Added support data for fabric monitoring in CONFIG_DB
The CONFIG_DB now has the FABRIC_MONITOR|FABRIC_MONITOR_DATA table for default value for fabric port monitoring. An example output of getting this table is:
sonic-db-cli CONFIG_DB hgetall "FABRIC_MONITOR|FABRIC_MONITOR_DATA"
{'monErrThreshCrcCells': '1', 'monErrThreshRxCells': '61035156', 'monPollThreshIsolation': '1', 'monPollThreshRecovery': '8'}
The CONFIG_DB now also has a table for each fabric port for its isolate status.
An example output of getting this table is:
sonic-db-cli CONFIG_DB hgetall "FABRIC_PORT|Fabric20"
{'alias': 'Fabric20', 'isolateStatus': 'False', 'lanes': '20'}
* Update PG headroom settings ports based on port speed/cable length
* Updated XOFF settings to use chip level numbers than core
* Updated PG headroom based on uplink/downlink side
* fix for sonic-config-gen tests
* More fixes for unit test cases
* more test fixes
* Merged multiple functions into one
Why I did it
Update ECN settings for T2 chassis
How I did it
Updated qos config file to load these settings during switch bootup
How to verify it
Verified on line card on T2 chassis
Why I did it
Support Egress Mirroring on supported Arista platforms
How I did it
Add necessary soc properties for egress mirroring recycle ports to be created
Signed-off-by: Nathan Wolfe <nwolfe@arista.com>
Updated asic_port_names for all Arista LC SKUs to follow latest naming
conventions to remove redundant ASICx suffix. For
Arista-7800R3-48CQ2-C48, added the asic_port_name mapping.
Provide platform-components.json for Clearwater2 and Wolverine
These files are needed for fwutil platform sonic-mgmt tests to pass.
Fix PikeZ platform_components.json

To support 64 cores on arista skus. Fixesaristanetworks/sonic#77
Remapped recycle ports to lowers core port ids and set appl_param_nof_ports_per_modid to 64.
Why I did it
The current platform.json contains entries for thermals and SFPs that do not exist on Wolverine.
How I did it
I removed the incorrect entries.
How to verify it
Verify using applicable sonic-mgmt platform API tests.
Eariler the SDK stat polling was erroneously set to once every msec
which is far more frequent than required by SWSS. The new setting, which
is consistent with other vendor SKUs, is once a second. The net result
is reduced CPU MHz by syncd.
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).
Port indexes of front panel ports are not contiguous in multi-asic because we didn't distiguish between
front panel and internal ports, e.g., recycle ports. Fix this by assigning index to front panel port first
and then internal ports.
Add missing aggregate port_config.ini needed by sonic-mgmt
Concatenate the ASIC specific port_config.ini from device/arista/x86_64-arista_7800r3a_36d2_lc/Arista-7800R3A-36D2-C36/[01] to create the aggregate file.
Why I did it
TX FIR tuning should be done based on the type of inserted transceiver
How I did it
Add media_settings.json which contains the tuning data for 100G optic and 400G optic.
How to verify it
Tested against x86_64-arista_7800r3a_36d2_lc
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.
Why I did it
This linecard runs in multi-asic mode and therefore needs the use_pcie_id_chassis file to work properly.
The default_sku file was also missing which would break the boot when no minigraph is provided.
Description for the changelog
Add missing default_sku and use_pci_id_chassis configs for 7800R3A-36D2
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.
