IP Addresses Window
This window appears when you choose Administration > IP Addresses on
the menu bar. You can also click here
to launch it. Use it to assign network addresses to VLANs and, for Catalyst
3550 switches, to create SVIs (switched virtual
interfaces) and routed ports.
Begin by selecting the device from the Host Name list. Then use these
tabs:
When you are done, click OK.
In the Interface Name column, you see the names of the VLANs and, for
Catalyst 3550 switches, the names of ports. To assign an IP address and subnet
mask to a VLAN or to a port or to modify an address and mask:
- Click the row of a VLAN or port.
- Enter an IP address in the IP Address cell.
- Expand the list of subnet masks in the Subnet Mask cell.
- Select a subnet mask from the list.
Note: If a non-3550 switch has more than one VLAN with an IP address,
only one at a time can be active. Use the Management
VLAN window to specify the active VLAN.
To create an SVI on a Catalyst 3550 switch:
- Click in the row of a VLAN that has an IP address and subnet mask.
- Check the box in the Routed cell.
To create a routed port on a Catalyst 3550 switch:
- Click in the row of a port that has an IP address and subnet mask.
- Check the box in the Routed cell.
- In the Default Gateway field, enter the IP address to which the device
will send traffic that contains an unknown address.
- In the Domain Name field, enter a name that identifies an administrative
region in the IP network. (You might need to ask your network administrator
for this information.) When network traffic contains no domain name, the name
you enter is appended to the name of the device, and the fully qualified name
is added to the device's host name table.
