Hello,

 on somes devices, i have a problem with blank space in my networking graph, i have this problem only with somes devices, others devices (same hardware and OS) work well. Please find attached examples.

 The devices are Cisco N3K-C3048TP-1GE running on NX-OS 6.0(2)U3(7) (uk9).

 On working device (with normal graph) all ports are 64bits, on devices with blank problem all ports are 32bits.

 When i poll a device with the blank problem, i have:

o CISCO-VLAN-IFTABLE-RELATIONSHIP-MIB  cviRoutedVlanIfIndex
 o SMON-MIB
 o CISCO-TRUSTSEC-INTERFACE-MIB
 o ADSL-LINE-MIB
 o EtherLike-MIB        dot3StatsDuplexStatus
 o Q-BRIDGE-MIB
 o IP-MIB               IP-MIB ipIfStats


Negative ifOutOctets. Possible spike on next poll!

 On working device, i don't have this negative values and the "HC" column has "Y" value, not "N".

 Do you have an idea about the problem?

Thank! Regards.
