CF Card 2821 Router

Is there a way to have the router be able to boot up without the CF card installed? It seems when I take the card out the router will not find the IOS. I am new to the 2800 so I am trying to figure this out. Thank you.
-Nick

2800 stores its IOS in flash and hence when you remove the CF, the router will not boot and would return to ROMMON

  • CCP Express wont install on 2821 router

    Hello everyone,
    I am trying to install Cisco Configuration Professional 2.4 Express on my 2821 router. During the installation process, I get notified there is 0 bytes available of routers flash memory. When I run a "show flash:" command, I receive the following error:
    %Error show flash: (No device available)
    The output of the "show version" (edited) command is:
    Cisco IOS Software, 2800 Software (C2800NM-ADVENTERPRISEK9-M), Version 12.4, RELEASE SOFTWARE (fc1)

    After some reading on Cisco site, I saw that 2800 routers do not support internal flash, but only CF cards. What I would like to know is how can I install CCP Express on CF card?
    Thank you in advance.

  • How to program the daq card to route signals?

    Hi,
    I would like to program the daq card to route signals, for example from DIO0 to
    DIO1. All this should happen without Labview, directly on the board. Is this possible?
    What I want to do, is to get a lot of signals as inputs and output those
    signals as they are. Sometimes I need to take one signal through Labview
    and make some modifications to it. If I route all the signals through Windows
    and Labview will propably cause latency, so I would like to do this at the lowest
    level as possible.
    Currently I'm using PCI-DAQ 6025E, but this card might not be sufficient for our
    needs, so if this is possible with some other card, please share your information.
    All information on this matter is highly appreciated.

    Oops!. I just noticed that I accidentally posted this question to the wrong forum.
    I posted a new one to "multifunction DAQ", so if you have something to say about
    this matter, then go here

  • L2TP network server 2821 router?

    Can 2821 router with appropirate IOS image be L2TP network server and support 400-500 L2TP simultaneous connections? We want to use access VPDN that uses L2TP as tunneling protocol to provide remote users access to our services and to the Internet.

    Hi Marija,
    That's right, the 2821 can be used as an L2TP server (LNS or LAC).
    It supports 900 IDBs, which means that you can provide access to around 900 remote-users. Also, it supports a maximum of 880 L2TP sessions/tunnels.
    You can find detailed information on the following link:

  • 2821 Router with EVM-HD-6FXO

    Hi all,
    I want to buy a 2821 router with an EVM-HD-6FXO module. The 2821 is running IOS "c2800nm-ipbase-mz.124-15.T10.bin". My question is can I use the 2821 as a Gateway for CUCM v10.5 or if I have change upgrade the IOS to a different version.
    Thanks.

    Yes, run SIP or H323 which is version agnostic, even MGCP will work though according to Cisco 15.X code is required.

  • How to view Log on the cisco 2821 Router

    Hi,
    can any one help me  to view the Log on the Cisco 2821 router for any  issue occur.
    Thanks,
    Saroj

    Cisco devices use the syslog to manage system logs and alerts. But in Cisco devices there is lack of large internal storage space for storing these kinds of logs.So to overcome Cisco devices has the following two options:
    1) internanal buffer — That is a small part of memory buffers to collect log the most recent messages. The buffer size is limited and , when the device reboots, these syslog messages are lost.by default it is on
    (If not follow this steps
    conf t
    logging on
    logging console.....console logs
    logging buffer  size ......set the size of buffer
    terminal monitor.......to gets logs on the remote terminal like telnet,ssh etc.
    sh logging.........to see buffer logs.)
    2) Syslog server—  By using this we can send messages to an external device for storing this logs and the storage size does depend on the available disk space of the external syslog server. This option is not enabled by default.
    If you have any syslog server please find the below simple config .
    conf t
    logging host x.x.x.x
    logging traps (i.e 0 1 2 3 4 5 .. according to your requirement)
    before enabling logging be sure that your router is properly configure to collect proper time from any NTP server or manually configure to get time
    command to set time manually on router is (set clock ) or to use ntp server use ntp server x.x.x.x to sync clock to router router.
    Hop thant is informative ,

  • Cisco 2821 Router as a NTP Server

    We are using a 2821 Router as our boundary router.  It has installed into it a 9 port HWIC for layer 2 switching as well as allowing the router to communicate on the Network Management VLAN.  All of the devices on the Network Management VLAN are segregated from the managed traffic, which unfortunately also doesn't allow them external NTP services.  Can the router be programmed as a NTP server so that all of the network appliances can utilize it for NTP from either it's NM Vlan IP address or from a loopback address?  Thanks in advance for the help.

