clearing cef stats on an interace [7:55555]
Any body know how to clear cef stats on an interface? I need to be able to clear the counters showed by the command sho int serial4/2 stats We've got an interface that seems to be process switching 80% of it's traffic and we're trying to nail down why.

Looking for experiences with 7500 and POSIP [7:54486]
We are adding an OC3 to our network due to a recent contract w/ a large web hosting company. We are looking at using the POSIP card. The contract requires that they have the ability to saturate the OC3 w/o dropping any packets. I am worried that my 7500 w/ a vip2-40 will start dropping packets under heavy load, there are 3 other DS3 interfaces on the router that are at about 60% utilization. Has anyone here had any experience w/ this combination that can give me some pointers. I'm trying to not have to buy this card just to move to a 12000 in a month because it's dropping packets.

Re: blocking spam with cisco routers [7:48971]
I wouldn't even think of using a router for this purpose unless you are only using smtp mail between your own sites and don't want outside email f/ anywhere. We run spamassasin (www.spamassasin.org) on our mail server and it cuts out 80-90% of our SPAM.

2 T1's to our provider [7:49039]
We are upgrading to 2 T1's to our provider, Fractional DS3 is prohibitively expensive in our rural area. Has anyone done any speed comparisons on using round robin style static routes (i.e. 2 default routes w/ same cost) versus EIGRP's load balanceing versus running MLPPP on the Serial interfaces? We're currently using a 2621 but are open to "bigger" routers.

Re: IGRP & OSPF mask issue [7:46187]
I assume you mean eigrp not igrp, if you are using igrp, remember it's classfull and takes the default mask, eigrp is classless... you'll probably need to do some summarization also... if I see the configs I can fix it in 2 seconds... - Original Message - From: "Sunil Rawoorkar" To: Sent: Monday, June 10, 2002 4:42 AM Subject: IGRP & OSPF mask issue [7:46187] > Hi , > > Is anyone there to help me out on mask issue betwn OPSF and IGRP.
