Chapter 3 Monitoring and Backing Up the BTS
Log Archive Facility (LAF)
The steps to set up the authorization in external archive server and turn the LAF processes to active is
listed below:
Setup Non-Interactive SSH Login to External Archive Server
Note The external archive system is recommended to be located such that it can be accessed by the
management network. In such a case, the static routes in the CA system should be explicitly set so that
the traffic to the external archive system is routed through the management network see section (“Adding
Static Routes” section for more details). Otherwise, the traffic is routed through the default network (i.e.
signaling network) and may not be able to reach the external archive system.
Step 1 Log in to the Cisco BTS 10200 primary EMS as root.
Step 2 From the EMS, login to the external archive server via ssh to get the external archive server added to the
/.ssh/known_hosts file.
Step 3 Log off from the external archive server.
Step 4 While still logged in on the primary EMS as root, generate an SSH key.
a. Execute cd /opt/BTSossh/bin.
b. Execute ssh-keygen -t rsa.
c. Press Enter to accept the default file name for the key (/.ssh/id_rsa).
d. Enter y if prompted to choose whether to overwrite the existing file.
e. Press Enter when prompted to enter a passphrase (i.e. no passphrase).
f. Transfer the resulting file (/.ssh/id_rsa.pub) to a temporary location on the external archive server.
Step 5 Set up the external archive server with the key generated in Step 4.
a. Login to the external archive system as root.
b. If a /.ssh/authorized_keys file does not exist on the external archive system, rename the id_rsa.pub
file (copied from the Cisco BTS 10200 EMS) to /.ssh/authorized_keys. If the file does exist, append
the id_rsa.pub file to it.
Step 6 On the primary EMS, execute
ssh root@abcd
where abcd is the IP address or fully-qualified domain name of the external archive server.
Step 7 Verify that login to the external archive server is successful and that no prompts for username or
password are issued.
Step 8 Run enableLAF in EMS platform directories (i.e. /opt/ems/bin and /opt/bdms/bin)
Step 9 Repeat Steps 1-8 for the secondary EMS, primary CA and secondary CA. (In CA, the platform
directories are /opt/OptiCall/CAxxx/bin, /opt/OptiCall/FSPTCyyy/bin, /opt/OptiCall/FSAINzzz/bin).
Note Billing has a similar mechanism/steps to SFTP their Call Detail Blocks (CDB) files to an external
machine. If the LAF and Billing use the same target machine, then in both EMS, perform Steps 1-7 only
once. You must still run Step 8 to enable LAF. And you must still run Steps 1 -9 in CA nodes.
