Depending upon on the service type, it will either be associated with TCP or UDP port.
The Cisco VPN client is the client side application used to encrypt traffic from an end user's computer to the company network. IPSec is used to encrypt the traffic. When using standard IPSec, IKE is used for the key negotiation and IPSec to encrypt the data. IKE uses UDP port 500 and IPSec uses IP protocol 50, assuming ESP is used.
