Chapter 17: Setting IPv4 and IPv6 Management

192

The Next Mask is a decimal number that represents the number of 
bits, from left to right, that constitute the network portion of the 
address. For example:



The decimal mask 16 is equivalent to the mask 255.255.0.0.



The decimal mask 24 is equivalent to the mask 255.255.255.0.

7. To assign a default gateway to the switch, enter an IPv4 address in the 

Default IP Gateway field. 

The IPv4 address is specified in the following format:

xxx.xxx.xxx.xxx

where x is a number from 0 to 255. There are four groups of 

numbers that are separated by periods.

For more information about the default gateway, see “IP Management 
Guidelines” on page 189.

8. Click Apply.

Use this procedure to assign the switch an IPv4 management address 
from a DHCP server. This procedure activates the DHCP client, which 
automatically queries the network for a DHCP server. The client also 
queries for a DHCP server whenever you reset or power cycle the switch.

When you use the web interface to assign an IPv4 address to the 
switch using DHCP, you lose connection with the switch. To 
maintain your connection with the switch, make sure you have a 
local connection to the switch when you assign an DHCP IP 
address.

To assign an DHCP IPv4 address, do the following:

1. Select the Management tab.

The Management tab is displayed. See Figure 64 on page 190.

2. From the Management tab, select IP.

3. Click the box next to the DHCP Address field.
