Cisco :: LMS 3.2.1 Sending More Pings Than Thought Usual?
Aug 9, 2011
I'm looking for troubleshooting LMS 3.2.1 and the ping/ICMP traffic it transmits.A lot of my devices are receiving a lot more pings from LMS than I would have anticipated.I don't run PING sweeps in Device Discovery or CM-UT. I've even disabled DFM polling in a hope to trace the source of these PINGs. Any list of which modules use PINGs so I can turn them off and track down the offender.I really only want to manage the known devices I already have via SNMP alone. I don't require LMS to be PINGing for discovery or reachability purposes.
I wonder if is posible to have (again) the usual redirect after log in. On DIR-635, DIR-855 after log in you get redirect to the STATUS if WAN connection si functional, else you get SETUP. Now, on DIR-825 even if WAN is active/functional the redirect is to SETUP page.
Any way to access the usual command line interface instead of using the GUI or Telnet/SSH interfaces on the Cisco Small Business SFE2010P switch? Note that the console port is not working at the moment...
I have a Dell laptop running Windows 7. The problem is that every single time I try to connect to any wireless network, I get a message that says "Connecting to the network is taking longer than usual."The network almost always connects eventually (about 2 minutes), and once connected there doesn't seem to be any other problem.This has been going on for about 2.5 months. It began shortly after I restored the laptop to factory default.
I have a WRT160N that I used just once after purchase (my ISP gave me a wireless router). I could not remember the PW, so I reset. (The computer saw the old router name but I had no PW)When I run the software (CD that came with the product says 150N), it get to "configuring computer" and stops there.I tried downloading the software, but when I try to run it says "Application requested runtime to terminate in an usual way."When I go to the 192. URl and try to login using a bank user name and 'admin," it jsut keep bringing up the password box.
So we've setup an ASA 5510 and users can VPN in no problem, and an IPCONFIG /ALL confirms that the DNS server settings from the group policy have been applied.Group policy sets DNS servers as 192.168.2.8 (internal), 188.8.131.52 (google). Public internet sites work ok.Typing nslookup opens up on the correct internet DNS server, but all requests timeout.
I have two cisco asa firewalls connected through a VPN, one is 5505 and the other is a 5510. From the 5505 I can ping the internal interface of the 5510, but not vice versa. Would that be a NAT issue? I used the ASDM to configure the VPN tunnels with the wizard for IPsec site to site.
I have recently installed a new Cisco SG 300-10 switch--running in layer 3 mode--to function as a basic router for a new subnet installed at one of my company sites. When we attempt to ping devices on the 184.108.40.206 subnet from the 220.127.116.11 subnet, each device gives 2 responses and then times out continuously after that. If we wait long enough (thus far, an undetermined period of time) and reattempt to ping the same devices, the same thing occurs. Otherwise, we get nothing but timeouts. This occurs regardless of where we connect in the 18.104.22.168 subnet including VLAN1 on the SG 300-10. However, if we connect into VLAN 2 on the switch and assign a static IP, those same devices respond continuously. I was thinking that this must be a security setting of some kind but I'm unable to locate anything in the SG 300-10 that would appear to cause this.
I'm trying to set up an 802.1 q trunk between my layer 3 switch and ASA5520. I understand I need to create a subinterface to accomplish this and have done so. However, the subinterface does not respond to pings, and when I attempt to run the packet tracer on the firewall itself, I get a message saying Flow is denied by configured rule. But the strange thing is it shows the output interface as "np identity ifc":
(The VLAN in question is VLAN2 192.168.2.3 is the VLAN2 address on the switch). The ASA config is as follows: ASA Version 8.2(5) <context> hostname context2 names ! interface GigabitEthernet0/0.2 nameif Inside0/0.2 [Code] ....
I'm having an issue that I can't quite understand. I set up a test lab to get familiar with EIGRP routing. I have a Cisco 3845-MB with 2 VWIC2-2MFT-T1/E1 cards.sh ip int brief shows UP UP status on all serial ports. I gave it an IP address but I'm having trouble pinging the serial interface IP. It's dropping pings to its own S 1/1/0 interface when pinging from console. I have known good T1 crossover cables 1&2 - 4&5.
Here is the "ip int brief" from 3845-MB
3845-MB#sh ip int brief Interface IP-Address OK? Method Status Prot ocol GigabitEthernet0/0 unassigned YES NVRAM administratively down down GigabitEthernet0/1 172.30.2.1 YES NVRAM up up Serial1/1/0:0 10.3.29.2 YES manual up up
Right now it's pinging itself at about 60 -90% success rate... and I can't figure out why it's dropping any packets at all. I have other issues with in the lab as well... but i think this might be my "core" issue.To make matters even more "weird" I've tried two different VWIC2-2MFT-T1/E1 cards and I drop pings with both of them.
