This document describes how to perform Simple Network Management Protocol (SNMP) Walk for Serial Interface Utilization on Cisco Routers.
Cisco recommends that you meet these requirements before you attempt this configuration:
Server from where you are polling the router is reachable
Correct read-write SNMP community configured on the router
This document is created using a Cisco 1941 router with VWIC2-1MFT-T1/E1. However, this document is not restricted to specific software and hardware versions.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
This document helps a technician to understand why SNMP walk to poll Serial Interface Utilization using ifHCInOctets and ifHCOutOctets does not work and what is the workaround in such situations.
