Key Features:

• Smart Managed with Layer‑2 + static Layer‑3 routing: Includes VLANs, IGMP snooping, STP/RSTP/MSTP, and static routing to route traffic between VLANs without an external router.
• PoE Support (select models): IEEE 802.3af/at (PoE/PoE+) options for powering IP cameras, access points, and VoIP devices; PoE budget varies by model (e.g., up to 130 W on DGS‑1210‑10MP).
• Fiber uplink ports: Combo or dedicated SFP ports for 1 Gbps fiber connectivity to extend networks over longer distances.
• Auto Voice VLAN & Surveillance Mode: Auto‑detects VoIP and ONVIF cameras, placing them in separate VLANs with tailored QoS and simplified management interfaces.
• Advanced L2 features: IGMP snooping/v3, link aggregation (LACP), port mirroring, 802.3x flow control, loopback detection, and more.
• Security Enhancements: ACLs, 802.1X port‑based authentication, Safeguard Engine flood/virus protection, DHCP snooping, ARP spoofing prevention.

Key Features:

• Aruba ProVision ASIC: Delivers wire-speed performance and low latency.

• Layer 2 & Basic Layer 3 Routing: Static routing and RIP support.

• Advanced QoS & Security: VLANs, ACLs, traffic prioritization, 802.1X, RADIUS/TACACS+.
• Built-in 10 GbE Uplinks: Improves bandwidth to aggregation/core layers.
• PoE+ Support (Optional): Provides power to APs, IP phones, cameras.
• Management & Monitoring: Web UI, CLI, SNMP, Aruba Central, AirWave.

Key Features:

• High‑Performance Switching: Wire‑speed Layer 2 and Layer 3 forwarding with very low latency for demanding data center traffic.
• Flexible Port Configurations: Options for 10 GbE SFP+/SFP28 access, 10GBASE‑T copper, and 40 GbE QSFP+ uplinks across models like QFX5100‑48S, QFX5100‑48T, QFX5100‑24Q, and QFX5100‑96S.
• Topology‑Independent In‑Service Software Upgrade (TISSU): Enables seamless Junos OS upgrades without disrupting traffic in standalone mode.
• Automation & Orchestration: Zero‑touch provisioning, Python scripting, integration with orchestration tools (VMware NSX, Puppet, OpenStack) and intent‑based networking support.
• Advanced Layer 3 Features: Supports OSPF, BGP, static routes, IPv6, and MPLS capabilities (including L3 VPN, IPv6 6PE).

• Virtualization Support: VXLAN and EVPN for overlay network architectures.

• High Availability/Resiliency: Redundant hot‑swappable power supplies and fans, flexible airflow directions for data center racks, and robust forwarding tables.
