The following types of ports can be defined:
• Protected Port — Can send traffic only to uplink ports.
•
Community Port — A protected port that is associated with a community.
It can send traffic to other protected ports in the same community and to
uplink ports.
•
Uplink Port — An uplink port is an unprotected port that can send traffic
to any port.
•
Isolated Port — A protected port that does not belong to a community .
Port Protection is independent of all other features and configuration
settings. Two protected ports in a common VLAN cannot communicate with
each other.
Protected Port Restrictions
The following restrictions apply to protected ports:
• When a protected port is placed in a LAG, it loses its protected port
attribute and takes upon itself the LAG's protection attributes. When the
port is removed from the LAG, its attributes are re-applied.
• Mirrored traffic is not subject to protected ports rules.
• Routing is not affected by the protected port forwarding rule, so that if
a
pack
et enters a protected port, it can be routed by the device
to another
protected
port.
