Switch Management and Operating Concepts
•
Switch diagnostics—The PROM loader automatically runs memory diagnostics each time the
switch is booted.
•
Reset to factory defaults—The switch includes an option that allows you to reset the
configuration to the factory defaults. You can select to reset the IP address or save your
configured IP address.
Switch IP and MAC Addresses
Each switch must be assigned its own IP Address. The switch's default IP address is 10.90.90.90.
You can change the default switch IP address to meet the specification of your networking address
scheme.
The switch is also assigned a unique MAC address by the factory. You cannot change this MAC
address.
In addition, you can also set an IP address for a gateway router. This becomes necessary when the
network management station is located on a different IP network from the switch, making it
necessary for management packets to go through a router to reach the network manager, and vice
versa.
For security, you can list the IP addresses of the network management stations that you want to
manage the switch. If you list IP addresses, only those workstations have access; all others will be
denied.
You can also configure a VLAN for the network that the management stations are on, and then
configure the switch for this VLAN.
Port Configurations
By default, the switch is configured to use auto-negotiation to determine each port's speed and
duplex setting. The user can modify this and configure a port to use a specified configuration. The
Ethernet ports have the following characteristics:
Flow Control
All ports have a traffic limit because they have a limited buffer space to receive incoming frames.
Upon reaching the limit, a port either starts dropping packets or triggers flow control. The ZT8101
switch uses the following methods for flow control:
•
802.3x flow control—The switch sends PAUSE frames, which request remote ports to delay
sending packets for a period of time. Sending ports suspend further frame transmission until
the specified time period has elapsed.
•
802.3x compliant flow control—The switch does not send PAUSE frames, but it does
respond to them.
