show crypto ipsec transform
Displays the specific configuration for one or all transformation sets.
show crypto ipsec default transform-set
To display the default IP Security (IPsec) transform sets currently in use by Internet Key Exchange (IKE), use the show crypto ipsec default transform-set command in privileged EXEC mode.
show crypto ipsec default transform-set
Syntax Description
This command has no arguments or keywords.
Command Modes
Privileged EXEC (#)
Command History
12.4(20)T
This command was introduced.
Cisco IOS XE Release 2.4
This command was implemented on the Cisco ASR 1000 series routers.
Usage Guidelines
If the default transform sets are in use, the show crypto ipsec default transform-set command displays the two default transform sets each of which defines an Encapsulation Security Protocol (ESP) encryption transform type and an ESP authentication transform type.
Examples
The following example displays the two default transform sets. No user defined transform sets have been configured, the default transform sets have not been disabled, and the crypto engine supports the encryption algorithm.
Router# show crypto ipsec default transform-setTransform set #$!default_transform_set_1: { esp-aes esp-sha-hmac }will negotiate = { Transport, },Transform set #$!default_transform_set_0: { esp-3des esp-sha-hmac }will negotiate = { Transport, },Table 91 show crypto ipsec default transform-set Field Descriptions
The following example shows that when the default transform sets are disabled with the no crypto ipsec default transform-set, the show crypto ipsec default transform-set has no output.

Usage Guidelines
If no keyword is used, all SAs are displayed. They are sorted first by interface and then by traffic flow (for example, source or destination address, mask, protocol, or port). Within a flow, the SAs are listed by protocol (ESP or AH) and direction (inbound or outbound).

Command History
12.4(20)T
This command was introduced.
Cisco IOS XE Release 2.4
This command was implemented on the Cisco ASR 1000 series routers.
Usage Guidelines
If you have neither manually configured IKE policies with the crypto isakmp policy command nor issued the no crypto isakmp default policy command, IPsec will use the default IKE policies to negotiate IKE proposals. There are eight default IKE default policies supported (see Table 95). The default IKE policies define the following policy set parameters:

Table 95
Default IKE Policies
If you have manually configured IKE policies and you issue the show crypto isakmp default policy command there is no output, since the default IKE policies are not in use.
Examples
The following example displays the eight default policies with protection suites of priorities 65507-65014. The default policies are displayed since there are no user configured policies, the default policies have not been disabled, and EzVPN is not configured.

Usage Guidelines
There are eight default IKE default policies supported with protection suites of priorities 65507-65514, where 65507 is the highest priority and 65514 is the lowest priority.

show crypto key pubkey-chain rsa
To display the Rivest, Shamir, and Adelman (RSA) public keys of the peer that are stored on your router, use the show crypto key pubkey-chain rsa command in User EXEC or privileged EXEC mode.
show crypto key pubkey-chain rsa [address key-address | name key-name | vrf vrf-name [address ip-address]]
Cisco IOS Release 12.2(33)SXI
show crypto key pubkey-chain rsa [name key-name]
Syntax Description
Command Modes
User EXEC (>)
Privileged EXEC (#)Command History
Usage Guidelines
This command shows RSA public keys stored on your router. These include RSA public keys of peer routers manually configured on 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 the certificates are lost. The public key is derived again when the router requests for certificates.
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:

The peer router can be either Router A or Router B. This sample also shows three keys obtained from the certificates of peer routers: special usage keys for peer "routerA" and a general purpose key for peer "routerB."
If certificate support is not used, none of the keys of the peer router show "C" in the code column. You must configure them manually.

show crypto map (IPsec)
To display the crypto map configuration, use the show crypto map command in user EXEC or privileged EXEC mode.
show crypto map [gdoi fail-close | interface interface | tag map-name]
Syntax Description
Command Default
No crypto maps are shown.
Command Modes
User EXEC (>)
Privileged EXEC (#)
Command History
Usage Guidelines
The show crypto map command allows you to specify a particular crypto map. The crypto maps shown in the command output have been dynamically generated; the user does not have to configure crypto maps in order for them to appear in this command output.
There are two default transform sets supported in Cisco IOS k9 images only:
•
•
The show crypto map command will display the default transform sets if there are no other transform sets configured for the crypto map, you have not disabled the default transform sets by issuing the no crypto ipsec default transform-set command, and the crypto engine supports the encryption algorithm.
Examples
The following example shows that crypto input and output ACLs have been configured:
