Why I did it
On DNX (J2/J2c/J2c+) platforms, Single Path Nexthops and ECMp Nexthop resources(FECs) are shared. BRCM SAI do not have partition of this resource, and hence more single path Nexthop entries, causes ECMP programming to fail in scaled setup.
How I did it
Broadcom provided SAI changes to reserve resources for single path nexthop entries(More details in CSP: https://brcmsemiconductor-csm.wolkenservicedesk.com/wolken-support/allcases/request-details?requestId=CS00012251649).
Along with SAI changes, they provided configurable Macro/flag to reserve NON_ECMP entries.
This PR is to add that flag in various sai.profile files wherever applicable.
PS: We are reserving 3072 single path Nexthop entries on each Linecard. Calculation is as follows.
Max Slots per chassis: 8
Max No of Ports(each LC): 64
MyIP/Subnet Entries per port: 4(v4/v6)
Nbr Entries Per port: 2(v4/v6)
Total Non_ECMP Count: 8x64x(4+2) = 3072
How to verify it
Without this change, the ECMP group count will be shown as Max_count in 'crm show resources all' command, and with this change the ECMP group count will be decreased by 24(3072/128).
For 7800 LCs, set LAG mode to support 1024 number of 16-member system
LAGs.
Why I did it
The SOC property changes are necessary to match #10519 which increases the number of system LAG IDs to 1024.
Description for the changelog
For 7800 LCs, set LAG mode to support 1024 number of 16-member system
LAGs.
Update the bcm config file system_ref_core_clock_khz param to handlesystems with J2cplus linecards.
We need system_ref_core_clock_khz to be set to 1600000 for supporting j2 and j2cplus linecards on the same chassis.
Why I did it
The buffer pool & profile setting in buffer template was not correct and caused the errors like the following:
ERR swss#orchagent: :- parseReference: malformed reference:[BUFFER_PROFILE|ingress_lossless_profile]. Must not be surrounded by [ ]
How I did it
Fix the buffer pool & profile setting by removing "[]".
How to verify it
Loaded image with this fix in a switch and made sure the error was not seen anymore.
This change introduces 3 columns in the port_config.ini file.
These are coreId, corePortId and numVoq.
The ports for inband and recirc were also renamed properly.
