3. Verify that the event area for the port state entry is
pstate
.
The command entry
AC
indicates that the port has completed point-to-point initialization. For example:
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 fabric device, the port becomes an F_Port. If the opposite
device is another switch, the port becomes an E_Port.
Some fabric devices have problems with loop initialization. If this is evident, issue the
portCfgPort port_#, 1
command.
Correcting a port that came up in the wrong mode
1. Issue the
switchShow
command.
2. Note the comment fields (see Table 28 ) and follow the suggested actions.
Correcting 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, the switch SFP, the cable, the edge device, and the edge device SFP).

Table 28 Switchshow output and suggested action
Output Suggested action
Disabled Check the output from the
switchShow
command to determine whether the switch is
disabled. If the switch is disabled (for example, due to persistent disable or security
reasons), attempt to resolve the issue, and then issue the
portEnable
command.
Bypassed Check the output from the
switchShow
command to determine whether the port is
testing.
Loopback Check the output from the
switchShow
command to determine whether the port is
testing.
E_Port If the opposite side is not another switch, the link came up in a wrong mode. Check the
output from the
portLogShow
or
PortLogDump
command and identify the link
initialization stage to determine where the initialization procedure went wrong.
F_Port If the opposite side of the link is a fabric device, the link came up in a wrong mode.
Check the output from
portLogShow
or
PortLogDump
command.
G_Port The port did not come up as an E_Port or F_Port. Check the output from
portLogShow
or
PortLogDump
command 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 came up in a wrong mode. Check the
output from
portLogShow
or
PortLogDump
command and identify the link
initialization stage where the initialization procedure went wrong.
