model orientation of 2821 router please?

I need to upgrade the ROMMON to correct a problem of vulnerability (PSIRT: 62573_FN_62573_RouterAS535) and I try to load the file recommended ' C2800NM_RM2.srec.124 - 13r.T5 ' in our 2821 routers... can someone tell me what directory to put in it please?  I tried everything I can think of without success. Just, he's missing, use my TFTP try again and then abandons the session. Thank you! Best regards, Michael

Hi Michael,

1. instead of upgrade the ROMmon to 12.4 (13r) T5, please consider upgrading to version 12.4 T11 (13r) that this version is the ability to allow the router to boot via USB.

2. can you have physical access to the router? The router has two USB ports, you can put the IOS in a USB key (as it has supported and correctly formatted).

To apply the upgrade ROMmon, the command is:

TFTP: upgrade the rom t fileftp: / //filename

USB: upgrade the rom usbflash0 file / 1:filename

In all cases, you will be asked a yes/no question, and if you press on 'y', the router will upgrade the ROMmon and recharge.

    Walt

    The problem is probably that the Linksys E1200 is a wireless-N Router and your former Office no doubt has a wireless adapter that is only capable of wireless-G (or perhaps Wireless G and B).

    Are adapters wireless in your other computers wireless - n?  If so, it perhaps is the reason why they could not connect to your old G of Netgear wireless router.

    You can get a new wireless-N for the office adapter or configure the E1200 wireless g available.

  • 2821 router to access T1 on LAN

    I'll put up a Cisco router for a T1 line for the first time and I hit a barrier. The router, a 2821 with WIC-1DSU-T1-V2 is online (all statuses are rising and I can ping outside sites). However, a laptop computer connected to the router can not access the Internet outside.

    My router (sterilized) static IP from the ISP is 10.0.0.222. It is on the 10.0.0.220/30 network, with a broadcast address of 10.0.0.223/30. The ISP gateway is 10.0.0.221

    I have the Gigabit Ethernet port game with an IP address of 192.168.1.1/24

    Here is the configuration:

    Since the router command line I can ping 10.0.0.221 (Gateway ISP) as well as external IP addresses. Domain names resolve correctly and can be crazy. I ping the router of my regular Internet connection.

    However, when I join a laptop the GigabitEthernet0/1 (static IP address of the laptop is 192.168.1.2) I can't seem to the outside network. I can ping the map T1 and Ethernet card address, but not the ISP (10.0.0.221) gateway or all other external addresses.

    I tried to adjust laptop, gateway 192.168.1.1 and 10.0.0.222. Set to 10.0.0.221 gives an error "network unreachable".

    I am new to Cisco routers, so I guess it's something simple, maybe an IP need rule of routing or something?

    In summary: the router is online on T1, can ping and ping, but laptop connected to the ethernet router cannot be accessed outside the network.

    Thanks for any help.

    Hello

    I guess the problem is that your ISP does not know how to route the packets back to your 192.168.1.0 subnet. If you ping the router with the address of the source of your inside interface it will confirm if this is the case or not.

    You can run a dynamic routing with your ISP Protocol which I guess is not the solution preferred the complexity. You can ask the ISP adds a route to your network, but again once I guess that's not an option.

    The most appropriate solution would be to run NAT Network Address Translation on your serial interface and use overhead NAT to translate entire your network to your unique WAN address.

    Hope that helps.

  • 2821 router support

    Dear Sir.

    Praposed connectivity for voice between neighborhoods General remote IP phones to analog phones is regarding the attached flowchart. Cisco 2821 routiters with IOS 12.2 are interconnected (v.35) line using rented between HQ FOR REMOTE SITES. To remote sites analog phones are connected to the FXS ports. To end HQ PABX with the required number of user liseces for IPPHONES is connected to the router via an ethernet switch. It is the installation of the network shown in the diagram is correct for connectivity you want between phones ip HQ for analog phone of BRANCH. What should be the requirement of configuration in the router for connectivity abive.

    Please give me some examples

    Thank you & best regards

    Srinivas

    Hello Srini,

    your lab configuration is similar to what I guessed.

    the IP PBX has an IP address on the same subnet IP to the lan from 2800 HQ interface.

    You can run a routing protocol on the V.35 point - to - point link in order to advertise the subnet LAN of HQ.

    In addition to what was already mentioned in my first post the use of QoS for a priority queue VoIP calls is recommended.

    The part of QoS can be added later to the installation of laboratory.

    Hope to help

  • [Noob questions] Model oriented programming OBJECT and event Flex

    Hello, I have two very easy questions for an expert - I think.

    (1) issue-oriented object

    If I have a

    UserElement extends the Image

    UserImage extends UserElement

    UserText extends UserElement

    ...

    UserSomething extends UserElement

    Each UserSomething derived from UserElement has an editElement method that can be placed in the superclass UserElement needs to look exactly because in this journal.

