How to match tftp traffic in CoPP

I am trying to configure CoPP on my 7200 router. Everything works fine, but when I try to download IOS via TFTP, the TFTP keeps dropping off.

I tried to use the below access-list to match TFTP traffic but it does not work. Is TFTP using different port for DATA and control traffic like FTP? Anyone could help?

60 permit udp 210.18.250.0 0.0.1.255 any eq tftp

70 permit udp 210.18.250.0 0.0.1.255 eq tftp any

Thanks

Re: How to match tftp traffic in CoPP

You are right.

TFTP uses high udp ports for the data so they won't be matched there.

Can you try matching on source and destination to see if it helps?
