Parameter
integer: Specify the VLAN delivery mode to be integer.
string: Specify the VLAN delivery mode to be string.
Description
Use the vlan-assignment-mode command to specify the VLAN delivery mode
(integer or string).
By default, the integer mode is used, that is, the switch supports the RADIUS
server delivering VLAN IDs in integer form.
Dynamic VLAN delivering aims to control the network resources available to a user.
With this function enabled, a switch adds the ports connecting to authenticated
users to specified VLANs according to the attribute values delivered by the RADIUS
server. In actual use, ports are usually set to operate in port-based mode in order
to work together with Guest VLAN. A port operating in MAC address-based mode
can only have one host connected to it. Currently, the VLAN IDs delivered by
RADIUS servers can be of integer or string type.
As for a VLAN ID that is of integer type, a switch adds the port to the
■
corresponding VLAN according to the VLAN ID delivered by the RADIUS
authentication server. If the VLAN does not exist, the switch creates the VLAN
first and then adds the port to the VLAN.
As for a VLAN ID that is of string type, a switch compares the VLAN ID delivered
■
by the RADIUS authentication server with the names of the VLANs existing on
the switch. If a matching entry is found, the switch adds the port into the
corresponding VLAN. Otherwise, the delivery fails and the user fails to pass the
authentication.
n
When configuring a VLAN delivering mode, keep the mode configured on the
■
switch consistent with the mode configured on the Radius Server.
For the string delivery mode, the value range of the VLAN name supported by
■
the switch is 1-32 characters. If the name configured on the Radius Server
exceeds 32 characters, the delivery will fail.
For the string delivery mode, a string that contains numerals only is first
■
interpreted as a number. That is, if the VLAN name delivered by the RADIUS
server contains only numerals (such as "1024"), and the equivalent integer is
within the range 1 to 4,094, the switch takes the VLAN name as an integer and
add the authenticated port to the VLAN identified by the integer (In this case,
the switch will add the port to VLAN 1024). If the equivalent integer is not
within the range 1 to 4,094 (such as string "12345"), the RADIUS server fails
to deliver the VALN name; if the all-numeral string contains space, such as " 12
345", the first block of non-spaced numbers in the string will be converted into
its equivalent integer, namely, integer 12 in this example.
Hybrid ports and Trunk ports do not support VLAN delivering; only Access ports
■
support VLAN delivering.
