Configure MTU size

The Maximum Transmission Unit (MTU) for EC-M, EC-L, and EC-XL networks defaults to 1500 bytes but can be customized per VLAN on the router. IP packets exceeding the configured MTU size may be fragmented or discarded based on the "Don't Fragment" (DF) flag bit. The Maximum Segment Size (MSS) remains fixed at 1098 bytes, independent of the MTU setting.

MTU Configuration Steps​

  1. Select Location

    • Navigate to Locations and select the location where you want to modify the MTU size for a VLAN.

  2. Configure VLAN MTU Size

    • Go to VLANs within your selected location.
    • Open the specific VLAN and adjust the LAN IP MTU by entering the desired MTU size.
    • Confirm the entered value and save all changes.

  3. Repeat Configuration

    • If applicable, repeat step 1 and 2 for any other locations requiring MTU adjustments.

  4. Submit Configuration Order

    • Once all changes are made, finalize by submitting the configuration order.
