rcIngressMirrorDivider
Module: SWITCH-PORTMIRROR-MIB
OID (symbolic): SWITCH-PORTMIRROR-MIB::rcIngressMirrorDivider
OID (numeric): 1.3.6.1.4.1.8886.6.1.4.2.2
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: Receive frames that have passed the ingress mirror filter rule can further be pruned to reduce the overall number of frames returned to the monitor port. Frames that pass the ingress mirror filter rule are further divided by the value that user sets, so that only one in n frames(1/n of frames, where n='value') are mirrored.
What is rcIngressMirrorDivider?
This value, 1 to 1023, sets a sampling divisor so only one in every n frames that pass the ingress mirror filter is actually forwarded to the monitor port. Admins raise it to reduce the volume of mirrored traffic reaching the analyzer on a heavily loaded link, trading full capture for sampled visibility. Setting this to 10 mirrors only one out of every ten matching frames, reducing the load on the monitor port and capture tool.
