Usage Guidelines
The flow keyword lets you determine, for any flow that you can describe, the policies that the security appliance would apply to that flow. You can use this to check that your service policy configuration will provide the services you want for specific connections. The arguments and keywords following the flow keyword specifies the flow in ip-5-tuple format with no object grouping.
Because the flow is described in ip-5-tuple format, not all match criteria are supported. Following are the list of match criteria that are supported for flow match:
•
match access-list
•
match port
•
match rtp
•
match default-inspection-traffic
The priority keyword is used to display the aggregate counter values of packets transmitted through an interface.
The number of embryonic connections displayed in the show service-policy command output indicates the current number of embryonic connections to an interface for traffic matching that defined by the class-map command. The embryonic-conn-max
field shows the maximum embryonic limit configured for the traffic class using the Modular Policy Framework. If the current embryonic connections displayed equals or exceeds the maximum, TCP intercept is applied to new TCP connections that match the traffic type defined by the class-map command.

Usage Guidelines
You can use the vertical bar | to filter the display. Type | for more display filtering options.
The show pdp-context command displays PDP context-related information.
The Packet Data Protocol context is identified by the tunnel ID, which is a combination of IMSI and NSAPI. A GTP tunnel is defined by two associated PDP Contexts in different GSN nodes and is identified with a Tunnel ID. A GTP tunnel is necessary to forward packets between an external packet data network and a mobile station user.
The show gtp requests command displays current requests in the request queue.
Examples
The following is sample output from the show gtp requests command:
hostname# show gtp requests
0 in use, 0 most used, 200 maximum allowed
You can use the vertical bar | to filter the display, as in the following example:
hostname# show service-policy gtp statistics | grep gsn
This example shows the GTP statistics with the word gsn in the output.

Usage Guidelines
The show sip command assists in troubleshooting SIP inspection engine issues and is described with the inspect protocol sip udp 5060 command. The show timeout sip command displays the timeout value of the designated protocol.
The show sip command displays information for SIP sessions established across the security appliance. Along with the debug sip and show local-host commands, this command is used for troubleshooting SIP inspection engine issues.
Note
We recommend that you configure the pager command before using the show sip command. If there are a lot of SIP session records and the pager command is not configured, it will take a while for the show sip command output to reach its end.
Examples
The following is sample output from the show sip command:
call-id c3943000-960ca-2e43-228f@10.130.56.44
| state Call init, idle 0:00:01
call-id c3943000-860ca-7e1f-11f7@10.130.56.45
| state Active, idle 0:00:06
This sample shows two active SIP sessions on the security appliance (as shown in the Total
field). Each call-id
represents a call.
The first session, with the call-id
c3943000-960ca-2e43-228f@10.130.56.44, is in the state Call Init
,
which means the session is still in call setup. Call setup is complete only when the ACK is seen. This session has been idle for 1 second.
The second session is in the state Active
, in which call setup is complete and the endpoints are exchanging media. This session has been idle for 6 seconds.

Usage Guidelines
The show skinny command assists in troubleshooting SCCP (Skinny) inspection engine issues.
Examples
The following is sample output from the show skinny command under the following conditions. There are two active Skinny sessions set up across the security appliance. The first one is established between an internal Cisco IP Phone at local address 10.0.0.11 and an external Cisco CallManager at 172.18.1.33. TCP port 2000 is the CallManager. The second one is established between another internal Cisco IP Phone at local address 10.0.0.22 and the same Cisco CallManager.
---------------------------------------------------------------
1 10.0.0.11/52238 172.18.1.33/2000 1
MEDIA 10.0.0.11/22948 172.18.1.22/20798
2 10.0.0.22/52232 172.18.1.33/2000 1
MEDIA 10.0.0.22/20798 172.18.1.11/22948
The output indicates a call has been established between both internal Cisco IP Phones. The RTP listening ports of the first and second phones are UDP 22948 and 20798 respectively.
The following is the xlate information for these Skinny connections:

Usage Guidelines
The SID is a unique number that identifies the SSH session. The Client IP is the IP address of the system running an SSH client. The Version is the protocol version number that the SSH client supports. If the SSH only supports SSH version 1, then the Version column displays 1.5. If the SSH client supports both SSH version 1 and SSH version 2, then the Version column displays 1.99. If the SSH client only supports SSH version 2, then the Version column displays 2.0. The Encryption column shows the type of encryption that the SSH client is using. The State column shows the progress that the client is making as it interacts with the security appliance. The Username column lists the login username that has been authenticated for the session.
Examples
The following example demonstrates the output of the show ssh sessions command:
hostname# show ssh sessions