    What are the commands needed in the router for it to provide time to other appliances?
    If your router has successfully synchronized with an authoritative NTP server?  NOT A THING.
    In my network, only the site's distribution switch is allowed to go out and get NTP.  All other access switch goes to the distribution switch by using the command "ntp server ".  You can have multiple NTP server IP address and if you prefer to have a "favorite" you can append your command with the "prefer" option:  ntp server prefer.
    If you have clients then point their NTP to your router.  For troubleshooting, I prefer the command "sh ntp associate".  If your NTP server IP address starts with a "*" this is good and means that your NTP is synchronized.
    Hope this answers your question.

  • Cisco 2821 router IOS and Ipsec

    Hi all.I was wondering can you create VPN tunnels using Ipsec on a 2821 router if you have only the IPBASE image(the basic image 2821 router comes with) on the router or do you need some other version of IOS?
    I've gone totally nuts trying to find out but can't seem to find an answer.Thanks in advance.

    Igor
    You can not create IPSec tunnels if the 2821 is running the IP BASE image. You need a feature set that supports crypto to do IPSec. In general image names that include k9 in the image name will support crypto. You probably would want the Advanced Security feature set or the Advanced IP Services feature set, both of which do support crypto and do support IPSec tunnels.

  • Cisco 2821 router won't keep config

    Hi
    I have a cisco 2821 router that i'm trying to load a config on and for some reason it will not stay once i reboot it.
    I can get the config on and give it a host name and everything that i need but when i reboot it goes back to
    router> as the host name and no config on it.What would be causing this problem as this is my first time seeing
    this before and thanks for your help in advance.

    Check your config-registry using the "sh version" command.  It should be 0x2102 and you can change this using the command "config-registry 0x2102" and a reboot.

  • Fast EtherChannel between Catalyst 3750 and 2821 Router

    Hi Guys
    I'm trying to setup a Fast EtherChannel between a cat3750-smi and a 2821 router that consists of only 2 links.
    I am following instructions per TAC, but I'm getting an error along the way;
    On the cat3750:
    interface port-channel 1
    no switchport
    Command Rejected: Not a convertable port
    Can anyone help???
    Also... do the IP Addresses for the EtherChannel need to be the same for both port-channels? Or do I assign the switch like 192.168.1.1 and the router 192.168.1.2 ?
    Thanks!
    Adam

    Hi Adam,
    The ip address cannot be same but it should belong to same subnet. So one side 192.168.1.1 and other side 192.168.1.2 will work fine.
    Its better to convert your layer 2 port as a layer port fist so what you do the port which you want to be port channel go that that interface and convert with "switchport" command
    once it is a layer 3 port configure with channel group and automatically layer 3 port channel will be created and you can sssign an ip address then.
    Just give a try and update if it works.

  • WAAS network module and 2821 router?

    What WAE network modules will work in a 2821 router? This 2821 has a dual-T1 Multipoint connection back to our data center and I know that the users will benefit greatly from WAAS, but I'd rather not have to upgrade the router to a 3800 just to install a WAE module

    NME-WAE-502 will give you full functionality with the enterprise licence. This is the NME that is the most widely used for WAAS.
    NME-WAE-302 is available, but only supports the transport license which give you TCP optimizations only (no application AO support).
    NME-WAE-522 is only supported in the 3800 series routers.
    Hope that helps,

  • Linksys Wireless Card (Linksys Router) in G4 Power Mac works fine until...

