Hi Sandhya,
please send an e-mail to
ask-axp-pm@cisco.com to get an authorization key. Provide the expiration information and basic information such as your company name, service module equipment you are using along with the certificate number. This number is most easily found in the file name of the tar file you originally recieved. For example, in file AXP_cert_10695.tar the certificate number is 10695.
Thanks,
Raghavendra
