What is the maximum switching capacity and how does it compare to other enterprise switches?

The Summit X460-48t provides 328 Gbps aggregated switching bandwidth with 166.7 Mpps forwarding rate, delivering non-blocking, wire-speed performance across all 48 Gigabit ports. This capacity supports high-density data center deployments where multiple servers and storage systems require simultaneous, full-rate connectivity without performance degradation.

Can this switch support 10 Gigabit Ethernet uplinks?

Yes. Slot A supports optional two-port 10GbE modules for 20 Gbps uplinks, while Slot B accommodates optional four-port 10GbE for 40 Gbps uplinks. This modular design allows customers to upgrade uplink capacity without replacing the entire switch, providing future-proof scalability.

What PoE+ capabilities does the X460-48t offer?

The X460-48t supports flexible IEEE 802.3at PoE+ with up to 30 Watts per port. With dual hot-swappable AC power supplies, the total PoE+ budget reaches 760 Watts, enabling simultaneous powering of 25+ high-power devices. This supports converged voice, video, and data applications on a single infrastructure.

How many VLANs and ACL rules does this switch support?

The switch supports 4,094 VLANs (Port, Protocol, IEEE 802.1Q) and 4,192 ingress plus 512 egress ACL rules with meters and counters per 24-port. This extensive capacity enables complex network segmentation, multi-tenant isolation, and granular security policies required in enterprise data centers.

What stacking options are available for high availability?

The X460-48t supports SummitStack 40 Gbps or SummitStack-V80 80 Gbps high-speed stacking via optional Slot B modules, plus SummitStack-V for longer-distance stacking. These options enable redundant, fault-tolerant architectures with simplified management of multiple switches as a single logical unit.

What is the latency performance and why does it matter?

The X460-48t achieves less than 4 microseconds latency for 64-byte frames, ensuring low-jitter performance critical for real-time applications, financial trading systems, and time-sensitive workloads. This sub-4µs latency combined with 9216-byte jumbo frame support optimizes both small-packet responsiveness and large-flow throughput.

Is this switch suitable for virtualized data center environments?

Yes. The X460-48t is purpose-built for virtualized data centers with ExtremeXOS Network Virtualization (XNV) for VM inventory and provisioning, Direct Attach capability to offload VM switching from servers, and high-capacity Layer 2/3 scalability. It supports intra-rack and cross-rack stacking with industry-leading flexibility for dynamic VM mobility.
