Network Management Systems
Apr 7, 2011
Deploying monitoring systems, typically in NOCs and maintaining them and creating modles of customer networks working with SNMP polling systems. Tools include applications like HP NNM, Netcool, Ciscoworks etc. How far would a career take you if specialising in this area? It seems like a diversion from the typical Routing/Switching side of networking. Not nessacarly from a technical perspective, how about networking? Ie; being exposed to migration/project teams who wanting to 'migrate' more hardware and sites to the care of the NOC, after the design teams have implemented them? This seems like a step towards the design side which in the long term I am wishing to get to.

I have two Windows 7 Ultimate computers and around 10 Windows XP (Home and Professional, SP2 and SP3) computers trying to connect to it. It's just a LAN (no internet access).I have set all of the password-protected sharing off on the Win 7 systems. I have tried opening up ALL of the permissions and such (since security is not really an issue).When I try to map the network drive, it won't let me merely connect to it. So, I have to click map network drive on the XP computer and hit "login with other credentials" and enter the username/pass for the user account on the Win 7 machine (we'll say Bob for user and Smith for password for the sake of example). It will mount the share (which is actually the C: root of the drive) just fine.
The only problem is the moment you restart the Windows XP system, it will lose the connection. My fix for it was to create a .bat file that contained the following: [code] I put it in the Progam FilesStartup folder to run upon boot. For the most part, it seems to work after a fashion. Some of the computers, though, will drop the connection to the two Windows 7 systems and need to be rebooted 1-2 times before they get it back again. Even clicking the .bat file manually will have the same result (you will have to reboot) if it drops the connection while you're using it. Plus, sometimes it doesn't map the drive correctly (I assume because the batch file is running before the connection has a chance to initialize on the LAN).I've also tried adding an "Everybody" user to the permissions on the Win 7 systems with full access, but it only seemed to cause problems with the existing connections.It might also be prudent to mention that both the Windows 7 and Windows XP systems are all 32 bit. I've also disabled the firewalls on the two Windows 7 systems. Neither of them have any antivirus or security software installed.

Have Win7 and XP systems in my network wire connected to the router. When IP of both systems are not reserved, each computer can see other network computers and devices, five in total.A good thing that both systems get each time same IPs which even got not changed since I upgraded from E1200.When I reserve an IP for each system exactly that they currently have, both systems loose ability to see other network computers. Network shares not affected, I still can remotely access my XP box remotely from my 7 via RDP by computer name. WDTV Live wirelessly connected to the router can get/update its IP address (no connection issues) but same as others cannot see network resources.
Tried different ways, rebooted, finally ended up with device reset pushing the button.The next day I managed to reproduce the issue, but was able to revert by disabling/enabling of DHCP server.Another issue I got with an external HD connected to the router when some files got converted to folders by uTorrent started from that drive.I had to use Unlocker application to be able to delete folders converted. I can just assume that issue because of anonymous access was enabled to the external disk. No problems when same HD connected to PC USB.

I show up at this business. They have about 40-50 systems. They have a 2003 AD server with a router, and 4 switches. There is also a dvr system on the network for cameras.Each switch is daisy chained together. Everything is working correctly except for the fact that the network drops about 5 times a day. Before they called us, they would just unhook one switch and plug it back in and it would work.At first, we took that switch and exchanged it with another switch in a computer lab to see if just the computer lab goes down. If it did, then that switch was bad. That wasn't the case, the whole network still went down.We had already left, but when we go back, our first choice will to see if there is a loop anywhere within the switch that will flood the network. Then, we were going to see if there was a switch that was getting a lot of traffic on the network to try to track it down.

I have a few laptops at home and one desktop. I also have a work laptop which I carry to work every day. I have a lan at home. The computers are connected through a wireless router though my pc is connected through a lan cable. We are able to share files and content.
I sometimes connect my office laptop at home. Though the laptop connects to the network but I am unable to transfer or share files to other computers running Windows Vista/7. After a bit of research I figured this is because the workgroup name of my office laptop is different than the systems at home. I dont want to change the workgroup name of my office laptop as it will create problems at work.
How can I connected my office laptop to the network and transfer files if the workgroup name is different? It does show names of computers on network but when I try to connect a username & password box pops up.

I have recently installed several of the new WS-500 series switches into my networks and much to my surprise they are not supported by the CNA tool as the older 500 series were. I tried using the CCA tool, but my routers and legacy switches are not supported under it. One of the reasons I bought the Cisco switches in the first place is because I wanted to use one tool to manage all components in my network. I feel rather irked about what seems to be a purposeful hampering of functionality of the SMB line of equipment. Is there a management application that will allow me to manage all of my Cisco devices from the same console?

