Not getting it. Perhaps if we get a little more specific. Today, I can ssh into my mds switch and auth via radius with my userid:
9216-2# sh run | incl radi
radius-server key 7 "radiuskeyhere"
radius-server host 10.10.10.67 authentication
radius-server host 10.10.10.99 authentication
aaa authentication login default group radius local
aaa authentication login console group radius local
but if I try to use that same userid at the FM, Discover New Fabric - Fabric Manager screen, I get a msg, SnmpReport: Unknown User Name. If I use the locally defined user, admin, on the switch I can login in:
snmp-server user admin network-admin auth md5 keyvaluehere localizedkey
I'm not finding a discription of how to get the radius defined users to be able to connect at that Discover New Fabric screen.
I think I see the problem now. When you said, "The MDS is capable of authenticating users via tacacas+ through both the vty and fabric manager interfaces. (in reality they are both a view into the same thing)," I believe you are talking about ssh/telnet login to the switch via FM.
I'm wanting to get the SNMPv3 login at "Discover New Fabric" screen to use radius to auth the users centrally. There is no mention of this in the chapter on snmpv3 configuration. Creating and Modifying Users only talks about locally defined users.
Still not working, EMC tac opens case with cisco tac. Weeks pass. While the sentence above might lead one to believe this is a feature, no other doc hints at use of it. I wonder, does anyone on the planet really auth with radius when at the "Discover New Fabric" screen or is everyone using snmp user defined on the seed switch?