Here is a sh run and a sh diag:
3845-MB#sh run Building configuration... Current configuration : 1434 bytes ! version 12.4 service timestamps debug datetime msec
Now there is an issue that I don't really know how to deal with it and its the multiplayer games ping that I get lately , its about 3 months that I get very high pings when connecting online to a multiplayer server , no matter which game it is , the same happens.
I was getting around 380-470 ping while playing on an European server , but then we solved my last problem (The someone that was connected to my home network) and it reduced the ping to something around 250-300 (sometimes it drops to 100-120).
It is still very high , 3 months ago I had a real bad internet connection and when I was playing on European server's I was getting a stable ping of 100-120 that was normal !
A friend of mine got the same connection that I have and he gets a ping of 100-120 and we play on the same servers (same ISP too).
How can I know where the problems come from ? I did move to a new house in a new area , maybe the ISP server's over there are weak and over loaded ? Because when its like 02.00 AM I am getting a stable ping of 100-120 . What is going on here ? Is there a possibility to ask the ISP to move my connection to another area servers or something like that ?
I've just purchased WRVS4400N VPN router and installed it. This was a replacement of a old Linksys router. After installing the router, I've started seeing wireless drops, packet drops and latency on pings. I've installed the latest firmware, disabled Firewall services, disabled IPS. No changes at all. As a basic example, I am pinging my NAS device (hard wired to router) from a laptop connected to wireless below. Previously while connected to my old linksys router the time was equal to no more than 2ms.
So because of the way active directory handles Group Policy I have been tasked with finding out why this is failing over the WAN. Basically I know why, but don't know how to correct it. I am trying to increase the MTU over an ipsec tunnel to 2048 to allow Microsoft Slowlink detection to occur. [URL] Basically, it sends 2 icmp packets. One at a normal size and one at a size of 2048. In my case this is trying to occur over an ipsec tunnel and failing due to the MTU being at 1440. I have seen a few articles about increasing it to 1500, but is there a way to increase the MTU to allow the 2048 sized icmp packets?
I have a WRVS4400N router in a remote office. I have connectivity to the office and computers there. But the web interface for the router is failing to come up. This happens once every few days or so. Is there any utility or something that I can use to remotely reset the router without making use of the webinterface or having physical access to the router?
After hours of trial and error, and searching user groups, I have found that on occasion, ASA v8.4 will stop pings with the IPsec-Spoofing logic. Interestingly, the packet-trace will say everything is allowed.
The fix (at least in my case, and one other) is to narrow the crypto-map to specific hosts, not subnets.
I have a d-link dslg604t, i tried to do the frimware upgrade and it froze in the process. Now the internet doesn't work at all. I have uninstalled the drivers, reset the modem and it indicates the modem is working as in i have the two monitors and the blue flashing light between them shown, also all the network settings are there. DHCP is assigned automatically etc etc. I can ping the modem but when i try to connect to the internet i get "detecting proxy server", "internet explorer cannot display the page".

Using a WRT310N Linksys Router and just today at 2PM I received the largest and longest lag spike ever, it is still going on as I write this (10:00PM). I am receiving pings of 500+ ping and my download speed spikes like crazy. Here are my speedtest.net results.Here are my results from Netalyzr URL
One Day the internet is fine the next day The Internet Stopped working. The problem is my pc is sending packets but not receiving any i though it was a bug or something so i restarted my pc after i restarted my pc the internet was working fine until a couple of minutes passed it stopped receiving packets again.i tried resetting the modem but nothing worked.I tried winsock fix or resetting TCP/IP and stuff but nothing workscause its starting to frustrate me.
Our computer is sending but not receiving packets. We've tried 3 different wi-fi adapters, and that wasn't the problem. We have no idea what's wrong? It won't pick up any wireless signals by the way, and it works fine while connected via Ethernet.
I have the following problem, right now we have an ASA 5550 connected to the client´s side. A reset is being received on the client´s side, but when we run the sniffers on both extremes of the network, we can see that the reset is not being sent by the server´s side.
We have narrowed it down to the 5550 ASA, but have found no bug that matches the description.
The characateristics of the reset packet are the following:
- It is the only packet with a TTL of 255.
- Both server and client have very different window sizes, and the reset packet even though has the server´s ip and port as source of the packet, it has the client´s window size.
- It has a correct ack number.
-Before the reset is received, there are a couple of retransmissions of the last packet sent.
- We´re handling a VPN tunnel between both servers.
We have a ASA 5520 which is configured to send log files to an ftp server. It has been doing that until recently I found out that it stopped sending the logs on August 11. I can't remember what I have changed in the ASA config to make the ftp stop. I changed the ftp config to another server but it won't upload any log file.
What can I do to make the ASA save the log buffer to the ftp server again?
