IP Configuration

Instruction Manual - NXA-ENET8-POE+
NOTE:
If you lose the management connection, make a console connection to the switch and enter show ip interface to determine the
new switch address.
Renewing DCHP
- DHCP may lease addresses to clients indefinitely or for a specific period of time. If the address expires or the
switch is moved to another network segment, you will lose management access to the switch. In this case, you can reboot the
switch or submit a client request to restart DHCP service via the CLI.
If the address assigned by DHCP is no longer functioning, you will not be able to renew the IP settings via the web interface. You
can only restart DHCP service via the web interface if the current address is still available.

Setting the Switch's IP Address (IP Version 6)
This section describes how to configure an IPv6 interface for management access over the network. This switch supports both
IPv4 and IPv6, and can be managed through either of these address types. For information on configuring the switch with an IPv4

Command Usage
IPv6 includes two distinct address types - link-local unicast and global unicast. A link-local address makes the switch
accessible over IPv6 for all devices attached to the same local subnet. Management traffic using this kind of address
cannot be passed by any router outside of the subnet. A link-local address is easy to set up, and may be useful for simple
networks or basic troubleshooting tasks. However, to connect to a larger network with multiple segments, the switch must
be configured with a global unicast address. Both link-local and global unicast address types can either be dynamically
assigned (using the Configure Interface page) or manually configured (using the Add IPv6 Address page).
An IPv6 global unicast or link-local address can be manually configured (using the Add IPv6 Address page), or a link-local
address can be dynamically generated (using the Configure Interface page).
Configuring the IPv6 Default Gateway
Use the System > IPv6 Configuration (Configure Global) page to configure an IPv6 default gateway for the switch.
The following table lists the options on this page:

Default Gateway
Sets the IPv6 address of the default next hop router to use when no routing information is known
about an IPv6 address.
• An IPv6 default gateway can only be successfully set when a network interface that directly
connects to the gateway has been configured on the switch.
• An IPv6 address must be configured according to RFC 2373
IPv6 Addressing Architecture
, using
8 colon-separated 16-bit hexadecimal values. One double colon may be used in the address to
indicate the appropriate number of zeros required to fill the undefined fields.
