Cisco :: LMS 4.0 Reachability Tests For Simple IP Address?
Jun 29, 2011
is it possible with LMS 4.0 to do a simple reachability test for an IP address not based on device?The ip address I want to check for reacheability is not the management ip address I add in Inventory->Device Administration->Add->Device Properties->IP Address For example: I want to test the reachabilty of the IP-address 10.113.15.4, not management ip, it shall be an interface ip address.With the performance monitoring I want to test the reachability, if it fails continuously 2 times I want to get a notification with an low severity.After 6 continuously fails of the reachability test I want to get a notification with an medium severity and in the end after 12 continuously fails of the reachability test I want to get a notification with an criticaclc severity. The threshold configuration and the threshold criteria should not be the problem,the problem is where do/can I enter the corresponding ip address I want to test.

I have recently bought cisco 2901 in order to replace it with our 1811W that we have at the moment.When I try to set a failover / backup with rtr; it seems like the function is not valid.Once I select rtr and set the object #, the reachability command is not available.Does that mean this function is not a part from the license package I have?

I am looking for a script or applet that will dis/enable an ethernet interface on Cat 6500 based on reachablity to an external destination. Reachability should be verified either directly by sending ICMP packets, or based on IPSLA status.

I have 2 pairs of Nexus 5000 units (pair 1 and pair 2). A pair consists of 2 Nexus 5000 (A and B) connected to each other via a VPC containing 2 ports ie P1-5KA -- P1-5KB (vpc domain 6) and P2-5KA -- P2-5KB (vpc domain 10) [code] Hsrp exists between all four with a virtual address of 10.18.136.1. P1-5KA is the Active with P1-5KB as Standby.
I can ping between the four using their SVI addresses. I am unable to ping the HSRP virtual address .1 from P2-5KA or P2-5KB.I can ping ok only if I shut the VPC between P2-5KA or P2-5KB or define another mac address under the HSRP config other than the system default. IP Packet debugs show that ping sourced from P2-5KB to P1-5KA loop between P2-5KA -- P2-5KB. Pings sourced from P2-5KA to P1-5KA are transmitted but none of the 4 device debugs show a receive. both peer-gateway and delay restore 120 have been configured under all vpc domains and all units rebooted.

I don't do a lot of networking however during a cisco lesson the other day my lecturer briefly touched upon loop-back tests, would it be okay for somebody to very imply sum up exactly what loop-back tests do in a couple of lines and how they are carried out? (not in detail, so literally for example - a wire is put in from one end of the network to the other etc.) I don't really understand all the different wiring types etc.

About a week ago, our network started to experience complete failure.
Our Equipment:
Router: Netgear FVS336.xxx
Switch: Dlink DES-1024D (we have 6 of these switches in our building)
Wifi Routers: Dlink DIR-601, Linksys wrt54g, wrt54gv2
Computersservers: 40x
Copiersfax: 5x
Wireless clients: (iphones, laptops) at least 30
All has been working together in harmony for many years.Fast forward to last week when my hell began with intermittent crashes.Not sure what's causing the problem.When it happens, everybody loses their internet, the ability to communicate over the network; ping tests won't respond to anything (including the router) that exists on the lan, even with a static IP against other statics.In visually inspection of the switches and router, they seem to be happily blinking away with no apparent issue (visually).The only way I've been able to fix the problem is by power cycling the router.About 1 second after doing that, we're back in action for 2-6 hours (very unpredictable).I never had to power cycle any other devices)
Steps I've taken in troubleshootingeliminating potential culprits:
Replaced the router with a spare (new) FVS318G
Replaced the power supply for the router (suspected because problem remained after router swap)
Replaced cable going from router to lan switch
Removed linksys wifi router from network (the router had needed power cycling weekly and was old. So I unplugged it)
Removed Dlink wifi router from network (I hate dlink routers, so removed it).I'm at a loss.

I'm new to the site and for the past couple of days I've been trying to figure out why my connection is so slow. I only get about 180kbps of download speeds so I originally thought it was my internet, but I went to test my connection speed on speedtest.net and I get around 1mbps. I also checked my network utilization through task manager and I'm not even using 1% Any Ideas as to why I can't make full use of my connection?

