The command output was expanded to include a warning message for users who try to configure an IKE encryption method that the hardware does not support.


Examples

The following is sample output from the show crypto isakmp policy command, after two IKE policies have been configured (with priorities 15 and 20, respectively):

Router# show crypto isakmp policy

Protection suite priority 15
        encryption algorithm:    DES - Data Encryption Standard (56 bit keys)
        hash algorithm:  Message Digest 5
        authentication method:   Rivest-Shamir-Adleman Signature
        Diffie-Hellman Group:    #2 (1024 bit)
        lifetime:      5000 seconds, no volume limit
Protection suite priority 20
        encryption algorithm:    DES - Data Encryption Standard (56 bit keys)
        hash algorithm: Secure Hash Standard
        authentication method:   preshared Key
        Diffie-Hellman Group:    #1 (768 bit)
        lifetime:      10000 seconds, no volume limit
Default protection suite
        encryption algorithm:    DES - Data Encryption Standard (56 bit keys)
        hash algorithm: Secure Hash Standard
        authentication method:   Rivest-Shamir-Adleman Signature
        Diffie-Hellman Group:    #1 (768 bit)

Table 44 through Table 47 show the various states that may be displayed in the output of the show crypto isakmp sa command. When an Internet Security Association and Key Management Protocol (ISAKMP) SA exists, it will most likely be in its quiescent state (QM_IDLE). For long exchanges, some of the MM_xxx states may be observed.

Table 44 States in Main Mode Exchange

State
Explanation

MM_NO_STATE

The ISAKMP SA has been created, but nothing else has happened yet. It is "larval" at this stage—there is no state.

MM_SA_SETUP

The peers have agreed on parameters for the ISAKMP SA.

MM_KEY_EXCH

The peers have exchanged Diffie-Hellman public keys and have generated a shared secret. The ISAKMP SA remains unauthenticated.

MM_KEY_AUTH

The ISAKMP SA has been authenticated. If the router initiated this exchange, this state transitions immediately to QM_IDLE, and a Quick Mode exchange begins.


Table 45 States in Aggressive Mode Exchange 

State
Explanation

AG_NO_STATE

The ISAKMP SA has been created, but nothing else has happened yet. It is "larval" at this stage—there is no state.

AG_INIT_EXCH

The peers have done the first exchange in aggressive mode, but the SA is not authenticated.

AG_AUTH

The ISAKMP SA has been authenticated. If the router initiated this exchange, this state transitions immediately to QM_IDLE, and a quick mode exchange begins.


Table 46 States in Quick Mode Exchange

State
Explanation

QM_IDLE

The ISAKMP SA is idle. It remains authenticated with its peer and may be used for subsequent quick mode exchanges. It is in a quiescent state.


Table 47 show crypto isakmp sa Field Descriptions

Field
Description

f_vrf/i_vrf

The front door virtual routing and forwarding (FVRF) and the inside VRF (IVRF) of the IKE SA. If the FVRF is global, the output shows f_vrf as an empty field.

show crypto key pubkey-chain rsa

To display the RSA public keys of the peer that are stored on your router, use the show crypto key pubkey-chain rsa command in EXEC mode.

show crypto key pubkey-chain rsa [name key-name | address key-address]

Syntax Description

name key-name

(Optional) The name of a particular public key to view.

address key-address

(Optional) The address of a particular public key to view.


Command Modes

EXEC

Command History

Release
Modification

11.3 T

This command was introduced.


Usage Guidelines

This command shows RSA public keys stored on your router. This includes peers' RSA public keys manually configured at your router and keys received by your router via other means (such as by a certificate, if certification authority support is configured).

If a router reboots, any public key derived by certificates will be lost. This is because the router will ask for certificates again, at which time the public key will be derived again.

Use the name or address keywords to display details about a particular RSA public key stored on your router.

If no keywords are used, this command displays a list of all RSA public keys stored on your router.

Examples

The following is sample output from the show crypto key pubkey-chain rsa command:

Router# show crypto key pubkey-chain rsa

Codes: M - Manually Configured, C - Extracted from certificate

Code  Usage        IP-address     Name
M     Signature    10.0.0.l       myrouter.example.com
M     Encryption   10.0.0.1       myrouter.example.com
C     Signature    172.16.0.1     routerA.example.com
C     Encryption   172.16.0.1     routerA.example.com
C     General      192.168.10.3   routerB.domain1.com

This sample shows manually configured special usage RSA public keys for the peer "somerouter." This sample also shows three keys obtained from peers' certificates: special usage keys for peer "routerA" and a general purpose key for peer "routerB."

Certificate support is used in the above example; if certificate support was not in use, none of the peers' keys would show "C" in the code column, but would all have to be manually configured.

The following is sample output when you issue the command show crypto key pubkey rsa name somerouter.example.com:

Router# show crypto key pubkey rsa name somerouter.example.com

Key name: somerouter.example.com

The "reverse" of this access list is used to check the inbound return packets, which are also encrypted. Packets that are denied by the "reverse" access list are dropped because they should have been encrypted but were not.

