user@switch# set class-of-service interfaces ge-0/0/1 unit 0 classifier dscp1
Specify the number of bits per second permitted, on average, for the firewall policer,
5.
which will later be applied to the LSP:
[edit firewall]
set policer mypolicer if-exceeding bandwidth-limit 500m
Specify the maximum size permitted for bursts of data that exceed the given
6.
bandwidth limit for this policer:
[edit firewall policer]
set mypolicer if-exceeding burst-size-limit 33553920
Discard traffic that exceeds the rate limits for this policer:
7.
[edit firewall policer]
set mypolicer then discard
To reference the policer, configure a filter term that includes the policer action:
8.
[edit firewall]
user@switch# set family any filter myfilter term t1 then policer mypolicer
Apply the filter to the LSP:
9.
[edit protocols mpls]
set label-switched-path lsp_to_pe2_ge1 policing filter myfilter
NOTE: You can also configure schedulers and shapers as needed. See

You can add class-of-service (CoS) components to your MPLS networks on EX Series
switches to achieve end-to-end Differentiated Services to match your specific business
requirements. The configuration of CoS components on the provider switches is the same
regardless of whether the provider edge (PE) switches are using MPLS over CCC or IP
over MPLS.
This task shows how to configure a custom EXP classifier and custom EXP rewrite rule
on the provider switch.
Import the default EXP classifier classes to the custom EXP classifier that you are
