Use Table 15 to determine the status of a particular caveat. In the table, “O” indicates an open caveat and “R” indicates a resolved caveat. Table 15 Open Caveats and Resolved Caveats Reference NX-OS Software Release (Open or Resolved) NX-OS Software Release (Open or Resolved) 5.0(1a) 5.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m Symptom: An IOA flow can take a few seconds to become active in certain events such as host or target port flaps. PLOGIs from the hosts are buffered until the IOA flow becomes active. Once the IOA flow becomes active, a RSCN is sent, which forces the host to perform a PLOGI again.
Caveats Se n d d o c u m e n t a t i o n c o m m e n t s t o m d s f e e d b a ck - d o c @ c i s c o . c o m 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.
