[WiFi] Split phy-rate into rx/tx pay-rate leaves
Source: https://github.com/openconfig/public/blob/c28f23731fe0d7b5816746bccef1efa25075b36a/release/models/wifi/openconfig-wifi-mac.yang#L1292
"Last used PHY rate of connected client."
Prescribed intent: Last used PHY rate based on frames received by the AP from client.
Vendor interpretations Arista TBD: Unimplemented, asking for clarification on which value to use
Aruba “The rate used by the AP to transmit the most recent 802.11 data frame to the specific client at the last sample time.”
Problem(s) Model does not specify how the PHY rate is formed, from frames received or transmitted by the AP to/from a client. When asked to support this leaf, Arista asked for clarification but assumed received phy-rate would be the right value to use, which would have been different from Aruba’s implementation.
User Case Identify AVG phy rates in one, or both, directions used by clients. This will help with identifying link health; ie whether a client is typically utilizing low MCS rates, while other clients in the area are high, given the same SNR.
Solution Both are important for debug purposes of downlink vs uplink issues, the leaf should be split into both receive and transmit phy-rate.
