What is the switching capacity and performance?

Provides 128 Gbps non-blocking switch fabric bandwidth and 95.2 Mpps forwarding rate, with jumbo frames up to 9,216 bytes. Supports 128 trunks (8 members each), 8 QoS queues/port, and 4,094 VLANs, ensuring line-rate throughput for demanding enterprise applications.

What Layer 3 capabilities does it offer?

Layer 3 aggregation with 12K IPv4 LPM entries, 6K IPv6 LPM, and 32K MAC table (16K L2). Runs protocols like OSPF, BGP, multicast, plus policy engine with 3072 rules (2048 L3/L4), enabling efficient routing in small cores or edge setups.

What management features are included?

Powered by ExtremeXOS 12.4 with serial console, Ethernet management port, and advanced policy support: 250 rules/profile up to 63 profiles. Includes rate limiting (64Kbps granularity, 2048 limiters) and 2,048 ACLs for comprehensive control and monitoring.

Is redundant power supported?

Yes, compatible with optional redundant EPS-500 external power supply via dedicated connector. Also supports EPS-LD (45019), enhancing reliability for 24/7 operations in aggregation or POP environments without single points of failure.

What protocols ensure resiliency?

Supports RFC 3619 EAPS/EAPSv2 for sub-second failover, IEEE 802.1Q VLAN, 802.3ad LACP for link aggregation, and Extreme Standby Router Protocol (ESRP). These provide robust protection against outages in high-availability enterprise networks.
