• MIB-2 Transmission Control Protocol Group (TCP) , RFC1213-MIB, OID:
1.3.6.1.2.1.6. Contains information used to keep track of the application entities using
TCP on the switch CPU.
• MIB-2 User Datagram Protocol Group (UDP), RFC1213-MIB, OID: 1.3.6.1.2.1.7.
Contains information used to keep track of the application entities using UDP on the
switch CPU.
• MIB-2 SNMP Group, RFC1213-MIB, OID: 1.3.6.1.2.1.11. Contains information used
to keep track of SNMP application entities. It provides statistical information about the
SNMP protocol entity and tracks the amount of management traffic that the switch
CPU responds to.
• BRIDGE-MIB dot1dBridge dot1dStp Group, RFC1493, OID: 1.3.6.1.2.1.17.2. This
MIB holds Spanning Tree Protocol information on per port basis.
• ifMIB ifMIBObjects ifxTable Group, RFC2863, OID: 1.3.6.1.2.1.31.1.1. Contains
network load on per port basis and represents an extension to the MIB2-Interface
group.
• ifMIB ifRcvAddressTable Group, RFC2863, OID: 1.3.6.1.2.1.31.1.4. Contains
network MAC table on the switch CPU.
Originally, SNMP was designed for networks designed using Hubs. Network bandwidth
allocated for SNMP had to be kept to a minimum and hence the Simple Network Management
Protocol was designed to be simple. Therefore, an SNMP manager can carry out the
following simple commands:
• Query SNMP agents
• Get responses from agents
• Set variables in agents
• Acknowledge asynchronous events from agents
9.1 Westermo OnTime private MIB Information
The Westermo OnTime Management Information Base (MIB) is a collection of variables or
data that determines the properties of the managed device. The MIB is unique to the
Westermo OnTime device and has therefore been compiled to take this into account.
There are various tools available that enable the MIB data to be displayed in a software
package or via OPC so that the MIB information can be displayed onto a SCADA.
The Westermo OnTime MIB is available on the documentation / software CD that is included
with every Westermo OnTime switch
The Westermo OnTime private MIB contains the following:
• General
• FRNT 0 status
• Status information
• Time synchronization configuration parameters and status information
• Multicast configuration