Extended IP access list check

Access lists that are used to more finely control which data packets are allowed into or out of the IPSec tunnel. Packets that are allowed by the "Extended IP access list" ACL but denied by the "Extended IP access list check" ACL are dropped.

Current peer

Current peer that is being used for this crypto map entry.

Security association lifetime

Number of bytes that are allowed to be encrypted or decrypted or the age of the security association before new encryption keys must be negotiated.

PFS

(Perfect Forward Secrecy) If "Yes," the Internet Security Association (ISAKMP) SKEYID-d key is also renegotiated each time IPSec security association (SA) encryption keys are renegotiated (requires another Diffie-Hillman calculation). Otherwise, the same ISAKMP SKEYID-d key is used when renegotiating IPSec SA encryption keys. ISAKMP keys are renegotiated on a separate schedule, with a default time of 24 hours.

Transform sets

List of transform sets (encryption, authentication, and compression algorithms) that can be used with this crypto map.

Interfaces using crypto map test

Interfaces to which this crypto map is applied. Packets that are leaving from this interface are subject to the rules of this crypto map for encryption. Encrypted packets may enter the router on any interface, and they will be decrypted. Nonencrypted packets that are entering the router through this interface are subject to the "reverse" crypto access list check.

Usage Guidelines

You can get a list of all the active Virtual Private Network (VPN) sessions and of the IKE and IPSec SAs for each VPN session by entering the show crypto session command. The listing will include the following:

Interface

IKE peer description, if available

IKE SAs that are associated with the peer by whom the IPSec SAs are created

IPSec SAs serving the flows of a session

Multiple IKE or IPSec SAs may be established for the same peer (for the same session), in which case IKE peer descriptions will be repeated with different values for the IKE SAs that are associated with the peer and for the IPSec SAs that are serving the flows of the session.

12.0(5)T

This command was introduced.


Usage Guidelines

Use the show ip auth-proxy to display either the authentication proxy entries or the running authentication proxy configuration. Use the cache keyword to list the host IP address, the source port number, the timeout value for the authentication proxy, and the state for connections using authentication proxy. If authentication proxy state is HTTP_ESTAB, the user authentication was successful.

Use the configuration keyword to display all authentication proxy rules configured on the router.

Examples

The following example shows sample output from the show ip auth-proxy cache command after one user authentication using the authentication proxy:

Router# show ip auth-proxy cache

Authentication Proxy Cache
Client IP 192.168.25.215 Port 57882, timeout 1, state HTTP_ESTAB

The following example shows how the show ip auth-proxy configuration command displays the information about the authentication proxy rule pxy. The global idle timeout value is 60 minutes. The idle timeouts value for this named rule is 30 minutes. No host list is specified in the rule, meaning that all connection initiating HTTP traffic at the interface is subject to the authentication proxy rule.

Router# show ip auth-proxy configuration

Authentication cache time is 60 minutes
Authentication Proxy Rule Configuration
Auth-proxy name pxy
http list not specified auth-cache-time 30 minutes

Modification

11.2 P

This command was introduced.

12.3(4)T

The output for the show ip inspect session detail command was enhanced to support dynamic access control list (ACL) bypass.

12.3(11)T

The statistics keyword was added.

12.3(14)T

The output shows the IMAP and POP3 configuration. The vrf vrf-name keyword/argument pair was added.


Usage Guidelines

Use this command to view the CBAC configuration and session information.

ACL Bypass Functionality

ACL bypass allows a packet to avoid redundant ACL checks by allowing the firewall to permit the packet on the basis of existing inspection sessions instead of dynamic ACLs. Because input and output dynamic ACLs have been eliminated from the firewall configuration, the show ip inspect session detail command output no longer shows dynamic ACLs. Instead, the output displays the matching inspection session for each packet that is permitted through the firewall.

Examples

The following example shows sample output for the show ip inspect name myinspectionrule command, where the inspection rule "myinspectionrule" is configured. In this example, the output shows the protocols that should be inspected by CBAC and the corresponding idle timeouts for each protocol.

Router# show ip inspect name myinspectionrule

Inspection Rule Configuration
 Inspection name myinspectionrule
    tcp timeout 3600
    udp timeout 30
    ftp timeout 3600

The following is sample output for the show ip inspect config command. In this example, the output shows CBAC configuration, including global timeouts, thresholds, and inspection rules.

Session audit trail is disabled
one-minute (sampling period) thresholds are [400:500] connections
max-incomplete sessions thresholds are [400:500]
max-incomplete tcp connections per host is 50. Block-time 0 minute.
tcp synwait-time is 30 sec -- tcp finwait-time is 5 sec
tcp idle-time is 3600 sec -- udp idle-time is 30 sec
dns-timeout is 5 sec
Inspection Rule Configuration
 Inspection name myinspectionrule
    tcp timeout 3600
    udp timeout 30
    ftp timeout 3600

The following is sample output for the show ip inspect interfaces command:

show ip trigger-authentication

Syntax Description

Command Modes

Privileged EXEC

Command History

Release
Modification

11.3 T

This command was introduced.


