Monitor | Statistics | MIB-II
This section of the Manager lets you view statistics that are recorded in standard MIB-II objects on the
VPN Concentrator. MIB-II (Management Information Base, version 2) objects are variables that contain
data about the system. They are defined as part of the Simple Network Management Protocol (SNMP);
and SNMP-based network management systems can query the VPN Concentrator to gather the data.
Each subsequent screen displays the data for a standard MIB-II group of objects:
•Interfaces: packets sent and received on network interfaces and VPN tunnels.
•TCP/UDP: Transmission Control Protocol and User Datagram Protocol segments and datagrams sent
and received, etc.
•IP: Internet Protocol packets sent and received, fragmentation and reassembly data, etc.
•RIP: Routing Information Protocol global route changes, bad packets a nd bad routes received, etc.
•OSPF: Open Shortest Path First protocol LSA data, Area data, etc.
•ICMP: Internet Control Message Protocol ping, timestamp, and address mask requ ests and replies, etc.
•ARP Table: Address Resolution Protocol physical (MAC) addresses, IP addresses, and mapping types.
•Ethernet: errors and collisions, MAC errors, etc.
•SNMP: Simple Network Management Protocol requests, bad community strings, parsing errors, etc.
To configure and enable the VPN Concentrator’s SNMP server, see the Configuration | System |
Management Protocols | SNMP screen.
