FYI: CNS MICE Switch upgrade to 20Mbps
by Steve Howard Nov. 21, 2014

Nov. 21, 2014

Hello, We are planning to upgrade the CNS Switch connection to a 2x10Gbps LAG tomorrow morning around 5:30-6:00AM. I suspect that this will cause a brief outage for the members that are connected to the MICE switch. If this is a problem for anybody, please let me know and we will reschedule to next week. Thanks, Steve

Gigapop Link Saturated
by Nathan Beard Nov. 10, 2014

Nov. 10, 2014

All, It appears that the Gigapop link is saturated, and I've had multiple reports of packet loss on traces to IP's that traverse the exchange link. I'm sure people are already aware of the issue, but does anybody have an ETA on when another link will be added or what is currently being done? Thanks. --

CNS Remote Switch LAG Port
by Jason Hanke Nov. 7, 2014

Nov. 7, 2014

Please allocate xe-0/0/29 for a second 10G link to the CNS Remote Switch. The port will LAG with the existing 10G connection xe-0/0/38 when complete. Doug/Anthony, can you coordinate with Steve? -- Jay Hanke CTO Neutral Path Communications 3 Civic Center Plaza, Suite 204 Mankato, MN 56001 (507) 327-2398 mobile jayhanke(a)neutralpath.net www.neutralpath.net

MICE Traffic
by Anthony Anderberg Nov. 6, 2014

Nov. 6, 2014

Summary: Yesterday afternoon we had a ~20M spike in egress traffic on MICE that seems to have been caused by the main switch not populating a MAC address or two in its L2 table. Since it appears we've seen this before and none of the recent storm control features got triggered it seems like a bug that will need a little research. I don't believe traffic exchange across the network was affected. Gory Details: In late afternoon I noticed that normally quiet ports all had identical graphs showing ~20M of egress traffic. Seeing that it started at about the same time as several changes on the CNS remote switch I called Steve Howard and together we worked through the issue. Counters indicated that it was unicast traffic and Steve wasn't seeing the same patterns on his switch so we zero'ed in on the idea that it was unknown unicast packets (unicasts who's destination MAC wasn't in the L2 forwarding database.) Since that doesn't make any sense in our environment and logs didn't show continuous storm control activity we cleared the L2 forwarding table on the main switch at about 18:41 and traffic immediately returned to normal and has remained normal since. Interestingly there was one burst of logs for a couple seconds like this at the beginning: Nov 5 13:41:04 MICE-SW1 backup MRVL-L2:mrvl_fdb_mac_entry_uc_set(),966:FDb SP HW-overwrite failed(3) for VLANIdx=3:5c:5e:ab:d5:9e:f0/48:IFL=137 I did a search on the error and one of the few hits was some yahoos in Minnesota trying to setup an Internet exchange... but that'll never work. :-) https://www.google.com/search?q=juniper+%22mrvl_fdb_mac_entry_uc_set%28%29%… Other links suggest there is a Juniper bug ID and associated software upgrade so we'll need to do a little research to see what makes sense on that front.

Google IPv6

Steve Howard posted this handy URL: http://redirector.c.youtube.com/report_mapping When I visit that URL with IPv4, I'm now seeing "mice-msp1". Yay! But with IPv6, I get lvlt-bna1 (2607:f850::/32) [u]. Are others seeing Google at MICE via IPv6? -- Richard

MICE Offload rates
by Jason Hanke Oct. 31, 2014

Oct. 31, 2014

I'm looking for some stats on the percentage of traffic that MICE is handling vs transit links. I will use the average of the numbers to assist in bringing in additional members. You can unicast me if you don't want the info public.
