Filtering IP printing Traffic and its % ( How To )
The following question is kind of a more of HOW TO, and how I would approach gathering this information.
I am trying to find out how to gather only IP printing traffic to ultimately decipher how much printing traffic goes through a specific Fast Ethernet Interface in our catalyst 6500 switch.
We have about 80 printers in one building, lets call it BuildingA-Boston. Print servers are in a centralize remote location buildingB-New-York.
Building-A LAN is designed with Dual-Core architecture using Catalyst 6505 switches as our distributed layer and about 7 4000 series switches for the access layer and their respective VLANS.
The Wide Area is handle by a 7507 Cisco router with a T3 pipe connecting to the remote site for file and print services. Users are complaining of slowness for IP printing services, and of course, they 1st question at the network before they question the servers. Obviously printing will be slower since these services have to go across WAN links instead of having Print-Servers local.
By looking the Fast Ethernet interface on the router I find that it has no problems, and the fast Ethernet average utilization stats reported by Vital-Net is less than 15% with no errors reported.
