Chapter1 Introduction to the Cisco ASA 5500 Series
New Features
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 commands.
Inspection Features
DCERPC Enhancement DCERPC Inspection was enhanced to support inspection of RemoteCreateInstance RPC
messages.
We did not modify an commands.
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,
ikev2stop | 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 introduced or modified the following commands: snmp cpu threshold rising, snmp
interface threshold, snmp-server enable traps.
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 command: ping tcp.
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 command: show process cpu-usage sorted.