    Now, from the root of the Application, I have to call the editElement, but I'd rather not be forced to have a giant switch inelegant structure... There is a way to dynamically cast to the right class?

    (2) issue of event model

    I read the documentation and googled around, but if I have this structure

    Application

    Canvas1

    Control1

    Canvas2

    CONTROL2

    and I send Control1 event, the full path is Application > Canvas1 > Control1 > Canvas1 > Application. But if I need control2 to know that this event is FAILED, the only way I see is to call a method in the Application control2. Is this correct or there is a way to redirect the event in a way to broadcast?

    Thanks in advance for anyone who wants to answer

    maestro91,

    Answer, no, protected Alexander is very good and I used it in this way - protected is visible to inherited classes OK.

    You should be able to:

    var r: derivedClass;

    a = new derivedClass();

    function do_something (b: baseClass)

    {

    test to find out which class that I was adopted, then derived

    ((derivedClass) b) .editelement ();

    above must call the correct method

    }

    You must explicitly cast to ensure the right call gets shot, but you used baseClass as an argument, so you can send your derived through classes.

  • HP C4580 not scan to PC. I need help to configure my Netgear router please :)

    Hello

    I've read here, the threads that talk about this printer prints only not to or from a PC - my problem is that the C4580 go scan from my PC, but will not scan to PC.

    I found an answer from someone who has had the same problem earlier this year, but I do not understand what to do.

    Here's the answer:

    "I have ordered mine entering the settings from my router (Netgear) page and setting the built-in firewall rules. "The internal firewall was blocking the printer, I could print, scan using the computer, just could not scan from the printer to the computer.

    Also, I have a Netgear router, but could do with help on how to do the same thing as the person above.

    Thanks in advance for any help!

    Sorry, I don't need help after all

    It was not the router requires a configuration, it is the firewall that was a block that should be changed to "allow".

    My "all-in-one" now does everything it is supposed to do

  • Drop ' n Go subnet to breast pre-existing network - Help with routing please

    Hi all

    I consider myself the best entry level when it comes to the Cisco ASA 5505, and I appreciate help or direction that someone would be able to provide regarding this question, I'll have. I'm sure there is something out there for this, but I was still not able to understand this with what I found.

    We currently have our installation of infrastructure like this: modem(69.14.72.6/255.255.255.248)-> ASA (192.168.1.1)-> Switch-> hosts and Servers(192.168.0.X\24).

    What I'm trying to do is to drop in a small router somewhere within this network with its own subnet and be able to communicate back him 192.168.0.X network, so it will look something like this: modem-> ASA-> Switch-> hosts and Servers(192.168.0.X\24) & hosts and Servers(192.168.1.X\24).

    I will allow this traffic if all goes well, then that only have 2 interfaces configured on the SAA (0/0 and 0/1-0/5 inside) outside and without changing the configuration of the switch. A few key phrases that come to mind from my research so far are "Hair pin" and "permit same-security-traffic intra-interface". Also, I am aware of the port-forwarding and as I understand it would not as convenient to configure a rule for each device connected to the 192.168.1.X\24 network.

    I hope someone can help me with this question, I've been at this for 3 weeks now.

    Thanks again to all!

    EDIT: Here is a diagram to help explain what I'm trying to do. The area in red is what I'm trying to add to the others that I already have.

    Hi James,

    For the route between the 2 networks, that you will need to either use a layer 3 switch or a "router on a stick".

    Installation of a layer 3 switch would interrupt less to your existing network.

    You are then ASA "inside" interface--> Layer 3 Distribution Switch--> 2 or more switches to access

    We need new models of import to import us master records point, bills manufactured and prefabricated ranges in R12.

    Can anyone guide hoe to develop and create new import models to include the new fields in R12.

    For routing, please develop a model that allows the import of the operation Standard code, if it exists, but also display on the model columns / fields required if code no. Operation Standard is available.   Let me know if any questions.

    Hello

    You can download your data in Excel to a staging table using sql * loader or any other tool.

    After downloading the data, you must complete the interface tables in my previous post.

    After the filling of the interfaces, you must run the program BOM & Routing simultaneous Import to import legacy data.

    For more details, please visit the following links.

  • router to router 2821 encryption

    How to secure this scenerio?

    (1) site A has a 2821 router and an IP connection to the site C. 2821 on another organizations IP network.

    (2) site B has a router 2821 with an MPLS connection at the site of the C-2821.

    It's pretty easy to connect and get plain text connections and tunnels WILL work, but I'm leaving my network open to other agencies or MPLS service provider.

    I think little flavor of encryption between routers with tunnels GRE routes real traffic.

    Thank you in advance for recommendations and examples of config.

    Hi Tod,

    You can deploy a separate acl on the physical interface, which allows only the tunnel itself (udp/500 and esp). The ACL in the VTI would control the traffic through the tunnel.
