Default settings after start-	Once the switch has started successfully, installation is complete and
up	the switch is using its default setting (also known as default configu-
	ration):
	•	All ports are enabled.
	•	All ports operate in auto-negotiation mode.
	•	Spanning Tree is disabled on all ports.
	•	Addresses that have been silent for more than 15 minutes are
		purged from the switch’s address table (the MAC Address Aging
		time).
	•	No access restrictions to Local Management (Telnet).
	•	No SNMP restrictions.
	•	No permanent MAC address entries defined. A permanent entry
		is a MAC address that is defined as being permitted only on a cer-
		tain port. This can be a useful security feature.
	•	All ports are in the same VLAN (named <System>) and VLAN
		mode (Stand-alone mode). VLANs allow you to create virtual
		networks using specific switch ports, IP addresses, IP subnets and
		MAC addresses.
	•	Flow Control is enabled on all ports.
	•	The connection with Local Management is timed-out after 10
		minutes if there has been no input during this period.
After start-up	This default configuration is adequate for simple workgroup environ-
	ments to operate in basic switching mode.

Although the switch continues to operate without problems, we rec- ommend that you change certain parameters to suit your own require- ments.
