I am attempting to build a cfgmaker work-alike script that will dynamically build targets to monitor thruput and packet loss for FCIP (fibre-channel-over-ip) TCP connections. My FCIP infrastructure consists of several Cisco m9200 switches running NX-OS.
So far I have discovered that: 1) Querying the standard TCP-MIB objects on this platform is not useful because FCIP related TCP connections, retransmissions, and thruput stats are not included. 2) The Cisco FCIP mibs (cisco-fcip-mgmt-ext-mib.my and cisco-fcip-mgmt-mib.my) are no help as they appear to only reference configuration objects and not stats objects. 3) There are some very promising looking OIDs that appear to be an undocumented offshoot of the CISCO-TCP-MIB (cisco-tcp-mib.my) objects. Regarding item 3 above, I am able to get some interesting data when I snmpwalk the top level of the CISCO-TCP-MIB tree. However, despite properly loading the CISCO-TCP-MIB and dependent MIB files into two different MIB browsers, I am unable to resolve the OIDs to names. Even when I manually open up the cisco-tcp-mib.my file I am unable to map these OIDs to names. So from looking at the output below I'm 95% confident that the data I want (directional bytes per connection, directional packets per connection, and retransmissions per connection) is there, I just don't know what OID is what. My questions to the list is: Is anyone else using SNMP to monitor individual FCIP TCP sockets? How? Is anyone else able to map the OIDs below to names? If so, can you send me the mapping? I have been all over the Cisco (and other) on-line mib browsers navigating the CISCO-TCP-MIB tree but the OIDs that are listed through these tools do not come back with any data when I query my devices. This is the top level of CISCO-TCP-MIB, but nothing resolves to a name... snmpwalk -v2c -c public myswitch .1.3.6.1.4.1.9.9.6 SNMPv2-SMI::enterprises.9.9.6.1.2.0 = OID: IF-MIB::ifIndex
