AHMED ALANSARI · ‎04-29-2013

Hi

I have have Cisco router VGW 3945 configured and connected to my CUCM and PSTN.

I want to upgrade IOS and backup my current configuration how is that?
If I upgrade IOS, will I lose my current configuration?
What is the latest firmware for 3945?

Thx

First of all, you need a support contract to download software updates.

In any case, seems to me that you are the end user with no experience in router maintenance. In that case the best choice would be to give the task to a reputable consultant, or certfied Cisco partner.

Hello Ahmed

For upgrade and backup config you have to use TFTP server for backup , find the below

router# copy running-conf tftp:

Address or name of remote host [ ]? 64.104.207.171 (IP of your TFTP)

Destination filename [ce_2-confg]? backup_cfg_for_my_router (name of backup file)

!!

1030 bytes copied in 2.489 secs (395 bytes/sec)

if you need to restore conf

outer#
copy tftp: running-config
Address or name of remote host []? 64.104.207.171   (ip of your router interface)
Source filename []? backup_cfg_for_my_router
Destination filename [running-config]?
Accessing tftp://10.66.64.10/backup_cfg_for_my_router...
Loading backup_cfg_for_router from 64.104.207.171 (via FastEthernet0/0): !
[OK - 1030 bytes]

1030 bytes copied in 9.612 secs (107 bytes/sec)

Hello

for your tftp prepration , you will open TFTP on your pc wo it will get the same IP of your PC. Your pc for (backup or upgrade ) should be connect to router using UTP cable between your PC network card and any interface fastethernet

of your router , kindly be informed that the PC and your router must have the same subnet and both are pingable.

Hello

for upgrade IOS , you have to find the size of your Image and calcuate if you have a space on your flash or not and if you do not have enough space which files will be removed , so be carefully/ Find below for that

r1#copy tftp flash

Address or name of remote host []? 10.50.50.100 IP of your tftp

Source filename []? c2800-i-mz.121-14.bin

Destination filename [c2800-i-mz.121-14.bin]?y

Accessing tftp://10.50.50.100/c2800-i-mz.121-14.bin...

Erase flash: before copying? [confirm]y

Erasing the flash filesystem will remove all files! Continue? [confirm]y

Erasing device... eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

eeeeeeeeee ...erased

Erase of flash: complete

Loading c2600-i-mz.121-14.bin from 10.10.10.2 (via Ethernet0/0):

Hi Ahmed,

In addition to great tips by Mr. Paolo and explaination by Mr. Kamal, after u download the IOS , u also verify the MD5 checksum by using FastSum utility before uploadong on router.

In case,if u do not have enough space on flash: , do keep backup of existing IOS.

Further, u can also take the backup of your startup config in similar fashion [copy nvram:startup config tftp:]

What is the existing IOS version u are using and which version u want to upgarde to ?

regds,

aman
