Brocade VDX - TACACS

pawarpavan — Tue, 22 Aug 2023 06:52:50 GMT

Hello Experts,

I'm configuring the TACACS+ on the VDX switch and I was able to configure 'aaa authentication and aaa accounting' but did not find an option to configure authorization even though I have configured the tacacs+ host.

extreme01# show running-config tacacs-server

tacacs-server host 10.128.64.148 use-vrf mgmt-vrf

key "W04/vBJigwC0HIB1wvPEuHkqAboiDhOa9rYs+fyZiTU=\n"

encryption-level 7

retries 3

extreme01(config)# aaa ?

Possible completions:

accounting Configure Login or Command accounting

authentication Configure preferred order for Authentication

extreme01(config)# aaa

Is authorization not supported on the version I'm running on VDX?

SW - 7.3.0aa (NOS)

HW - BR-VDX6740

Pavan,

I see that you have not received a response on this question that was posted some time ago. I looked into our documentation and I see instruction in the 7.3.0 security guide on setting up aaa authorization, however no such reference in the command reference guide. I also am not seeing an option to configure it in my lab. Looking into our Release notes I do not see any mention of support for aaa authorization in 7.3.0.

I then checked my internal training and the old road maps for NOS and It looks like aaa authorization was introduced in 7.4.0. I then checked the security guide, command reference, and release notes and they all show that this feature was implemented in 7.4.0.

Additionally I upgraded my lab to 7.4.0 and have no issues configuring the feature:
