protocols such as SNMP, TFTP, ICMP (ping), DHCP and Telnet. All
servers/stations using these protocols must tag the management frames sent to
the unit with the value of the VLAN ID-Management parameter.
Valid values: 1 to 4094 or 65535 (No VLAN).
The default value is 65535.
If the VLAN ID-Management is other than 65535:
Only single-tagged management frames with a matching VLAN ID, or double-
tagged management frames with a matching Service Provider VLAN ID
received on either the Ethernet or wireless link ports are forwarded to the
unit.
A VLAN Management Tag is inserted in all management frames generated by
the unit before transmission on either the Ethernet or wireless link port. The
tag includes the values of the VLAN ID-Management and the VLAN Priority-
Management parameters.
If the VLAN ID-Management is 65535 (No VLAN):
For Access, Trunk and Hybrid links: Only untagged management frames
received on either the Ethernet or wireless link ports are forwarded to the
unit.
An AU operating in Service Provider link mode with VLAN ID – Management =
65535 cannot be managed from either the Ethernet or wireless ports.
An SU operating in Service Provider link mode with VLAN ID – Management =
65535 will accept untagged management frames from the Ethernet port. From
the wireless port it will accept only tagged frames with a VLAN ID tag that
matches the defined Service Provider VLAN ID.
Management frames generated by the unit are not tagged.
The following table summarizes the functionality of the internal management port
in accordance with the value of the VLAN ID-Management parameter. The table is
valid for all link types. Refer to the VLAN Link Type - Access Link, Trunk Link
and Service Provider Link options for some restrictions when configuring this
parameter.
