Aviz Networks details Packet Broker 2.12.1

Aviz Networks has released Aviz Packet Broker 2.12.1 with support for dual-rate transceivers, hardware-based packet length filtering, and expanded sFlow controls. The update is aimed at simplifying optical setup, traffic selection, and monitoring in data center networks. ## Product Update Aviz Packet Broker 2.12.1 adds native dual-rate transceiver support for compatible Broadcom platforms. The software uses RS0 and RS1 register controls to let optics operate at 1G or 10G, and a background service restores the configured mode after reinsertion. The release also keeps dual-rate settings in the system configuration, so they remain in place after reboots, service restarts, and hardware replacement events. On Broadcom Trident and Tomahawk platforms, packet length filtering is handled in hardware at wire speed. ## Technical Breakdown Operators can set length-based rules to allow or block traffic based on packet size. The release cites use cases that include dropping jumbo frames from monitoring streams, forwarding control-plane traffic, filtering fragmented or undersized packets, and mirroring larger application flows. These length rules can be combined with filters based on IP address, VLAN, protocol, DSCP, and transport port. Aviz also added CLI controls for sFlow sampling direction at the global or interface level. ## Operational Impact The sFlow update allows ingress, egress, or bidirectional sampling, depending on platform support. Teams can also turn sFlow on or off for individual interfaces while keeping interface-specific settings intact. Aviz says the polling interval changes are meant to simplify ongoing management. The company frames the release as a way to improve optical flexibility, traffic visibility, and monitoring control in modern data center environments.
