Configuring the Jumbo Frame Length

Configuring the Jumbo Frame Length

  • In versions earlier than V100R005C10, run the jumboframe enable value command in the interface view to configure the maximum length of a jumbo frame.
  • In V100R005C10 and later versions, run the jumboframe enable value1 [ value2 ] command in the interface view to configure the maximum length of a jumbo frame value1 and the threshold of a non-jumbo frame value2. The switch forwards a frame whose length ranges from value1 to value2 (excluding value2) as a jumbo frame and discards a frame whose length is greater than value1. The switch forwards a frame whose length is less than or equal to value2 as a normal frame and does not count it as a jumbo frame.
    NOTE:
    The CE12800E that has the ED-E/EG-E/EGA-E series cards installed, CE5810EI and CE6880EI do not support the value2 parameter.
Table 15-2 lists the length range and default length of a jumbo frame.
NOTE:

In the following table, the value range of value1 complies with that in V200R005C00 and later versions. In versions earlier than V200R005C00, the minimum value of value1 is 1536 bytes.

The value ranges from 1518 to 12288.

# Set the maximum frame length allowed by 10GE1/0/1 to 5000 bytes and the threshold of a non-jumbo frame to 2000 bytes.
