We've recently implemented ACLs to block network ranges from telneting to ur routers and switches from unauthorised IP address ranges which is working well. We would like to log attempts from blocked ranges, preferably to our NMS via an SNMP trap. Is this possible at all? We already have TACACS+ logging to an ACS server for failed login attempts and could turn on syslogging, but would like to do it via SNMP so that the manager can see an instant alert from our NMS server screen which is SNMP only.
Many thanks for any help.
