Hello experts. I am doing more research on packet fragmentation. I want to avoid my routers doing packet fragmentation themselves and leave it to hosts. In a test environment i have configured it as such that the router is responsible for fragmenting the packets to get over its outside link rated at 1400 MTU. The host doesn't know to fragment yet so it gets to router and is too large so it must fragment. I have verified i am up to this point by setting access lists with the fragments keyword. Inside interface of the router that must fragment shows 0 hits on the fragments ace. On the next hop router
the incoming fragments ACE does show fragments, indicating that the router is fragmenting,
My question is as follows: How do i determine how many packets the router has had to fragment itself? I would think this would be an option but don't see a way to view this. Already looked into:
1. show ip traffic: This does increment but it shows all fragments that have flowed through not how many the router had to generate.
2. show controllers fa0/1: This always stays at 0
