5144.3IFDEV.C error message after protection cleanupODIXIE::RREEVESTue Jan 28 1997 14:1316
    After checking all the protections and eliminating them as a problem
    I still cannot get SNMP to answer a request . The log file 
    UCX$OS_MIBS.LOG contains the error message:
    
    ucx$os_mibs.exe WARNING IFDEV.C;1 line 253: Unexpected error in iosb, 
    reading interface IFREQ data (QIO). 
    
    I've talked to several specialist from the CSC about this error and the 
    best they can come up with is that this is due to having two IP 
    addresses assigned to the same LAN card. One address is 128.227.61.101
    and the other is 128.27.61.102. I have tried getting SNMP information
    from both addresses and receive the same error message. 
    Other IP services seem to work fine to both addresses Telnet FTP and
    SMTP should this inhibit SNMP from working correctly ?
    
    Any thoughts ?

    Hi,
    
    I dialed in and had a look at this. We got it working [briefly] by
    turning on IP forwarding and then killing the existing esnmp process. 
    
    Here's what the interfaces and routing look like:
    
    Interface   IP_Addr         Network mask          Receive          Send    MTU
    
     WE0        128.227.61.102  255.255.255.0          989309        570562   1500
     WEA0       128.227.61.101  255.255.255.0           54230        117094   1500
     LO0        127.0.0.1       255.0.0.0                  50           434  65535
    
                                 DYNAMIC database
    
    Type           Destination                           Gateway
    
    AH    127.0.0.1                             127.0.0.1
    AN    0.0.0.0                               128.227.61.1
    AN    128.227.61.0                          128.227.61.101
    AN    128.227.61.0                          128.227.61.102
    
    We found that if we stop the ucx$esnmp process and send a request
    it works once, maybe twice, then the ucx$os_mibs process goes way
    with:
    
    $ type UCX$OS_MIBS.LOG;13
    ucx$os_mibs.exe WARNING IFDEV.C;1 line 253: Unexpected error in iosb,
    reading interface IFREQ data (QIO).
    
    Ray was doing the query of .102 when this occured.
    
    Is this a valid interface configuration?
    
    Ray (onsite) will try this with only one interface and let
    us know the results.
    
    Thanks,
    
    Jim

Looks fine to me.

5144.6I think this is okODIXIE::RREEVESSat Feb 15 1997 14:262
    I think we support to IP addresses on the same physical interface .
    Everything else seems to work fine (Telnet,ftp, SMTP) .
5144.7Was there more?UCXAXP::GRADYSquash that bug! (tm)Mon Feb 17 1997 09:466
    I suspect there's more error message than that.  Specifically, it
    should show exactly what the  unexpected IOSB error code was....which
    might help understanding why it failed...
