If I take your questions literally then these would be the answers:
1) no you can not set up a router as a TACACS+ server. The router can be a TACACS client but not a server.
2) no you can not set up a router as a RADIUS server. The router can be a RADIUS client but not a server.
3) Yes you can set up a router as an NTP server. To function effectively the router must learn NTP time from some source with reliable authoritative time information. The router can then act as a server for other devices.
4) No you can not set up a router as a syslog server. The router can send syslog to a server but is not a server itself.
5) No you can not set up a router as an SNMP server. The router can send SNMP to a server but is not a server itself.
Technically, the router is the SNMP server. The router is the agent, and the host is the client. A router can send notifications (e.g. traps) to a host manager, but the majority of the traffic flows from manager to agent. IOS can also be made into an SNMP manager (i.e. client) by configuring "snmp-server manager".
I thought in most cases a router would be a SNMP client.
I had no idea you could configure a router as an agent, but that is good news, I want to try the snmp-server manager command. Not sure how to poll the clients now, but maybe someone else could help with this.
Typically, the router is never configured as a client (manager). In fact, the snmp get command in IOS is a hidden command. The manager functionality is used by other internal subsystems of IOS (e.g. DOCSIS).
The recommended approach is to let the router be the agent, and a host (UNIX, Windows, etc.) be the manager.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
