- ACL based
- QoS remarking and remapping for QoS domain translation between a service provider and client networks
- Overriding of each QoS assignment according to the configured priority
|
| Shaping and Scheduling | - 8 queues on each physical port
- Shaping per port, per queue, per queue group
|
| Access Control List | - Ingress and Egress ACL tables

In order to set up port switching on CRS1xx/2xx series switches, check the Bridge Hardware Offloading page.
| Note |
|---|
Dynamic reserved VLAN entries (VLAN4091; VLAN4090; VLAN4089; etc.) are created in the CRS switch when switched port groups are added when a hardware offloaded bridge is created. These VLANs are necessary for internal operation and have lower precedence than user-configured VLANs. |
