The nexus 5000 supports "Unified Ports" which can be changed to act as ethernet(ethX/YY) or Fibre Channel (fcX/YY). Entries in the ifTable will identify the physical port's current mode: e.g. for FC: IF-MIB::ifIndex.16777216 = INTEGER: 16777216 IF-MIB::ifDescr.16777216 = STRING: fc1/1 IF-MIB::ifType.16777216 = INTEGER: fibreChannel(56) IF-MIB::ifMtu.16777216 = INTEGER: 2112 IF-MIB::ifSpeed.16777216 = Gauge32: 3705032704 IF-MIB::ifPhysAddress.16777216 = STRING: 20:1:23:45:67:89:a:bc e.g. for Eth: IF-MIB::ifIndex.437264384 = INTEGER: 437264384 IF-MIB::ifDescr.437264384 = STRING: Ethernet3/3 IF-MIB::ifType.437264384 = INTEGER: ethernetCsmacd(6) IF-MIB::ifMtu.437264384 = INTEGER: 1500 IF-MIB::ifSpeed.437264384 = Gauge32: 4294967295 IF-MIB::ifPhysAddress.437264384 = STRING: 0:2a:6:7:8:9a e.g. for ethernet port channel: IF-MIB::ifIndex.369098799 = INTEGER: 369098799 IF-MIB::ifDescr.369098799 = STRING: port-channel48 IF-MIB::ifType.369098799 = INTEGER: propVirtual(53) IF-MIB::ifMtu.369098799 = INTEGER: 1500 IF-MIB::ifSpeed.369098799 = Gauge32: 4294967295 IF-MIB::ifPhysAddress.369098799 = STRING: 0:2a:6:78:9:ab e.g. for FC(SAN) port channel: IF-MIB::ifIndex.67108874 = INTEGER: 67108874 IF-MIB::ifDescr.67108874 = STRING: san-port-channel 11 IF-MIB::ifType.67108874 = INTEGER: fibreChannel(56) IF-MIB::ifMtu.67108874 = INTEGER: 2112 IF-MIB::ifSpeed.67108874 = Gauge32: 4294967295 IF-MIB::ifPhysAddress.67108874 = STRING: 24:b:0:12:3:45:6:0 Notice: ifPhysAddress varies from 8-byte for WWN/FC and 6-byte for MAC/Eth - already accounted for in layer-2 parsing code ifType varies from INTEGER: ethernetCsmacd(6) to INTEGER: fibreChannel(56) (also some others like INTEGER: propVirtual(53) for eth port channels, INTEGER: propVirtual(53) for VLAN virtual IPs |
