Section III: VLANs 461
Specifying a Management VLAN
The management VLAN is the VLAN on which an AT-9400 Series switch
expects to receive management packets. This VLAN is important if you
will be managing a switch remotely or using the enhanced stacking
feature of the switch.
Management packets are packets generated by a management station
when you manage a switch using the Telnet application protocol or a
web browser. The switch acts upon the management packets only if
they are received on the management VLAN.
The default management VLAN on an AT-9400 Series switch is the
Default_VLAN. If you do not create any additional VLANs and link the
switches together using untagged ports, then there is no need to specify
a new management VLAN in order to remotely manage the devices.
However, if you create additional VLANs on your switches, it may be
necessary for you to create a management communications path and
then specify that path as the new management VLAN.
Below are several rules to observe when using this feature:
❑ The management VLAN must exist on each AT-9400 Series switch
that you want to manage.
❑ Using the following procedure, you must specify the
management VLAN in the AT-S63 management software on each
slave and master switch of an enhanced stack.
❑ The uplink and downlink ports on each switch that are
functioning as the tagged or untagged data links between the
switches must be either tagged or untagged members of the
management VLAN.
❑ The port on the switch to which the management station is
connected must be a member of the management VLAN. (This
rule does not apply when managing the switch locally through
the RJ-45 terminal port.)
As an example, assume that you have an enhanced stack of seven
AT-9400 Series switches with one master switch. If the uplink and
downlink ports between the various switches are members of the
Default_VLAN and if the management station is connected to a port of
the Default_VLAN, you can manage all the switches because the
Default_VLAN is the default management VLAN.
Now assume that you decide to create a VLAN called NMS with a VID of
24 for the sole purpose of remote network management. For this, you
