Add an snmp view or I should say RBAC on Nexus for the specific OID that includes the interface
So in this case look at ifAdminStatus or ifOperStatus for the e1/1 or e1/2
A snmpwalk of ifTable will give you something like:
ifDescr.2 = Ethernet 1/1
ifDescr.3 = Ethernet 1/2
Then you would add it allowing/disallowing polling of the OID ifAdminStatus.2 or ifOperStatus.2 and so on
