Default settings after start-
up
Once the switch has started successfully, installation is complete and
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
certain 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.
