Workaround: Bring up multiple links between two switches one at a time. Verify that the first link
came up correctly before attempting to bring up the next link. If the first link fails to come up
because of a domain ID overlap, resolve the domain conflict and then try again to bring up the links.

Symptom: FCIP links may fail on an MDS 9216i switch that has compression set to auto when the
other end of the FCIP link is terminated by an IPS-8 module. You may see the following message in
the logs:
%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 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.

2. Withdraw the troubled domains using the ivr withdraw domain domain vsan vsan-id
command.
Readvertise the withdrawn domains using the ivr refresh command.
