Specifying a Management VLAN
The management VLAN is the VLAN on which an AT-8524M 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
workstation when you manage a switch using the Telnet application
protocol or a web browser. The switch will act upon the management
packets only if they are received on the management VLAN.
The default management VLAN on an AT-8524M switch is the
Default_VLAN. If you do not create any additional VLANs and link the
switches together using untagged ports, then there will be 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-8524M switch that
you want to manage.
❑ Using the following procedure, you must specify the
management VLAN in the AT-S62 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 RS-232 terminal port.)
As an example, assume that you have an enhanced stack of seven
AT-8524M 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.
