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.

  • 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 ,

  • When issuing a 'show ip route' for a subnet which is not installed in the router's routing table, is it feasible to get the configured default route as the output/answer ?

    I thought it was even recall I've seen this before but when tried a couple of days ago didnt get the answer I was expecting... tried to find some documentations but couldnt. Thanks for any clue on this.

    Try  show ip route  10.10.10.0 255.255.255.0 longer-prefixes

  • The configuration of the replaced N7K module

    Hi, we had a module failed in the N7K, the failed slot is "slot-1" and the configuration about it was invisible because of the failure.
    So we migrated the configuration to another slot to maintain the business.
    And now we have just got the RMA module and are ready to install it.
    What I am worried about is after I replace the failed module, will the old configuration that was on the failed module appear on the new one?
    If so, since I have migrated the configuration, there could be conflicts that would affect the network.
    Hope for reply, thanks!

    Thanks for your reply, I still have a question:
    If, for example, my E1/1 port belongs to the failed I/O module in "slot-1", and had an ip address 1.1.1.1.When the module failed, the configuration about E1/1 became invisible because of the failure.
    Then I configured the port E2/1 on "slot-2" with the same ip address 1.1.1.1.
    When I replace a new and the same type of module in slot-1, the configuration about E1/1 with the ip address 1.1.1.1 would become visible again.(Here I am not really sure)
    Then my question is: will there be such a situation that within a device, E2/1 has an ip address 1.1.1.1 in "up" state and E1/1 has the same ip address 1.1.1.1 in "down" state?
    If so, what would happen if I active E1/1?

  • Configuring static routes at the network edge

    We have some Cisco 1750 routers at the edge of our network which are running RIP. We were advised to use static routes on the router, since there was only one route (across a WAN link) for traffic to go from the hub connected to the router, as RIP would only waste the limited bandwidth to the router. We posted this problem previously and got a response which stated :You could set up a default static route on your edge router, run RIP on your internal routers in order to propagate the default, but block the RIP to the outside.
    On your edge router, make a default route to your external link. Keep RIP running as before, but add the line redistribute static in your rip configuration. That will get the default route propagated.
    Now to stop the RIP on the external interface: If the link is on a different major IP network to your internal network, you can simply not include it in the network commands under rip. But if it is in the same network, then RIP will be enabled on the interface, so you will have to add passive-interface xxxxx, where xxxxx refers to the interface carrying your external link,
    Alternatively, you could define your default route using the ip default-network command. This will get propagated automatically into the RIP even without the redistribute command.
    We tried it, the problem is that the router is unreachable, via the serial or Ethernet, although if connected to the router via console port, with the configuration screen , you are able to ping external locations, and are able to telnet into the router, but he PC's on the Ethernet side of the router cant see the network.
    Assistance\Advice requested.
    attached you wll find , the actual reply , and a copy of some info from our work file.

    I have looked at the config that you posted and I see several issues. The serial interface on Salvage is 172.20.2.2. Your message indicates that it is connected via serial to a 3640 which your message seems to indicate is 172.20.1.4. But that makes the 3640 on a different subnet. Connections over a serial link should be in the same subnet on both ends. (The exception to that is when you are using the ip unnumbered feature - which you are not). I suspect that part of your problem is that the routers do not see themselves on a connected subnet. When you run RIP over the link it can compensate for that to some degree. But when you stop RIP the problem has impact.
    Also I see that you have a static default route as Kevin suggested. And in RIP you have redistribute static. But there is no default metric defined. To redistribute into RIP you need a default metric. Another aspect of the problem with the default route is that the next hop for the default route is 172.20.1.4, but without RIP running I believe that Salvage has no idea how to get to that address. You can confirm this by doing show ip route 172.20.1.4 on Salvage. I suspect that you will get an error about route not in table.
    Beyond these issues I believe that there is a larger problem of misunderstanding. When I look at your original post in this thread it talks about not running RIP over the serial link. And when I read Kevin's response the first paragraph is describing not running RIP over the serial interface when it says do static default on your edge router and run RIP on your internal router. If you are not running RIP over the serial interface then I see no reason to run RIP on Salvage at all. There is one piece of this that Kevin did not address. If you do not run RIP over the serial link then how does the 3640 know about the Ethernet subnet at Salvage. I believe that the answer is that the 3640 needs to configure a static route to 172.20.27.0 with the 1750 serial interface as the next hop. And if there are other routers that the 3640 communicates with via RIP then the 3640 needs to redistribute static into RIP (remembering to have a default metric).
    If you address these issues I believe that you will have connectivity from the central network to the remote subnet on Salvage.

  • Send the Configuration via TFTP server to New Router/Switch

    Dears,
    I need to apply a policy that for any new router or switch installation, specific configuration will be sent to these devices through one centralized TFTP server which comply with our configuration and rules, this is to avoid any miss configuration from the team and control the junior network Engineer to add any wrong configuration that can effect the network, is this possible?

  • Replacing the DMVPN hub router

    We are replacing our current 2921 router, Version 15.2(4)M2, with a 3925 Version 15.2(4)M6. It is the DMVPN hub router for 6 spoke routers. We cut and pasted the configuration from the old router to the new. We confirmed internet connectivity from clients on the inside. But none of the DMVPN tunnels will set up. As we were in a very short maintenance window we did not have a lot of time to troubleshoot and had to revert to the old router. Is there some procedure we need to implement to force the tunnels to come up?

    Because you are changing the Hardware and copy past the config. Spokes will not re register themselves at HUB until you reset them again. Then they will register themselves again in the NHRP table at the new HUB..

  • 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.

