What is the switching capacity and forwarding performance?

Delivers 176 Gbps non-blocking throughput with up to 512K MAC addresses and 512K IPv4 routes. Supports 60K ACLs and 1024 centralized classifiers using Layers 1-4, ensuring wire-speed performance for demanding Layer 2/3 operations as specified in Summit X450a Series documentation.

What Layer 3 protocols are supported?

Includes OSPF, VRRP, ESRP (Layer 2/3), and Equal Cost Multipath (ECMP) routing. Additional switching protocols cover IEEE 802.1Q VLAN, 802.3ad LACP, RFC 3619 EAPS/EAPSv2, and Rapid Spanning Tree, enabling robust routing and redundancy per MTMnet datasheet.

How is management performed on this switch?

Supports Web-based GUI, CLI, and SNMP v1/v2/v3 interfaces. Additional features include ExtremeXOS Network Login for user control, RMON (Stats/History), RFC 2925 Ping/Traceroute MIB, and CPU DoS protection with rate-limiting, facilitating comprehensive administration as per MTMnet Summit X450e datasheet.

What redundancy features are available?

Offers optional redundant AC/DC power supplies that are hot-swappable and field-replaceable, plus a redundant fan tray. ExtremeXOS provides high availability with modular OS, preemptive multitasking, and protected memory for carrier-grade operations, detailed in Extreme Networks documentation.

What are the physical and environmental specs?

1RU rack-mount chassis with operating temperature per EN/ETSI 300 019-2-3 Class 3.1e (0-40°C), storage Class 1.2, and transportation Class 2.3 standards. Complies with ASTM D3580 vibration and EN/ETSI 300 753 acoustic noise, suitable for enterprise rack deployments per Extreme technical specs.