Usage Guidelines
The show traffic command lists the number of packets and bytes moving through through each interface since the last show traffic command was entered or since the security appliance came online. The number of seconds is the duration the security appliance has been online since the last reboot, unless the clear traffic command was entered since the last reboot. If this is the case, then the number of seconds is the duration since that command was entered.
Examples
The following example shows output from the show traffic command:
outside:
received (in 102.080 secs):
2048 packets 204295 bytes
20 pkts/sec 2001 bytes/sec

Usage Guidelines
The show uauth command displays the AAA authorization and authentication caches for one user or for all users.
This command is used with the timeout command.
Each user host IP address has an authorization cache attached to it. The cache allows up to 16 address and service pairs for each user host. If the user attempts to access a service that has been cached from the correct host, the security appliance considers it preauthorized and immediately proxies the connection. Once you are authorized to access a website, for example, the authorization server is not contacted for each image as it is loaded (assuming the images come from the same IP address). This process significantly increases performance and reduces the load on the authorization server.
The output from the show uauth command displays the username that is provided to the authorization server for authentication and authorization purposes, the IP address to which the username is bound, and whether the user is authenticated only or has cached services.
Note
When you enable Xauth, an entry is added to the uauth table (as shown by the show uauth command) for the IP address that is assigned to the client. However, when using Xauth with the Easy VPN Remote feature in Network Extension Mode, the IPSec tunnel is created from network to network, so that the users behind the firewall cannot be associated with a single IP address. For this reason, a uauth entry cannot be created upon completion of Xauth. If AAA authorization or accounting services are required, you can enable the AAA authentication proxy to authenticate users behind the firewall. For more information on AAA authentication proxies, see to the aaa commands.
Use the timeout uauth command to specify how long the cache should be kept after the user connections become idle. Use the clear uauth command to delete all the authorization caches for all the users, which will cause them to have to reauthenticate the next time that they create a connection.
Examples
This example shows sample output from the show uauth command when no users are authenticated and one user authentication is in progress:
hostname(config)# show uauth
This example shows sample output from the show uauth command when three users are authenticated and authorized to use services through the security appliance:
hostname(config)# show uauth
user `pat' from 209.165.201.2 authenticated
user `robin' from 209.165.201.4 authorized to:
port 192.168.67.34/telnet 192.168.67.11/http 192.168.67.33/tcp/8001
192.168.67.56/tcp/25 192.168.67.42/ftp

Usage Guidelines
The show version command allows you to display the software version, operating time since the last reboot, processor type, Flash partition type, interface boards, serial number (BIOS ID), activation key value, license type (R or UR), and time stamp for when the configuration was last modified.
The serial number listed with the show version command is for the Flash partition BIOS. This number is different from the serial number on the chassis. When you get a software upgrade, you will need the serial number that appears in the show version command, not the chassis number.
Note
The uptime value indicates how long a failover set has been running. If one unit stops running, the uptime value will continue to increase as long as the other unit continues to operate.
Examples
The following example shows how to display the software version, hardware configuration, license key, and related uptime information:

Usage Guidelines
Use the show webvpn csd command to check the operational status of CSD. The CLI responds with one of the following messages when you enter this command:
•
0 SNMP packets input
CSD is in the running configuration, but it is disabled. Go to webvpn configuration mode and enter the csd enable command to enable CSD.
•
0 Bad SNMP version errors
n.n.n.n is currently installed and enabled.
CSD is enabled. The distribution package read from the flash device determines the version number. You can access Cisco Secure Desktop Manager through the ASDM Configuration > CSD menu path. CSD is accessible to users only if the CSD configuration contains a location.
Use the show webvpn csd image command to test a file to see if it is a valid CSD distribution package. Similarly, the csd image command, when entered in webvpn configuration mode, installs CSD only if the file you name in the command is a valid CSD distribution package. Otherwise, it displays an "ERROR: Unable to use CSD image" message.
The show webvpn csd image command tests a file to see if it is a valid CSD distribution package without installing CSD automatically if the file is valid. The CLI responds with one of the following messages when you enter this command:
•
0 Unknown community name
Make sure the filename is in the form the form securedesktop_asa_<n>_<n>*.pkg. If it is, replace the file with a fresh one obtained from the following website:
http://www.cisco.com/cisco/software/navigator.html
Then reenter the show webvpn csd image command. If the image is valid, use the csd image and csd enable commands in webvpn configuration mode to install and enable CSD.
•
This is a valid Cisco Secure Desktop image:
Version : 3.1.0.25
Built on : Wed 10/19/2005 14:51:23.82
Note that the CLI provides both the version and date stamp if the file is valid.
Examples
The following example indicates CSD is installed in the running configuration and enabled:
hostname# show webvpn csd
Secure Desktop version 3.1.0.25 is currently installed and enabled.
The following example shows the file specified is a valid CSD image:
hostname#show webvpn csd image securedesktop_asa_3_1_0_25.pkg
This is a valid Cisco Secure Desktop image:
