How to check the send and receive buffer size configurd for interfac ?

[Network_Sarovani]

Hi Experts , 

We have 10Gig interface which is connected to the server , We would like to know the send and receive buffer size of this interface say Eth1/47 ? Is there any command to know the buffer value ?

We have already done Fiber link test and sfp reseating .

this step is taken form Cisco Doc. and it valid to cut-through SW "include nexus"

for example Server-1 show error <-we start from Here 
Server-1 connect to NSK-2 via Eth1
show interface 
under Eth1 if we see any output error then the SW receive corrupted frame from other interface 

show interface counters errors non-zero

any interface have FCC-Err or RCV-Err this what looking for, 
show CDP neighbor 

we know interface have FCC/RCV-Err from previous step now we looking for which neighbor connect to this interface, the neighbor is NSK-1

show interface 

check the interface in NSK-1 connect to NSK-2,
1-if the interface have output error then the NSK-1 receive corrupted frame from other NSK
2-if the interface have no output error then the cable between two NSK is damage and need to replace

counties...
the interface have output error, 
show interface counters errors non-zero

any interface have FCC-Err or RCV-Err this what looking for, this time the interface is connect to other Server/Client not connect to other NSK.
we go to that Server/client and check to see if NIC is show any error if it not show any error then cable between server and NSK-1 is damage.
