Most of production environment has nice monitoring tools that provides nice GUI based stats and information. Actually, you can see protocol stats thru Cisco router. It might be useful tips, when you are deploying QoS policy or bandwidth optimization.
1. NBAR(Network Based Application Recognition) has to enable "ip nbar protocol-discovery" on the interface
Cisco-NBAR(config)# interface serial1/0
Cisco-NBAR(config-if)# ip nbar protocol-discovery
2. Monitoring protocol stats by top-n
Cisco-NBAR# sh ip nbar protocol-discovery top-n 5
Serial1/0
Input Output
----- ------
Protocol Packet Count Packet Count
Byte Count Byte Count
5min Bit Rate (bps) 5min Bit Rate (bps)
5min Max Bit Rate (bps) 5min Max Bit Rate (bps)
