Monitor QoS Policy on Cisco Router using SNMP

March 23rd, 2017 No comments

This recipe describes how to use SNMP to determine the traffic offered and drop rate for a QoS policy configured on a Cisco router.

The steps here describe which OIDs to interrogate in the CISCO-CLASS-BASED-QOS-MIB

STEP 1:

Get the SNMP ifIndex for the interface where the QoS policy is attached:
CiscoRouter#sh snmp mib ifmib ifindex | i GigabitEthernet0/1
GigabitEthernet0/1: Ifindex = 22

(or by using SNMP):
root@Linux# snmpwalk -v2c -c communityname 10.0.200.12 1.3.6.1.2.1.2.2 | grep -i GigabitEthernet0/1
RFC1213-MIB::ifDescr.22 = STRING: “GigabitEthernet0/1” Read more…

July 22nd, 2009 No comments

MIB stands for Management Information Base and is a collection of information organised into a hierarchy. These are accessed using a protocol such as SNMP. There are two types of MIBs: scalar and tabular. Scalar objects define a single object instance whereas tabular objects define multiple related object instances grouped in MIB tables. Read more…
