I have one new cisco 2921 router but after first login into the new router . I have made some configuration but forget to change the default password . Now i am unable to login into the router after first log off but iam not able to recover password because the router don't have any external flash memory.

the other similar resolutions on the cisco/other website but none of them works for the Cisco 4506 switch I have.
1. Reboot
2. Press the "CTRL + C" button on the laptop to put the router into ROMMON mode.Result: Works fine and gets into the ROMMON 1 mode.
3. confreg 0x2142Result: This one does not work. confreg=0x2142 and that command is accepted by the switch but it does not tell us that we have to restart to make the changes. Now it goes ROMMON 2 mode.
4. resetResult: I type reset and the switches seems to be power cycled but it again goes to the password prompt which I dont know and this is the password that I am trying to recover or break.
I have a client whom uses a DSL 10 MG circuit as their backup circuit for Internet Connectivity in case of a failure. The circuit uses a DSL modem that is unreliable. I was recommending yesterday tot he client that perhaps we could place a Cisco router in place of the residential grade DSL modem /router currently in place.I wanted to place a 1900 ISR G2 in there, which would allow me to swap the DSL module out whenever I can talk the company into a Metro E connection. At that point I could swap the DSL module out and put an Ethernet module in to receive the Metro E. I was not able to find a solution last night using the Dynamic Configuration Tool. Seems DSL has been phased out.Is there any recommendation that could be made to accommodate this clients request for a Cisco router that will handle DSL?

Anything wrong with my config? port forwarding to my ssh wont work. Im using CISCO 1900 Series.
We have about 9 1900 routers and 1 ASA 5510 for partail mesh VPN network. So 8 1900 connect to 1 1900 and ASA located in HQ and datacenter. All worked well however there is one site running really strange. The tunnel between 1900 is up for a while and down. Reboot router seems to be the only fix. But tunnel to ASA does not seem to be down at all.
The issue happened again today, we rebooted the router on site but tunnel still not up. DEBUG shows: deleting SA reason "Death by retransmission P1 "
I can see alot of Apr 24 19:57:55.271: ISAKMP:(0): retransmitting phase 1 MM_NO_STATE...
To me it seems like the IDE packet sent but never got reply and timed out. I did also check on the other end, the HQ. All other tunnels are still running fine on that router, just this remote site. Plus I got the similiar output when debugging on HQ router.
One thing do notice though, there was no match on both router for the ACL to match/permit ESP traffic... I asked on-site staff to reboot the modem used in remote site.
i cant get access to my router IPX1900 after upgrade the last firmware version?

We have Cisco 1900 Series Integrated Services Routers (has a wired router and a wireless router) and since this morning we can not send emails.I inquired with both the ISP and the hosting provider and all settings are correct.I can receive emails from outside the router, but can't send any emails out.If I try to telnet mail902.opentransfer.com 25 it doesn't connect.Port 25 is the port we were using all the time and was working through the router.I connected my laptop directly to the modem and was able to send emails using port 25, also was able to telnet to outgoing mail server. I didn't change anything in the router.is there a way to "enable" port 25 or "enable" mail.homeserviceclub.com (smtp server) or mail902.opentransfer.com (hosting mail server) if this would solve the problem?I don't understand why is this happening as I never had to enable or disable any email ports or mail server addresses.

View 1 Replies View RelatedToday I was having a conversation with my Cisco Academy teacher from a few years back, and we couldn't figure this out.I am getting an internet connection via Verizon FiOS. Instead of giving me an ISR, they're going to just give me an ethernet cable. Here's what I want to do with it.
This cable is going to be plugged into a 1900 series router. Connect to that will be a 48 port switch. Connected to that will be multiple servers to be used for web hosting, email, databases, etc. My ISP is providing me with 13 public addresses, however, it is not my own unique subnet.
Here comes the question; how would I set this up? The way I was originally thinking was to assign one IP to fa0/0, a second to fa0/1, and then assign the fa0/1 address as the default gateways for all the hosts on the inside. But then I realized that it won't let me have the same network on 2 ports.
Sometimes our network lag and i thing there is a computer making this problem. i'd like to audit all input output of all port of a Catalyst 1900. all i manage to do is to enter to the console menu via Telnet.. once here, i try monitoring but i'm afraid to do a bad thing :

My customer is looking at using routers in DMVPN remote locations as DNS servers. He would like to be able to estimate how much memory the DNS cache will consume before going into production. I know you can get cache information when it's running, but he wants to plan ahead.I couldn't find any reports in Cisco or on the web of DNS caching causing memory issues, so I don't think he has much to worry about, but any rule of thumb as to how much memory each cache entry consumes would be useful. Or is there a protection mechanism to limit cache memory size in IOS ? The routers will be 877s and/or 1900-series.
View 0 Replies View RelatedI can see the console on the router. (Using the USB console connected to a Macintosh.) I was configuring the router though this console connection, and I created a new user (priv level 15) and removed the default 'cisco' user. So I'm stuck at the username/password login prompt now.
I decided to do the password recovery procedure (via the cisco doc I found etc), but I cannot break into ROMMON during the boot process. I'm not sure if that's because my Mac isn't sending the break, or what.
The pw recovery doc says you can "remove flash" if you can't break into the boot sequence. However, I cannot find any instructions on how to remove the flash. I've opened the router, and I see one very small daughter card on the main board that I think is the flash, but I'm not about to start arbitrarly prying parts off.
I need to find an iOS version that supports BGP, Dot1q, and MPLS for either a 1800 series or 1900 series not sure the best place to find this sort of info out.

View 3 Replies View RelatedI've got a problem with DHCP running on a cisco 1900 series router, 1921 to be precise. The Data VLAN works perfectly, i configured a ip helper address and its working. Problem tough is VLAN 20. This is the voice vlan. As u can see in the config below, this has been configured using VRRP and VRF for failover purposes. I did more of these configurations, and they all worked fine, just not with this particular router!
As u will notice i deleted all the not needed to know information or i X'ed it!

I'm a bit new to Cisco and i find this AAA a bit confusing..I've turend on AAA by:aaa new-model
Can I use this "default" list for WebVPN ? And what would be a different if i create new "sslvpn" list..Also when I'll be creating user for VPN remote access.. that user will also exist in local database and have access to router via SSH?Because the research I've done it doesn't seem you can group users in different "aaa groups" e.g. user admin belongs under "admin" aaa group which can do ssh to router, users for VPN can only do remote VPN access and not SSH and login into router.i saw ASA has some attribute for users called remote-user
•admin, in which users are allowed access to the configuration mode. This option also allows a user to connect via remote access.
•nas-prompt, in which users are allowed access to the EXEC mode.
•remote-access, in which users are allowed access to the network.
But i can't find this option in IOS on my 1900 Series ISR router.
We have been using a dhcp and tftp server to automatically configure branch WAN routers such as 1751's and 1841's for years but, have recently purchased a 1921 and 1941 as possible next generation replacements. The problem is when the 1900 series power up instead of getting a dhcp address directions to the tftp server it boots up and asks for the user name to be immediately changed or you will be "locked out". Any workaround to this so that I can again go back to download my common configuration? Or any other way of automatically configuring the newer version ios? Doing extra steps for 500 WAN branch routers is time consuming. Doing configurations without automation for that many is moving in the wrong direction.
