The tunneling mechanism uses the ISATAP mechanism. This protocol treats the
IPv4 network as a virtual IPv6 local link, with mappings from each IPv4 address to a
link local IPv6 address.
The switch detects IPv6 frames by the IPv6 Ethertype.
IP Addressing
The switch operates as a Layer 2 VLAN-aware switch, and has no routing
capabilities. The 200 Series switches do not have layer 3 capabilities.
IP Addressing
The switch has a single IP address in the management VLAN. This IP address and
the default gateway can be configured with a static IP address, or by DHCP. The
static IP address and default gateway are configured on the IPv4 Interface Page.
The switch uses the default gateway, if configured, to communicate with devices
that are not in the same IP subnet as the switch. By default, VLAN 1 is the
management VLAN, but this can be modified. The switch can only be reached at
the configured IP address through its management VLAN.
NOTE All the IP addresses configured or assigned to the switch are also referred as
Management IP addresses in this guide.
Defining an IPv4 Interface
To manage the switch by using the web-based switch configuration utility, the
IPv4 switch management IP address must be defined and known. The switch IP
address can be manually configured or automatically taken from a DHCP server.
To configure the IPv4 switch IP address:
STEP 1 Click Administration > Management Interface > IPv4 Interface. The IPv4
Interface Page opens.
STEP 2 Enter the values for the following fields:
• Management VLAN—Select the Management VLAN used to access the
switch through telnet or the Web GUI. VLAN1 is the default Management
VLAN.
• IP Address Type—Select one of the following options:
- Dynamic—Discover the IP address using DHCP from the management
VLAN.
