 #### CHASSIS_APP_DB Changes
 
 The following new VOQ counters should be available for each VOQ entry in the DB:
-   * COUNTERS|fsi_id|asic_id|intf:VOQ_index
-      * SAI_VOQ_STAT_PACKETS
-      * SAI_VOQ_STAT_BYTES
-      * SAI_VOQ_STAT_DROPPED_PACKETS
-      * SAI_VOQ_STAT_DROPPED_BYTES
+   * `COUNTERS|fsi_id|asic_id|intf@fsi_id|asic_id:VOQ_index`
+      * `SAI_VOQ_STAT_PACKETS`
+      * `SAI_VOQ_STAT_BYTES`
+      * `SAI_VOQ_STAT_DROPPED_PACKETS`
+      * `SAI_VOQ_STAT_DROPPED_BYTES`
+   * The first part of the key ( before @ ) `fsi_id|asic_id|intf` denotes the physical location of the interface.
+   * The second part of the key ( after @ ) `fsi_id|asic_id:VOQ_index` denotes the location of the VOQ and its index.
 
 #### SWSS Changes
 ##### PortsOrch Changes
 PortsOrch will periodically poll the VOQ stats through SAI call `get_queue_stats` and update them into `CHASSIS_APP_DB`
 
 #### Repositories that need to be changed
-   * sonic-swss
-   * sonic-swss-common
-   * sonic-utilities
+   * sonic-swss-common: https://github.com/sonic-net/sonic-swss-common/pull/855

+   * sonic-utilities: https://github.com/sonic-net/sonic-utilities/pull/3163
    * sonic-mgmt
 
 ### SAI API 
 No new SAI API is being added. PortsOrch will use the existing SAI API i.e. `get_queue_stats`.
 
 ### Configuration and management 
 #### CLI
-CLI (VOQstat.py) aggregates the VOQ stats for a VOQ across ASICS and present a consolidated view. No new CLI command is being introduced for this rather the following CLI command is leveraged to provide this output on an SSI.
