# Graphing the SNMP tab using EDM

Use the following procedure to view read-only statistical information about SNMP traffic in the SNMP tab.

## Procedure steps

1. From the navigation tree, double-click Graph.

2. In the Graph tree, double-click Chassis.

3. In the work area, click the SNMP tab to view the SNMP statistical information.

## Variable definitions

The following table describes the fields of SNMP tab.

Field | Description
--- | ---
InPkts | Indicates the total number of messages delivered to the SNMP from the transport service.
OutPkts | Indicates the total number of SNMP messages passed from the SNMP protocol to the transport service.
InTotalReqVars | Indicates the total number of MIB objects retrieved successfully by the SNMP protocol as the result of receiving valid SNMP Get-Request and Get-Next PDUs.
InTotalSetVars | Indicates the total number of MIB objects altered successfully by the SNMP protocol as the result of receiving valid SNMP Set-Request PDUs.
InGetRequests | Indicates the total number of SNMP Get-Request PDUs that have been accepted and processed by the SNMP protocol.
InGetNexts | Indicates the total number of SNMP Get-Next PDUs accepted and processed by the SNMP protocol.
InSetRequests | Indicates the total number of SNMP Set-Request PDUs accepted and processed by the SNMP protocol.
InGetResponses | Indicates the total number of SNMP Get-Response PDUs accepted and processed by the SNMP protocol.
OutTraps | Indicates the total number of SNMP Trap PDUs generated by the SNMP protocol.
OutTooBigs | Indicates the total number of SNMP PDUs generated by the SNMP protocol for which the value of the error-status field is tooBig.
OutNoSuchNames | Indicates the total number of SNMP PDUs generated by the SNMP protocol for which the value of the error-status field is noSuchName.
OutBadValues | Indicates the total number of SNMP PDUs generated by the SNMP protocol for which the value of the error-status field is badValue.
OutGenErrs | Indicates the total number of SNMP PDUs generated by the SNMP protocol for which the value of the error-status field is genErr.
InBadVersions | Indicates the total number of SNMP messages delivered to the SNMP protocol for an unsupported SNMP version.
InBadCommunityNames | Indicates the total number of SNMP messages delivered to the SNMP protocol that used an unknown SNMP community name.
InBadCommunityUses | Indicates the total number of SNMP messages delivered to the SNMP protocol that represented an SNMP operation not allowed by the SNMP community named in the message.
InASNParseErrs | Indicates the total number of ASN.1 or BER errors encountered by the SNMP protocol after decoding received SNMP messages.
InTooBigs | Indicates the total number of SNMP PDUs delivered to the SNMP protocol for which the value of the error-status field is tooBig.
InNoSuchNames | Indicates the total number of SNMP PDUs delivered to the SNMP protocol for which the value of the error-status field is noSuchName.
InBadValues | Indicates the total number of SNMP PDUs delivered to the SNMP protocol for which the value of the error-status field is badValue.
InReadOnlys | Indicates the total number of SNMP PDUs delivered to the SNMP protocol for which the value of the error-status field is readOnly. This error is a protocol error to generate an SNMP PDU containing the value "readOnly" in the error-status field. This object is provided to detect incorrect implementations of the SNMP.
InGenErrs | Indicates the total number of SNMP PDUs delivered to the SNMP protocol for which the value of the error-status field is genErr.
