Configuring IP Addressing
IP Configuration
Configure Multiple IP Addresses on a VLAN (Multinetting). The fol-
lowing is supported:
■ Up to 2000 IP addresses for the switch
■ Up to 32 IP addresses for the same VLAN
■ Up to 512 IP VLANs, that is, VLANs on which you can configure IP
addresses
■ Each IP address on a VLAN must be for a separate subnet, whether on the
same VLAN or different VLANs.
Syntax: [ no ] vlan < vlan-id > ip address < ip-address/mask-length >
[ no ] vlan < vlan-id > ip address < ip-address > < mask-bits >
For example, if you wanted to multinet VLAN_20 (VID = 20) with the IP
addresses shown below, you would perform steps similar to the following.
(For this example, assume that the first IP address is already configured.)
IP Address VID IP Address Subnet Mask
1st address 20 10.25.33.101 255.255.240.0
2nd address 20 10.26.33.101 255.255.240.0
3rd address 20 10.27.33.101 255.255.240.0
1. Go to VLAN 20.
2. Configure two additional
IP addresses on VLAN
20.
3. Display IP addressing.

If you then wanted to multinet the default VLAN, you would do the following:
