DGS-3312SR Gigabit Layer 3 Switch
Parameter Description
Unit This is the Unit ID of a Switch in a Switch stack. The number 15 indicates a DGS-
3312SR Switch in standalone mode.
From/To A consecutive group of ports may be configured starting with the selected port.
Mode Active – Active LACP ports are capable of processing and sending LACP control
frames. This allows LACP compliant devices to negotiate the aggregated link so the
group may be changed dynamically as needs require. In order to utilize the ability to
change an aggregated port group, that is, to add or subtract ports from the group, at
least one of the participating devices must designate LACP ports as active. Both
devices must support LACP.
Passive – LACP ports that are designated as passive cannot initially send LACP
control frames. In order to allow the linked port group to negotiate adjustments and
make changes dynamically, at one end of the connection must have “active” LACP
ports (see above).
After setting the previous parameters, click Apply to allow your changes to be implemented. The LACP Port Table shows
which ports are active and/or passive.
Port Access Entity
The Switch is an implementation of the server side of IEEE 802.1X-Port Based Network Access Control. Through this
mechanism, users have to be authorized before being able to access the network. See the following figure:
Figure 4- 11. Typical 802.1X Configuration Prior to User Authentication
Once the user is authenticated, the Switch unblocks the port that is connected to the user as shown in the next figure.
