Troubleshooting Checklist

4-8 Troubleshooting

Cannot contact the
switch through in-
band management.

IP address not assigned.

Refer to the

SecureStack B2 Configuration Guide

for the IP

address assignment procedure.

Port is disabled.

This is normal if the switch is a Member in a stack.
If operating as a standalone switch or as the Manager in a
stack, enable the port. Refer to the

SecureStack B2

Configuration Guide

for instructions to enable/disable ports.

No link to device.

Verify that all network connections between the network
management station and the device are valid and operating.
If the problem continues, contact Enterasys Networks for
technical support.

Port(s) goes into
standby for no
apparent reason.

Loop condition detected.

Verify that Spanning Tree is enabled. Refer to the

SecureStack B2 Configuration Guide

for the instructions to

set the type of STA.
Review the network design and delete unnecessary loops.
If the problem continues, contact Enterasys Networks for
technical support.

User parameters
(IP address, device
and module name,
etc.) were lost
when the switch
power was cycled.

Clear NVRAM was set using
CLI commands.

Reenter the lost parameters as necessary. Refer to the

SecureStack B2 Configuration Guide

for the instructions to

configure the switch using CLI commands.
If the problem continues, contact Enterasys Networks for
technical support.
