Support FS S3410 Series Switches

PICOS 4.4.5.1 release for FS models S3410L-24TF, S3410L-24TF-P, S3410-24TS, S3410-24TS-P, S3410C-16TF, S3410C-16TF-P, S3410C-16TMS-P and S3410C-8TMS-P.

Support IS-IS

IS-IS (Intermediate System to Intermediate System) is an Interior Gateway Protocol (IGP) used within an autonomous system. It is a link-state protocol that employs the Shortest Path First (SPF) algorithm for routing calculations. For more information, see the documentation IS-IS Configuration.

Support OSPFv2/OSPFv3 GR

OSPF Graceful Restart (GR) ensures that routers running the OSPF protocol can maintain normal service forwarding during a primary-backup switchover or an OSPF protocol restart. For more information, see the documentation OSPF GR.

Support IPv6 Source Guard

IPv6 Source Guard is a security feature designed to filter IPv6 traffic on untrusted Layer 2 ports. It helps switches or routers reject traffic originating from addresses not stored in the IPv6 binding table. IPv6 Source Guard discards packets with IPv6 source addresses absent from the binding table, which contains entries for the link-local addresses of hosts. For more information, see the documentation IPv6 Source Guard (IPSG for IPv6).

Support IPv6 DHCP Guard

IPv6 DHCP Guard prevents replies and advertisements from unauthorized DHCP servers and relay agents. It filters DHCPv6 response messages based on criteria such as the source address of the DHCPv6 message, the IPv6 address assigned to the user, or the priority of the DHCPv6 server. This ensures that DHCPv6 clients obtain prefixes, addresses, or other parameters from authorized DHCPv6 servers. For more information, see the documentation DHCPv6 Guard Configuration.

Support IPv6 DHCP Snooping

DHCPv6 Snooping is a security feature that intercepts DHCPv6 messages between DHCPv6 Servers and DHCPv6 Clients. It establishes and maintains a DHCPv6 Snooping binding table that records information about DHCPv6 Clients, including user MAC addresses, IPv6 addresses, lease durations, VLAN IDs, and interfaces. The device uses this table to analyze and process messages, filter out attack packets, and provide security services for DHCPv6. For more information, see the documentation Configuring DHCPv6 Snooping (IPv6).

Support PFC Watchdog

The PFC (Priority-based Flow Control) mechanism allows downstream devices to send PFC pause frames requesting upstream devices to pause traffic transmission. During network anomalies, this mechanism may propagate PFC pause frames throughout the entire network, potentially leading to a PFC deadlock where traffic forwarding halts. The PFC Watchdog is designed to detect and automatically recover from PFC deadlocks, ensuring network stability and traffic flow. For more information, see the documentation Lossless Network Configuration.

ECMP Hash Enhancement

The ECMP (Equal-Cost Multi-Path) hash enhancement supports the following load balancing modes: Randomized Load Balance, Round-Robin Load Balance and Dynamic Load Balance Normal Mode. For more information, see the documentation Lossless Network Configuration.

[AS5835 Speed]

The AS5835-54T port operates at 10G speed even when connected to a 2.5G speed device. The bug is fixed in 4.4.5.

[S5810-28TS]

DDM Information is Incorrect.

[10G/25G/100G/400G Module]

The switch cannot recognize FS 10G/25G/100G/400G modules. The bug is fixed in 4.4.5.

[AS4630 POE]

On the AS4630, the first and last POE ports cannot power on, and abnormal power values are displayed intermittently. The bug is fixed in 4.4.5.

[S5860-48XMG/S5860-24XMG]

Fan speed reads 0 due to CPLD hardware upgrade on S5860-48XMG and S5860-24XMG models. The bug is fixed in 4.4.5.

[N8560-32C]

Breakout port experiences packet loss. The bug is fixed in 4.4.5.
