Section IV: VLANs 433
Specifying a Management VLAN
The management VLAN is the VLAN through which an AT-8400 Series
switch expects to receive management packets. This VLAN is important
if you are using the enhanced stacking feature of the switch or if you are
managing a switch remotely.
Management packets are packets generated by a management
workstation while managing a switch. The management card in the
switch acts upon the packets only if they are received on the
management VLAN.
The default management VLAN on an AT-8400 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. You should be able to manage the AT-8400
Series switches in your network using the enhanced stacking feature.
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-8400 Series switch
that you want to manage.
❑ Using the following procedure, you must specify the
management VLAN in the AT-S60 software on each slave and
master switch of an enhanced stack.
❑ The uplink and downlink ports on the switch that are the data
links between the switches must be untagged members of the
management VLAN.
❑ The port on the switch to which the management station is
connected must be an untagged member of the management
VLAN. (This does not apply if the management station is
connected to the RS-232 port on the management card.)
Here is an example. Let’s assume that you have an enhanced stack of
three AT-8400 Series switches with one master switch. If the uplink and
downlink ports between the various switches are untagged members of
the Default_VLAN and if the management station is connected to a
untagged port of the Default_VLAN, you can manage all the switches
since the Default_VLAN is by default the management VLAN.
