MRU
mru
Overview
Use this command to set the Maximum Receive Unit (MRU) size for switch ports,
where MRU is the maximum frame size (excluding headers) that switch ports can
receive. For more information, see the
Switching Feature Overview and
Use the
no
variant of this command to remove a previously specified Maximum
Receive Unit (MRU) size for switch ports, and restore the default MRU size (1500
bytes) for switch ports.
NOTE
:
The figure of 1500 bytes specifies the payload only. For an IEEE 802.1q frame,
provision is made (internally) for the following additional components:
•
Source and Destination addresses
•
EtherType field
•
Priority and VLAN tag fields
•
FCS
These additional components increase the frame size internally to 1522 bytes.
