Out EMC Smarts cannot draw the link between Nexus 7000 and the connected servers on the screen. EMC engeer said the problem is caused if the agent does not report the MAC address of the neighbor node. Then I snmpwalked for the Nexus 7000 and confirmed that it actually didn't send dot1dTpFdbAddress.
Is this a bug or limitation of NxOS?
CCO document says NxOS supports Bridge-MIB though.
Thanks in advance.
