Finding Feature Information
Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module.
Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to www.cisco.com/go/cfn. An account on Cisco.com is not required.
Feature Overview
The Frame Relay 64-Bit Counters feature provides 64-bit counter support on Frame Relay interfaces and subinterfaces. This feature enables the gathering of statistics through Simple Network Management Protocol (SNMP) for faster interfaces operating at OC-3, OC-12, and OC-48 speeds.
The following counters are supported by this feature: Bytes In, Bytes Out, Packets In, and Packets Out.
The show frame-relay pvc command has been modified to display the 64-bit counters.
Benefits
The values in 32-bit counters sometime wrap because the field is too small. Wrapping causes the values in these fields to become meaningless. The 64-bit counters support the reliable gathering of statistics by SNMP by preventing the wrapping of counter values.
Restrictions
SNMP cannot retrieve 64-bit virtual-circuit (VC) counters.

Platform Support Through Feature Navigator
Cisco IOS software is packaged in feature sets that support specific platforms. To get updated information regarding platform support for this feature, access Feature Navigator. Feature Navigator dynamically updates the list of supported platforms as new platform support is added for the feature.
Feature Navigator is a web-based tool that enables you to quickly determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image.
To access Feature Navigator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check will verify that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password will be e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions at http://www.cisco.com/register.
Feature Navigator is updated when major Cisco IOS software releases and technology releases occur. As of May 2001, Feature Navigator supports M, T, E, S, and ST releases. You can access Feature Navigator at the following URL:
http://www.cisco.com/go/fn
Supported Standards and MIBs and RFCs
Standards
No new or modified standards are supported by this feature.
MIBs
The frame-relay ifmib-counter64command modifies the interface MIB (IF-MIB) by allowing slower Frame Relay interfaces and subinterfaces to be included in the 64-bit interface MIB counters.
To obtain lists of supported MIBs by platform and Cisco IOS release, and to download MIB modules, go to the Cisco MIB website on Cisco.com at the following URL:
http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml
RFCs
No new or modified RFCs are supported by this feature.
Prerequisites
This document assumes that you know how to configure Frame Relay and SNMP support using Cisco IOS software.

- Enabling Only Slower Frame Relay Subinterfaces for 64-Bit Interface MIB Counters Example
Enabling Slower Frame Relay Interfaces and Subinterfaces for 64-Bit Interface MIB Counters Example
In the following example, the frame-relay ifmib-counter64 command is used with the if keyword to enable serial interfaces 6/0/1:0, 6/0/2:0, and 6/0/3:0 and related subinterfaces to be included in the 64-bit interface MIB counters. The example also shows corresponding output for the show frame-relay pvccommand and the corresponding statistics for the 64-bit interface MIB counters.
interface Serial6/0/1:0 ip address 1.1.1.1 255.255.255.0 encapsulation frame-relay no ip route-cache cef no ip route-cache frame-relay interface-dlci 101 no frame-relay inverse-arp frame-relay ifmib-counter64 if interface Serial6/0/2:0 no ip address encapsulation frame-relay no ip route-cache cef no ip route-cache no frame-relay inverse-arp frame-relay ifmib-counter64 if ! interface Serial6/0/2:0.1 point-to-point ip address 2.1.1.1 255.255.255.0 no ip route-cache frame-relay interface-dlci 201 ! interface Serial6/0/3:0 ip address 3.1.1.1 255.255.255.0 encapsulation frame-relay frame-relay interface-dlci 301 no frame-relay inverse-arp frame-relay ifmib-counter64 if interface Serial6/0/3:0.1 point-to-point ip address 3.1.2.1 255.255.255.0 frame-relay interface-dlci 302
The following example shows corresponding sample output for the show frame-relay pvc command with the 64-bit keyword. Note that the frame-relay ifmib-counter64command does not affect the output of the show frame-relay pvccommand.
