Aviz Networks details APB 2.11 support for 400G, GRE and ZTP

Aviz Networks released APB 2.11, adding 400G platform support, Generic Routing Encapsulation (GRE) tunneling for routed traffic, enhanced ONIE Zero-Touch Provisioning (ZTP), and Command-Line Interface (CLI) usability updates that affect deployment and monitoring in enterprise and service provider networks.

Research Overview

APB 2.11 focuses on scaling packet-brokering functions to support higher-throughput fabrics, routed traffic transport, and automated device onboarding. The release targets deployments from edge aggregation to 400G cores where traffic volume and distributed observability requirements intersect.

Key findings

The update adds compatibility with Celestica DS4000 and Dell 5212 platforms, enables GRE encapsulation for Layer-3 mirrored traffic, extends ONIE-based ZTP, and expands CLI capabilities for output handling and scripting. These changes enable mirrored traffic to be moved across IP networks while reducing manual provisioning steps.

Technical breakdown

Platform support

Support for Celestica DS4000 brings a 1U option with 32 QSFP-DD 400GbE ports and up to 12.8 Tbps switching capacity along with flexible port breakout. The DS4000 implementation includes Test Access Points (TAP) and Switched Port Analyzer (SPAN) aggregation, L2-L4 filtering, traffic distribution controls, and port- and flow-level statistics.

Dell 5212

Dell 5212 support provides equivalent packet-brokering features aimed at enterprise and edge locations and adds Virtual Extensible LAN (VXLAN) and GRE encapsulation options plus packet truncation to reduce monitoring bandwidth. The device supports the same filtering and distribution mechanisms validated on the DS4000 platform.

Encapsulation and provisioning

GRE encapsulation on Broadcom Trident3-based systems preserves Virtual LAN (VLAN) tags and metadata while transporting mirrored traffic over routed networks, enabling centralized analysis of dispersed TAPs. ONIE ZTP enhancements use Dynamic Host Configuration Protocol (DHCP) options to retrieve an APB-NOS image or provisioning script and support CLI-initiated image uninstall on the next reboot to automate initial software loading.

CLI enhancements

CLI updates add pagination, command sorting, pipes such as grep and tail, and interface range commands to streamline output review and bulk operations. The command additions support common operator workflows for inspection and configuration tasks.

Product update

APB 2.11 broadens deployment choices across data center aggregation and edge sites, validating Broadcom-based platforms for packet-brokering roles and supporting monitoring, analytics ingestion, and security enforcement use cases. The release packages encapsulation, provisioning, and user interface changes in a single software update.

Operational impact

GRE tunneling reduces the need for dedicated physical aggregation links by carrying mirrored traffic over IP paths, while ONIE ZTP automates image delivery to reduce manual installation steps. CLI improvements provide operators with improved tools for reviewing large outputs and performing batch changes.

APB 2.11 combines expanded 400G hardware support, routed traffic encapsulation, automated provisioning, and CLI feature additions to broaden deployment and monitoring options for data center and service provider networks. This “Blog Signals brief” is a fact-based summary of the vendor blog.
