setinterface_mtu

Use this method to set the Maximum Transmission Unit (MTU) is the largest packet size, measured in bytes excluding 14 bytes ethernet header and 4 bytes CRC, that can be transmitted and received by an interface. The default value of MTU is 1500 on all the interface of Citrix ADC, some Cloud Platforms will restrict Citrix ADC to use the lesser default value. Any MTU value more than 1500 is called Jumbo MTU and will make the interface as jumbo enabled. The Maximum Jumbo MTU in Citrix ADC is 9216, however, some Virtualized / Cloud Platforms will have lesser Maximum Jumbo MTU Value (9000). In the case of Cluster, the Backplane interface requires an MTU value of 78 bytes more than the Max MTU configured on any other Data-Plane Interface. When the Data plane interfaces are all at default 1500 MTU, Cluster Back Plane will be automatically set to 1578 (1500 + 78) MTU. If a Backplane interface is reset to Data Plane Interface, then the 1578 MTU will be automatically reset to the default MTU of 1500(or whatever lesser default value). If any data plane interface of a Cluster is configured with a Jumbo MTU ( > 1500), then all backplane interfaces require to be configured with a minimum MTU of 'Highest Data Plane MTU in the Cluster + 78'. That makes the maximum Jumbo MTU for any Data-Plane Interface in a Cluster System to be '9138 (9216 - 78)., where 9216 is the maximum Jumbo MTU. On certain Virtualized / Cloud Platforms, the maximum possible MTU is restricted to a lesser value, Similar calculation can be applied, Maximum Data Plane MTU in Cluster = (Maximum possible MTU - 78).

Syntax



Parameters

id

ID of the Interface whose parameters you want to modify. For a Citrix ADC, specify the interface in C/U notation (for example, 1/3). For a cluster configuration, specify the interface in N/C/U notation (for example, 2/1/3). where C can take one of the following values: * 0 - Indicates a management interface. * 1 - Indicates a 1 Gbps port. * 10 - Indicates a 10 Gbps port. U is a unique integer for representing an interface in a particular port group. N is the ID of the node to which an interface belongs in a cluster configuration. Use spaces to separate multiple entries.
This is mandatory parameter.

Default value = 1500.
Minimum value = 1500.
Maximum value = 9216.
