Juniper NFX250 - Managing MTU

user@jdm# delete virtual-network-functions vnf-nameinterfacesinterface-name mac-address
mac-address
NOTE:
•
To delete or modify the MAC address of a VNF interface, you must stop
the VNF, make the necessary changes, and then start the VNF.
•
The MAC address specified for a VNF interface can be either a system MAC
address or a user-defined MAC address.
•
The MAC address specified from the system MAC address pool must be
unique for VNF interfaces.
Managing MTU
The maximum transmission unit (MTU) is the largest data unit that can be forwarded
without fragmentation. You can configure either 1500 bytes or 2048 bytes as the MTU
size. The default MTU value is 1500 bytes.
NOTE: MTU configuration is supported only on VLAN interfaces.
1. To configure MTU on a VNF interface:
user@jdm# set virtual-network-functions vnf-name interfaces interface-name mtu size
NOTE: You must restart the VNF after configuring MTU if the VNF does
not support hot-plugging functionality.
2. To delete MTU of a VNF interface:
user@jdm# delete virtual-network-functions vnf-name interfaces interface-name mtu
NOTE: After the deletion of MTU, the MTU of VNF interface is reset to
1500 bytes.
NOTE:
•
MTU size can be either 1500 bytes or 2048 bytes.
•
The maximum number of VLAN interfaces on the OVS that can be
configured in the system is limited to 25.
•
The maximum size of the MTU for a VNF interface is 2048 bytes.
