Switch User Manual

C H A P T E R 1 Intel Express 520T Switch

Default settings after start-

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.
