Cisco Routers :: RV110W Excessive Syslog Messages?
Mar 6, 2012
I bought a RV110W wireless router a couple months ago that I've been pretty happy with.
However, I have one significant problem with it. It is configured to send syslog messages to an internal server. Twice now it has gone into a mode where it starts dumping messages like,
ip_conntrack_is_ipc_allowed: ipc_entry_is_full
continuously, at a rate of about 20 per second. It otherwise seems to function normally, but of course if unnoticed my syslog file quickly grows to hundreds or thousands of megabytes. A reboot restores normal operation. It is running firmware 1.1.0.9. A search on the internet turned up no information about this problem.
It may be some corruption is occuring in the router's OS, or perhaps this is something that can be triggered externally (in which case it would be a weak form of DoS attack? Or maybe worse if in this state it is unable to properly apply the firewall rules.)

I have a new install of LMS 4.2 on a virtual appliance. No syslog messages are getting into LMS. They are being received by the server, but are showing up in /var/adm/CSCOpx/log/dmgtd.log, and aren't getting processed by SyslogAnalyser.

LMS 4.1 is not showing any valid syslog messages, only invalid messages. Is there anything different in 4.1 that needs to be set?

I have a newly installed LMS 4.1 that had the Syslog feature working for a while.
Recently, the Syslog is no longer displaying any records (neither new or old messages).
Below are the steps I have tried to troubleshoot the problem:
- Installed wireshark : Syslog messages are being received by the LMS server on time
- In the Syslog.log file, I can see that all the Syslog messages are being logged properly
- I tried to disable all the "Syslog Message Filters" but nothing changed
In the SyslogCollector.log, I can find the below logs:
NMSROOT is C:/PROGRA~2/CSCOpx
propFileC:/PROGRA~2/CSCOpxMDC omcatwebapps
meWEB-INFclassesC:PROGRA~2CSCOpxMDC omcatwebapps

I have a small problem with a lot of invalid syslog messages in LMS 3.2. Something about 30% of all messages are invalid.
Is there any posibility to get out from which devices those messages are?
Is it a big problem for the application if there are such a lot of invalid messages? I have a lot of devices in my LMS and don't want to get high load because of such unneeded messages.

Is there a way to debug syslog messages? Something like "debug ip syslog"?

Is there a way to get more messages out of a 2950 set to syslog? I've turned every logging option I can find to DEBUG, but all I get in my syslog are LinkUp/Down messages and "Configured from console by console". I'd love to see more information such as configuration changes, or even someone attempting to set up DTP on a switchport set to access mode.

We started getting the below syslog messages from one of our ASA5520 which was recently upgraded to 8.4(2). Any bugs on 8.4(2) that cause this or its simply the RAM failure?
%ASA-3-105010: (Primary) Failover message block alloc failed
%ASA-3-321007: System is low on free memory blocks of size 1550 (0 CNT out of 18709 MAX)

I'm building the use case to test / detect for rogue devices on the network. I have in my enviroment Lan controller 5500 controller with AP (aironet 3500). I want to detect for rogue devices/ap connected to my network. I know before i can see this activity on the network i have to configure the controller / ap to detect this behavior. I'm doing this step.
Authorize AP's against AAA function to make sure that all the AP's registering to your WLC are authorized AP's of the network.By enabling this feature, only those AP's whose mac-addresses are present in the authorization list, will be able to register to the URL
Using Rogue detection. feature, the WLC will be able to detect any AP that is not a part of its RF group and contain it.URL
NOTE: from the forum I have seen other talks about the same issue and saying that if I have any APs in "Rogue Detection" mode sitting on the trunk port on the switch then only, this AP will detect the Rogue on Wired
I don't think i completely understand this statement, by sitting does it mean that it is passively sniffing coming in/out on trunk link?
Considering the above steps are accurate, after this will i be able to see rogue detection behavior in syslogs? What exactly would be the messages that would produce this behavior.

I am using Solawinds syslog and trying to get our Cisco routers send syslogs to our syslog server. I followed the procedure on Configuring Cisco Devices to Use a Syslog Server from [URL] Our Cisco swtches are all sending syslog messages but not the routers. I compared the config with our access switches but can't seem to find the problem:
Sample router config:
service nagleno service padservice tcp-keepalives-inservice tcp-keepalives-outservice timestamps debug datetime msec localtime show-timezoneservice timestamps log datetime msec localtime show-timezoneservice password-encryption!hostname WWF-RT1boot-start-markerboot-end-marker!security authentication failure rate 10 logsecurity passwords min-length 8logging buffered 4096logging rate-limit all 10logging console critical!aaa new-model!!
[Code] .......
is there a command that prevents the router from sending the syslog to the server?

Add the ability to send syslog events to multiple syslog servers in the SA500 Series routers. I know the functionality is currently in the RV220W because we utilized it. It would be great if you could configure the syslog servers by event type as well. For example, being able to send the kernel events to syslog server A, and all other events to syslog server B.

let me know whether you can make the attached network using by RV110W or not.When I read the mannual of "rv110w_admin.pdf", P38, I guess RV110W cannot be built both NAT & Router mode.Because, I cannot setup NAT for internet access if I setup "Operating Mode" as "Router" on the setting of "Networking > Routing".And, I cannot setup the routing for internet access & MPLS-VPN access if I setup "Operating Mode" as "Gateway" on the setting of "Networking > Routing".

Is it possible to set up an RV110W to limit access to only specified websites according to a schedule? I can block access to specific sites using the Internet Access Policy settings under Firewall, but I can't figure out a successful way to block access to all sites except those specified. I also tried establishing access rules but that did not work either.

