Cisco ASA 5510 Adaptive Security Appliance Security Plus License Businesses can significantly extend the capabilities of the Cisco ASA 5510 by purchasing and installing a Security Plus license. This license increases port density on the platform by enabling the fourth Fast Ethernet port and removing the restriction on the out-of-band management port so that it can be repurposed to a general traffic port, if desired. Integration into switched network environments is simplified with this license, as support for up to 10 VLANs is enabled. Furthermore, this upgrade license maximizes business continuity by enabling Active/Standby high-availability services and triples VPN capacity by supporting up to 150 concurrent VPN connections from mobile users, remote sites, and business partners.
