3.1.1 SMT Version 6.2
Some of the SMT version 6.2 MIB variables (snmpFddiSMT 2) have had
their access types extended from Read-Only to Read-Write. These
variables can be written to, using a Network Management Station (NMS).
The variables with extended access include:
•
snmpFddiSMTStationId – The port’s unique eight byte SMT station
identifier (corresponds to ANSI
fddiSMT 11). Setting the lower six
bytes to zero will cause the unit to automatically use the port’s MAC
address in the lower six bytes.
•
snmpFddiMACTMax – The MAC’s value for T_Max (corresponds to ANSI
fddiMAC 53). Possible values range from 32 to 2,097,120.
•
snmpFddiMACTvxValue – The MAC’s value for Tvx (corresponds to
ANSI
fddiMAC 54). Possible values range from 255 to 65,025.
•
snmpFddiMACFrameCts – The MAC’s Frame_Ct (corresponds to ANSI
fddiMAC 71). Any attempt to write this parameter will cause the MAC’s
Frame_Ct, Error_Ct, and Lost_Ct to be zeroed.
•
snmpFddiMACErrorCts – The MAC’s Error_ Ct (corresponds to ANSI
fddiMAC 81). Any attempt to write this parameter will cause the MAC’s
Frame_Ct, Error_Ct, and Lost_Ct to be zeroed.
•
snmpFddiMACFrameErrorThreshold – Value for the
fddiMACFrameErrorThreshold variable (corresponds to ANSI fddiMAC
95
).
Variables in the SMC enterprise MIB can be set to specify under what
conditions traps should be sent to an NMS. (Refer to the ATX MIB
Reference Guide for more detailed information.) Those variables include:
• sfddiSmtConditions – SMT conditions which should be reported to
the NMS via SNMP traps.
• sfddiSrfConditions – SRF conditions which should be reported for
the NMS via SNMP traps.
In the SMC enterprise MIB, you can set a variable to connect to port B:
•
sfddiThruB – Whether to connect to the FDDI port B (not applicable
for single-attached stations).
