Cannot contact the
switch through in-
band management. IP address not assigned. Refer to the SecureStack C2 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
C2 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 C2 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

configure the switch using CLI commands.
