Section V: VLANs 579
Specifying a Management VLAN
The management VLAN is the VLAN on which an AT-8500 Series switch
expects to receive management packets. This VLAN is important if you will
be managing a switch remotely, using the enhanced stacking feature of
the switch, or activating the BOOTP or DHCP client.
Management packets are packets generated by a management
workstation when you manage a switch using the Telnet application
protocol, SSH, or a web browser. The switch will act upon the
management packets only if they are received by a port that is a member
of the management VLAN.
The default management VLAN on an AT-8500 Series switch is the
Default_VLAN. If you do not create any additional VLANs and link the
switches together using untagged ports, then you do not 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:
ˆ The management VLAN must exist on each AT-8500 Series switch
that you want to manage.
ˆ 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.
ˆ 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.
ˆ When managing a switch or enhanced stack remotely using Telnet,
SSH or a web browser, the remote management workstation must be
communicating with the switch through the management VLAN. (This
rule does not apply when managing the switch locally through the RJ-
45 terminal port.)
ˆ If you activate the BOOTP or DHCP client on a switch, the BOOTP or
DHCP server on the network must be communicating with the switch
through a port that is a member of the management VLAN.
As an example, assume that you have an enhanced stack of seven
AT-8500 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.