  • Imac is no longer able to open the Configuration file

    Hi ,
    I have an imac ( ilamp) 20' connected to ADSL, via Netopia Router which is connected to the Airport extreme connected to imac, for the PB Aluminum Tiger 10.4.5. we both can connect. PB can print via imac/printer.
    The imac is no longer able to open the Configuration file, when i enter the pswd which is correct, i get the message "The Airport Admin. Utility was unable to read the configuration of the selected base station an error occurred while reading the configuration "
    My Beau updated Airport to V5.7, this is the first time since the update I've tried to access the conf. file for the imac which i have done numerous times prior.
    I have a new base station Ip address 254.128.0 in Airport Utility Admin, on the imac which does not reflect my network settings anywhere, and is not what it use to be, i think, it was one value different than the PB.Base station IP. I do not know how it changed neither one of us changed it.
    I tried using the Airport Setup assistant (imac), I received this message:
    "Appropriate Airport hardware was bot found on this computer,if you recently
    Installed, an Airport card,please shut down your computer$ make sure the card is properly istalled."
    The imac does not have a card, nor do i think it needs one.
    I would like to be able to at least open the configuration file.
    Thank you for reading my post.

    Hi Kes, a star for the company !
    I made an error on my first post I have a Netopia modem, Airport router.
    And so it remains, i guess that there must be an easy answer somewhere
    that I am missing that I/we should read, some direction to that would be helpful, and I would be very appreciative.
    As I said the password had been set, and it is not an issue of that being forgotten, i wondered if it was changed back to "public" tried, not it.
    particular because everytime the imac wakes one of the folders on ( no one else in office just me and boyfriend and it is his work folder he has a copy on the PB.( the folder on desk top has been clicked on, the one with sensitve info, i have backed the folder up and secure trashed it, just in case some security issue hacking has taken place, thats closing the barn door after the fact.
    Good luck,w/ this Q.

  • Can't Connect To The Internet Or Router

    I have had my router set up for about three years.  It's always worked perfectly fine until the other day. I think that the router just died, but I'm not sure and I want to try and fix this one before I just go out and buy a new one.
    Basic Background Information:
    Model No:WRT54GC
    -The router is and always has been hooked up to a surge protector and there haven't been any other recent surges in my home.
    -When the wireless router is connected to the computer (using a functioning Ethernet cable ) I cannot connect to the internet or the router.  (I can't even put the IP into a browser and bring it up.  I also tried the factory setting IP, just incase it actually did reset, and that doesn't work either.)
    -When the router is plugged in I can't see it from any other wireless computer.  (I also checked for any new signals and did not see any after I reset the router.)
    -LEDs look like:
          *Power = solid green
          *Internet = solid green 
          *wireless = hard to tell - doesn't look like it's on at all
          *all other Ethernet pluggins = solid green
    What I've Tried So Far:
    -I couldn't connect to the internet so I plugged the modem directly into my computer.  -->  The internet works.
    -I tried unplugging the router, waiting, and then plugging it back in.  -->  I couldn't connect to the internet or the router.
    -I tried the reset button.  -->  I couldn't connect to the internet or the router.
    -I tried leaving the router unplugged all night and then plugging it in and starting the process all over again.  -->  I couldn't connect to the internet or the router.
    -I also tried downloading new firmware, but since I can't connect to the router through any of my browsers I am unsure how else to update the firmware. 
    Thanks in advance for any help!

    Try upgrading your Router's firmware and then you can reconfigure your Router from the scratch...
    As you are not able to go online through router...you have to download the formware by connecting computer to the modem..
    Go to website linksysbycisco.com/downloads.........insert model no of your router in serach tab......select proper version of your router........download the firmware file......save that file on desktop
    Now reconnect the Modem to Router on Internet Port and from Computer to Router on Ethernet Port 1and now Press and hold the reset button for 60 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...
    Now you can upgrade the firmware using TFTP utility...Download tftp utility.
    Follow these steps to upgrade the firmware on the device : -
    Double click the TFTP.exe file and click run.
    For Server- Enter the IP Address of the router that you assigned.  By default, the router is 192.168.1.1...
    For Password- Enter the password you assigned the router. By default, the router’s password is “admin”.
    For File- Click the triple “…” button and browse for the .bin firmware file...
    Click Upgrade button to start upgrading.  A progress bar should show up to show the progress.
    Once the Upgrade is done press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...

  • Using Extreme in Bridge mode, can't see the DHCP clients if the D-Link router

    I have an Airport Extreme attached to my DLink modem/router.  I have configured the Airport Extreme in Bridge mode, and I was expecting all clients to show up in my D-Link router.  Although the configuration works most of the time, I have been experience a few issues:
    1.  From time to time, computers attached (both Windows and/or Mac) complain about an IP address conflict.  I can ignore the error and it works fine.
    2. From time to time, I loose Internet connectivity, and I need to disconnect my computer and reconnect again to solve the issue.  This is not necessarily linked to symptom #1
    3. On my D-Link router/modem (which I only use to connect my Airport to my ISP), if I check the DHCP clients, I can see the Airport router connected and *some* of the wireless clients that connect through the Airport.  The list changes quite randomly, and at times, I see the airport appearing twice with different IP addresses.
    Any help configuring it "right" will be appreciated!
    Alain

    When the AirPort Extreme is in bridge mode, the AirPort Extreme is simply passing through the DHCP settings and services that are handled by the D-Link modem/router.
    In other words, the D-Link device is in total charge of the DHCP services for devices on the network.
    You might want to check with D-Link support to see if they have any recommended practices for configuing the modem/router when another router....the AirPort Extreme in this case....is being used in bridge mode on the network
