What is the switching performance?

Packet switching capacity is 136 Gbps with 264 Gbps aggregate throughput and 101 Mpps Layer 2/3 forwarding rate. This enables wire-speed performance for 64-byte packets, supporting high-volume traffic in access or aggregation roles.

Does it support stacking?

Yes, Virtual Chassis technology interconnects up to 10 units over a 128 Gbps backplane, managed as a single logical switch. This provides scalability for expanding networks without proportional management overhead.

What management interfaces are available?

Features web-based GUI, CLI, SNMP, and Junos Space Network Director. These tools enable comprehensive configuration, monitoring, and automation for enterprise IT teams handling Layer 2/3 operations.

What are the physical and power specs?

1U rack-mountable at 440 x 438 x 43 mm, 6.4 kg weight. Hot-swappable 190W AC (320W PoE) supplies with 100-240V autosensing, field-replaceable fans, operating 0-40°C and 5-85% humidity for reliable deployment.

What Layer 2/3 features does it offer?

Supports 32,000 MAC addresses, 4,096 VLANs, 9,216-byte jumbo frames, and L3 protocols including OSPF, BGP, RIPv2, IPv6. Also includes link aggregation with 64 LAGs up to 8 ports each for resilient, high-capacity networking.
