release 4.2(1) or later, or Cisco NX-OS Release 5.0(1) or later.

Workaround

: This issue is resolved.

CSCti73204

Symptom

: The 

show interface ethernet flowcontrol

 command entered on an MDS 9000 Family 

switch returned the message: “Internal error.”

Workaround

: This issue is resolved.

CSCtj92295

Symptom

: An MDS 9000 Family switch fails in the wwnmanager process. Use the s

how logging 

log

 command and the 

show cores

 command to confirm the issue:

switch# 2010 Nov  8 06:38:28 sw-dc3-br1-51 %SYSMGR-2-SERVICE_CRASHED: Service

"wwn" (PID 2897) hasn't caught signal 6 (core will be saved).

8       1         wwn              2897      2010-11-08 06:38:33

Workaround

: This issue is resolved.

CSCtk47039

Symptom

: An MDS 9000 Family switch does not respond to an FDISC from an NPV attached 

switch if the MDS 9000 switch is already processing an FDISC for the same PWWN. This issue 
occurs when the downstream device is running in NPV mode and the FDISC for the same PWWN 
must be in progress and no ABTS is sent to cancel the in-progress FDISC.

Workaround

: This issue is resolved.

CSCtl86272

Symptom

: Following a software upgrade on a MDS 9222i switch, traffic failures occurred between 

a newly configured flow, such as a regular zone flow, an FC-redirect flow, and an IVR flow. The 
ACL TCAM entry for the affected flow has no adjacency pointer and therefore no forwarding 
information for the flow, as can be seen by entering the following commands:

switch# 

attach mod x

switch# 

show process acltcam fwd-engine 0 input interface fcy/z
