Cisco Switching/Routing :: 1811/k9 DDR Memory Test Failed?
Oct 25, 2012
Recently i atsrt having problems with my cisco router 1811/k9, apparently was booting continiosly when restarted.
After i connected my console i found the problem while booting:
DDR memory test failed. Resetting the router ...
I tried to contact cisco TAC, but i need a reseller contract number to place a ticket, i do not have a resller contract number as my router was bought more than two years ago. I called cisco support and they told me to contact my reseller, my reseller told me to contact cisco so i am in a eternal loop of forwarding phone calls...

My Dell Inspiron Win 7 equipped computer cannot connect to the Internet. I have a DSL router that I can wirelessly connect to, but it says no Internet access. I used the manual Intel Wireless Manual Diagnostic Tools to test my system and failed the ping test. Dialog box says "no response, default gateway,DHCP server" and indicates the ping test failed.I have checked my router and it is working nominally; other laptops in my family have Internet access just fine. My Intel Centrino Wireless N 1030 adapter is working fine. I detect no other hardware problems on my laptop.

I connects to the wireless box and has full signal but an exclamation mark is present.I have run some tests and the IPv4 and IPv6 say they have no internet access.I also run a full test and everything passed except the ping test which failed and it said: no response:default gateway response: dhcp server it suggested disabling security firewall but i'm not sure if that's the correct thing to do or even how to do that!

Ran a diagnostics test and failed the Ping test. I'm using the university resident internet. Called the tech place and they said they're investigating their connections and networking thing on their end. Just in case though, I want to know if there's actually something wrong with my laptop rather than their equipment.

Region : Italy
Model : TL-WR740N
Hardware Version : Not Clear
Firmware Version :
ISP : Alice (Telecom)
I bought some days ago Tp-Link Wireless Router (Model TL-WR740N - 150 Mbps - Ver 4.23) but I couldn't install it: when I do Easy Setup Assistant, the network status test always fails because of absence of connectivity. I can see that there are some problems by the lights of the router: the WLAN light switches on, as the WAN light and the LAN light, instead of being flashed. I tried to do the installation without cd but, clicking on 192.168.1.1, I didn't find the page to access to web console but the Telecom page of the status of my connexion (nb: it reports that ethernet is unplugged).

I got an asa5510. After problems with ipsec connections the log said :
LU allocate xlate failed this error repeats every minute. At the cisco site i found the following :
explantion : stateful failover failed to allocate a translation (xlate) slot record recommended Action : check the available memory by using the show memory command to make sure that the security appliance had free memory in the system. If no memory is available, add more memory
But when i do there is free memory. (about 54%)
What can i do to fix this ?

We have a Cisco 881 router, which is crashing. We have seen that the ARP cache fills up so much it causes things to crash, our phones go down.. We dont know why this however IP CEF seems to be doing it, when we disable it goes away however disabling IP CEF causes our L2TP tunnel to become inoperable also. So why does IP CEF cause thousands of AR entries and how can we limit that!? Below is the error, sample of the ARP cache and our config. You will notice we also have a /31 given to us on WAN interface, this was given to us by our service provider. This is really strange I cant find other examples on internet.
The error:
Nov 1 04:21:57.474: %SYS-2-MALLOCFAIL: Memory allocation of 65536 bytes failed from 0x81F083F4, alignment 16
Pool: Processor Free: 55176 Cause: Not enough free memory

I have a Cisco 1811 with a 4/port Serial Async/Sync (HWIC 4 A/S) and another 2 port A/S serial wic. My router seems to have a problem reading the 4/port card. I did some research and it looks like there shouldn't be a compatibility issue.

My question is wrt policy-based routing on my network. Our switch is a 3560G 24PS running Adv Ip Services image. It is connected to an 1841 and an 1811 each with a dual-wan connection . The 3560 defines 6 vlans and we are using PBR to route some vlans via the 1841 and some vlans via the 1811.
From a client on one vlan a traceroute to a client on another vlan goes through the 1811 before being routed back to the 3560. Is it possible to use PBR to detect traffic that is destined for another vlan on the same switch and then route it directly?

