GIGACORE v1.5.1
This release introduces new features, improvements, and bug fixes.
Applicable Models:
GigaCore 10i, 16i, 30i, 10t, 16t, 18t, 20t.

New Features
Clock Replication Mode
The “Replicate” option is now available as a Clock mode in Group settings. This
mode replicates the boundary clock configured on another Group or one that
originates from the gPTP clock.
This feature enhances support for the recently introduced PTPv2 boundary
clock capabilities, making GigaCore an ideal solution for broadcast and other
applications using protocols like RAVENNA/AES67 and ST2110 in red/blue
redundant setups.

MultiLinkX
MultiLinkX allows you to aggregate up to 8 ports to increase available bandwidth
and throughput, supporting applications with higher bandwidth requirements.
When enabled, trunk connections to neighboring switches will aggregate
automatically. Each switch can support up to 6 distinct link aggregations.

IGMP Fast Leave
When editing a Group, you’ll now see a new checkbox labeled “Fast Leave” in the
IGMP settings. This option quickly frees up bandwidth when devices no longer
need to receive certain multicast streams and no other devices on that link have
registrations to those streams.

Improvements
MLD (IPv6 Multicast Listener Discovery)
IPv6 MLD is now supported by default on GigaCore. MLD snooping can be disabled
along with IGMP snooping by unchecking the IGMP snooping checkbox. As
IPv6 adoption grows, this feature enables GigaCore to manage multicast traffic
effectively for those applications, preparing it for scalability.

Bug Fixes & Stability Improvements
Dante Packet Handling
Resolved an issue where certain Dante packets were processed by the CPU instead
of through hardware, improving network performance.

Known Limitation
Boundary Clock Performance
During an RSTP topology change, boundary clock performance may be affected if
many different clocks (4 or more, depending on the application) are running over
the same trunk connection. This is expected to improve in a next firmware release.
