Question

What are the supported QoS features for the 16-port 10-Gigabit Ethernet MPC and 100-Gigabit Ethernet MPC?

Answer

The Gigabit Ethernet MPCs supports the following QoS functionality:

 

- Port-based queuing

  • Per-port shaping
  • Eight queues per port
  • 100 ms of delay buffer by default per port
  • 200 ms of delay buffer configurable per port
  • Ability to oversubscribe the delay buffer beyond 200 ms per port

- Queue-level shaping and guaranteed rate

  • Separate guaranteed and shaping rates
  • Rate limit option to police a queue to act as a Low Latency Queue (LLQ)

- Four WRED profiles per queue

- Multiple queue priority levels

 

- Strict High, High, Medium, and Low guaranteed priority levels

  • Strict High and High are at the same hardware priority level
  • Round robin at each guaranteed priority level

     

 - High and Low excess priority levels

  • Queues perform WRR at the excess priority levels
  • Strict priority scheduling at each excess priority level

- Classification per VLAN

  • MPLS EXP
  • IPv6, IPv4 ToS
  • Inner and outer tag 802.1p (and DEI7)
  • MF classifiers per VLAN

- Policers per VLAN

  • Single rate, single-rate tricolor marking, two-rate tricolor marking, hierarchical policers
  • Class-aware intelligent hierarchical policers
  • Physical interface policers

 - Rewrites per VLAN

  • MPLS EXP, IP DSCP/PREC
  • Inner and outer tag 802.1p (and DEI7)
  • Ingress DSCP rewrite