Router# show frame-relay pvc 101 64-bit DLCI = 101, INTERFACE = Serial6/0/1:0 input pkts 231 output pkts 228 in bytes 23604 out bytes 23502 Router# Router# show frame-relay pvc 201 64-bit DLCI = 201, INTERFACE = Serial6/0/2:0.1 input pkts 1453 output pkts 1408 in bytes 335024 out bytes 327272 Router# Router# show frame-relay pvc 301 64-bit DLCI = 301, INTERFACE = Serial6/0/3:0 input pkts 510 output pkts 508 in bytes 52690 out bytes 52622 Router# Router# show frame-relay pvc 302 64-bit DLCI = 302, INTERFACE = Serial6/0/3:0.1 input pkts 957 output pkts 912 in bytes 283246 out bytes 275493 Router#
The following output from an SNMP inquiry shows that the 64-bit interface MIB counters include the interfaces configured above:
ifHCInOctets.5 = 0x000000000 ifHCInOctets.16 = 0x000000000 ifHCInOctets.17 = 0x003360d33 ifHCInOctets.18 = 0x000000000 ifHCInOctets.19 = 0x000000000 ifHCInOctets.20 = 0x000000000 ifHCInOctets.24 = 0x000000000 ifHCInOctets.25 = 0x000000000 ifHCInOctets.26 = 0x0001a7afc !! This is serial interface 6/0/1:0 ifHCInOctets.28 = 0x0001a7370 !! This is serial interface 6/0/2:0 ifHCInOctets.34 = 0x00006a45a !! This is serial interface 6/0/3:0 ifHCInOctets.36 = 0x000051cb0 !! This is serial subinterface 6/0/2:0.1 ifHCInOctets.37 = 0x00004526e !! This is serial subinterface 6/0/3:0.1
Enabling Only Slower Frame Relay Subinterfaces for 64-Bit Interface MIB Counters Example
In the following example, the frame-relay ifmib-counter64 command is used with the subif keyword to enable subinterfaces that are associated with serial interfaces 6/0/1:0, 6/0/2:0, and 6/0/3:0 to be included in the 64-bit interface MIB counters. Slower main interfaces are not included. The example also shows the corresponding statistics for the 64-bit interface MIB counters.
interface Serial6/0/1:0 ip address 1.1.1.1 255.255.255.0 encapsulation frame-relay no ip route-cache cef no ip route-cache frame-relay interface-dlci 101 no frame-relay inverse-arp frame-relay ifmib-counter64 subif interface Serial6/0/2:0 no ip address encapsulation frame-relay no ip route-cache cef no ip route-cache no frame-relay inverse-arp frame-relay ifmib-counter64 subif interface Serial6/0/2:0.1 point-to-point ip address 2.1.1.1 255.255.255.0 no ip route-cache frame-relay interface-dlci 201 ! interface Serial6/0/3:0 ip address 3.1.1.1 255.255.255.0 encapsulation frame-relay frame-relay interface-dlci 301 no frame-relay inverse-arp frame-relay ifmib-counter64 subif interface Serial6/0/3:0.1 point-to-point ip address 3.1.2.1 255.255.255.0 frame-relay interface-dlci 302
The following example shows corresponding sample output for the show frame-relay pvc command with the 64-bit keyword. Note that the frame-relay ifmib-counter64command does not affect the output of the show frame-relay pvc command.
Router# show frame-relay pvc 101 64-bit DLCI = 101, INTERFACE = Serial6/0/1:0 input pkts 231 output pkts 228 in bytes 23604 out bytes 23502 Router# Router# show frame-relay pvc 201 64-bit DLCI = 201, INTERFACE = Serial6/0/2:0.1 input pkts 1453 output pkts 1408 in bytes 335024 out bytes 327272 Router# Router# show frame-relay pvc 301 64-bit DLCI = 301, INTERFACE = Serial6/0/3:0 input pkts 510 output pkts 508 in bytes 52690 out bytes 52622 Router# Router# show frame-relay pvc 302 64-bit DLCI = 302, INTERFACE = Serial6/0/3:0.1 input pkts 957 output pkts 912 in bytes 283246 out bytes 275493
The following output from an SNMP inquiry shows that the 64-bit interface MIB counters include the subinterfaces configured above:
ifHCInOctets.5 = 0x000000000 ifHCInOctets.16 = 0x000000000 ifHCInOctets.17 = 0x00337a158 ifHCInOctets.18 = 0x000000000 ifHCInOctets.19 = 0x000000000 ifHCInOctets.20 = 0x000000000 ifHCInOctets.24 = 0x000000000 ifHCInOctets.25 = 0x000000000 ifHCInOctets.36 = 0x000051cb0 !! This is serial subinterface 6/0/2:0.1 ifHCInOctets.37 = 0x00004526e !! This is serial subinterface 6/0/3:0.1
