With the same hardware configuration as the Cisco PIX 525-UR, it delivers the ultimate in high
availability for a fraction of the price.
Failover Active/Active Software License
The Cisco PIX 525 Failover Active/Active (PIX 525-FO-AA) model is designed for use in
conjunction with a PIX 525-UR, providing a scalable Active/Active high-availability solution.
Advanced network topologies, such as those with asymmetric routing, are supported through the
Active/Active architecture where both Cisco PIX Security Appliances pass network traffic and
exchange bi-directional state sharing updates with one another. This license is supported by Cisco
PIX Security Appliance Software v7.0 and higher. License upgrades are available for existing PIX
525-FO units to convert from Active/Standby to Active/Active failover.
Feature Licenses
Security Context Licenses
The Cisco PIX 525 Security Appliance can support up to 50 security contexts, with each context
having its own separate security policies and administrative domain. Several tiers of security
context licenses are available for Cisco PIX 525 Security Appliances, including 5, 10, 20, and 50
security contexts. This license is supported by Cisco PIX Security Appliance Software v7.0 and
higher, and requires an Unrestricted (UR), Failover (FO), or Failover Active/Active (FO-AA) license,
security contexts are not supported on Restricted (R) models.
GTP Inspection License
The Cisco PIX 525 Security Appliance can provide advanced security services for GTP/GPRS 3G
Mobile Wireless environments upon installation of the GTP Inspection License. This license is
supported by Cisco PIX Security Appliance Software v7.0 and higher, and requires either an
Unrestricted (UR), Failover (FO), or Failover Active/Active (FO-AA) license, GTP inspection is not
supported on Restricted (R) models.
Encryption License
3DES/AES and DES Encryption Licenses
The Cisco PIX 525 Security Appliance has two optional encryption licenses, one license (PIX-VPN-
3DES) enables 168-bit 3DES and up to 256-bit AES encryption, the other license (PIX-VPN-DES)
enables 56-bit DES encryption. Both are available either at the time of ordering the Cisco PIX 525
Security Appliance, or can be obtained subsequently through Cisco.com. Note that an encryption
license must be installed to activate encryption services which are required before using certain
features including VPN and secure remote management.
