CCNPv6 TSHOOT DLS1#debug aaa authorization AAA Authorization debugging is on DLS1# Dec 7 16:06:34.836: AAA/AUTHOR (0xD): Pick method list 'default' - FAIL Dec 7 16:06:34.844: AAA/AUTHOR/EXEC(0000000D): Authorization FAILED The above example shows the method list defined and being used for AAA authorization (default). Note that the authorization attempt failed. SSH-related Commands R3#show ip ssh SSH Enabled - version 1.99 Authentication timeout: 120 secs; Authentication retries: 3 Minimum expected Diffie Hellman key size : 1024 bits R3#show ip ssh SSH Disabled - version 1.99 %Please create RSA keys (of at least 768 bits size) to enable SSH v2. Authentication timeout: 120 secs; Authentication retries: 3 Minimum expected Diffie Hellman key size : 1024 bits The first example above shows the output when the RSA keys have been created and SSH is enabled. The second example shows the output when there are no RSA keys and SSH is disabled. R3#show ssh Connection Version Mode Encryption Hmac State Username 0 2.0 IN aes256-cbc hmac-sha1 Session started raduser 0 2.0 OUT aes256-cbc hmac-sha1 Session started raduser 1 2.0 IN aes256-cbc hmac-sha1 Session started admin 1 2.0 OUT aes256-cbc hmac-sha1 Session started admin %No SSHv1 server connections running. The above example shows active SSH connections with the username, version, mode, encryption, HMAC, and state of the connection. ACL-related Commands R3#show access-lists Standard IP access list 1 10 permit 10.1.80.100 (77 matches) The above example shows the currently configured ACLs with the type, number (if one is assigned), statements, and the number of matches for each one. R3#show ip interface fa0/0 FastEthernet0/0 is up, line protocol is up Internet address is 10.1.80.1/24 Broadcast address is 255.255.255.255 Address determined by non-volatile memory MTU is 1500 bytes Helper address is not set Directed broadcast forwarding is disabled Multicast reserved groups joined: 224.0.0.10 Outgoing access list is not set All contents are Copyright © 1992–2010 Cisco Systems, Inc.
