Stricter policer policy      

The Cisco 8122-64EH-O router enforces a stricter policer policy. To compensate, configure the Class of Service (CoPP) policy to accommodate a rate 1.7 times the anticipated punt rate (in packets per second).

MTU modification and drop counters       

The default Maximum Transmission Unit (MTU) modification functions as expected on the Cisco 8122-64EH-O router; however, drop counters do not increment.

QoS configuration on PIE ports     

If the DEVICE_NEIGHBOR table lacks port entries, QoS configuration is incorrectly applied to all ports, including PIE ports, which do not support QoS.

SONiC does not handle errors when QoS configuration fails on PIE ports.

The necessary fix is missing from the SONiC branch (see Pull Request #21036 on the sonic-net/sonic-buildimage repository: "Exclude PIE ports from buffer and qos configuration").

Workaround:

To prevent QoS and buffer configuration issues on unsupported ports, define the ports in the DEVICE_NEIGHBOR table before applying QoS and buffer configurations. For example:"
For example:

"DEVICE_NEIGHBOR": {

        "Ethernet32": {

            "name": "Ixia",

            "port": "Card1/Port1"

        },

        "Ethernet96": {

            "name": "Ixia",

            "port": "Card1/Port2"

        }

}

MAC learning

Line card VLANs with port channels might have missing MAC entries in the Forwarding Database (FDB) table.

Build-Your-Own (BYO) bundle compatibility

The Build-Your-Own (BYO) bundle for the 8122-64EH and 8122-64EHF platforms is compatible with the 202405 Azure SONiC build image up to SHA1 ec0742534c45bc012bcd0551adc8029d7d9f87ed (dated April 4, 2025) or earlier.

To ensure compatibility with newer SHA1 versions, Azure SONiC build image PR #21924 must be reverted during the SONiC image build process.
