Ruijie RG-S6250-48XS8CQ 48×10G SFP+, 8×100G QSFP28 Uplinks

Q1: What port configurations does the RG‑S6250‑48XS8CQ offer?

A: The RG‑S6250‑48XS8CQ model provides 48 × 10 GE SFP+ ports and 8 × 100 GE QSFP28 ports, where each 100 GE port supports 40/100 GE auto-negotiation.

Q2: Does the RG‑S6250 support redundancy features like VSU?

A: Yes. It supports Virtual Switch Unit (VSU) 2.0, allowing two switches to operate as one logical unit, with fast failover (50–200 ms), and supports cross-device link aggregation (M‑LAG).

Q3: Is the power and cooling design redundant?

A: Yes. It includes two hot-swappable power supplies (1+1 redundancy) and four fan modules (3+1 redundancy) to ensure continuous operation.

Q4: What is the switching capacity and forwarding rate?

A: The RG‑S6250 offers up to 2.56 Tbps switching capacity and can forward at roughly 1,920 Mpps.

Q5: Which virtualization and overlay protocols are supported?

A: It supports VXLAN overlay with EVPN and hardware-based segmentation, as well as features like REUP, Graceful Restart, BFD, and Virtual Switch Unit virtualization.

Q6: What data center features are included?

A: Features include REUP, GR, BFD, M‑LAG, VSU, VXLAN/EVPN, advanced buffering for burst flows, and lossless Ethernet support (PFC + ECN).

Q7: Does it support both IPv4 and IPv6 routing?

A: Yes. It supports full IPv4 routing (static, RIP, OSPF, IS‑IS, BGP4) and IPv6 routing (static, RIPng, OSPFv3, BGP4+), plus tunnelling (ISATAP, auto, etc.).

Q8: What security mechanisms are available?

A: Security features include hardware ACLs, DoS protection, IP spoofing prevention, RADIUS/TACACS+, SSH/SNMPv3, ARP anti-spoofing, uRPF, DHCP snooping, BMC support, and port-time based controls.

Q9: How is this switch managed and monitored?

A: It supports management via console, MGMT Ethernet, USB, Telnet, SSH, SNMPv1/v2/v3, NetConf, Python, Span/RSPAN/ERSPAN, syslog, NTP, telemetry, ZTP, and USB logging.

Q10: Does the RG‑S6250 support DAC and optical cables?

A: Yes. SFP+ ports support DAC and optical modules; QSFP28 ports support both 100 GE and 40 GE DAC.

Q11: What are the environmental and physical specs?

A: Operating temp is 0–45 °C, storage −40–70 °C, 10–90% RH, 1RU, weight ~8 kg, AC 100–240 V or DC support, power <300 W.

Q12: Does it support lossless Ethernet for RDMA?

A: Yes, it supports PFC + ECN for lossless Ethernet and zero packet loss during RDMA traffic.

Q13: How does link redundancy work?

A: It supports M‑LAG across devices, REUP for dual uplink protection, Graceful Restart, and BFD for fast convergence.

Q14: Can it integrate into overlay/data center fabric?

A: Yes, with VXLAN/EVPN support it fits overlay fabrics; comes with overlay + hardware-based segmentation.

Q15: What network visibility tools are built-in?

A: It offers advanced telemetry, gRPC, sFlow, SPAN, buffer monitoring, and hardware telemetry for deep visibility and analytics.
