WRR and Strict Priority on Cisco Catalyst 4500E Series

[apereira3]

Hi all,

The Cisco Catalyst 4500E Series switches implements Weighted Round Robin (WRR) and Stric Priority (SP) features for QoS?

This platforms also performs the combination between WRR and SP (WRR+SP) per interface?

Can you help me please?

Thank you!

4500 QoS depends on the sup model.  I believe most that support QoS also support a PQ feature.  Beyond that, you would need to reference the specific sup's QoS features.  The older sups have some interesting QoS prioritization.  I think I recall only some 4500 sups support FRED and DBL too.

Hi Joseph,

Thank you for your reply! I refer to supervisor engine 7L-E. This supervisor supports the Weighted Round Robin (WRR) feature? And combination of PQ feature?

Thank you!
