Radius configuration - E3800-48G-​PoE+ J9574A

[DavidSawyer]

I've set up a radius server and all works fine...except one part.

Here is the config...

*************************************************************

radius-server host 192.168.x.x
radius-server key "xxxxxxxxxxxxxxxxxxxxx"

aaa accounting exec start-stop radius
aaa authentication telnet login radius local
aaa authentication telnet enable radius local
aaa authentication ssh login radius local
aaa authentication ssh enable radius local

*************************************************************

The radius works fine, but it doesn't use local authentication as secondary, is there something else I need to configure?

What version software are you using?

I am using K.15.04.0003 and here is my config:

radius-server host 10.100.100.230 key "$XXXXXXXX"

radius-server host 10.100.100.1 key "$XXXXXXXX"

aaa authentication console login radius local
aaa authentication telnet login radius local
aaa authentication ssh login radius local

though it doesn't show in the config, did you use

password operator user-name XXXXXXX plaintext XXXXXXXX

to create a local user?

[DavidSawyer]

Yes, there is a local user account, I've removed the radius configuration and the local account works fine.

[JWag44]

How are you testing the local account?  I have noticed that if I try to use local credentials while the radius server is still accessible via the network, it will not work.  Is it possible to test with the switch off the network?  Or disable the radius server temporarily?

[JWag44]

Also, what are you using for the radius server.  I use Microsoft IAS, and I can use the server's System Event Log to find Event ID 13 messages like this:

Event Type: Error
Event Source: IAS
Event Category: None
Event ID: 13

Description:
A RADIUS message was received from the invalid RADIUS client IP address 10.100.5.10.

Did you ever get this figured out?  I still think that if you try to login with the local account, it is not going to work while the radius server is accessible.

[Pete W]

The secondary authentication method only comes into play if the primary method is unavailable/fails to respond/etc. For testing purposes, you could simulate this scenario with an ACL, or temporarily remove/modify the RADIUS client details in IAS.

Below is the error i get from my RADIUS server, the IP for my router is 1076.0.1 and not 10.76.12.1 as displayed  by the router. I have vland 12 setup on my switch and scope for vlan 12 on my server. Any help will be greatly appreciated.

Thanks

"Below is the error i get from my RADIUS server, the IP for my router is 1076.0.1 and not 10.76.12.1 as displayed  by the router."   and   "A RADIUS message was received from the invalid RADIUS client IP address 10.76.12.1."

I expect you have the "radius client" defined as 10.76.0.1....but the RADIUS request is "sourced" from the 10.76.12.1 interface, hence the error message.

If you add the following statement, the RADIUS request will source from the 10.76.0.1 address, regardless of the connected interface:

    'ip sourceinterface radius 10.76.0.1'

A good source of info, the HP Networking and Cisco CLI Reference Guide. A free CLI ref of ProVision, Comware5, and Cisco in side-by-side comparison. Not all inclusive, but alot of the "daily" config needs.  ....and it's free!

Also good if you have a single platform :-)

Thanks for the response Jeff,
 but  ip sourceinterface radius 10.76.0.1 returns Invalid input: sourceinterface

[EckerA]

try

ip source-interface ...

hth

[boziah]

nope, actually there is no ip source-interface command on my switch, maybe on other models.

mose(config)# ip sour
 source-binding
 source-lockdown
 source-route
mose(config)# ip source-interface
Invalid input: source-interface

[jefflj]

what version of SW are you running? I have the most current version and the command (from the config context) is:
ip source-interface radius <ip addr>
