What is the latency and frame support?

Latency is less than 4 microseconds for 64-byte packets. It supports Jumbo Frames up to 9216 bytes, ideal for storage and high-throughput applications, with 176 Gbps switch fabric and up to 448 Gbps aggregated bandwidth.

How many MAC addresses and VLANs does it support?

Up to 512K MAC addresses for scalable Layer 2, and 4,094 VLANs including Port, Protocol, and IEEE 802.1Q types. This enables large-scale segmentation without performance degradation.

What management options are available?

Out-of-band 10/100/1000BASE-T port and RS-232c serial port for management. ExtremeXOS supports advanced protocols like 128 load-sharing trunks and 8,192 ingress ACL rules.

What is the physical form factor and power specs?

1RU fixed configuration, 1.73 inches (4.4 cm) height, with field-replaceable fan tray. Voltage: 100-240V 50/60Hz 4.0A; current: 2.0-2.3A low-line, 0.9-1.0A high-line; heat: 675-692 BTU/hr.
