Wireshark – Identify bursty traffic on a Cisco switch

If a switch port has a high number of output packets being dropped, it could be that the amount of traffic being sent is higher than the what the interface is capable of handling, i.e traffic is coming into the switch on a gigabit interface but trying to leave on a fastethernet port, or the traffic is very bursty, the article below will show how to setup Wireshark to identify if the traffic is bursting. It may be the case that the egress buffer may need to be increased on the egress interface.
