Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.0(4)
OL-21012-02
Caveats
Symptom: IP DNS name resolution might be slow. For example, AAA or TACACS+ authentication
might time out when the AAA or TACACS+ servers are configured by name. This symptom might
be seen when the IP DNS name servers are functioning properly.
Workaround: This issue is resolved.
• CSCth71977
Symptom: LDAP remote authentication will fail if you configure a user with multiple roles and one
of the roles is invalid. In such a scenario, AAA skips the invalid role and applies the identifiable
roles, but SNMP applies the default network-operator role upon encountering an invalid role.
Workaround: This issue is resolved.
• CSCti06878
Symptom: An MDS 9222i switch failed with following reason:
switch# show system reset-reason
----- reset reason for Supervisor-module 1 (from Supervisor in slot 1) ---
1) At 436178 usecs after Thu Jul 15 09:39:32 2010
Reason: Reset triggered due to HA policy of Reset
Service: Service "bootvar"
Version: 3.3(4a)
Workaround: This issue is resolved.
• CSCti11858
Symptom: The port group monitor feature does not generate alarms when the configured port ASIC
bandwidth threshold is crossed, even when traffic is running that has crossed the threshold. This
symptom might be seen on an MDS 9000 Family switch running NX-OS Release 4.2(a) software.
Workaround: This issue is resolved.
• CSCti23777
Symptom: A port on a Generation 3 module is disabled and set to hardware failure state. This
symptom can occur when a port MAC has a double bit ECC error (type 87). The output of the show
logging onboard exceptionlog command is as follows:
Error Description: IP_FCMAC_ERR Interrupt, port = x, src_bit = 87
Workaround: This issue is resolved.
• CSCti33087
Symptom: Under normal operating conditions, a Cisco MDS 9500 Series switch with Call Home
configured might fail, which will cause a supervisor switchover
The following command sequence can cause the failure:
destination-profile new_profile
destination-profile new_profile alert-group License
destination-profile new_profile alert-group Syslog-group-port
destination-profile new_profile message-level 5
Workaround: This issue is resolved.
