Nexus 2148T FEX and IF-MIB


if I snmpwalk Nexus 5000 running System version: 4.1(3)N1(1a) like

snmpwalk -v 2c -c <community> <ipaddr> ifTable

I see all ifIndex, for Channels, 10G Ports und also FEX Ports. Further I see ifDescr, ifType, ifMTU etc. (all statical variables) for all these ifIndex, but I miss ifInOctets, ifInNUcastPkts, ifInDiscards etc. (all dynamical counters) for all the FEX ports (ports an 2148T itself).

Funnily I also miss the FEX interfaces in output of

sh inter snmp-ifindex

I lookes in config guides and command references and found no hint about this, but I found in datasheet of 2148T a simple entry under SNMP MIBS: IF-MIB without remark.

Any ideas?
