Cisco AAA/Identity/Nac :: 3845 - Enable Secret Password Missing In Configuration
Jun 23, 2011
Recently I came across a router (Cisco 3845, IOS 12.4) configured for TACACS, one local username and an enable password. Going through the configuration I noticed the router didn't have an enable secret password which I thought was strange. The TACACS config is below, comments regarding the TACACS config and the consequences of not having an enable secret or if there is a need for one.
aaa authentication login default group tacacs+ aaa authentication login no_tacacs enable aaa authorization exec default group tacacs+ aaa authorization commands 1 default group tacacs+ aaa authorization commands 15 default group tacacs+ aaa accounting exec default start-stop group tacacs+ aaa accounting commands 1 default start-stop group tacacs+ aaa accounting commands 15 default start-stop group tacacs+ aaa accounting network default start-stop group tacacs+

How to configure authentication of enable password using acs 5.3. I have installed acs 5.3 and created user and gave relevant passwords. Following config is done on router
aaa new-model
aaa authentication login default group tacacs+ local
aaa authen enable default group tacacs+ enable
tacacs-server host x.x.x.x key xxxxx
Now when I telnet router, i can authenticate username/pass with acs5.3 but when i try to enter enable command and give password, it gives me error in authentication. What is the process of configuring enable passwords?

I have migrated my ACS data from 4.1 to 5.1 and everything is working fine to test the connection I have configured a switch to get the authentication from the new Tacacs server, using my old username and password..i got in perfectly but when the switch asked my for enable which is the same password, it refused the password.(I have unchecked the <use a different password for enable> option) I deleted my switch from the Tacacs to enter locally, I went in with no problems..i thought that the problem may be from the old configuration.so I created a new username and password to check, and the problem still exist.

Changed my AD password and now i cannot get into the enable side of the cisco switches on our network (we have no routers).Looking on the logs for the ACS v4.2 I can see the following -
On TACACS+ Accounting you can see the connections which have worked - it the initial tty connections -
When i look in the failed attempts i see the following Auth failed - External DB user invalid or bad password or on another occasion internal error or EAP-TLS or PEAP authentication failed due to unknown CAcertificate during SSL handshake.

I have been experimenting with acs 4.2 and a cisco asa 5510. I have managed to authenticate the ASA users with my tacacs server. The user "test" is authenticated with the tacacs server, and can log in. But the enable password is wrong, because i dont know where to place it in the tacacs server.
Now my question is, where do i set my enable password when authenticatig with tacacs+. And for this i mean in the acs 4.2, i know how to do it on the asa.

We currently have a distributed PR and DR ACS 5.3 setup, set up with tacacs devices and one radius device.The radius device is used Opnet's AppResponse Xpert Admin. We are trying to intergrate AppResponse Xpert Admin with ACS.
The GUI for AppResponse Xpert Admin is asking for the radius server ip address - i.e our ACS , radius port - i.e 1812 and "secret" - I'm guessing this means the shared secret of the actual ACS itself (not the shared secret used by network devices) .
On our ACS 4.2 systems we have a field for a shared secret regarding the ACS server itself (to authorise replication?).
Using the search function for "Shared Secret" in pdf "User Guide for Cisco Secure Access Conrol System 5.3" has only found references to setting one for network devices and not a field for the ACS itself.Is a ACS server shared secret still relevant for the ACS 5.x system?

I am trying to migrate an ACS 4.1.1(24) using the migraton tool to ACS 5.2. The tool is working OK. It migrates the users, groups, NDG, etc. and the reports are showing no errors.
The problem is with the Enable password of the users. The users in the ACS 4 have the TACACS+ Enable Password configured, but after the migration it appears empty in the ACS 5.

I have two routers 3845 and HSRP is configured properly. Currently we are using default route to ISP and right now I want to use BGP as I have 3 Public pools and that's why I want to advertise in the public network. How I can configure that in my Router.

I have a 3845 that I am trying to configure but it won't save. It doesn't matter what i do (write mem, copy run start). No matter what, if I reload it, it wipes the config. Am I missing something, or is it just a bad memory? I don't get any errors when I save, it looks like it takes, but no dice.

I have a 50 Mbps metro ethernet connection between our main office, and our collocation site, where we store web servers, DR equipment and VPN access gateways. I have two Cisco 3845 ISR's connected to the metro E circuit. The interfaces on each router are configured as 100/full as requested by my ISP. We are connected via ethernet to a fiber media converter.
As I understand, CBFWQ will not kick in until congestion occurs on an interface. I also understand that the bandwidth command on an interface is to provide bandwidth related information to upper level protocols (like EIGRP, etc).
My question is that since the interface where I have CBWFQ configured on is at 100 Mbps, but my circuit is at 50Mbps, how can I get my routers to kick CBWFQ in when traffic demand exceeds 50Mbps+? Does the bandwidth command on the interface control that as well?

When I upgraded my cisco 3750 ME from c3750me-i5k91-mz.122-46.SE to c3750me-i5k91-mz.122-58.SE2.bin all commands for radius disappeared? However, there are a lot of commands to ldap which was missing in the previous version. Seems as if the radius has disappeared and been replaced by ldap?

I have 3945 Router and I have bought NM-16ESW-1G1G card. After installed the card no interface shows on show ip interface brief or Show run command . When i end the switch module then i have found the interface. previously i have worked on NM-16ESW card on my 3845 router where interface card interface shows in my show run and interface command and i have assign IP and crypto map fro my Branch.
So my question is NM-16ESW-1G1G is different then NM-16ESW card ? if not then why i can not find interface. if Different then i have need to configure interfcae by enter the switch module seperately ?

I got a config of a SoHo96 router, which has an IPSec Tunnel configured. Now I need to understand what's configured there and it seems that the parameters that aren't being explicitly set, do not show up in the config. Thus, I have no clue about DH Groups, Keylife times and other nice things.How do I reveal the "missing" configuration items?

Environment :AP 2602, WLC 5508 V7.4, ISE 1.1.2, Prime Infras 1.2
For a specific SSID, we use MAC address as 1 of the conditions to authorize access only for the company-owned mobiles (smartphones and tablets), the other condition being, for the mobile, to present a valid AD user/password;this way, the so-called BYODs are rejected since this is the rule within this company ;The difficulty with this approach is the fact that there is no way in ISE Identities Endpoints nor Groups to associate a user-friendly name to the MAC address of the mobiles, which makes very tedious some actions such as a search in the ISE authentication Log based on the MAC address value itself;the question is just to know if it is planned to add a new field in Identities Endpoints definition that would allow to associate a user-friendly name to a MAC address, for future ISE versions,

I have a problem trying to export logs to the Cisco ACS View from my ACS 4.2In the document [URL] Cisco states that one of the mandatory attributes for export to work is "Network Access Profile Name" under TACACS+ Accounting (under ACS 4.2 System configuration -> Logging settings). Well, I don't have this mandatory attribute listed in ACS under TACACS+ accounting log configuration. I tried to ignore this attribute, but then ACS View complains about null value for the attribute mentioned above.Is this some bug in ACS View or ACS or maybe I simply missing something?
