Re: C1941 Crypto is not enabled .

you need a security-license for that. Compare your router to the following output:

router#sh version | b Technology Package License Information

Technology Package License Information for Module:'c2900'


Technology    Technology-package           Technology-package

              Current       Type           Next reboot 


ipbase        ipbasek9      Permanent      ipbasek9

security      securityk9    Permanent      securityk9

uc            None          None           None

data          None          None           None

If you do not currently have the security license, and if you need the crypto capability, then yes you need to purchase the security license separately.

i have just purchased this router (Cisco 1941) , so how can i checked that whether we have security license or we have to buy .

1 - can you tell me the command to check the security license within the BOX. and if we have then how i can i enable this license .

2 - sh version out put will show the license file ?

Re: C1941 Crypto is not enabled .

the command to find the license is the "show version | b Technology" above. If you see the same "security"-line you have the license. If not, your reseller will be happy to sell you the license.
