J Check the MPOA devices. Beginning with the router the ATM host is
having trouble communicating with, check all of the devices within the
MPOA network to ensure that they are operating correctly. Do this from
the “problem” router to the destination system. If all of the MPOA
devices are operating correctly, contact HP.
K Check the MTU sizes. To establish a one-way outbound shortcut, the
MTU size of the local ELAN interface must be less than or equal to the
MTU size of the destination ELAN interface. To establish a two-way
(bidirectional) shortcut, the MTU size of the local ELAN interface must
be the same as the MTU size of the destination ELAN interface.
Check the MTU size of the local ELAN interface and the destination
ELAN interface. If the two MTU sizes are the correct size (based on
whether the shortcut is one-way or two-way), contact HP.
