Table C-1 Cisco Security Appliance Debugging Command
To	Use the Command	Notes
Show ICMP packet information for pings to the Cisco Adaptive Security Appliance interfaces	debug icmp trace	We strongly recommend that you disable debug messages once you have completed your troubleshooting. To disable ICMP debug messages, use the no debug icmp trace command.
Show messages relating to the certificate validation between Cisco Unified Presence/Cisco Adaptive Security Appliance or Cisco Adaptive Security Appliance/foreign domain	debug crypto ca	You can increase log level on ASA by adding the log level parameter to this command, for example: debug crypto ca 3
	debug crypto ca messages	Shows only debug messages for input and output messages
	debug crypto ca transactions	Shows only debug messages for transactions
Show the SIP messages sent through Cisco Adaptive Security Appliance	debug sip
Send log messages to a buffer (for later viewing)	terminal monitor
Enable system log messages	logging on	We strongly recommend that you disable system log messages once you have completed your troubleshooting. To disable system log messages, use the no logging on command.
Send system log messages to a buffer	logging buffer debug
Set system log messages to be sent to Telnet or SSH sessions	logging monitor debug
Designate a (syslog) server to receive the system log messages	logging host <interface_name> <ip_ address>	•The interface_name argument specifies the Cisco Adaptive Security Appliance interface through which you access the syslog server. •The ip_address argument specifies the IP address of the syslog server.
Ping the Interfaces	ping	Refer to the Troubleshooting section of the Cisco Security Appliance Command Line Configuration Guide for details on pinging the Cisco Adaptive Security Appliance interfaces, and also pinging between hosts on different interfaces to ensure that the traffic can pass successfully through the Cisco Adaptive Security Appliance. You can also ping an interface in ASDM by selecting Tools > Ping. Note You will not be able to ping the public Cisco Unified Presence IP address. However the MAC address of the ASA outside interface should appear in the ARP table (arp -a).
Trace the route of a packet	traceroute	You can also trace the route of a packet in ASDM via Tools > Traceroute.
Trace the life span of a packet through the Cisco Adaptive Security Appliance	packet-tracer	You can also trace the life span of a packet in ASDM via Tools > Packet Tracer.

Capturing the Output on the Internal and External Interfaces

Procedure

Step 1 Enter config mode:

>Enable

>password

>config t

Step 2 Define an access-list to specify the traffic to be captured, for example:

access-list cap extended permit ip 10.53.0.0 255.255.0.0 10.53.0.0 255.255.0.0

Step 3 It is recommended that you clear the capture content before starting the tests. Use the command "clear capture in" to clear the internal interface capture, and the command "clear capture out" to clear the external interface capture.

Step 4 Enter this command to capture the packets on the internal interface:

cap in interface inside access-list cap

Step 5 Enter this command to capture the packets on the external interface:

cap out interface outside access-list cap

Step 6 Enter this command to capture TLS specific packets:

capture <capture_name> type tls-proxy interface <interface_name>

Step 7 Enter this command to retrieve the packet capture:

copy /pcap capture:in tftp://xx.xx.xx.xx

copy /pcap capture:out tftp://xx.xx.xx.xx

Enter this command to copy the output to disk and retrieve using ASDM (Actions > File Management > File Transfer):

copy /pcap capture:in disk0:in_1

TLS Proxy Debugging Commands

Table C-2 lists the debugging commands for the TLS Proxy.

Table C-2 TLS Proxy Debugging Commands
To	Use the Command(s)
Enable TLS proxy-related debug and syslog output	debug inspect tls-proxy events debug inspect tls-proxy errors debug inspect tls-proxy all
Show a TLS proxy session output	show log
Check the active TLS proxy sessions	show tls-proxy
View the detail of the current TLS proxy sessions (Use when Cisco Adaptive Security Appliance successfully establishes connections with Cisco Unified Presence and the foreign domain)	show tls-proxy session detail

Debugging Access Edge and OCS Server

•Initiating a Debug Session on OCS/Access Edge

•Verifying the DNS Configuration on Access Edge

Initiating a Debug Session on OCS/Access Edge

Procedure

Step 1 Select Start > Administrative Tools > Computer Management on the external Access Edge server.

Step 2 Right-click Microsoft Office Communications Server 2007 in the left pane.

Step 3 Select Logging Tool > New Debug Session.

Step 4 Select SIP Stack in the Logging Options.

Step 5 Select All for the Level value.

Step 6 Select Start Logging.

Step 7 Select Stop Logging when complete.

Step 8 Select Analyze Log Files.

Verifying the DNS Configuration on Access Edge

Procedure

Step 1 On the external Access Edge server, select Start > Administrative Tools > Computer Management.

Step 2 Right-click on Microsoft Office Communications Server 2007in the left pane.

Step 3 Select the Block tab.

Step 4 Check that the domain not blocked.

Step 5 Ensure that the following options are selected in the Access Methods pane:

•Federate with other domains

•Allow discovery of federation partners

Step 6 Check the Access Edge is publishing DNS SRV records.