The last few days I've been exploring options in getting rid of some old routers accross a wan connections. I have a cat 3560 to play with and I thought I would try and use the no switchport command test out routing with switch. I've got some type of route issue and I tried a few things which I thought would fix the issue but had no effect. I'll post the config and a few commands so you can see what the basic setup is.
Here we can see in the arp that it knows about both 10.7.1.2 (PC unable to ping 10.3.3.254) as well as 10.3.3.254 (ASA).I tried adding in a ip route of 10.7.0.0 255.255.0.0 10.3.3.110 as well as 10.3.3.254. Neither produced the results I wanted allowing 10.7.1.2 (PC) to ping the ASA (10.3.3.254). [code]

I am currently getting a strange error when trying to use and crypto services on our ASA 5520 (8.0.3)Initially I observed that a connected VPN had dropped.Then when I attempted to use ASDM or SSH I was blocked.
In the end I opened telnet as a test and this was successful. Syslog also shows that traffic is passing as normal.The only obvious error I can see when observing various debug traces is this;
FW02# CTM: rsa session with no priority allocated @ 0xCF1FBBA0
CTM: Session 0xCF1FBBA0 uses a nlite (Nitrox Lite) as its hardware engine
CTM: rsa context allocated for session 0xCF1FBBA0
CTM: rsa session with no priority allocated @ 0xCE7A5EA8

Attached setup i am planning for testing multicast output from different vendors using VLC and STB. This Setup made to test the picture quality between the vendors at the same time on the multi viewer screen.
1) Only a 2960 Gig port switch with only one L2 v lan with IGMP snooping enabled.
In this scenario where Source and receivers are in the same L2 v lan ( no L3 interface is involved) hope i would able to test all the multicast sources with out any additional configuration on the Cisco switch.

We are trying to test multicast between VRFs configured on Nexus 7Ks. Two Nexus 7Ks are configured for VPC. Multicast Server is in one VRF where as Receiver is in another VRF. The two VRFs are connected to each other via Checkpoint Firewall (Active/Active cluster in unicast mode). All routes have been established and connectivity tested between multicast server and receiver using ICMP.Using, windows mcast.exe multicast stream is generated from server (in one VRF) intended to be received by receiver (in second VRF). Every time, only one multicast packet is received by the receiver and rest all packets are being dropped. Server and Receiver are VirtualMachines configured on VMWaresame chassis which is connected to two Nexus 5Ks (VPC configured).

ISRG2 (c2951-universalk9-mz.SPA.152-4.M1.bin) has 512 MB of DRAM. Periodically it runs out of memory: [code]
1. Why "show process mean" command shows less memory than 512 MB? Processor Pool (248 MB) + I/O Pool (58 MB) ~ 310 MB only?
2. *Init* process holds more memory than normal (202 MB). What may cause this?

have 3 Catalyst 3750 in same stack, the IOS version is 12.2(53)SE2. Today we can not telnet/ssh to this switch, but ping is ok, and switch function is ok. I try to access the console port, it show "low on memory, try again later". After I reboot the master switch in the stack, the master switch change to another switch, then I can telnet/ssh to this switch. I check the Ciscoworks server syslog report, there are many MAC address flapping error message, and I beleive the MAC address flapping occured before several weeks. ( the G2/0/15 & G3/0/15 is connect to a VMware ESX server and the EtherChannel config mismatch with this Catalyst 3750 switch ) How to mention the root cause of the "low on memory" problem and what is the abnormal memory usage ( free memory percentage below ?% )?

I have a bootflash in 4507R with the size of 60MB. I upgraded the ios from cat4500-ipbasek9-mz.122-37.SG1.bin (12.8MB Size) to cat4500-entservices-mz.122-37.SG1.bin (13.8 MB SIZE) and deleted the previous IOS.But previous IOS is still getting shown in sh bootflash: command. Furthermore, dir bootflash: commands shows there is only one IOS , which is running. How I can free the space from bootflash , as I again have to upgrade the another new IOS ( of 16MB), which I tried through solarwinds tftp and couldn't upload successfully because of its limitation. Now, If I try to upload the new IOS through FTP, it gives me memory space error. How I can free the space captured by old IOS and also how I can delete the 3rd unknown entry of IOS (shown below output of commands)?
