Can you please distinguish between 3w1d: %LINK-3-UPDOWN: / 3w2d: %LINK-3-UPDOWN:

Hi while I am checking logs on my cisco switch, (Show logs), I can see
#show logging (out put modified)
3w1d: %LINK-3-UPDOWN: Interface FastEthernet1/0/15, changed state to down
3w2d: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet1/0/15, changed state to down
3w4d: %LINK-3-UPDOWN: Interface FastEthernet1/0/15, changed state to up

Can you please distinguish between 3w1d / 3w2d / 3w4d,
is it possible to find at what time the interface flapped by seeing 3w1d / 3w2d / 3w4d?
I forgot to change the time stamps in my switch to date time.(it was "service timestamps log uptime" )
Thanks in Advance

Hi thanks for your reply, can you please explain me in detail - is it possible to find the exact tme it flapped?
my apologies if my mistake, it seems 3w1d for 3 week 1 day and the most recent 3w4d means 3 week 4 day? is that increasing ?  is that status  counts from the last reload?

It's since power on or last reload.

I don't know if you can get an exact time.
Your system has never had the timestamp attached to syslog messages, do that now to avoid time discrepencies in the future.

config t
service timestamps debug datetime msec
service timestamps log datetime msec

Your messages will now have the appropriate timestamps, make sure you synch your time with a timer server
