Hi, The router is running IOS ver 12.2(1). I guess a good first step would be to upgrade this. The dot1q subinterfaces don't show up at all in the cfg file, even as commented out.
From snmpwalk, the dot1q subinterfaces appear as so: IF-MIB::ifDescr.9 = STRING: FastEthernet2/0 SNMPv2-SMI::mib-2.13.3.1.1.2.11 = STRING: "FastEthernet2/0" SNMPv2-SMI::mib-2.13.3.1.1.2.22 = STRING: "FastEthernet2/0.2" SNMPv2-SMI::mib-2.13.3.1.1.2.23 = STRING: "FastEthernet2/0.3" SNMPv2-SMI::mib-2.13.3.1.1.2.24 = STRING: "FastEthernet2/0.955" The ISL subinterfaces appear as so: IF-MIB::ifDescr.10 = STRING: FastEthernet3/0 IF-MIB::ifDescr.13 = STRING: FastEthernet3/0.229 IF-MIB::ifDescr.14 = STRING: FastEthernet3/0.249 IF-MIB::ifDescr.15 = STRING: FastEthernet3/0.255 IF-MIB::ifDescr.16 = STRING: FastEthernet3/0.258 IF-MIB::ifDescr.17 = STRING: FastEthernet3/0.282 IF-MIB::ifDescr.18 = STRING: FastEthernet3/0.288 SNMPv2-SMI::mib-2.13.3.1.1.2.12 = STRING: "FastEthernet3/0" SNMPv2-SMI::mib-2.13.3.1.1.2.25 = STRING: "FastEthernet3/0.229" SNMPv2-SMI::mib-2.13.3.1.1.2.26 = STRING: "FastEthernet3/0.249" SNMPv2-SMI::mib-2.13.3.1.1.2.27 = STRING: "FastEthernet3/0.255" SNMPv2-SMI::mib-2.13.3.1.1.2.28 = STRING: "FastEthernet3/0.258" SNMPv2-SMI::mib-2.13.3.1.1.2.29 = STRING: "FastEthernet3/0.282" SNMPv2-SMI::mib-2.13.3.1.1.2.30 = STRING: "FastEthernet3/0.288" SNMPv2-SMI::enterprises.9.9.41.1.2.3.1.5.10 = STRING: "Interface FastEthernet3/0, changed state to up" Regards, Tawanda McDonald, Dan wrote: > On Tue, 2009-04-14 at 06:37 +0200, Tawanda Kavayi wrote: > >> Hi, >> >> I am configuring mrtg to monitor interfaces on a Cisco 3640 router.