After nothing but hassles with my Linksys WAG120N, I bought a Cisco RV110W. Yesterday, I tried setting it up with the Linksys being used only as a modem. I was unable to though because when I entered 192.168.1.1 into my browser as per the Cisco setup instructions, I was taken to the admin login for the Linksys. This seemed odd to me, because the Linksys was not connected to the PC at all. The connection setup was exactly as specified in the RV110W instructions: modem connected to dsl line, ethernet cable from modem (Linksys WAG120N) to the slot marked "WAN" on the RV110W, another ethernet cable from RV110W to my PC. Despite this, the admin page was for the linksys not the cisco.
Today, I exchanged the WAG120N for a Netgear DM111P, just a modem, not a router. Same setup configuration: modem connected to dsl line, ethernet cable from modem (NetgearDM111P) to the slot marked "WAN" on the RV110W, another ethernet cable from RV110W to my PC. Same result - type in 192.168.1.1 and get taken to the admin page for "Netgear DM111P" .

I'm having problems setting up VLANs on my RV110W Small Business Router. I have updated the firmware to the latest : 1.1.0.9 Here is my set up :
WAN settings :
IP : 192.168.1.252 / 255.255.255.0 - Gateway 192.168.1.254
VLAN1 (default) :
IP : 192.168.2.254 / 255.255.255.0
VLAN3 (test) :
IP : 192.168.16.254 / 255.255.255.0
Inter-VLAN routing option is checked.
Symptoms :
- The communication from VLAN1 to WAN is fine
- The communication from VLAN3 to VLAN1 is fine
- The communication from VLAN1 to VLAN3 is not working
My routing table is :Routing table Entry ListDestination LAN IPSubnet MaskGatewayInterface192.168.2.0255.255.255.0192.168.2.254LAN192.168.1.0255.255.255.0192.168.1.252WAN192.168.16.0255.255.255.00.0.0.0LAN0.0.0.00.0.0.0192.168.1.254WAN
As you can see, the gateway for VLAN3 is set to 0.0.0.0, which is wrong I believe. I don't know how to update that. I tried to add a a static route for the subnet, but the router did not let me do that.

I am trying to configure wake on lan for my desktop and I can't seem to get it. I have tried using single port forwarding under the firewall settings but it never works. The computer's BIOS has been configured to wake on lan and so have the Ethernet ports. I have an app for the iPad that i used to use ot send out a ping to my old router (E2500) setup that used to wake the computer just fine. But this new router (RV110w) does not work at all even with the same single port forwarding set up.

I've to setup RV110W router as a simple Wifi hotspot in a company network and this Wifi hotspot has to allow traffic to all internal LAN (very simple LAN with few workstation and one server) and also to Internet via our gateway. I know this product isn't really designed for that... but I've to do so. LAN is managed by Windows DHCP server and I've Internet acces through Firewall. I think I've to connect RV110W to the company LAN with the RV110W WAN interface. I want the Wifi IP address to be in the same IP range than the LAN to allow Wifi clients to access our internal server but RV110W doesn't accept this. Or do I've to ignore the WAN interface and deal with only the RV110W LAN interface?

I have a pptp server on my network and am trying to configure my new RV110W so that I can tunnel through to it from outside.
I believe I must do port forwarding for TCP on port 1723 to get those packets going to my PPTP server. PPTP also uses GRE and I don't see that as an option anyware in port forwarding... Does that just work... as a matter of the VPN pass through checkbox being enabled ?
My netgear router would lock up every few days but it under the firewall configuration it had list of services that included PPTP and I just selected that, entered the IP addresses on the outside that I would accept, and the IP address on the inside that the PPTP clients would connect to, and it worked....
I'm thinking it is harder on this device because this device supports actually logging into it.. I am interested in learning more about that technique especially if it is more secure but the way I see it the firewall device can see all of my network and the pptp server I am using is on a file server and limited to those files shared on that server.

With firmware 1.2.0.9 - can the RV110W be used as a VPN endpoint? The VPN capabilities have been expanded in this version - but from the docs this isn't quite clear to me.

I just bought and setup a RV110W. I noticed while scanning it from the WAN side that it always has port 443 open, even when remote management and VPN access are disabled. Why is this port still open, and how do I close it? Or is this a bug in the firmware? I am using firmware version 1.1.0.9, which is the most up-to-date for this unit. Having open ports allowing unsolicited contact from the WAN side, especially inadvertant ones, is a major security hole.

I have recently hit a brick wall with my router... Yesterday the router was acting funny rebooting about every 5 to 10 minutes. Didnt really think anything of it then it got annoying fast. So i checked my configs and nothing was out of normal checked my firmware and noticed it was out of date. So i grabbed the newest firmware 1.2.0.9 and uploaded it... uploaded fine and then rebooted as it should at that time the power flickered again because somone had plugged an large ac adapter over top of the power switch on the power bar and it was intermittently turning the power off when the table moved... the router then power cycled mid update and is now stuck at the blinking power light state and hasnt changed for 24 hours now...

I am thinking about buying one of the 2 routers i have listed above. I have some concerns though.
First off what are the MAJOR differences between the two? (they look the same to me)
Do they both contain PPTP and is it simple to configure? Do i need any kind of special client software? Can i use my iphone and ipad to connect to the vpn server. Is there a minium download/upload speed to have a vpn sever?

Regarding to the connection RV110W to any Cisco router, should I use a crossover cable accordingly? Because, I heard that the crossover function is done inside of some switches and routers. So, I would like to know whthether the function is included into RV110W.
