[alcatel-nsp] Uptime on 7750SR12

[Garcia Del Rio, Diego (Diego)]

Indeed it sounds like you just rolled over the uptime counter. Its a 32 bit counter in 100ths of seconds (10msec). This means it rolls over at 497 days and a few hours.

It's most likely the following known limitation listed in the TiMOS release notes:

After 497 days, system up-time will wrap around due to the standard RFC 1213 MIB-II 32-
bit limit. [51129]

In other words, the 7750 probably didn't reboot.

Hi Cyril,

Since there was no service impacting and abnormality I'll explore with community first :)

Hi Jon,

I've alert with 7210 500days and already upgraded all 70 SAS-E within 6 days :D

It might be similar issue ?

Thanks

ALU sent a warning about a month ago, concerning 7210 SAS could reboot after 500 days.

maybe the same warning applies to 7750-SR?

Hi Expert,

I have check one of my 7750SR12 router got uptime 58days, but I couldnt believe that the reason due to rebooted. I've check on 5620SAM no alarm related node rebooted or hardware error.
Also since 58days back no outage was reported. Anyone knows what is the reason, or uptime reset after 500 days ?

Thanks
LP