Usage Guidelines

Whenever a remote user needs to be user-authenticated in the second stage of automated double authentication, the local device sends a User Datagram Protocol (UDP) packet to the remote user's host. When the UDP packet is sent, the user's host IP address is added to a table. If additional UDP packets are sent to the same remote host, a new table entry is not created; instead, the existing entry is updated with a new time stamp. This remote host table contains a cumulative list of host entries; entries are deleted after a timeout period or after you manually clear the table using the
clear ip trigger-authentication command. You can change the timeout period with the
ip trigger-authentication (global) command.

Use this command to view the list of remote hosts for which automated double authentication has been attempted.

Examples

The following example shows output from the show ip trigger-authentication command:

Router# show ip trigger-authentication

Trigger-authentication Host Table:
Remote Host          Time Stamp
209.165.200.230       2940514234

This output shows that automated double authentication was attempted for a remote user; the remote user's host has the IP address 209.165.200.230. The attempt to automatically double authenticate occurred when the local host (myfirewall) sent the remote host (209.165.200.230) a packet to UDP port 7500. (The default port was not changed in this example.)

Table 65 show login Field Descriptions 

Field
Description

A default login delay of 1 seconds is applied.

A delay of 1 second is enforced when the login block-for command is issued.

To specify a different delay value, use the login delay command.

No Quiet-Mode access list has been configured.

No access control lists (ACLs) are exempt from the quiet period.

To specify an ACL, use the login quiet-mode access-class command.

All successful or failed login is logged and generate SNMP traps.

Logging messages and Simple Network Management Protocol (SNMP) traps are configured to be generated upon successful or failed login attempts.

To change this setting, use the login on-success or login on-failure command.

Router enabled to watch for login Attacks.

The Cisco IOS device has been configured with at least the login block-for command, which enables default login functionality.

Note If no login parameters are specified, the following description appears: "Router NOT enabled to watch for login Attacks."

If more than 2 login failures occur in 100 seconds or less, logins will be disabled for 100 seconds.

Parameters of the login block-for seconds attempts tries within seconds command.

Router presently in Quiet-Mode, will 
remain in Quiet-Mode for 93 seconds.

The router has switched to quiet mode.

Note If the router is not in quiet mode, the following description appears: "Router presently in Watch-Mode, will remain in Watch-Mode for 95 seconds."

Denying logins from all sources.

The router is in quiet mode and no ACLs are defined, so the router is denying all login requests.

Note If the router is not in quiet mode, the following description, which allows the user to keep track of the current failed login attempts, appears: "Present login failure count 5."


show login failure Sample Outputs

The following sample output from show login failures command shows all failed login attempts on the router:

This command was introduced.


Usage Guidelines

The show parser view command will display information only about the view that the user is currently in. This command is available for both root view users and lawful intercept view users—except for the all keyword, which is available only to root view users. However, the all keyword can be configured by a user in root view to be available for users in lawful intercept view.

The show parser view command cannot be excluded from any view.

Examples

The following example shows how to display information from the root view and the CLI view "first":

Router# enable view
Router# 
01:08:16:%PARSER-6-VIEW_SWITCH:successfully set to view 'root'.
Router# 
! Enable the show parser view command from the root view
Router# show parser view 
Current view is 'root'
! Enable the show parser view command from the root view to display all views
Router# show parser view all 
Views Present in System:
View Name:   first 
View Name:   second 
! Switch to the CLI view "first."
Router# enable view first 
Router#

Maximum waitQ length

Maximum number of entries allowed in the queue, that holds the RADIUS messages that have been sent and are waiting for a response.

Maximum doneQ length

Maximum number of entries allowed in the queue, that holds the messages that have received a response and will be forwarded to the code that is waiting for the messages.

Total responses seen

Number of RADIUS responses seen from the server. In addition to the expected packets, this includes repeated packets and packets that do not have a matching message in the waitQ.

Packets with responses

Number of packets that received a response from the RADIUS server.

Packets without responses

Number of packets that never received a response from any RADIUS server.

Average response delay

Average time from when the packet was first transmitted to when it received a response. If the response timed out and the packet was sent again, this value includes the timeout. If the packet never received a response, this is not included in the average.

Maximum response delay

Maximum delay observed while gathering average response delay information.

Number of RADIUS timeouts

Number of times a server did not respond, and the RADIUS server re-sent the packet.

Duplicate ID detects

RADIUS has a maximum of 255 unique IDs. In some instances there can be more than 255 outstanding packets. When a packet is received, the doneQ is searched from the oldest entry to the youngest. If the IDs are the same, further techniques are used to see if this response matches this entry. If it is determined that this does not match, the duplicate ID detect counter is increased.
