Link Training
|
Link Training is a process by which the transmitter and receiver on a high-speed serial link communicate with each other in order to tune their equalization settings.
In theory, link training enables automatic tuning of the finite impulse response (FIR) filter for each channel in ASIC to achieve the desired bit error rate (BER).
In the SONiC system, the ODM vendors rarely provide pre-calibrated pre-emphasis for QSFP(DD) CR/KR modules, which could result in the link reliability issues. With this feature, both IEEE clause 72 and 93 will be activated to dynamically tune the transmitted
signal to improve the link quality over the copper cables. This feature could be activated with or without AutoNeg.

Auto Neg Enhancement
|
Autonegotiation is a signaling mechanism and procedure used by Ethernet over twisted pair or optical media by which two connected devices choose common transmission
parameters, such as speed, duplex mode, and flow control.
In the case of SONiC, this feature supports two different types of AutoNeg
1. QSFP(DD) CR/KR modules: This feature provides autonegotiation support for speed, FEC and TX_FIR, the LinkTraining will always be activated when autonegotiation is enabled, and users could enable standalone-link-training to activate the clause 72/93 when
autonegotiation is disabled.
2. Native RJ45 ports of non-Gearbox design: This feature provides autonegotiation support for speed and duplex to the native RJ45 coppers if they're manageable by the SAI without external PHY drivers on the Gearbox. As of now, this is only applicable to the
Broadcom HX5 platforms in the SONiC. (e.g. Accton AS4630, Dell N3248TE)

SNMP Enhancement

file open failure. There is a possibility for snmpd try to open a device file (for reading statistics) which is already deleted by other applications.

Nbrmgrd Enhancements
|
On SVI interface, neighbor table entries could transition between Drop and Forward as the corresponding MAC entry ageout and re-learn. The enhancement in nbrmgrd is to send periodic
ARP request or Neighbor solicitation. ARP reply or NA message in response to the request will reset MAC ageout and ARP/ND aging in kernel to prevent premature neighbor table entry state transition.

Port-security
|
Port-security is an L2 protection feature that allows you to control the maximum number of MAC addresses the switch learns on an interface. This is an important feature for Internet Exchange Points (IXP),
commonly only one MAC address is allowed per interface or per interfance&vlan. The default behavior in case of a violation is to shut down that port. Alternatively, in case of a violation, the port could enter into a Protected mode, in that case, the packets
or frames from the additional MAC address(es) are dropped.
