Znyx Networks bh5700 Configuration Troubleshooting, Determining ekey status for a specific slot

Configuration Troubleshooting

Problem	Solution
No Connection	Physical Link problem. Check to see if the port LED is lit. If
	the LED port is not lit, then you may have a bad cable
	connection.
	OR
	Configuration Error. Connect through the console port (See
	Chapter 10). Use the ifconfig command to see all of the
	configured interfaces on the Ethernet Switch Blade and their
	IP addresses. Check to make sure that the IP address of the
	switch and the subnet mask are properly set. Also, the section
	on No Connection for more information.
Decreased throughput	You should make sure that your network topology contains no
	data path loops. Between any two end nodes, there should be
	only one active cabling path at any time. Data path loops will
	cause broadcast storms that will severely impact your network
	performance. See the section on Diminished Network
	Throughput.
High Error Rates, Decreased	If the interfaces on the Ethernet Switch Blade and the node
Throughput	board are not set to auto by default, the link may not negotiate
	correctly. See the section on Connecting to Devices with Fixed
	Port Speeds.
Ext FLT LED on	The EXT FLT LED indicates that communications could not
	be established with one or more remote partner devices on an
	active port or ports. Ports which were configured to be up (via
	ifconfig), but do not have remote partner devices attached,
	can cause the EXT FLT LED to be lit, even if there are no
	hardware problems with the switch. See the Network
	Configuration Problems chapter for more information
Ekey Disabled	By default, if there is no device plugged into a node slot in the
	ATCA chassis, the Shelf Manager will ekey disable the port.
	If a node board is inserted and the ports on the Ethernet Switch
	Blade are still ekey disabled by the Shelf Manager, check to
	see if the node board has been properly activated by the Shelf
	Manager.

Determining ekey status for a specific slot

You can determine the current state of any link by using the zlc command. The zlc command will output the current status of any/all Ethernet ports and their ekey status that was set by the Shelf Manager.
