Chapter 15 Statistics

Monitoring | 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 and 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 requests 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.
