Configuring System Settings
The System Settings page enables you to configure information that identifies the 
switch within the network.
To configure system settings:
STEP 1Click Administration > System Settings in the navigation window.
The System Description is hard-coded in the firmware.
STEP  2Enter the parameters:
•System Location—Description of the physical location of the switch.
•System Contact—Contact person for the switch.
•Hostname—Administratively-assigned name for this managed node. By 
convention, this is the fully-qualified domain name of the node. The default 
hostname is switch concatenated with the last 6 hex digits of the MAC 
address of the switch. Hostname labels contain only letters, digits and 
hyphens. Hostname labels cannot begin or end with a hyphen. No other 
symbols, punctuation characters, or blank spaces are permitted.
NOTE: You can check the Set Default field to return the hostname to the 
default.
STEP  3Click Apply. The changes are saved to the Running Configuration.

Management Interface
Switch management interface enable access to the web-based switch 
configuration utility from a management station on the network. The switch 
supports configuration of a management VLAN that segregates the management 
traffic from other traffic on the switch.
The management interface can be configured with an IPv4 address or with an IPv6 
address. The addresses can be configured statically or they can be obtained 
through DHCP/BOOTP servers.
Se e the following topic s for more information on the configuration pages available 
in the Administration > Management Interface menu:
•Configuring an IPv4 Management Interface
•Configuring an IPv6 Management Interface
•Viewing and Adding IPv6 Neighbors
Configuring an IPv4 Management Interface
You can use the IPv4 Interface page to configure the management VLAN and IPv4 
address.
To configure the IPv4 management interface:
STEP 1Click Administration > Management Interface > IPv4 Interface in the navigation 
window.
STEP  2Select a management VLAN from the list.
A port must be a member of the management VLAN to gain access to the web-
based switch configuration utility. By default, VLAN 1 is configured as the 
management VLAN and all switch ports are configured as members of VLAN 1. 
At least one port must be a member of the management VLAN. The Member Ports 
list displays all current members of the selected management VLAN.
Note that when you change the management VLAN, you must reassign any 
members of the previous management VLAN to the new VLAN to continue their 
management access.

STEP  3Select one of the following options for the IP Address Type:
•DHCP—The management interface obtains its IPv4 address from a DHCP 
server. DHCP is enabled by default and the switch requests an IP address 
from a DHCP server. If it is unable to get the IP address from a server, the 
switch falls back to the factory default static IP address. The System LED 
flashes continuously and the switch keeps trying to get its IP address from a 
DHCP server. If you set a static IP address, the LED stops flashing. The 
factory default static IP address is 192.168.1.254/24, with a default gateway 
IP address of 192.168.1.1.
•BOOTP—The management interface obtains its IPv4 address from a BOOTP 
server.
•Static—The management interface IPv4 address assigned in the IP 
Address field.
If the IP Address Type is set to Static, specify the following:
-IP Address—Enter an IPv4 address.
-Mask—Enter a 32-bit network mask (for example, 255.255.255.0).
Or select Prefix Length and specify the number of bits (0–32) that make 
up the network prefix (for example, 24).
-Default Gateway—Select User Defined and specify the default 
gateway IP address for management packets.
Or select None to prevent management packets from being transmitted 
outside the subnet.
•Operational Default Gateway—The current default gateway in use.
•Renew DHCP—Select Renew DHCP and click Apply to send a request to 
the DHCP server for a new IP address and related parameters.
STEP  4Click Apply. Your changes are saved to the Running Configuration.
!
CAUTIONChanging the management IP address and IP Address Type terminates the current 
management session. Changing the Management VLAN and its port memberships 
might disrupt your communication with the switch and thus might terminate the 
current management session.