    Linksys Wireless Card (Linksys Router) in G4 Power Mac works fine until...
    new software upgrades on the 14 August 2006 (yesterday) which includes Airport 4.2.
    The Linksys wireless PCI card (WMP54G) was installed just under a year ago with no problems. There was no need to install drivers, the Apple Mac recognised it and used it as a wireless card. I was browsing the internet last night (14 August) and the software updates downloaded in the background. Once it finished downloading, it requested for a re-start. I carried on browing the internet and then switched off my machine and went to bed.
    When I turned on my computer in the morning, the wireless card no longer activates. The computer recognises there is a card but there is no connection to the router (meaning no internet). The router settings have not changed at all.
    I believe it could be the Airport 4.2 update has interfered with the Linksys Card, but I'm not sure. I've been through all the Assist functions etc and there is no luck. It does seem that the big update released on the 14th August has played its part.
    Any opinions and assistance on getting the card back to normal, and if possible assistance in removing the new updates to previous drivers/settings.
    Thanks people.
    G4 Power Mac Dual Processor Mirrored Doors   Mac OS X (10.3.9)  

    Sorry, I do not have a solution for you but I have the same problem upgrading from Jaguar to Panther (on my home machine not listed which is a G3 b&w). Now my WMP54G doesn't see any wireless network (I used to be able to see several in the 'hood), and Apple Profiler recognizes the card. Apple updater changed the Airport system files, I believe.
    Is it possible to find the old Airport software and install over current system to get it working again? I doubt Apple still offers the old airport software, but if someone has it, maybe it can be installed with Pacifist.
    We need some wireless help here, community.

  • 2821 Router with wic-1ADSL card

    I am trying to verify a code that will recognize a WIC-1ADSL card in a 2821. The Cisco Software tool page shows that 12.4.10 IPVOICE code has support for this but the card is not seen on the router. When I try the enterprise version 12.4.9(T1) It does't see that card either but shows a VPN module??
    Does anyone know what release will work? I am replacing 2620 routers (12.3.19) that have these cards in them for Disaster Recovery. I need support for ADSL- Asymetric Digital Subscriber Line support.

  • Migrating the configuration 2821 router to 3925

    Hi ,
    I need help am planning to migrate the configuration from 2821 isr to 3925 , i want to know is there any challenges are there while migrating.

    Hi Vasant,
    I think there will not be any major challenges in migration just you need to consider the type of card and link you are using on the router. However use the below link that will give you the major techspec difference in ISRG1 & G2 routers.

  • WebVPN on 2821 Router

    I have had my WebVPN working fine on my 2821. Now yesterday my ACS server died and I had to load it on another server to get stuff back up. I had my router setup wrong and had to get into the router using ROMMON mode, changing the Config-Register, etc, the ugly way. I got the AAA turned off and can now access the router. However, my WebVPN no longer works and I was thinking I had this issue before and I had to do something with re-creating my certificates, keys, etc.
    Anyone have any ideas? I am all out at this point.

    Hi Jonas,
    Yes you can use different permissions for different group of users depending on where  your users are located , for e.g locally on the router or on radius server.
    If its there on radius server, then you can push down some attributes and map it to use specific policy group or if users are created locally then you can use aaa attribute list.
    The following is the document for your reference:-
    http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6586/ps6657/prod_white_paper0900aecd8051ac3a.html
    Also lets take an example,  for local user on router
    aaa authentication login list SSL local
    aaa authorization network localauthor local
    webvpn context SSL
    policy group policy_1
    policy group  ABC
    default-group-policy policy_1
    aaa authentication list SSL
    aaa authorization list localauthor
    gateway gateway_1
    inservice
    aaa attribute list ABC
    attribute type user-vpn-group "ABC" mandatory
    attribute type webvpn-context "SSL"
    username cisco privilege 15 secret 5 $1$A840$hEkdXCQJRuPC3U5O8N3Gd0
    username cisco aaa attribute list ABC
    User cisco will be binded  you use the policy as ABC and context as SSL and if  there is no condition user will use the default policy policy_1.
    I hope it helps.
    Thanks,
    Shilpa
