Adding and removing virtual IP addresses and ports for CP servers at run-time

The procedure of adding and removing virtual IP addresses and ports for CP servers at run-time is only applicable for communication over Veritas Product Authentication Services (AT) and for non-secure communication. It does not apply for communication over HTTPS.

You can use more than one virtual IP address for coordination point server (CP server) communication. You can assign port numbers to each of the virtual IP addresses.

You can use the cpsadm command if you want to add or remove virtual IP addresses and ports after your initial CP server setup. However, these virtual IP addresses and ports that you add or remove does not change the vxcps.conf file. So, these changes do not persist across CP server restarts.

See the cpsadm(1m) manual page for more details.

To add and remove virtual IP addresses and ports for CP servers at run-time

To list all the ports that the CP server is configured to listen on, run the following command:
```
# cpsadm -s cp_server -a list_ports
```
If the CP server has not been able to successfully listen on a given port at least once, then the Connect History in the output shows never. If the IP addresses are down when the vxcpserv process starts, vxcpserv binds to the IP addresses when the addresses come up later. For example:
```
# cpsadm -s 127.0.0.1 -a list_ports

IP Address                     Connect History
[10.209.79.60]:14250           once
[10.209.79.61]:56789           once
[10.209.78.252]:14250          never
[192.10.10.32]:14250           once
```
CP server does not actively monitor port health. If the CP server successfully listens on any IP:port at least once, then the Connect History for that IP:port shows once even if the port goes down later during CP server's lifetime. You can obtain the latest status of the IP address from the corresponding IP resource state that is configured under VCS.

To add a new port (IP:port) for the CP server without restarting the CP server, run the following command:

# cpsadm -s cp_server -a add_port 
-i ip_address -r port_number

For example:

# cpsadm -s 127.0.0.1 -a add_port -i 10.209.78.52 -r 14250
Port [10.209.78.52]:14250 successfully added.

To stop the CP server from listening on a port (IP:port) without restarting the CP server, run the following command:

# cpsadm -s cp_server -a rm_port 
-i ip_address -r port_number

For example:

# cpsadm -s 10.209.78.52 -a rm_port -i 10.209.78.252
No port specified. Assuming default port i.e 14250
Port [10.209.78.252]:14250 successfully removed.
