Maximum Unit Settings
Description
The maximum unit settings are configured using two menu items:
z
Maximum receive unit
(MRU)—Defines the maximum number of bytes that can be
received in a single packet.
z
Maximum transmit unit
(MTU)—Defines the maximum number of bytes that can be
transmitted in a single packet.
Note: During LCP negotiations on a PPP link, AI232 will advertise the MRU
configured by the user. If the peer negotiates its MRU with AI232, then the
MTU on the AI232 side will be set to the peer’s MRU. If the peer does not
negotiate its MRU, then the MTU on the AI232 side will be set to the value
configured by the user.
