Hey Christopher,
   
  You're the best. Thanks for all your help.

  aaa new-model
  tacacs-server host 1.1.1.1 key cisco
  radius-server host 1.1.1.1 auth-port 1645 acct-port 1646 key cisco
   
   
  For the PIX just configure two sets of aaa-server commands with different aaa group names.
   
  aaa-server TAC-1 protocol tacacs+
  aaa-server TAC-1 (inside) host 1.1.1.1 cisco timeout 10
  aaa-server RAD-1 protocol radius
  aaa-server RAD-1 (inside) host 1.1.1.1 cisco timeout 10
   
  On the AAA Server just configure two AAA clients under the Network Configuration with different names with the same ip address and then chose the correct protocol for tacacs or radius.
   
  HTH.

  Hey Christopher,

This is great to know. Thanks for posting this info.

But, thinking about what you're saying, I'm not sure how this would be configured on the AAA client side.

When the protocol (Tacacs or Radius) is specified, you can only enter one protocol. So, would you config 2 AAA groups, one for Tacacs and another for Radius and just point each group to the same ACS server address?

Also, how is this configured on the ACS side?

Thanks again, A

  Actually this changed in 3.3 ACS code.

You can now have a device communicate to the same ACS via TACACS and
RADIUS at the same time.

Unless it has changed in version 4.0, that is not possible.

You can only have one entry for each network device and it needs to be
configured as a TACACS or RADIUS client, not both.

Hi all,

I noticed that some ACS features require Radius eg downloadable acl's
while other features require Tacacs+ eg command accounting.

If I wanted to use both features but only had a single ACS server
would
that be possble?

If so, how would I configure a single ACS to run both Tacacs+ and
Radius
simultaneously?

Thanks in advance