I'm trying to add an extended ACL (120) to an 800 series router (887) using Network Objects to allow the management user IP range full access to IP services and restricted access to email only for standard user IP range. However as soon as I apply the ACL to the outbound of my Vlan no matter what is in the ACL my PC looses internet connectivity. I've tried adding an explict allow for my IP address and still no access so I'm thinking possible a NAT issue, please have a look at my attached config and let me know what you think. Would I be better trying to control data flow with ZBF? I want to restrict standard users to email access only during the work day with web access and IM access after hours along with blocking all P2P programs for standard users at any time. Management group will have unrestricted access to all IP protocols. My original plan was to use time based ACL's!

I am using my normal Ethernet cable that I used on my old PC at the exact same location / circumstances, but when I plug the cable in my new PC, my download speed peaks at 81.5 kb/s and my upload speed peaks at 10 kb/s. Now when I put it back in my old pc I get 3mb/s download speed and 0.5 mb/s upload speed. I don't quite understand what the problem is. Do I need to update drivers/BIOS? I can't find any updates. This is a clean install of Windows 7 Ultimate 64 Bit with barely any programs installed as of yet. I have reinstalled Windows 7 aswell, to no avail.

I have an issue where I am trying to start my VPN and continually get the following message: Error 56: The Cisco Systems, Inc. VPN Service has not been started. Please start this service and try again.
So I have been into Services to 'start' Cisco Systems, Inc. VPN Services - this then always comes up with this error: Error 1053: The service did not respond to the start or control request in a timely fashion
The solution mentioned on other posts on disabling the ICS but it was already disabled. When I try to start VPNGUI I also get error 56 and when I try to use services.msc to start the service I get error 1053. Then also when I try to start from task manager services(cvpnnd) i get access denied.

I use campground WIFI systems to get internet/email but some wifi systems have limited range.I solved this problem with a booster antenna but that means I am hard wired to it. I want to (if possible) to get the wifi signal to a bridge then send it to a router so that I can use my lap top, printer and other devices in my 5th wheel wirelessly. I looked at a suggested system that uses a point-to-point antenna that feeds a bridge, that feeds a router. I don't want to use the point-to-point antenna.My booster antenna is a USB feed.

Any quick breakdown on the differences between some Network Management software titles. I dont know when you would use each one or what the limitations are of each. [code] I have been looking over the release notes for each product trying to draw some conclusion on which titles support or dont support certain products.
When you would use each and if there are any gotchas or limits to watch out for? It looks like Prime is a paid for product but will any of the free solutions (CNA, CCP, CCA) work with all enterprise level products (2950, 2960, 3560, 3750, 4948, 4900 4500 switches and 1800, 1900, 2800, 2900, 3800, 3900 routers) or do you have to use Prime to get a product that will mange these devices?

I have a requirement to preserve markings end to end across a network utilising 3750X switches, I am marking the packets without a problem, but due to the rewriting function the marking is being overwritten by ther COS-->DSCP maps.To simplify the scenario I have set up a test environment (see Diagram) and am using ICMP as a simple test using ICMP to test with Both 3750 have 12.2(35)SE5 3750-1
mls qos
mls qos rewrite ip dscp
ip access-list extended ICMP
permit icmp any any
Class-map ICMP
match access-group name ICMP
[code]....
I have used wireshark to verify that the packets are being marked, with the' mls qos rewrite ip dscp' they are, without rewriting does not occur.Moving my sniffer to the 3750-2 I am monitoring the Layer3 connection (marking preserved), however on the layer 2 trunk the marking has been reset to 0 , if I remove the 'mls qos rewrite ip dscp' from 3750-2 then I see the marking on the layer 2 trunk, however I am then unable to remark anything generated on this switch. I believe with the 'mls qos rewrite ip dscp' enabled the L3 to L2 transistion removes the IP DSCP sets the COS to 0 and themnthe COS to DSCP mapping ensures the DSCP is set back to 0.I have tried implementing additional marking policies on 3750-2 but to no avail.What I need is ensuring that that a frame / packet marked in 3750-1 can keep it's marking to the end system over layer 3 and a layer 2 trunk. The only place I wan t the marking to be stripped off is when the dot1q tag is removed as it goes through an access port.

I would like to push route for admin services (Vlan20) to bypass the firewall via an other connection (CSI to CSE). So my first choice was to create a route-map in (CSI) but I don't know how to do it. On my Firewall ASA, I don't have any Context License, that is why I would like to do it like this.
I have included some part of my initial configuration CSI and CSE and diagram.

Which values should I take, to calculate UPS systems capacity? And also I am interesting when 4500x has two power supplies what is power consumption?
