I'm looking for specific information regarding the Errors In & Errors Out optional channels within the SNMP Traffic Sensor. I have a need to monitor the Input, Output, CRC, and Frame error interface statistics. I would prefer to not have to create custom OID & template for 3000 uplink ports, so it would be nice to know; 1) Is this functionality already built in? 2) If yes, is there an easy way to add Errors In / Out channels without recreating the sensor & loosing the historic monitoring? 3) If no, what is the best approach for adding all Trunk Ports on a Router/Switch that include; Traffic In/Out, Discards In/Out, & the Interface Errors that I need?
