All I have gotten from Cogent is a canned response: --- The latency and/or packet loss that you are experiencing to this destination is due to occasional high traffic with Verizon. We have repeatedly requested augments to these congestion points and hope Verizon will comply soon. While this has been escalated internally to the CEO level, we encourage you to also contact Verizon customer support with your concerns and complaints. Their delay is a major impediment to internet traffic overall and contrary to net neutrality requirements. Our peering engineers will continue to address this on a daily basis until resolved. --- It seems to have gotten a lot worse in recent days, to the point where we have customers who are trying to access us from Verizon's network (i.e. they have Verizon DSL, or via Verizon 3G/4GLTE) complaining they are having a very hard to checking their email, etc. Has anyone else been experiencing these issues? Or does anyone have more information that what Cogent provided me in their canned statement? -Bobby

05 Feb '14

Hi there, I have a Cisco 7606 with this module on it: WS-SUP32-GE-3B and I am using its own 8 port like this: 2 Port Layer two ether-channel uplink to my 4900 Cisco Switch and 1 Layer two uplink to Internet, and near 10 tunnel to my customers for internet exchange with BGP peering + some policy map for shaping tunnel interfaces. My ether-channel traffic on 600Mbps (each port 300Mbps) I get 90% cpu load and ping time problem on my router, what is the problem?? And when I run: show processs cpu sorted I get a "Unknown" process eat the cpu process... I try lots of IOS version but it does not make difference. My IOS version is: c7600s3223-adventerprisek9-mz.150-1.S1.bin and some general configuration: no ip source-route > ! > ip cef load-sharing algorithm original > no ip domain lookup > ! > ! > ! > ! > mls ip cef load-sharing full > no mls flow ip > no mls flow ipv6 > mls qos > mls cef error action reset > multilink bundle-name authenticated > ! > spanning-tree mode pvst > spanning-tree extend system-id > system flowcontrol bus auto > diagnostic bootup level minimal > port-channel load-balance src-ip > username admin secret 5 $1$g6WX$LaQbPyD3qIaHsF5qTqt8g0 > ! > redundancy > main-cpu > auto-sync running-config > mode sso > ! > ! > ! > ! > vlan internal allocation policy ascending > vlan access-log ratelimit 2000 Thanks -- Regards, Shahab Vahabzadeh, Network Engineer and System Administrator Cell Phone: +1 (415) 871 0742 PGP Key Fingerprint = 8E34 B335 D702 0CA7 5A81 C2EE 76A2 46C2 5367 BF90
