Configures global MiNT MTU (Multiple Transmission Unit). Use this command to specify the maximum packet size, in bytes, for MiNT. routing. Higher the MTU values, greater is the network efficiency. The user data per packet increases, while protocol overheads, such as headers or underlying per-packet delays remain the same.

Supported in the following platforms:

  • Access Points — AP505i, AP510i/e, AP560i/h
  • Service Platforms — NX5500, NX7500, NX9500, NX9600, VX9000


mtu <900-1500>


mtu <900-1500>

mtu <900-1500>

Specifies the maximum packet size from 900 - 1500 bytes

The maximum packet size specified is rounded down to a value using the following formula: 4 + a multiple of 8.

The MTU setting specifies the maximum packet size used for MiNT packets. Larger packets are fragmented to fit within the specified packet size limit. You may want to configure this parameter if the MiNT backhaul network requires or recommends smaller packet sizes. The default value is 1500 bytes.
