Debug netdr capture rx
show netdr capture-packets
For Netdr file export in this link and find top talker
Note : UDP packet not showing into the buffer it mean some thing wrong
Note : process switched packets are stored in public buffer pools.
CEF enable or not:
Show ip cef summary
Show ip interface
if ip verify unicastincrease FIB TCAM utilization
Commands to verify the FIB TCAM utilization:
show mls cef maximum-routes
show mls cef summary
Config )#mls cef maximum-routes <protocol> <#entres)
ACL Merge Algorithm:
Which entry hardware switch and which software switch
show fm summary
show tcam count >>used and free
command to change ACL merge algo:
config)#mls aclmerge algorithm ?
bdd...Binary
odm...Order
Config)#mls aclmerge odm optimizations <--hidden
HW rate-limiters:
configure how many pps max can leak from the PFC to RP CPU via special built-in
show mls rate-limit
config)#mls rate-limit?
Netflow data export:
Netflow is handled in HW on PFC. it has its own netflow TCAM.
