The Configuration Guide for 9920 version 21.2.2.0 provides
detailed instructions for configuring and managing the network packet broker (NPB) features of
the Extreme 9920 platform. Key areas include link aggregation, replication, load balancing, and
advanced packet-handling techniques such as packet slicing, ACL filtering, and header
modification. Tunnel origination and termination for IPv4/IPv6, QoS configurations for traffic
prioritization, and encapsulation using VLAN, VXLAN, and GRE are addressed. Configuration
management tasks, including saving, applying, and viewing configuration files, along with port
management and packet capture for traffic analysis, are covered in depth. CLI commands are
emphasized for efficient setup, control, and troubleshooting in complex, high-performance
network environments.
