Generic VLAN Registration Protocol (GVRP)/Generic Attribute Registration Protocol (GARP): Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS Private VLAN Edge (PVE), also known as protected ports, with multiple uplinks Support for up to 256 VLANs simultaneously (out of 4096 VLAN IDs) Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP) Multiple Spanning Tree instances using 802.1s (MSTP) Jumbo Frames: up to 10 KB supported on 10/100 and Gigabit interfacesįast convergence using 802.1w (Rapid Spanning Tree ), enabled by default Switching Capacity in Gigabits per Second (Gbps): 12.8Ĭapacity in Millions of Packets per Second (mpps) with each packet being 64-bytes: 9.52 QoS: Priority levels 4 : hardware queues, Scheduling: Priority queuing and weighted round-robin (WRR), Queue assignment based on DSCP and class of service (802.1p/CoS).Ģx RJ-45 + SFP Gigabit Ethernet Combo PortsĢ4x RJ-45 Fast Ethernet Power Dedicated: 180W Layer 3: IPv4 routing Wirespeed routing of IPv4 packets, Up to 32 static routes and up to 32 IP interfaces, Classless Inter-Domain Routing (CIDR) support for CIDR.
