Command Usage
• 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 “Enabling the SBC to Access Advanced Management
Tools” on page 74).
• 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 a management VLAN, first set up a new VLAN without
naming it (see “Creating VLANs” on page 284), add the required port
members as tagged or untagged (see “Adding Static Members to
VLANs (VLAN Index)” on page 287), remove the current management
VLAN (see “Creating VLANs” on page 284), and then set the newly
created VLAN as the new management VLAN on the Basic VLAN
Information page.
Command Attributes
Management VLAN
Type – The ECN330-switch acts as a Network Address Translator (NAT) for
management traffic, connecting and hiding the embedded nodes from the
Access Domain Management. The following interfaces (each configured
independently) are utilized:
• Internal – Internal Management VLAN is the gateway for the
embedded nodes (such as ECN330-switch, IP DSLAM, ESN108).
By default, it is configured through DHCP with an internal IP
