Aviz Packet Broker 2.11 details 400G support and GRE tunneling

Aviz Packet Broker (APB) Release 2.11 expands hardware compatibility to 400G platforms, adds GRE encapsulation to carry mirrored Layer 2 traffic across Layer 3 networks, and refines ONIE zero-touch provisioning and CLI tools for operational management.

Research Overview

The vendor frames Release 2.11 as a response to expanding network visibility demands across data center and service provider deployments, including higher link speeds and distributed architectures. The update focuses on enabling packet brokering at larger scale while reducing manual deployment and improving operator interactions through the CLI.

APB 2.11 adds support for specific Dell and Celestica platforms, introduces GRE tunneling for routed traffic transport, improves ONIE Zero-Touch Provisioning (ZTP) behavior, and updates CLI usability features described as day-to-day operational improvements.

Key Findings

Release 2.11’s hardware expansion adds 400G-capable support for Celestica DS4000 and Dell 5212, with Broadcom-based platform validation stated for APB environments. The release also states GRE encapsulation support for Broadcom Trident3 platforms to preserve VLAN tags and packet metadata when traffic traverses Layer 3 networks.

On deployment and operations, APB 2.11 enhances ONIE ZTP with additional behaviors, and it improves the command-line interface by adding pagination, sorting, pipe operations such as grep and tail, and range commands for interface operations.

Technical Breakdown

Celestica DS4000 support is described as a 1U open data center switch with 32 x 400 GbE QSFP-DD ports and up to 12.8 Tbps switching capacity. The blog states APB 2.11 uses DS4000 for traffic aggregation from TAPs and SPAN ports, L2/L3/L4 filtering for IPv4 and IPv6 traffic, distribution using static or dynamic LAG and hybrid port lookup, and real-time port-level and flow-level statistics.

Dell 5212 support is described as covering features available on DS4000 plus additional capabilities listed as VXLAN encapsulation support and GRE encapsulation support, along with packet truncation intended to optimize bandwidth toward monitoring tools. The blog positions these platforms for different deployment contexts, with DS4000 presented for large-scale leaf-spine and aggregation roles and Dell 5212 presented for enterprise, edge, and campus visibility use.

Operational Impact

GRE encapsulation in APB 2.11 is described as enabling mirrored traffic to traverse Layer 3 networks while preserving VLAN tags and packet metadata. The blog associates GRE tunneling with scalable aggregation from geographically distributed TAPs, reduced physical cabling via virtualized traffic paths, and centralized monitoring and analysis over IP networks.

For provisioning, the blog explains ONIE ZTP behavior as occurring before the network operating system boots and using DHCP to discover a provisioning server. It states that APB 2.11 adds features including CLI-based image uninstall on the next reboot, seamless image loading via DHCP server options, and fully automated onboarding using ONIE’s native discovery mechanism, including download of either an APB-NOS image (.bin) or a provisioning script.

CLI usability improvements are listed as pagination for output readability, sorting across supported commands, pipe operations including grep, exclude, count, no-more, and tail, and range commands for interface operations to simplify bulk management. The blog states these changes reduce operational overhead and improve efficiency for network operators.

APB Release 2.11 combines expanded 400G platform support, GRE encapsulation for routed traffic mirroring with preserved VLAN tags and packet metadata, enhanced ONIE zero-touch provisioning behaviors, and CLI usability updates focused on pagination, sorting, pipe operations, and range commands.
