The DM4270 family of switches provides high switching capacity to meet the increasing demands of IP traffic aggregation in metro ethernet networks, high-capacity enterprise networks and top-of-rack datacenter applications, always providing high performance and reliability.
Based on the DmOS network operating system, the DM4270 switches ensure robustness and high availability services on a platform with support for a number of L2, L3 and MPLS functionalities, among which stand out MPLS L2VPN and L3VPN applications support. All packet forwarding, ACL filtering and QoS policies are done in HW, ensuring wirespeed operation.
The switches have 1U height and are ready for 19 inches standard rack installation. Both models have two hot swappable slots for redundant AC or DC universal power source units, assuring high availability services and operation.
