IP interfaces

On the routing switches, IP addresses are associated with individual VLANs. By default, there is a single VLAN (Default_VLAN) on the routing switch. In that configuration, a single IP address serves as the management access address for the entire device. If routing is enabled on the routing switch, the IP address on the single VLAN also acts as the routing interface.

Each IP address on a routing switch must be in a different subnet. You can have only one VLAN interface in a given subnet. For example, you can configure IP addresses and on the same routing switch, but you cannot configure and on the same routing switch.

You can configure multiple IP addresses on the same VLAN.

The number of IP addresses you can configure on an individual VLAN interface is 32.

You can use any of the IP addresses you configure on the routing switch for Telnet, Web management, or SNMP access, as well as for routing.


All devices support configuration and display of IP address in classical subnet format (example: and Classless Interdomain Routing (CIDR) format (example: You can use either format when configuring IP address information. IP addresses are displayed in classical subnet format only.
