Command Usage
• Management VLANs can be defined for secure management access to
the ECN330-switch. Only IP addresses assigned to these management
VLANs can be used to manage the ECN330-switch.
The default management VLANs assigned to the switch are described
under “Enabling the SBC to Access Advanced Management Tools” on
page 74.
• The management VLAN applies to management access through the
web, Telnet, SSH, and SNMP.
• There may be one or more management VLANs on the ECN330-switch,
depending on whether the switch is set the ECN330 mode or ECN330-
switch mode (see section 7.5.12 on page 557).
• When a management VLAN is defined, IP addresses assigned to other
non-management VLAN interfaces cannot be used for management
access. When no management VLAN is defined, the ECN330-switch
can be managed through any IP address assigned to any VLAN
interface.
• Management VLANs operate as an isolated VLAN. Data traffic is not
routed to or from other VLANs, routing protocols cannot be enabled on
these interfaces, nor is the management IP interface advertised by
routing protocols to other routers.
• A management VLAN cannot be deleted when a IP address is assigned
to the interface.
• To change one of the management VLANs, first use the vlan
command (section 7.17.3 on page 850) to set up a new VLAN without
naming it, use the switchport allowed vlan command (section
7.17.10 on page 861) to add the required port members as tagged or
untagged, use the management vlan command to remove the current
management VLAN, and then configure the newly created VLAN as the
new management VLAN.
