Cisco etherchannel question
by william(at)elan.net 21 Oct '04

21 Oct '04

Hi, I have etherchannel setup between cisco 7500 router and 5500 switch. For data going from 7500 router everything seems to be ok and data is well split between four interfaces with about 1/4th sent to each one (about 40% utilization each right now). But for data going from 5500 switch the split appears to be that one interface has 100% utilization while another one is 20% and others are less then 10%. So its not really splitting data on random basis to each interface and uses other interfaces as overflow after the main one. I don't like this as the one interface that is 100% full appears to sometimes be dropping packets on either switch or cisco router side. I'm wondering what I can do to force 5500 to use etherchannel in similar way cisco 7500 does? -- William Leibzon Elan Networks william(a)elan.net

by Pete Templin 20 Oct '04

20 Oct '04

Verio apparently had a power failure at their Houston TX POP, and has had routing problems ever since. Anyone have any better scoop on this? We're only receiving ~500 routes from them at this point. pt

Hmm, so let me figure this one out... Are you arguing against BCP38 implementation/filtering, or what? - ferg -- JP Velders <jpv(a)veldersjes.net> wrote: In most cases it will go like that, the minority of when it doesn't go like that, you start filtering / whatever, just like we do now.
