Setup Guide

3. Verify the event area for the port state entry is pstate. The command entry

indicates that the port has completed point-to-

point initialization.

time task event port cmd args

-------------------------------------------------

11:38:21.726 INTR pstate 4 AC

4. Skip over the loop initialization phase.

After becoming an active port, the port becomes an F_Port or an E_Port depending on the device on the opposite side. If the

opposite device is a host or target device, the port becomes an F_Port. If the opposite device is another switch, the port

becomes an E_Port.

If there is a problem with the host or target device, enter portCfgGPort to force the port to try to come up as point-to-point only.

Correcting a port that has come up in the wrong mode

1. Enter the switchShow command.

2. Check the output from the switchShow command and follow the suggested actions in Table 4 .

TABLE 4 SwitchShow output and suggested action

Output Suggested action

Disabled If the port is disabled because persistent disable or security reasons,

attempt to resolve the issue and then enter the portEnable or, if

persistently disabled, portCfgPersistentEnable command.

Bypassed The port may be testing.

Loopback The port may be testing.

E_Port If the opposite side is not another switch, the link has come up in a

wrong mode. Check the output from the portLogShow or

PortLogDump commands and identify the link initialization stage

where the initialization procedure went wrong.

F_Port If the opposite side of the link is a private loop device or a switch, the

link has come up in a wrong mode. Check the output from

portLogShow or PortLogDump commands.

G_Port The port has not come up as an E_Port or F_Port. Check the output

from portLogShow or PortLogDump commands and identify the link

initialization stage where the initialization procedure went wrong.

L_Port If the opposite side is not a loop device, the link has come up in a

wrong mode. Check the output from portLogShow or PortLogDump

commands and identify the link initialization stage where the

initialization procedure went wrong.

NOTE

If you are unable to read a portlog dump, contact your switch support provider for assistance.

Marginal links

A marginal link involves the connection between the switch and the edge device. Isolating the exact cause of a marginal link involves

analyzing and testing many of the components that make up the link (including the switch port, switch SFP, cable, edge device, and edge

device SFP). Troubleshooting a marginal link can involve inspecting the error counters described in Troubleshooting a marginal link on

page 42 or running diagnostics on a link, a port, or an end-to-end path.
