This symptom might occur when a PortChannel is created over Gigabit Ethernet ports.

Symptom: The following exceptions are logged in the module exception log of Cisco MDS 9000
Generation 4 modules:
1. TBIRD_FWD_IAF_ACL_PIORD_LSB_ECC_ERR
2. TBIRD_FWD_IAF_ACL_BANK0_LSB_ECC_ERR
3. TBIRD_FWD_IAF_ACL_BANK1_LSB_ECC_ERR
4. TBIRD_FWD_IAF_FIB_PIORD_LSB_ECC_ERR
5. TBIRD_FWD_IAF_FIB_BANK0_LSB_ECC_ERR
6. TBIRD_FWD_IAF_FIB_BANK1_LSB_ECC_ERR
7. TBIRD_FWD_ETI_SPANS_PIORD_LSB_ECC_ERR
8. TBIRD_FWD_ETI_SPANS_BANK0_LSB_ECC_ERR
9. TBIRD_FWD_ETI_SPANS_BANK1_LSB_ECC_ERR
The count of relevant errors per module (from the last time counters were cleared) can be seen by
the following command:
switch# show hardware internal errors all | inc "LSB_ECC| in module"
If TACACS accounting is enabled, the following messages will be in the syslog:
%TACACS-3-TACACS_ERROR_MESSAGE: All servers failed to respond
%AAA-1-AAA_SESSION_LIMIT_REJECT: aaa request rejected as maximum aaa sessions are in
progress
This symptom occurs only on the Cisco MDS 9000 32-port 8-Gbps Advanced Fibre Channel
Switching Module (DS-X9232-256K9) and the Cisco MDS 9000 48-port 8-Gbps Advanced Fibre
Channel Switching Module (DS-X9248-256K9).
The main cause of the issue is the exceptions generated on the module. These exceptions do not
impact operations. However, the unthrottled notification exceptions are not desirable, and might
cause switch resources to be overwhelmed. These notifications should be disabled until it is possible
to upgrade to software where this issue is fixed.
Workaround: This issue is resolved.

Symptom: An HDS AMS Truecopy path failure occurs in a topology with an HDS AMS initiator
and target, and a Cisco MDS 9509 switch with a MSM-18/4 module and a Cisco MDS 9222i switch.
IVR NAT is enabled with both devices in an IVR zone. The path between the initiator and target is
active after the IVR zone set is enabled, but after the FCIP link goes down and then up, the Truecopy
path stays offline unless a manual recovery is initiated. This problem does not occur without IVR.
Workaround: This issue is resolved.
