Applying Layer 2 Policers to Gigabit Ethernet Interfaces
To rate-limit traffic by applying a policer to a Gigabit Ethernet
interface (or a 10-Gigabit Ethernet interface [xe-fpc/pic/port]), include the layer2-policer statement with the
direction, type, and name of the policer:
[edit interfaces ge-fpc/pic/port unit 0] layer2-policer { input-policer policer-name; input-three-color policer-name; output-policer policer-name; output-three-color policer-name; }
The direction (input or output) and type (policer or three-color) are combined into one statement and the policer named must be properly configured.
One input or output policer of either type can be configured on the interface.
Examples: Applying Layer 2 Policers to a Gigabit Ethernet Interface
Apply color-blind and color-aware two-rate TCM policers as input and output policers to a Gigabit Ethernet interface:
ge-1/0/0 {
unit 0
layer2-policer {
input-three-color trTCM1-cb; # Apply the trTCM1-color-blind policer.
output-three-color trTCM1-ca; # Apply the trTCM1-color-aware policer.
}
}
Apply two-level and color-blind single-rate TCM policers as input and output policers to a Gigabit Ethernet interface:
ge-1/0/0 {
unit 1
layer2-policer {
input-policer two-color-policer; # Apply a two-color policer.
output-three-color srTCM2-cb; # Apply the srTCM1-color-blind policer.
}
}
Apply a color-aware single-rate TCM policer as output policer on a Gigabit Ethernet interface:
ge-1/0/0 {
unit 2
layer2-policer {
output-three-color srTCM3-ca { # Apply the srTCM3-color-aware policer.
}
}
