The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

•Feature Information for Frame Relay MIB Enhancements
The tasks in this document assume that you have configured Frame Relay and SNMP on your devices.
To access the information introduced by the Frame Relay MIB enhancements, you must have the Cisco Frame Relay MIB in the MIB file called CISCO-FRAME-RELAY-MIB.my compiled in your network management system (NMS) application.
•Frame Relay-ATM Network Interworking (FRF.5)
•Frame Relay-ATM Service Interworking (FRF.8)
•Frame Relay switching
The Cisco Frame Relay MIB describes managed objects that enable users to remotely monitor Frame Relay operations using SNMP. The Frame Relay MIB Enhancements feature extends the Cisco Frame Relay MIB by adding MIB objects to monitor the following Frame Relay functionality:
•Frame Relay fragmentation
•Input and output rates of individual virtual circuits (VCs)
Table 1 describes the MIB tables and objects that are introduced by the Frame Relay MIB enhancements. For a complete description of the MIB, see the Cisco Frame Relay MIB file CISCO-FRAME-RELAY-MIB.my, available through Cisco.com at the following URL:
http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml
The Frame Relay MIB Enhancements feature also modifies the load-interval command to enable you to configure the load interval per permanent virtual circuit (PVC). The load interval is the length of time for which data is used to compute load statistics, including input rate in bits and packets per second, output rate in bits and packets per second, load, and reliability. Before the introduction of this feature, the load interval could be configured only for the interface.
The Frame Relay MIB Enhancements enable you to use SNMP to monitor the following:
•Frame Relay fragmentation
•Frame Relay-ATM Network Interworking (FRF.5)
•Frame Relay-ATM Service Interworking (FRF.8)
•Frame Relay switching
•Input and output rates of individual virtual circuits (VCs)
•Setting the Load Interval for a PVC
You can change the period of time over which a set of data is used for computing load statistics. Decisions, such as for dial backup, depend on these statistics. If you decrease the load interval, the average statistics are computed over a shorter period of time and are more responsive to bursts of traffic.
To change the length of time for which a set of data is used to compute load statistics for a PVC, use the following commands beginning in interface configuration mode:
|
|
|
---|---|---|
Step 1 |
Router(config-if)# frame-relay interface-dlci dlci |
Assigns a specific PVC to a DLCI1 , and enters Frame Relay DLCI configuration mode. |
Step 2 |
Router(config-fr-dlci)# load-interval seconds |
Changes the length of time for which data is used to compute load statistics. The seconds argument must be a multiple of 30. The range is from 30 to 300 seconds. The default is 300 seconds. |
1 DLCI = data-link connection identifier |
Use the show running-config command to verify that you have configured the load interval correctly.
•Setting the Load Interval for a PVC Example
In the following example, the load interval is set to 60 seconds for a Frame Relay PVC with the DLCI 100:
interface serial 1/1
frame-relay interface-dlci 100
load-interval 60
