Nor does it work on a Cisco 7609 10G interface running IOS 12.2(33)SRB2:

UA-004-R1(config)#int te2/1.1702
UA-004-R1(config-subif)#ip multicast ?
  boundary       Boundary for administratively scoped multicast addresses
  helper-map     Broadcast to Multicast map OR Multicast to ip-address map
  limit          Limit multicast mroute state
  rate-limit     Rate limit multicast data packets
  ttl-threshold  TTL threshold for multicast packets

UA-004-R1(config-subif)#ip multicast rate-limit in group-list SAP-mcast-group 1000
 "ip multicast rate-limit" command is not supported
UA-004-R1(config-subif)#

Not sure about JunOS, but I believe this should do the trick for  
Cisco
IOS:

ip access-list standard SAP-mcast-group
permit host 224.2.127.254
deny any any
exit

interface X/Y.Z
ip multicast rate-limit in group-list SAP-mcast-group 1000
exit

This should be applied at (interfaces facing) the edges of your
multicast network. It effectively means that any sources the router
sees with a rate exceeding 1000 kbps, it will not forward downstream.
        
This doesn't work in 12.2(18)SXF11 on a POS interface.  Any other  
suggestion?
      
I don't know what platform you tried it on, but I've only tested it on  
software-based routers: 7301 (running 12.4T), 7204 VXR (12.3T).  
Therefore I'm not sure if it's the hardware platform that doesn't  
support it (I wouldn't be suprised if it doesn't work on GSRs or  
specific line cards) or if you need a different IOS train.

I'd need to look it up in IOS documentation...
