Cisco :: L3MPLS Monitor Network In QOS Environment
Mar 11, 2012
i am using L3MPLS VPN services from a provider.They are doing QOS, like my Voice, Data, ICMP. all traffic is classified in their network and take different paths.Now sometime when we face voice issues, simple ICMP ping , TCP ping, will not give me insight if there are any packet losses, since Voice packets are taking someother path with in MPLS cloud due to DSCP marking of Voice pack to 46.is there any tool in which i can change DSCP value of my packets and test out network response? or any monitoring tool that can do this by default?i am looking for freeware at the moment or trial
The internet connection at our business goes down overnight, every night. We then have to turn off the router and turn it back on. It is not the fault of the ISP, but some setting somewhere, either in the router (SG 310 Snapgear) or in a particular program being accessed each night. Fact is, for the time being we are just trying to find out the precise time when this happens, so we can find out a reason. Is there a utility that can monitor the status and tell you at what exact point it stopped?
I am supporting a small call center of all Win7 machines. There is no server in house as everything is web based. Anyway, we want to find the bandwidth hogs and programs that I am used to using require servers for monitoring web traffic.
Are there any devices or software that is not a fortune that can give details on bandwidth usage?
I keep getting warning on bandwidth usage , I'm using a dir-615 routers xp on all machines . The one pc that i use to d/l with I have the torrent monitor on and shows little traffic. Ive heard of a few pieces of s/w but these require software to be installed on all boxes Id like to be able to monitor from one box if possible ??
I have a cisco catalyst 2960-s PoE switch. I have a web access to the switch and am able to get statistics on each port. However, I am wondering if there is a way to have a diagram of the trafic on each port?
Also, what is the best way to monitor the trafic on a router ( i have a cisci 1811W)
I have some questions about monitor of status of services on Network Devices such as HSRP, Etherchannel (between Access ports and Servers), etc. How we can track those information in addition to Syslog. Is it possible that the Fault Monitor displays them?
if I have a unprotected wireless router and someone start using my router, will i be able to monitor what they doing using my router internet connection?
I would like a free tool that would moniter the internet usage of our network. it has about 20 computers and would like the following features: be able to show the usage of each computer the type of usage, ie, browsing, downloading, streaming a total usage Is there such a free program? would Microsoft Network Monitor 3.4 be able to do the trick if i learnt how to use it?
we have a high speed internet and my modem is capable of wireless what I want to know, is there a way that I can monitor how much my daughter is on her computer and what websites she is visiting without having to install a program on her notebook or having to check her history etc? I would like to be able to do it all from my computer
I went to Furrynutz link where I never found the direct download lilnk to the widget. I then chatted with a Microsoft representative at the widget page and he linked me to the same Furrynutz's link.
My DIR-825 has the latest firmware, 2.06xx and works flawlessly, even the shareport usb port works without a hitch with a Seagate Expansion 3TB drive connected into it. What I simply would like is the D-Link gadget.
I have a DIR-655 router running 1.21. The last couple of years, I've always been checking the firmware version by pushing the "Check Now" button on the web management - it has always responded with "This firmware is the latest version. " I've been researching networking monitoring tools and came across this link: [URL] It requires that you update to the latest firmware - and this time I sued on the on-line link - and it turns out that the firmware version for my device is actually 1.35NA?So... first question is - why does my router tell me that 1.21 is the current version?I'd like the network widget - what are pros/cons of updating from 1.21 to 1.35NA?Have there been fixes to the scheduling portion? - 1.21 cannot handle 24-hour time properly. I also have to reset the router daily - sometimes more often - due to problems when used wirelessly. (Fortunately I try to use wired as much as I can.)
I'm wondering if there is an easy way to monitor how much bandwidth is being consumed at any given moment for a home network.specifically, for the incoming/outgoing internet connection.My network is as thus:
Most devices are connected directly into the switch, with one computer hard-plugged into the DIR-815 (I will eventually change this, as the 815 only has 10/100 ports).Basically, I want to easily be able to check how much up/down data is being sent for my internet connection. This means that I cannot use a program on a computer (I've used DL Meter before. Works great, but limited to a single computer).
The Linksys E4200v1 is using standard firmware, but I'm not opposed to loading DD-WRT onto it (was the original plan anyway, just never got around to it), if DD-WRT has this capability.Nice to have feature: Ability to see which devices are consuming what part of the bandwidth. Not necessary, but would be a cool feature.Alternatively, if there is a cheap (like $100 or less deal) box that can interface, say, between the E4200 and the switch, that can do this, that would work as well.
Have a PC set up with a LINKSYS N2500 router. this is password protected for access to network I would like to monitor what one of my children is doing on the net - but they surf the net using an iPad
Does one can use a Vacl to monitor network traffic on a nexus 3064 much like you can on the 6500s? If so, any performance tradeoffs or caveats to be aware of ?
