Changing perpacket load balancing behavior

torker123
Level 1
Level 1

I have 2 Point-to-Point T-1's with OSPF, and Perpacket load sharing. When I do a large file copy over the circuits I cant get it to use the full circuit anylonger, unless I do 3-4 large coppies. It used to max both circuits just fine with one copy and now I cant get above 123/255. No config changes were made, just noticed a slowdown.

Any idea?

hi

just do post the config of ur both end router interfaces and do post the whole o/p of your T1 interfaces when doing file sharing by issuing show interface serial .

i hope u r cheking out the rx tx load which appears in percentile of 255.

do also chek the 5 min input and output,try to reduce the load interval to 30 then chek which can help u out to get the load stats..
