CISCO-REMOTE-ACCESS-MONITOR-MIB
Acronyms and Definitions The following acronyms and terms are used in this document: IPSec: Secure IP Protocol VPN: Virtual Private Network RAS: Remote Access Service ISP: Internet Service Provider. LAN: Local Area Network Group: A collection of remote access users grouped and managed together as a single entity for administrative convenience. Session: A Remote Access Session. Overview of the MIB This is a MIB Module for monitoring the structures in Virtual Private Networks based remote access networks. The MIB seeks to create a common model of Remote Access across implementations of the service on layer 2 (PPTP, L2TP, L2F), layer 3 (IPsec) and layer 4 (SSL) virtual private networks. The MIB defines counters and objects of interest to performance/fault monitoring in a way which is independent of the technology of the remote access implementation. MIB contains eight major groups of objects which are used to manage Remote Access connections: a) Remote Access capacity group This section defines metrics to gauge the limits of resources on this device which are critical to RAS service. b) Remote Access resource usage group This section defines metrics to gauge the usage of resources on this device which are critical to RAS service service. c) Current activity and performance of RAS service This section defines metrics to gauge the current remote access activity. d) Remote Access Service failures This section defines metrics to monitor session failures and failures of the service itself, measured at aggregate level, session level and group level. e) Security violations in the Remote Access service This section defines metrics which reflect the state of remote access service of interest to Security Operations staff in an enterprise. f) Threshold group (allows definition of high water marks) This section allows the management entity to define thresholds to set high water marks on critical metrics. g) Notifications This section defines notifications to signal significant events pertaining to the Remote Access Service.
