You haven't mentioned how you are testing the rate limit, or what type of traffic you are trying to rate limit?
What you have configured there is a RACL which will apply to traffic received from vlan 1 if and only if it is being routed via the vlan.1 RVI (in other words, destined for an IP address NOT in that VLAN) - if this is what you are trying for does vlan.1 have an IP address?
If you are trying to rate-limit all ingress traffic into VLAN 1 from any port, to any other port, you will need to change your configuration to make it a VACL:
set firewall family ethernet-switching filter udp-rate-limit
...
set vlans v1 filter input udp-rate-limit
Hope this helps
