Cisco Infrastructure :: 2811c Router - Change IOS Image?
Nov 4, 2012
last month I bought in our China office a 2811c router.I asked (to a Chinese informatic company) a router to create a IPSEC - site to site VPN connection with an ASA.I'm not in China, and when they told me that router was power on, I tried to configure VPN.It was a bomb when I found that the image installed was "c2800nmc-spservicesk9-mz.150-1.M7.bin" not enough for my VPN, we need for example "c2800nmc-advipservicesk9-mz.150-1.M7.bin".Is it possible that in China this image is forbidden for VPN political restriction? - If I can, what's the Cisco procedure to change ios image? I must to buy an advanced license or I only register and download which image I need?

My customer has purchased the standard Cisco 881 (Data) ISR router and now requires (Voice) CUBE services for the support of IP-IP gateway SIP services. I noticed there is multiple models for the Cisco 881 such as the SEC/3G & SRST. Any way to change the Universal image from Data to Voice to support CUBE if possible. Just want to try and eliminate purchasing new Cisco 881 with Universal image for Voice.

I am wondering how to change which image is loaded by default on an ASA5510. I have two image files stored in the flash memory on disk0:/ but need to change which one is loaded on boot. I used the command "boot system disk0:/asa722-12-k8.bin" which completed successfully, but when the system starts it says two images exist and the default is 1, loading the previous file. Is there a command to change the order that is used?

End user have had problem with IP phones that are connected to 3750 stack; many times IP phones lose connection with CallManager and the only way to clear this issue is with clear arp command. DHCP for IP phones is configured in 3750 stack.
At the beginning 3750 stack was set a VTP server, and the others as VTP clients, we detected another VTP server switch so we thought that was the problem, but after removing the issue remains. Finally we set all switch in transparent mode.
Base on this we decided to change the software image 12.2(35)SE1 C3750-ADVIPSERVICESK ---> 122-53.SE2 IPSERVICES I'm going to follow the procedure 3750 Series Switch Stack IOS Upgrade − Automatic .
as it show in the following information there are 4 differents models of 3750 switches, I have already download c3750-ipservicesk9-tar.122-53.SE2.tar for 3750G-24TS.
I have two doubts:
1. There is no problem for using this tar file for all models?
2. I followig command is correct for the change I plann to do ?
Switch#archive download-sw /allow-feature-upgrade /overwrite tftp://192.168.0.24/c3750-ipservicesk9-tar.122-53.SE2.tar
#sh inventoryNAME: "1", DESCR: "WS-C3750G-24TS" 16MB Flash 128 DRAMPID: WS-C3750G-24TS-E

when I was using image 1.0.0.27, I was able to move the management VLAN from 1 to which ever VLAN I wanted. For some reason, after switching the image to 1.1.1.8, I no longer have that function.

I'm looking at adding a Cisco 3750-X switch running c3750e-universalk9-mz.122-55.SE1 (IP base license) into a stack of 3750-G switches running c3750-ipbasek9-mz.122-55.SE1.bin Given that the version and feature sets are the same I don't forsee any compatibility issues. Would there be any reason why a universal image wouldn't stack correctly with other switches running the single .bin file?

I've got a 2621XM that has not been used for a while.Completely stripped of any modules and configuration files, the router will continually cycle the startup process without actually booting from the IOS.
The cycle displays the following :
System Bootstrap, Version 12.2(8r) [cmong 8r], RELEASE SOFTWARE (fc1)
Copyright (c) 2003 by cisco Systems, Inc.
program load complete, entry point: 0x80008000, size: 0x10034ec
What I've tried:
1) Downloading another IOS image (c2600-is-mz.123-20.bin) via Xmodem and running "confreg 0x2102" from the rommon. All that did is change the last message to "program load complete, entry point: 0x80008000, size: 0x10fa95c"
2) Running the command "boot flash:c2600-is-mz.123-20.bin". If I enable the diagnostics via rommon, the cycle expands to:
System Bootstrap, Version 12.2(8r) [cmong 8r], RELEASE SOFTWARE (fc1)
Copyright (c) 2003 by cisco Systems, Inc.
program load complete, entry point: 0x80008000, size: 0x10fa95c
Testing lower main memory - data equals address
Testing lower main memory - checkerboard
[code]....
If it wasn't for the lack of error messages, I would assume it was a hardware issue.If the image was corrupted, I would expect a message indicating that the image couldn't be read.

imagine IOS image required size lists:DRAM 256 / 64 Flash
Then show ver on my router 3825 lists the below. Technically speaking the below should have the 64M flash required right? Why again it shows as 62592K and not 64000K?

I recently formatted the flash drive of an 1800 router and replaced it with an updated image. However, the new features within the new image aren't reflected in the router. I believe that this is because a reboot would be required for the updates in the new image to be reflected in the router i.e. the image needs to be added to the system. How to get the image to the system without a reboot and if by doing so I would get all the new features from the image.For example, the show version below shows the old image in the system as [code]

Customer has ordered the following routers, which will go in three separate locations.
1. 3945 W/SPE150, IP Base Image
2. 3945 Voice Bundle, includes PVDM3-64 and (1) 2-port T1 MFT
3. 2911 IP Base Image.
If the customer wants to move the Voice image from the existing 3945 to the 3945/WSPE150, would he just need to contact Cisco Licensing, or would the customer have to pay for a software upgrade on the 3945/WSPE150?
Same scenario, except moving the Voice Image to the 2911 router.

whether a Cisco Router 2911 would work on images other than universal image. This is the question raised by one of our customer. He has 2811 Router where-in he has configured T1/E1 configuration, terminated to Zyxel Modem and working fine. Now he wants to replace this 2811 router with 2911 router. Since the universal image in 2911 router is not working with the present configuration in 2811 router, he wants to know, what options are there for him to configure this in 2911.

