Table 7: Two-Color Policer Configuration and Application Overview

Policer Configuration
Single-Rate Two-Color Policer
Defines traffic rate limiting that you can apply to Layer 3 protocol-specific traffic at a logical interface. Can be applied as an interface
policer or as a firewall filter policer.
Basic policer configuration:
[edit firewall]
policer policer-name {
if-exceeding {
bandwidth-limit bps;
burst-size-limit bytes;
}
then {
discard;
forwarding-class class-name;
loss-priority supported-value;
}

single-rate two-color policers to Layer 3 traffic. For information about applying single-rate
two-color policers to Layer 2 traffic, see

Layer 3 Application
Method A—Apply as an interface policer at the
protocol family level:
[edit interfaces]
interface-name {
unit unit-number {
family family-name {
policer {
input policer-name;
output policer-name;
}
}
}
