A alternative way it to update the SNMP uptime timestamp is to do a call like
|
||||||
|
snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but call to
|
||||||
|
a lower frequency). Another one is to not call snmp_inc_sysuptime() or
|
||||||
|
snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
|
||||||
|
This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
|
||||||
|
snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
|
||||||
|
when it's queried (any direct call to "sysuptime" is changed by a call to
|
||||||
|
snmp_get_sysuptime).
