  • Cisco Nexus 3000 Series Switches

Known Affected Releases

6.0(2)U4(0.41)

Description (partial)

Symptom:
After some time of normal operation, Nexus Data Broker (NDB) is suddenly no longer reachable
through the GUI.

Openflow switches using the underlying XNC as controller report a connection failure to the
controller. For example:

2014 Nov  9 05:06:22 switch01 %VMAN-5-VIRT_INST_NOTICE: VIRTUAL SERVICE 
ofa_ndbemb LOG: OVS: sw1<->tcp:10.0.0.1:6653%management: no response to 
inactivity probe after 5 seconds, disconnecting

2014 Nov  9 05:06:22 switch01 %VMAN-5-VIRT_INST_NOTICE: VIRTUAL SERVICE 
ofa_ndbemb LOG: OVS: sw1<->tcp:10.0.0.1:6653%management: connection failed 
(Connection reset by peer)

Conditions:
This has been observed on NDB 2.0 running embedded on a Nexus 3548 running NXOS 6.0(2)A4(1)
It is not confirmed at this time whether or not other versions or other platforms are affected.