Configuring an IPv6 Management Interface
Use the IPv6 Interface page to enable access to the web-based switch 
configuration utility over IPv6. You can configure the switch to dynamically learn its 
IPv6 addresses and you can configure IPv6 addresses statically.
To enable IPv6 management access:
STEP 1Click Administration > Management Interface > IPv6 Interface in the navigation 
window.
The Interface field shows the VLAN ID of the management VLAN.
STEP  2Configure the following settings:
•IPv6 Mode—Select to enable IPv6 management access.
•IPv6 Address Auto Configuration—Select to enable the switch to auto-
configure its link-local address(es) in EUI-64 format, using the MAC address 
of the port(s) for the link-local part of the address. The switch listens to router 
advertisements to detect and autoconfigure the global part of the address.
•DHCPv6—Select to enable the switch to obtain its IPv6 address(es) from a 
DHCPv6 server.
•IPv6 Gateway—Enter the link local address of the IPv6 router where the 
switch should send IPv6 packets destined for a device outside the subnet.
STEP  3Click Apply. Your changes are saved to the Running Configuration. You can click 
Cancel to clear the changes.
Adding IPv6 Addresses
The IPv6 Address table lists static addresses currently configured on the switch. It 
contains the following fields:
•IPv6 Address—IPv6 address in IPv6 global address format. 
The table includes the default IPv6 address. The switch creates this 
address automatically by inserting standard byte values into its 48-bit MAC 
address to create a 64-bit IPv6 address in EUI-64 format, as described in 
RFC 3513.

•DAD Status—The Duplicate Address Detection status. When you configure 
an IPv6 address on the switch, before the switch actually assigns the 
address, it performs neighbor discovery to detect if that address is already 
in use on the network.
-If the address is already in use, its DAD status is True, and the address is 
not usable for management access.
-If the address is found to be unique, its DAD status is False, and the 
address can be used for management access. 
You can configure multiple IPv6 addresses. Each address should have a different 
prefix so that the switch can be managed from stations on different subnets. When 
a route to one subnet fails, the switch can be managed from another subnet.
To add a static IPv6 address:
STEP 1Click Add.
STEP  2Enter an IPv6 address followed by a slash (/) and the prefix length.
STEP  3Select EUI-64 if the address conforms to the EUI-64 format, whereby the first 
three to five octets are the Organizationally Unique Identifier (OUI) and the 
remaining octets are a unique assigned address.
STEP  4Click Apply and then click Close. Your changes are saved to the Running 
Configuration.
IPv6 Default Router Table
When IPv6 management is enabled, the switch uses the IPv6 neighbor discovery 
process to identify the default router for communicating with devices outside the 
local IPv6 subnet. The default router in IPv6 networks is similar in function to the 
default router in IPv4 networks.
The IPv6 Default Router table lists the default router IP address for each IPv6 
management address. A default router address consists of the link-local address 
of the IPv6 interface on the subnet.

Viewing and Adding IPv6 Neighbors
When IPv6 management is enabled, the switch identifies IPv6-enabled devices on 
attached links. The switch supports the discovery of up to 1,000 dynamic IPv6 
neighbors and supports the static configuration of IPv6 neighbors. 
The IPv6 Neighbors page lists dynamically discovered and statically configured 
neighbors, and enables adding static hosts.
To view the IPv6 neighbor Table, click Administration > Management Interface > 
IPv6 Neighbors in the navigation window.
The IPv6 Neighbor Table displays the following fields for each dynamic entry:
•IPv6 Address—IPv6 address of neighbor.
•MAC Address—MAC address of the neighbor.
•State—State of the neighbor. The following are the states for dynamic 
entries:
-Reachable—Confirmation was received within a preconfigured interval 
that the forward path to the neighbor is functioning properly. While in the 
Reachable state, the device takes no special action as packets are sent.
-Delay—More time has elapsed than a preconfigured interval since the 
last confirmation was received that the forward path was functioning 
properly. 
•Age Updated—The time in seconds that has elapsed since an entry was 
added to the cache.
•Type—Neighbor discovery cache information entry type (static or 
dynamic). 
You can click Clear Dynamic Neighbors to clear the table. 
Adding Static IPv6 Neighbors
The switch supports up to 16 static IPv6 neighbor entries. To add a static 
neighbor:
STEP 1Click Add.
STEP  2Enter an IPv6 global address (not including a prefix length).
STEP  3Enter the MAC address of the neighbor.
