%IPS_SB_MGR-SLOT1-3-CRYPTO_FAILURE: Heartbeat failure in encryption engine (error
0x1)
%ETHPORT-5-IF_DOWN_SOFTWARE_FAILURE: Interface GigabitEthernet1/1 is down (Port
software failure)
%PORT-5-IF_DOWN_SOFTWARE_FAILURE: %$VSAN 1%$ Interface fcip99 is down (Port software
failure)
Workaround: If both ends of an FCIP link are not on an MPS-14/2 module, do not use mode 1 and
auto.

Symptom: A data path processor (DPP) might fail on an MDS switch running SSI Release 3.2(1)
on the SSM. The failure occurs after several days of running traffic when a misbehaving target sends
unexpected frames well after the response has already been received from the same target.
Workaround: None.

Symptom: If there is a request to export a domain while the same domain is being cleaned up,
domain entries might not be programmed. As a result, communication between IVR devices might
not occur.
Workaround: Because the the programming request was lost, the only way to retrigger the
programming is to withdraw the domain and refresh IVR. Follow these steps:
switch# show ivr internal dep
Internal information for DEP FSM
--------------------------------
vsan domain nh status sync_status req i/f
101 0x61(97) 1001 ALL_DONE OXID|FCID_RW 0 [ fc3/2 ]
102 0x62(98) 1002 ALL_DONE OXID|FCID_RW 0 [ fc3/5 ]
1001 0x9e(158) 101 NONE OXID|FCID_RW 0 [ fc2/16 ]
1002 0x98(152) 102 ALL_DONE OXID|FCID_RW 0 [ fc9/10]
Number of DEP entries : 4
After waiting for a few minutes for IVR to stabilize, if the status column for the {vsan, domain}
combination is NONE, then this problem has occurred the switch.

Symptom: In rare cases, an FCIP link might flap on a network with high latency and a consistently
high loss rate.
Workaround: None.

•
Symptom: When IVR exports a new virtual domain and multiple border switches export that virtual
domain, some of the entries in the Fibre Channel name server (FCNS) database that correspond to
this virtual domain may have partial entries where the port type contains a dash (-). This can then
lead to a lack of IVR communication between these devices and other IVR devices.
