Changing IP Information
You can assign and change the IP information of your switch in the following
ways:
Using the setup program, as described in the release notes
Manually assigning an IP address, as described in this section
Using Dynamic Host Configuration Protocol (DHCP)-based autoconfiguration, as
described in this section
----------------------------------------------------------------------------
----
Caution Changing the switch IP address ends any CMS, Telnet, or Simple
Network Management Protocol (SNMP) session. To restart your CMS session,
enter the new IP address in the browser Location field (Netscape
Communicator) or Address field (Internet Explorer). To restart your CLI
session through Telnet, follow the steps described in the "Accessing the
CLI" section.
----------------------------------------------------------------------------
----
----------------------------------------------------------------------------
----
Note If you enabled the DHCP feature, the switch assumes you are using an
external server for IP address allocation. While this feature is enabled,
any values you manually enter (from the CMS or from the ip address command)
are ignored.
----------------------------------------------------------------------------
----
Manually Assigning and Removing Switch IP Information
You can manually assign an IP address, mask, and default gateway to the
switch. The mask identifies the bits that denote the network number in the
IP address. When you use the mask to subnet a network, the mask is then
referred to as a subnet mask. The broadcast address is reserved for sending
messages to all hosts. The CPU sends traffic to an unknown IP address
through the default gateway.
Beginning in privileged EXEC mode, follow these steps to enter the IP
information:
Command Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
interface vlan 1
Enter interface configuration mode, and enter the VLAN to which the IP
information is assigned. VLAN 1 is the default management VLAN, but you can
configure any VLAN from IDs 1 to 1001.
Step 3
ip address ip_address subnet_mask
Enter the IP address and subnet mask.
Step 4
exit
Return to global configuration mode.
Step 5
ip default-gateway ip_address
Enter the IP address of the default router.
Step 6
end
Return to privileged EXEC mode.
Step 7
show running-config
Verify that the information was entered correctly by displaying the running
configuration. If the information is incorrect, repeat the procedure.
Use the following procedure to remove the IP information from a switch.

Subject: 3500 xl switch problem [7:12705]
Hello Everyone!
I changed the management VLAN of a 3500 switch thorugh the
browser-based cisco cluster management suite (CMS). By default the
switch IP address belongs to the management VLAN which is VLAN 1. Only
one vLan can be adminstratively active at the same time. By changing to
a newly created vlan I have lost the chance to manage the default vlan.
can't no longer console or access via the assigned IP address.
Thanks in advance if anyone knows anything about this!
Angel
