This applies the same CLP-1-first selective discard logic to the non-real-time VBR queue instead of CBR or VBR-RT. Applied to non-real-time VBR traffic, this threshold can typically be set more permissively than its real-time counterparts since NRT traffic, like bursty data, is inherently more tolerant of queue delay than CBR or VBR-RT circuits sharing the card. For example, an admin sets cardClp0VbrNrtThreshold noticeably higher than the VBR-RT and CBR thresholds on the same card, since non-real-time data traffic can absorb more queue buildup before it needs protecting via selective discard.
