Cisco ASA 5500 Series Configuration Guide using ASDM
Chapter 1 Introduction to the Cisco ASA 5500 Series
New Features
Phone Proxy addition to
Unified Communication
Wizard
The Unified Communications wizard guides you through the complete configuration and
automatically configures required aspects for the Phone Proxy. The wizard automatically
creates the necessary TLS proxy, then guides you through creating the Phone Proxy instance,
importing and installing the required certificates, and finally enables the SIP and SCCP
inspection for the Phone Proxy traffic automatically.
We modified the following screens:
Wizards > Unified Communications Wizard.
Configuration > Firewall > Unified Communications.
UC Protocol Inspection
Enhancements
SIP Inspection and SCCP Inspection are enhanced to support new features in the Unified
Communications Solutions; such as, SCCP v2.0 support, support for GETPORT messages in
SCCP Inspection, SDP field support in INVITE messages with SIP Inspection, and QSIG
tunneling over SIP. Additionally, the Cisco Intercompany Media Engine supports Cisco RT
Lite phones and third-party video endpoints (such as, Tandberg).
We did not modify any screens.
Inspection Features
DCERPC Enhancement DCERPC Inspection was enhanced to support inspection of RemoteCreateInstance RPC
messages.
We did not modify any screens.
Troubleshooting and Monitoring Features
SNMP traps and MIBs Supports the following additional keywords: connection-limit-reached, entity
cpu-temperature, cpu threshold rising, entity fan-failure, entity power-supply,
ikev2 stop | start, interface-threshold, memory-threshold, nat packet-discard, warmstart.
The entPhysicalTable reports entries for sensors, fans, power supplies, and related components.
Supports the following additional MIBs: ENTITY-SENSOR-MIB,
CISCO-ENTITY-SENSOR-EXT-MIB, CISCO-ENTITY-FRU-CONTROL-MIB,
CISCO-PROCESS-MIB, CISCO-ENHANCED-MEMPOOL-MIB,
CISCO-L4L7MODULE-RESOURCE-LIMIT-MIB, NAT-MIB, EVENT-MIB,
EXPRESSION-MIB
Supports the following additional traps: warmstart, cpmCPURisingThreshold,
mteTriggerFired, cirResourceLimitReached, natPacketDiscard,
ciscoEntSensorExtThresholdNotification.
We modified the following screen: Configuration > Device Management > Management
Access > SNMP.
TCP Ping Enhancement TCP ping allows users whose ICMP echo requests are blocked to check connectivity over TCP.
With the TCP ping enhancement you can specify a source IP address and a port and source
interface to send pings to a hostname or an IPv4 address.
We modified the following screen: Tools > Ping.
Show Top CPU Processes You can now monitor the processes that run on the CPU to obtain information related to the
percentage of the CPU used by any given process. You can also see information about the load
on the CPU, broken down per process, at 5 minutes, 1 minute, and 5 seconds prior to the log
time. Information is updated automatically every 5 seconds to provide real-time statistics, and
a refresh button in the pane allows a manual data refresh at any time.
We introduced the following screen: Monitoring > Properties > CPU - Per Process.
