+**show muxcable health <port>**
+
+This command displays the hardware health of  the Y-cable which are connected to muxcable. The resultant table or json output will show the current hadrware health of the cable as Ok, Not Ok, Unknown.
+
+- Usage:
+  ```
+  show muxcable health [OPTIONS] [PORT]
+  ```
+
+While displaying the muxcable health, users need to provide the following fields
+
+- PORT     required - Port name should be a valid port
+- --json   optional - -- option to display the result in json format. By default output will be in tabular format.
+
+-Ok means the cable is healthy
+
+in order to detemine whether the health of the cable is Ok
+the following are checked
+- the vendor name is correct able to be read
+- the FW is correctly loaded for SerDes by reading the appropriate register val
+- the Counters for UART are displaying healthy status 
+       i.e Error Counters , retry Counters for UART or internal xfer protocols are below a threshold
+
+
+- Example:
+    ```
+      admin@sonic:~$ show muxcable health Ethernet4
+      PORT       ATTR    HEALTH
+      ---------  ------  --------
+      Ethernet4  health  Ok
+    ```
+    ```
+      admin@sonic:~$ show muxcable health Ethernet4 --json
+    ```
+    ```json
+           {
+               "health": "Ok"
+           }
+
+    ```
+
+
+**show muxcable queueinfo <port>**
+
+This command displays the queue info of  the Y-cable which are connected to muxcable. The resultant table or json output will show the queue info in terms transactions for the UART stats in particular currently relevant to the MCU of the cable.
+
+- Usage:
+  ```
+  show muxcable queueinfo [OPTIONS] [PORT]
+  ```
+
+While displaying the muxcable queueinfo, users need to provide the following fields
+
+- PORT     required - Port name should be a valid port
+- --json   optional - -- option to display the result in json format. By default output will be in tabular format.
+
+the result will be displayed like this, each item in the dictionary shows the health of the attribute in the queue
+```
+"{'VSC': {'r_ptr': 0, 'w_ptr': 0, 'total_count': 0, 'free_count': 0, 'buff_addr': 0, 'node_size': 0}, 'UART1': {'r_ptr': 0, 'w_ptr': 0, 'total_count': 0, 'free_count': 0, 'buff_addr': 209870, 'node_size': 1682183}, 'UART2': {'r_ptr': 13262, 'w_ptr': 3, 'total_count': 0, 'free_count': 0, 'buff_addr': 12, 'node_size': 0}
+```
+
+- Example:
+    ```
+      admin@sonic:~$ show muxcable queueinfo Ethernet0
+      PORT       ATTR          VALUE
+      ---------  ----------  -------
+      Ethernet0  uart_stat1        2
+      Ethernet0  uart_stat2        1
+    ```
+    ```
+      admin@sonic:~$ show muxcable queueinfo Ethernet4 --json
+    ```
+    ```json
+           {
+               "uart_stat1": "2",
+               "uart_stat2": "1",
+
+           }
+    ```
+
+**show muxcable operationtime <port>**
+
+This command displays the operationtime of  the Y-cable which are connected to muxcable. The resultant table or json output will show the current operation time of the cable as `hh:mm:ss` format. Operation time means the time since the last time the reseated/reset of the cable is done, and the time would be in the format specified
+
+- Usage:
+  ```
+  show muxcable operationtime [OPTIONS] [PORT]
+  ```
+
+While displaying the muxcable operationtime, users need to provide the following fields
+
+- PORT     required - Port name should be a valid port
+- --json   optional - -- option to display the result in json format. By default output will be in tabular format.
+
+
+- Example:
+    ```
+      admin@sonic:~$ show muxcable operationtime Ethernet4
+      PORT       ATTR            OPERATION_TIME
+      ---------  --------------  ----------------
+      Ethernet4  operation_time  00:22:22
+    ```
+    ```
+      admin@sonic:~$ show muxcable operationtime Ethernet4 --json
+    ```
+    ```json
+           {
+               "operation_time": "00:22:22"
+           }
+    ```
+
+**show muxcable resetcause <port>**
+
+This command displays the resetcause of  the Y-cable which are connected to muxcable. The resultant table or json output will show the most recent reset cause of the cable as string format.
+
+- Usage:
+  ```
+  show muxcable resetcause [OPTIONS] [PORT]
+  ```
+
+While displaying the muxcable resetcause, users need to provide the following fields
+
+- PORT     required - Port name should be a valid port
+- --json   optional - -- option to display the result in json format. By default output will be in tabular format.
+
+the reset cause only records NIC MCU reset status. The NIC MCU will automatically broadcast the reset cause status to each TORs, corresponding values returned
+display cold reset if the last reset is cold reset (ex. HW/SW reset, power reset the cable, or reboot the NIC server)
+display warm reset if the last reset is warm reset (ex. sudo config mux firmware activate....)
+the value is persistent, no clear on read
+
+- Example:
+    ```
+      admin@sonic:~$ show muxcable resetcause Ethernet4
+      PORT       ATTR           RESETCAUSE
+      ---------  -----------  ------------
+      Ethernet4  reset_cause    warm reset
+    ```
+    ```
+      admin@sonic:~$ show muxcable resetcause Ethernet4 --json
+    ```
+    ```json
+           {
+               "reset_cause": "warm reset"
+           }
+    ```