I have 5 linux and 3 Microsoft 2008 Servers, each connected to 2 Cisco 3560 Switches. The 2 Cisco 3560 switches are connected to 2 different Cisco 515e Pix. Is it possible that if i enable Port SPAN in any of the switchport and send a copy of traffic to any of the windows 2008 server, will i be able to monitor the bandwidth of the servers (Here I am only looking for traffic going from servers to PIX and then to internet, also vice versa).
Also will wireshark be able to differentiate specify the bandwidth of each servers seperately ?
I am using WRT54G, I have 3 pcs connected to this router, some wired, some wireless.I need to monitor from my PC what my kids are doing on their PCs, including website visited, chat, email etc. Which software to use, or do I need to buy additional hardware?I have downloaded a application, however, it needs hub or switches on top of router. And my kids r connected by wireless and if I ask them to change to wired connection, they may not like it.
I want to create a network with a bunch of routers and switches to be used as a test network for company employees to remotely login and learn networking.I don't want this network to interfere with the rest of the network in any way.I am basically trying to create a stub network or a passive network!!
Currently I'm with a pure Cisco shop, running every LAN Switched infrastructure (even in the HQ datacenter) with PVST+, I'm noticing in the documentation I've read and labs I've created that RSTP is... great, and I've observed that even the uplinkfast functionality seems to be build in by just enabling rapid-pvst. Of course I'll propose a migration plan, document the network, diagram it entirely and provide effective steps to implement the change, but that's assumed from any get'go.
question 1. in the typical active directory environment and doing wireless/wired 802.1x authentication on endpoints, should ACS join as a domain computer?
question 2. for the endpoint (domain computer) join the domain, in this case is the endpoint will trust the ACS ( also domain computer) ?
question 3. what if there's a GPO policy to install the rootCA certificate toward the endpoints. In this case, ACS should issue the CSR and let the domain CA to signed as the identity certificate? Am i correct?
I am using the "File exist"-check in my Dynamic Access Policies to be sure that VPN-computers are corporate. I would like to place the file in each users %APPDATA%-directory, but it seem that the ASA cannot use variables when specifying the path? Is there a way to do this or do I have to use a absolute path in the check?I am running a ASA 5520 with sw 8.4(1).
Today, we have a server running SNA that connects to router via the following. Vitrual Server --> Nexus 1000v ---->Nexus 7010 ---->2800 series router.We are trying to move server to new environment where it is Virtual Server ----> Nexus 1000v ----- Fabric Interconnect-----Nexus 55xx-----Nexus 7010-----2800 router.
Need securing a wireless environment in a hotel? The SSID has to be broadcast of course but how can we protect guests from man in the middle attacks, etc.? Currently the environment is all AP1200s with no hardware upgrades in the near future. There is also a 2811 router in place but nothing else. We would love to be able to force users to authenticate with a password in order to get out to the Internet as well.
I was asked to mount ACESMs on each of the CAT6K switches of a VSS cluster (one ACESM on each individual switch).On a non-VSS environment, the "svclc module <slot> vlan-group <group>" command is used to bind the VLAN group to the module on a certain slot. But now I am facing a VSS scenario, I will need to combine switch and slot in order to reference each of the individual modules...
How do I "index" each of the ACESMs in a VSS cluster? ¿Is there an extension of the aforementioned command to be able to combine switch and slot information?
I am looking to slowly migrate some of our wireless devices (Aironet 1231 and 1232's) to the Wireless N spec - 1260's.I currently have four AP locations that I want to upgrade first before anywhere else. At the minute, these four AP's work on the 2.4Ghz G band.
how the new 1260's will work in the mixed environment. I believe I will need to purchase the 1262 (which is the dual band version) so that I can operate the AP in both the 2.4Ghz G band range and the 5Ghz N range at the same time, is this correct?If I was to purchase the 1261 (which is the single band version), will I only be able to operate in either th 2.4Ghz or 5Ghz, but not at the same time?
For the mixed environment, would you suggest the dual band version? Can I place the same SSID on multiple Radios if this is the case? Following example: Say I have the SSID called 'Company' - this at the minute is operating on the G band 2.4Ghz range. If I was to purcahse the dual band 1262, could I put this SSID on both the G radio and the N radio? Would clients with an N adapter automatically connect to the 5Ghz range (N Radio) and legacy G and B adapters automatically connect to the 2.4Ghz (G Radio)?
During BOYD implementation we faced some problems with Android devices:
1) The Netwrok Setup Assistant (NSA) download process corrupts during the self-provisioning process (captured on 4.1.1 and 4.2.2 version) 2) If NSA is already installed, the network setup process (downloading profile, certificate) stops at last step: connecting to network, meanwhile the connection itself successfully establishes. This bug is captured on 4.2.2 version, 4.1.1 is ok.
Google ACL is configured according to TrustSec docs and permits all traffic to google networks 173.194.0.0/16 and 74.125.0.0/16.
