Default level
2: System level
Parameters
None
Description
Use port isolate-user-vlan host to configure a port to operate in host mode.
Use undo port isolate-user-vlan to restore the default.
By default, a port does not operate in promiscuous mode or host mode.
If the port has been assigned to a secondary VLAN, the switch automatically assigns the target port to
the isolate-user-VLAN associated with the secondary VLAN. If the port has not been assigned to a
secondary VLAN, the switch immediately assigns the target port to the isolate-user-VLAN associated with
the secondary VLAN after the port is assigned to a secondary VLAN.
In automatic assignment to the isolate-user-VLAN associated with the secondary VLAN for an access port,
the switch also changes the link type of the port to hybrid, and sets the secondary VLAN as the PVID of
the port.
The link type and PVID never change on a trunk port or hybrid port in the automatic VLAN assignment
process.
After the port link type changes, the switch keeps the member attribute of the hybrid port unchanged
when it is already a tagged member of the isolate-user-VLAN, and otherwise automatically assigns the
port to the isolate-user-VLAN as an untagged member.
When you execute the undo port isolate-user-vlan command, the command cancels the host mode of a
port. It does not remove the port from the isolate-user-VLAN.
Examples
# Configure access port GigabitEthernet 1/0/1 to operate in host mode and assign the port to
secondary VLAN 20, which is associated with isolate-user-VLAN 2.