I had originally set up my E1200 Jan 2012 & had Cisco Connect setup. I didn't use it much but back in Oct after being away for 10 days I didn't have internet connection. Had to re-set both cable modem--then I at least had connection via ethernet, but still no wifi connection. Had to turn off for awhile to get it Router to properly reset & work. & then I think I had to do another reset maybe in Dec, can't remember exactly.
As I mention in another post, I have been having frequent intermittent not connected to internet messages for a long time. Usually if I just turn wifi off & then turn it back on it finds my network (although frequently I notice that it was on my guest network rather than main). I still don't know if it is cable modem, router or my ISP, altho they came out & checked & said signals ok, but modem could be going (Its old but about to move so don't want to buy new modem now).
I updated to Mountain Lion about 2-3 weeks ago.After a Panic last night I was advised to make sure everything updated including router firmware.When I opened Cisco Connect it said I had an unsupported Operating System. Trying to figure this all out, I finally found links to download Cisco Connect that are supposed to be compatible w Mountain Lion (at least the original link said that, but not where I went w the links so hoping it is right link for that). Anyway I downloaded it & was reading a bit & then clicket on the setup icon.
That said it was damaged & to eject it. I downloaded it via wifi just like I download other software. Maybe it is hyper sensitive so I need to take it over to plug directly into my cable modem? But then that will mess up the router, although I guess it will need to be reset any way.So I think i need to get Cisco Connect updated so it works w Mountain Lion. Mountain Lion told me about 1 software that wasn't compatible but didn't pick up on Cisco Connect.So don't know if I need to do a hard wired download, unlike the way I download other things, or what to get an undamaged copy. I then hope that it will see the old version, even though it isn't didn't work & hopefully pick up all my settings & all.
& then I guess I still need to check for a firmware update. & I understand that a firmware update should be done w a good connection (although the user manual just says good signal, web says hard wired ethernet. & because of the intermittent issues I plan to to it manually by 1st downloading & then installing from the download so there won't be a risk of interruption during install--if its even needed.

Are the IOS commands the same on a router and a ASA for these two topics....CBT Nuggets where I train has 553 videos for some of the new topics. I am preparing for 554 as it has more ASA focus and thats more interesting to me.

I recently obtained a 2851 and have been battling this issue for a week now. An odd set of circumstances happen with the bootstrap startup process. If the router has loss of power or when reloaded; it fails to read the CF card and boots to rommon. I can tftp an image to it (tftpdnld -r) and IOS CAN read the flash card along with any saved configuration.In fact once in IOS, I can wr mem and print the hardware details of the CF card. Once I reload the router it goes to rommon, fails to open the flash, then sits until i tftp the image back. When the router load IOS, it also loads the startup config.I don't think it's a problem with the CF card as IOS can read it. I've tried formatting the card from IOS and from my pc as FAT, FAT16, FAT32, and NTFS - it didn't make a different. I updated the ROMMON to allow for USB booting but haven't purchased a USB Drive yet for testing. The upgrade didn't resolve this issue either. It almost seems like a firmware problem with the EPROM.

We are having problems configuring NAT on our Cisco 1921 Router. Below is the running config. The problem we're having is for example our FTP server 192.168.1.16, cannot be accessed from its outside IP address, which is NATed on the router. The server is verified to be up and running and when we do a show debug ip nat, we see the router is translating outside users attempting to access the ftp server to it's correct internal IP address.

Suppose a broadcasted IP packet reaches one of the integrated RJ-45 ports on a 2911 ISR G2, will it be possible to configure the router so that the other integrated RJ-45 ports, ESM/EHWIC modules installed on the router, as well as the MGF also recieve the packet? Technically, the router should act similar to a switch with the SRE behaving similar to a seperate machine connected via the MGF and other external machine connected to the ports of the router to recieve the broadcasted packet.
Also, if SNMP traps were generated from the router,Will it be possible to send the traps from the router via the MGF to the SRE installed on the router?

I have the following network connected and configured to a single Cisco 1800 router.
VLAN 2 (10.1.20.0/24)
|
int vlan2, ip address 10.1.20.1
|
Cisco 1800 ----- int fa0, public ip address ---- Internet
|
int vlan3, ip address 10.1.30.1
|
VLAN 3 (10.1.30.0/24)
VLAN 2 is server vlan with a webserver.
VLAN 3 is clients.
NAT configuration:
VLAN 2 and VLAN 3 is using NAT to access the internet, and both is configured as inside interfaces.fa0 is configured as outside interface. Now I don't know if this is about NAT, but I've tried several things without luck.
Problem:
A client in VLAN 3 tries to access a domain on the webserver in VLAN 2.It starts by sending a DNS query to a DNS server located at the ISP, and gets the ip address for the domain, which is of course a public ip address. Then nothing happens because the client tries to access the domain on the webserver using the public ip address, and the webserver have a local ip address 10.1.20.20 which is on the local LAN (VLAN 2).
I've tried NAT because I have to change the destination ip address, but I can't seem to get it right.

Is there a way to be able to check from one computer on a network to another computer on the same network when both have been set up with NAT?
For example, computer 10.0.0.10 cannot ping 10.0.0.20 because NAT has been set up. Port forwarding does not seem to be an answer. Is it possible for NATted computers to be able to ping each other or not?
