As is shown in the information you suggest below ARP and PPPoE are the two
exceptions to the rule of "not allowed to use match protocol"

You can use FPM but that is limited to CoPP only :-)

For control plane you can't use NBAR i.e., using match protocol

Features that require Network-Based Application Recognition (NBAR)
classification may not work well at the control plane level. The following
classification (match) criteria are supported on all platforms: 

.Standard and extended IP access lists (ACLs). 

.In class-map configuration mode: match ip dscp, match ip precedence, and
match protocol arp, and match protocol pppoe commands.

And it just occurred to me. Let's say I want to filter all BPDU traffic from
switches connected to the router. Just theoretically.

"match protocol bpdu" doesn't exist. Does it mean that I can't filter BPDU
with CPPr whatsoever ?

Hi all

I want to drop ARP and CDP packets coming to router using control plane
cef-exception interface. 

As you may be aware that CPPr doesn't support class maps with protocol
recognization i.e., using "match protocol"

I am not able to find options to define an ACL for CDP and ARP. 

Any thoughts?



With regards
Kings
