Messages Related to Port-Isolation Operation
Troubleshooting Port-Isolation Operation
Message Meaning
Port Isolation
is disabled. It
must be enabled
first.
In the switch’s factory-default state or after you execute no port-isolation, you must enable
port isolation (by executing port-isolation alone) before entering commands for changing the
mode on one or more ports.
Symptom Possible Cause
Connectivity problems. • A port may be configured as a tagged member of a VLAN, or multiple VLANs may be
configured on the switch. Ensure that all ports are untagged members of VLAN 1 (the default
VLAN) and that no other VLANs are configured on the switch.
• Illegal port trunking. Port Isolation does not allow trunks on Private ports, or more than one
Port-Isolation type in a trunk. Also, Port Isolation allows an LACP trunk only on Uplink ports.
• A port on a device connected to the switch may be configured as a tagged member of a VLAN.
• GVRP may be enabled on the switch.
