Syntax 
mtu mtu-value 
View 
POS port view 
Parameter 
mtu: MTU on the POS port.  
mtu-value: MTU value, in the range of 64 to 9,192 (in bytes). By default, it is 1,500 
bytes. 
Note that the MTU range of 155M POS port and 10G POS port is different. The MTU of 
155M POS port ranges from 64 to 1,995 bytes. 
Description 
Use the mtu command to define the MTU on the POS port.  
Note that you must disable port by using the shutdown command first and then use the 
undo shutdown command to enable it again if the MTU values are different between 
both ends. In this case, as the result of negotiation between both ports, the smaller 
value will be used as the MTU.  
Example 
# Set the MTU on the POS port to 5000 bytes.  
<Quidway> system-view
