DES-3326 Layer 3 Fast Ethernet Switch User’s Guide
The Status field can be toggled between Enabled and Disabled to enable or disable the receipt of SNMP
traps by the listed management stations.
Configure Ports
Click the Configure Ports link on the Configuration menu:
Figure 7-13. Configure Port window
Click on the port you want to configure on the DES-3326 Switch front panel display at the top of the
Web page.
Use the State pull-down menu to either enable or disable a given port.
Use the Speed/Duplex pull-down menu to either select the speed and duplex/half-duplex state of the
port. Auto – auto-negotiation between 10 and 100 Mbps devices, full- or half-duplex. The Auto setting
allows the port to automatically determine the fastest settings the device the port is connected to can
handle, and then to use those settings. The other options are 100M/Full, 100M/Half, 10M/Full, and
10M/Half. There is no automatic adjustment of port settings with any option other than Auto.
Port Locking
A given port’s (or a range of port’s) dynamic MAC address learning can be locked such that the current
source MAC addresses entered into the MAC address forwarding table can not be changed once the
port lock is enabled. The port can be locked by toggling the Lock pull-down menu to Enabled, and
clicking Apply.
This is a security feature that prevents unauthorized computers (with source MAC addresses unknown
to the switch prior to locking the port (or ports)) from connecting to the switch’s locked ports and
gaining access to the network.
