Re: Speed or duplex mismatch?

by Owen DeLong

Some flavors of Cisco will drop inbound ICMP if they feel busy. When this happens, they do it silently and do not count errors, etc. I don't know if the NPE G2 is subject to this proclivity or not and I don't know how busy your router feels when you are doing this, but, the particularly regular pattern to the packet loss leads me to believe it is likely a CPU spike in the Cisco for some scheduled periodic task causing it to fail to process the inbound ICMP Echo Reply. (Remember, ICMP to the router is punted to the slow-path CPU) Owen On Oct 3, 2011, at 7:47 AM, Jeremy Lumby wrote: > This weekend I did some equipment upgrades, and while my BGP session re-established without a problem, I decided to ping the route servers to test connectivity.

Speed or duplex mismatch?

This weekend I did some equipment upgrades, and while my BGP session re-established without a problem, I decided to ping the route servers to test connectivity. I found that both route servers exhibited about a 0.5% loss. I checked my interface counters, and I am not getting any errors, as well as I tried pinging a few other MICE members' routers and did not experience any loss. I am wondering if there is a speed/duplex mismatch between the route servers and the switch, or if there might be something running on the route servers that is intentionally dropping packets as some form of DoS protection.

Connection to Sungard: Not really a MICE question...

by Steve Howard

Hello, This isn't really a MICE question, but I figure somebody on the list would know the answer and I'd prefer to send the business to a MICE member. I have a customer that is looking to get to the Sungard data center on Energy Park Drive. Does anybody know of any reasonably priced ethernet connectivity to get there from 511?

We already have IPs in place for routing providers and while it was only a /29 there should be room for another device like this. Blank out a router and ship it to MICE care of myself at ipHouse. Doug will be heading over to remove the Cisco 4500 in the near future, get the new router over before he goes there and he'll set it up and install it. -- Mike Horwath drechsau(a)iphouse.net The universe is an island, surrounded by whatever it is that surrounds universes. - Berkely Fortune ######################################################################## To unsubscribe from the MICE-DISCUSS list, click the following link: http://lists.iphouse.net/cgi-bin/wa?SUBED1=MICE-DISCUSS&A=1

Jay's voulenteer list reminded me. This past Tuesday, I posted a suggestion for a donated MICE looking glass option. Did anyone have any coments on the post? I am attaching it below if you missed it.
