- Protected Ports provide Layer 2 isolation between interfaces (Ethernet
ports and LAGs) that share the same VLAN.
- Packets received from protected ports can be forwarded only to
unprotected egress ports. Protected port filtering rules are also applied
to packets that are forwarded by software, such as snooping
applications.
- Port protection is not subject to VLAN membership. Devices connected
to protected ports are not allowed to communicate with each other, even
if they are members of the same VLAN.
- Both ports and LAGs can be defined as protected or unprotected.
Protected LAGs are described in the Configuring LAG Settings section.
• Member in LAG—If the port is a member of a LAG, the LAG number
appears; otherwise this field is left blank.
STEP 6 Click Apply. The Port Settings are written to the Running Configuration file.