Do I correctly understand that when two ASA 5510 are in fail over pair, the switchover from primary to secondary if one interface of primary goes down shall happen ONLY if failover link is up? So when the fail over link is down and one interface on primary got down also, interface tests between the two ASAs still are being done , but secondary SHALL NEVER try to become active.
In this case why to make tests on data interfaces ? What is the reason to make them? If the knowledge of that some interfaces of primary became down comes through failover link - no need to make additional interface tests - primary will tell about the failure to secondary. If so should run no monitor-interface if name command to dis load devices and network by foolish tests?

We're since long having a problem with a DSL internet connection. The connection goes down periodically, for short times, and when performing speed tests, the connection speed varies and is usually lower (0.7 Mbit/s) than what the ISP promises (1.5-2 Mbit/s). Moreover, what modem is being used seems to have an effect.Now, I want to trouble-shoot this and get some hard facts on the behaviour of the connection. I would like to do repeated speed tests over say 24 h or so. They should be done every 3 min or so (to catch short glitches).
My question is: what software tool can I use for this? I have been searching the internet for hours, downloading a handful of applications, without finding anything that I could use. There are loads of applications that log and graph the current upload and download speeds, but that's something else - I need a tool that downloads/uploads files from/to a server, in intervals specified by me (3 min), logging the result and presenting it graphically.

Att says they are giving us 3mb/sec but we get 300kbps and speed tests from anywhere say we get 2.5 to 2.9 mb/sec yet even on unlimited bandwidth downloads(like torrents) with thousands of seeds connected and a few peers they never get faster than 340kb/sec.

So I've noticed a big speed drop in my comcast internet. I went from routinely scoring over 20mbps on speedtest.net to around 11. Also, the upload test fails everytime. On every speed test site I've been to, the upload test completely fails. I haven't changed a thing so I have no clue why this would happen, but maybe it might have something to do with the speed decline.
I have an old WRT54G router that I've had for almost 10 years and I was thinking that maybe that was the problem. So I tried directly connecting my modem to my rig, but for whatever reason, I couldn't get it to work.
I can build unbeatable gaming rigs and program like crazy, but I just do not have networking in my skill set. It confuses the hell out of me and always seems to be completely random. What I can do to isolate and resolve my problem?
Oh, on one of the upload tests I got the following error.
"Trial measurement failed. Client can't send/receive UDP packs to server port 8601".

I need to configure ADSL on my 837 Router with simple configuration. The WAN IP address is dynamic from my ISP. I checked many websites and found different configurations everywhere. I don't know which is best suited for me. I used SDM and configured ADSL. When i checked the configuration from console i found that there is atm0.2 and dialer 2 configured with my settings. I cannot understand what is the purpose of atm0.2 and dialer 2 when atm0 and dialer0 are there. Is there a doc on ADSL config on 837?

I have a room cut off from the wired network by concrete walls (there are windows and it's a very short distance). There is a device in that room with a wired network adapter than needs access to the network. We'd like to use a pair of WAP4410N devices to get that room on our wired network over a simple "wireless bridge."
Would the following work?
Connect one WAP4410N normally with WPA2 Personal encryption and connect it to our wired network. Enable repeating of its signal.Set up the "remote" WAP4410N in the "cut off" room. Give it the same SSID and Encryption settings. Enable "Wireless Client Repeater" mode and uncheck the box labeled "Allow wireless station to associate". . . then use its RJ45 network port to connect to the wired device in the room. My biggest concern is the part in bold. Will the network port on the "remote" repeater function like that? So that any devices (or a switch) plugged into it will then be "forwarded along the bridge" to the main/local AP and then onto our network?

I've tried setting up some simple port forwarding on my ASA, where I want to forward one port on the external interface for both UDP and TCP to the same port on an internal server.
It works fine for UDP, but all TCP packets are dropped on the outside interface, even though the configuration for UDP and TCP is basically the same! This is my config:
object network MY_SERVER
host 10.10.1.4
object service TCP_MY_SERVICE
[Code].....
Port count goes up on line 2 (UDP) but never for line 1. I just see the packet denied instead. Same thing happens in the packet tracer, a packet destined for my external interface on that port for UDP is allowed and NAT'd just fine. TCP it gets dropped by the ACL on the outside interface.

