Time base rate-limit

I have T1 link that is always over utilized. We have implemented a rate-limit on the interface. We want to limit the traffic for Lotus notes during business hours then let it use all the bandwidth after office hours.

Here is my config

interface Serial8/1/3

rate-limit output access-group 187 256000 96000 192000 conform-action transmit exceed-action drop

access-list 187 permit tcp any 10.95.0.0 0.0.255.255 eq 1352 time-range limit-lono

time-range limit-lono

periodic weekdays 12:00 to 22:00

The rate-limit should work between 12:00 PM to 10:00 PM From Monday to Friday and the rate-limit will not take effect from 10:01 PM every night. I will be active again the next morning 12:00PM. Then it will be inactive from 10:01 PM Friday night till 11:59 AM on MOnday morning.

When I do show access-list 187 after 10:00PM

sh access-list 187

Extended IP access list 187

10 permit tcp any 10.95.0.0 0.0.255.255 eq 1352 time-range limit-lono (inactive) (59299139 matches)

I can see the ACL is inactive but the matches are still increasing, does this mean the rate-limit is still working?

During the so called inactive period of the rate-limit, When I remove the rate-limit config in the interface, the Lotus notes admin told us that he is receiving the Lotus notes traffic as per normal but when I put back the rate-limit config, he still receive the Lotus notes traffic but in the slower pace and it takes time. Does this mean my rate-limit is still working even though the time I set is inactive?

Appreciate any input you can give. Thanks in advance.

Re: Time base rate-limit

Hii..frm ur reqmt i understand d following is needed:

limit traf for ln durin bus hours: 12.00 PM to 10.00 PM (M - F)

unlimit traf for ln after hours : 10.01 PM to 11.59 AM (M - F) &

10.01 PM to 11.59 AM (F - M)

now as per my knowing the config needs changes as u hv not included the deny time:

permit tcp any 10.95.0.0 0.0.255.255 eq 1352 time-range limit-lono

deny tcp any 10.95.0.0 0.0.255.255 eq 1352 time-range unlimit-lono

time-range limit-lono

periodic weekdays 12.00 to 22.00

time-range unlimit-lono

periodic daily 22.01 to 11.59

try these and let us know the results.

pls rate the post.

Re: Time base rate-limit

Hi,

Thank you for the response.

I have modified the periodic daily as the one above is not accepted

periodic daily 22:01 to 11:59

Ending time must be greater than starting time

time-range unlimit-lono

periodic daily 22:01 to 23:59

periodic daily 0:00 to 11:59

I config this to the router and I will observe on the specified time. I will let you know the result.

Thank you very much

Don
