Chapter 8 Troubleshooting Ports
Common Problems with Port Interfaces
Port Remains in Initializing State
Symptom
Port remains in the initializing state.
A port goes into the initialization state after a successful completion of link level initialization. For Fx
and FL types of ports, the next step is to complete the FLOGI process. The port remains in the
initialization state until the FLOGI (fabric login) process completes.
For E or TE port types, the next step is to complete the ELP process. If the ELP fails the port is moved
to the offline state after a timeout and the entire process repeats until the port comes online.
Table 8-4
lists possible causes for FLOGI to fail for a given port and possible solutions.
Note
We recommend that you do not disable and then enable a T or TE port. This would affect all the VSANs
crossing the EISL instead of just the VSAN experiencing the problem.

Port Remains in the Initializing State
Symptom
Possible Cause
Solution
Port remains in the
initializing state.
The port is up because the link partner
has put itself in a bypass mode.
Use the
show hardware internal fc-mac port
port
statistics
command to check whether the Class-3 input
counter is increasing after the successful completion of link
initialization.
Note
You must use the
attach module
CLI command to
access the FC-MAC show commands.
The FLOGI packet was dropped
somewhere in the data path, starting
from FC-MAC to the FLOGI server.
Use the
show hardware internal fc-mac port
port
statistics
command to check for Class-3 packet counters.
Note
You must use the
attach module
CLI command to
access the FC-MAC show commands
Analyze the output of the
show hardware internal error
command for a possible drop of FLOGI packets somewhere
in the path. See the
“NoteWe recommend that you do not
disable and then enable a T or TE port. This would affect
all the VSANs crossing the EISL instead of just the VSAN
experiencing the problem.” section on page 8-16
.
Right-click on the port in Device Manager and select
disable
and then
enable
, or use the
shut CLI
command
followed by the
no shut
command to disable and enable the
port. If this does not clear the problem, try moving the
connection to a different port on the same or another
module.
A software bug resulted in an error
while handling the FLOGI packet.