I am trying to find out if its possible to use an existing CISCO 2940 Switch that we have here at our office as a hub? Im sure that borders on insane however, let me break down what we have currently and what I'd like to do.
We currently have a very nice setup here at work, with no problems whatsoever, however; we hired a new person and brought in some new printers and we are running out of wall jacks. Rather then run all new cabling and adding new outlets/faceplates etc... We were just gonna go purchase a simple Netgear 5 port switch/hub from the Local Comp store here in town. We found in our server room a what appears to fully functional and operational cisco 2940 8 Port Switch with a Gigabit port.
All IPs in the office are assigned via DHCP, so....on to the meat of my question -- I tried to plug this into our network and I can't get any connectivity out at all. All the ports light up green etc when I plug in the comps but they aren't pulling valid IPs.
I want to reset this thing and start from the ground up, I am not scared of going into the IOS and modifying what needs to be done...as long as I got a good enough walk through.

I would like to create 3 x VLANs on an SG 300-28P and have them completely isolated from each other, for example ports 1 - 12 on VLAN 1, ports 13 - 24 on VLAN 2 and ports 25 - 28 on VLAN 3. No communication between any of the VLANs.
Any simplest way to achieve this?

I would like to setup a simple VPN on a small network, nothing special, just to provide access to some simple resources on the network from anywhere. Since I'm not a Cisco expert, I was advised to user a 861 router, but I just can't seem to get the VPN working on this device.
I've placed the router behind a modem and did some basic configuration. Hosts who are connected to the modem (on the Vlan side) can access the internet and can setup a VPN connection to the router. A VPN connection from inside the network is worthless, but I just can't get the VPN working on the FastEthernet4 connection.
Any VPN config for a 861 router for this situation? Or how to configure this device as a VPN server?

I`m trying to get a simple VRF and routing setup going.The "routers" are Cisco C3750G-12S-E.What I want to do is separate the management network form all else.The public network is illustrated with private IP ranges, these are really public ranges.
I think the best way to solve this will be using VRF for management, and regular routing for public network, right? Putting the management network in it`s own VRF.

I'm new to routing and cisco in general. I'm inheriting a rather simple setup but would like to approach the next steps with a good strategy. Currently we have a 2901 router with public IP's on bother interfaces. The internal facing interface is our gateway for some webservers and a firewall. Not we are looking to add a colocation site and establish a site to site VPN using another 2901. My goal is to have the colocation use the same internal 10.100.0.0/23 network. My question is what is the best way of going about this since the router at the main site has public IP's on both interfaces? Do I need to multi-home the internal facing interface? If so, what else needs to be done?

I know the general difference between a router and a switch, but after considerable reading I'm unable to determine if I could just use a switch for my pretty simple specific application.
Here are the two devices I need to setup on my network (connections would be wired, both devices in close proximity): (1) computer running windows2k with 100mbps ethernet card (has software firewall installed) (1) blue ray player for streaming netflix videos
Because I don't have any computers on the network communicating with each other, based on what I've read it seems possible to just connect a switch to my cable modem instead of using a router.

I need to replace an ADSL modem and have a spare 857W. Can I use this to act as a simple bridge between the ADSL PPPoA connection and the FW WAN port?
[ CISCO 857W ]
ISP - PPPoA - BRIDGE - FW WAN
I have a block of Public IP's so the PPPoA Dialer 0 connection would get x.x.x.185/29 I would like to bridge this directly to the FW WAN port and set that to x.x.x.185/29 with a gateway of x.x.x.186/32.Currently I am using it in router mode with no NAT or FW and am losing a Public IP as I need to set the FW WAN as x.x.x.186 with a GW of x.x.x.185 I am setting BVI 1 as x.x.x.185/29 and Dialer0 as IP Unnumbered BVI 1.

Have a Linksys E-3000 router and a WAP-4410N which I wish to configure as a repeater to extend network coverage. E-3000 IP has been changed to 10.10.1.1. How do I do it ? What do I connect to what in order to configure the WAP-4410N to new settings? It will of course be located remotely from the router. At this time network consists of a main PC and 2 wireless laptops. I have read the manual and it doesn't answer the above described situation.

if you bring your new firmware, please verify the small bug in 'Time Settings': If you choose CET (GMT +1h) AND enable 'daylights saving time' the time goes back 6 hours instead of forward 1 hour.Firmware of RV120W: 1.0.1.3
I'm surprised that CISCO needs such a long time to solve such an issue... I thought I bought the new router from a leading network provider
