Flowchart 5 Procedures
The procedures in Flowchart 5 are:
• Enter ping(1M) to the remote host. If ping is successful, continue to the Transport
Level Test (Flowchart 6).
•Ifping is not successful, enter netstat -in to verify MTU size. Ensure that the
MTU size is the same on both the local and remote hosts (9000 for Jumbo Frames
and 1500 for standard frames) by entering lanadmin -M
new_mtu ppa
, and repeat
the ping Test. Jumbo Frames are supported in Gigabit Ethernet only, not in Fast
Ethernet.
• If ping is still not successful and you are either (1) not using Jumbo Frames or (2)
using Jumbo Frames with the correct speed setting, continue to the next flowchart
(Figure 6-6) to validate the network, remote host and configuration settings.
• If the link speed is not appropriate (1000 Mbit/s for Gigabit and 10/100 Mbit/s for
Fast Ethernet), set it with lanadmin -X
speed ppa
, and repeat the ping Test.
