I have a cisco router 2951 and this is the message that apear on the console:
ERROR: DDR controller 1 data training time out during initialization! Stop.
What does it mean?
We are a medium-large sized company with approx.100 offices located across North America. Every single office connects to each other and the data center via a DMVPN overlay network. The DMVPN hub router (Cisco 2951), R-Q9-1, is located at our data center and is the "workhorse" of the company. We also have a redundant hub router, R-Q9-2, at the data center with exact same hardware specs.
Each office builds an EIGRP Tunnel0 and Tunnel1 to R-Q9-1 and R-Q9-2 respectively. All data traffic flows over Tunnel0 to R-Q9-1 until it fails, at which point traffic starts to flow over Tunnel1 to R-Q9-2. This has been working seamlessly for last 1 year of implementing this design, until yesterday, when both R-Q9-1 and R-Q9-2 rebooted all of a sudden at the same time right in the middle of a production day. I confirmed there was no power failure at the data center. A show version of both routers gives me this:
R-Q9-1 uptime is 1 day, 1 hour, 24 minutes
System returned to ROM by address error at PC 0x5C92E28, address 0x5DF36FE9 at 11:52:23 EDT Tue Sep 21 2010
System image file is "flash0:c2951-universalk9-mz.SPA.150-1.M3.bin"
Last reload type: Normal Reload
[code]...
I Google that error but can't find anything specific other than it's saying it's some kind of bus error. What I also found a bit off is the time it's showing on both routers' show version output (Sep 21, 2010 and Jan 10, 2012). Here are the current clock settings on both routers at the time of this writing.
R-Q9-1#sh clock *16:53:31.216 EDT Wed Oct 31 2012
R-Q9-2#sh clock *16:59:44.220 EDT Wed Oct 31 2012
I checked my Syslog server and did not find anything specific during the time of the crash, however, syslog was filled with errors similar to this one
2469: * Tunnel0: NHRP Encap Error for Resolution Request , Reason: protocol generic error (7) on (Tunnel: 10.10.200.1 NBMA: IP address ommitted)

I have never seen these errors before and all of a sudden they seem to have stopped since this morning.
Looking for some training on the 2500 series controller and 1142 or 1040 AP's preferably.
View 10 Replies View RelatedHow to get a WLC on a SRE up and running. I have a WLC installed and running on a 2951 SRE connected to a L3 switch in a lab.
I've tried to follow the Cisco document:
[URL]...
My wireless clients could only receive a DHCP allocated IP address for the 55.XX subnets defined on the wireless lan controller and SRE (shown on page 12 of the pdf). All traffic seemed to be routed via the native vlan of the inside router trunk interface and all DHCP requests arriving at my DHCP server were from 55.XX. Because of this I didn't see the point of trunking
so I've changed it to a point to point routed connection, created a 55.XX DHCP scope on my DHCP server for the wireless clients and all routing works fine.I found the document rather misleading.
Cisco 2951 w/ HWIC-4ESW

#sh ip flow int
Vlan533
ip flow ingress
ip flow egress

The SVI sends the flow data just fine, however I also continue to receive flow data from most other interfaces.
I have attached a screenshot of one of our netflow collectors indicating that many of the interfaces are sending flow data even though not configured to do so. We have two different netflow collectors, from different vendors and both confirm the same interfaces sending flow data.
Normally I wouldn't care and ignore it, however one of them uses a license limit by interface and is a bit problematic.

I have 5 public, static IP's provided by my ISP. I read on another page that to use the 2nd, 3rd, 4th and 5th IPs, I must first 'register' them by entering them on the WAN page and I must wait until I can successfully PING them from an external network. Then I can set the WAN IP back to the one I want to use to administer the router. Then I can use those other IP's on the various Access Rules or Port Forwarding pages where there is a spot to enter 'alternate WAN IP address'. I'm trying to determine if this is true because I'm having a heck of a time getting port forwarding to work. My BIOS is 1.0.3.5.

View 2 Replies View RelatedI have just bought an E3000 router when my old router died last week. I am having two problems:
1. The data rate slows down after a period of time (long message trail elsewhere)
2. I cannot see everything on the network.
I have several Win 7 computers, two win xp computers, three NAS devices (linux based), and a printer sitting on the network, along with two switches to cope with all the traffic (not to mention iPods, iphones etc.)With my old router, I couold see everything plugged into the network from my main Win 7 computer. (note: the win 7 network map does not always work, but the windows explorer window of the network always showed everything).With the E3000 router, I can only see 1 or 2 of the devices on the network. If I reboot the router, then sometimes all of the devices appear on the windows explorer window (sometimes not)I am running a workgroup (not a domain) and i am not using win 7's homegroup because that will not work with the non-win 7 devices.Is there a setting that will see all of the devices in Win 7 (either on the router or on the computers). I suspect it is a router issue as it worked with my old Zyxel router.

I'm starting to see an error creep up that I havn't seen since 2003/2004 on my brand new 5508 controllers. I'm recieving the following from my WCS: Receive Multicast Queue is full on Controller and then on the controller itself RX Multicast Queue Full. I understand this used to be due to a large influx of ARP requests or CDP packets on older controllers but, this was supposed to be fixed in an update many years ago.
Has seen this on their 5508's. These were advertised as having the horsepower to handle our user loads which arn't really that high at 300 users at any given time max.
so i can not connect to net on my desktop but my wifi works fine, the error is the realtek PCIe FE family controller (code 31) i have tried updating the drivers but nothing i have verizion fios.
