Configuring The Ingress Metering; Ingress Metering (Policing) - Allied Telesis SwitchBlade x3100 Series Manual

Introduction

6.5 Ingress Metering (Policing)

To provide metering (policing) of ingress traffic, classifiers are defined and then associated with a RATE (the
CIR) and BURSTSIZE (the CBS). The actions that are then taken when the traffic exceeds the profile is DROP
or FORWARD the packets. The NCCOUNT option allows for counting non-conforming packets.
Once the CLASSIFIER(s) are associated with a meter and an interface, the system may generate a warning mes-
sage at the user's CLI session stating that classifier capacity or capabilities have been exceeded on the slot(s)
impacted by the provisioning change. The user should investigate classifier-related provisioning, such as IGMP,
DHCPRELAY, VLAN (for per-VLAN UFO and HVLAN), EPSR, INTERFACE (TAGALL option for HVLAN),
ACCESSLIST, and CLASSIFIER to determine the reason for the message.
Table 6-8 lists the ingress increment value and burst size support when configuring the interfaces.
