1319.0. "Negotiated TRT 99840 ?" by VNASWS::KOISSER () Mon Apr 18 1994 07:00

    Hi there !
    
    When i read out a DEFMA (V2.0) with:
     
    $ANA/SYS
    SDA>SHO LAN/Full 
    
    or DECBridges 620 (V1.3F) and CHIPCOM FDDI-HUB's 5017 via SNMP
    
    I get the value of "Negotiated TRT" = 99840
    
    
    But I meassured the TTRT with the Wandel&Goltermann DA30 Analyser
    and the value for NegTRT was = 7.9872 ms (which is DEC default)  
    
    99840(?)/79872ms = 1.25  --> are this Controller Ticks ?
                                 or a 4B/5B encoding/decoding Problem?
                                 or just a Bug in the Display?
    
                                 Thanks for any help
    
                                                   Heinz K./Austria

	That's correct. The MIB reports timers such as T_Neg in units of 80 ns. That's what the standard requires. Blame them... paul
