I currently have an SRX router capable of transmitting 9K packets when using PPPoE. I am given to understand that the Huawei cards in the nearby FTTC cabinet are also capable of handling 9K packets.

Presently, I am using baby jumbo frames which noticeably improve response times. I should like to investigate using larger packet sizes, provided the 130 handles them correctly. Is there a practical limit to the packet size that the 130 will pass?
