Is it matching the first class map.  We know for sure that should work.  If
that is not working possibly FPM is not working on the platform.

 

I am guessing your string will be *FFFF* as the size is 1500 and FFFF is not
1500 bytes.

Subject: [OSL | CCIE_Security] FPM with ICMP

 

Hi all

 

I am trying to block "ping 10.20.30.40 data FFFF" from a router.

 

class-map type access-control match-any ac
 match start ICMP payload-start offset 0 size 1500 string "FFFF"
class-map type stack match-all sc
 match field IP protocol eq 1 next ICMP

 

policy-map type access-control ac
 class ac
   drop

policy-map type access-control st
 class sc

service-policy ac

 

It's simple but I am missing something. I am still able to ping.


 

 

With regards

Kings
