Cisco Cisco ASA 5515-X Adaptive Security Appliance - No Payload Encryption

Cisco Intercompany Media 
Engine Proxy

Cisco Intercompany Media Engine (UC-IME) enables companies to interconnect on-demand, 
over the Internet with advanced features made available by VoIP technologies. Cisco 
Intercompany Media Engine allows for business-to-business federation between Cisco Unified 
Communications Manager clusters in different enterprises by utilizing peer-to-peer, security, 
and SIP protocols to create dynamic SIP trunks between businesses. A collection of enterprises 
work together to end up looking like one large business with inter-cluster trunks between them.

The following commands were modified or introduced: uc-ime, fallback hold-down, fallback 
monitoring, fallback sensitivity-file, mapping-service listening-interface, 
media-termination, ticket epoch, ucm address, clear configure uc-ime, debug uc-ime, 
show running-config uc-ime, inspect sip.

SIP Inspection Support for 
IME

SIP inspection has been enhance to support the new Cisco Intercompany Media Engine 
(UC-IME) Proxy. 

The following command was modified: inspect sip.

Time Stamps for Access List 
Hit Counts

Displays the timestamp, along with the hash value and hit count, for a specified access list.

The following command was modified: show access-list.

High Performance 
Monitoring for ASDM

You can now enable high performance monitoring for ASDM to show the top 200 hosts 
connected through the adaptive security appliance. Each entry of a host contains the IP address 
of the host and the number of connections initiated by the host, and is updated every 120 
seconds.

The following commands were introduced: hpm topn enable, clear configure hpm, show 
running-config hpm. 

Non-identical failover 
licenses

Failover licenses no longer need to be identical on each unit. The license used for both units is 
the combined license from the primary and secondary units.

For the ASA 5505 and 5510 adaptive security appliances, both units require the 
Security Plus license; the Base license does not support failover, so you cannot enable 
failover on a standby unit that only has the Base license.

The following commands were modified: show activation-key and show version.
