Monitoring | Statistics | MIB-II
This section of the Manager lets you view statistics that are recorded in standard MIB-II objects on the
VPN 3002. 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 3002 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.
• 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 3002 SNMP server, see the Configuration | System | Management
Protocols | SNMP screen.
