A customer's wireless network VLAN is rapidly exhausting IP addresses. The customer insists that the network range should not change, but he wants to address growing network needs. Due to poor…

Creating a new SSID with a different name mapped to the same existing interface does not add any additional IP addresses and does not resolve the exhaustion problem.

Mapping the SSID to a larger interface implies assigning a different, larger subnet, which directly contradicts the requirement that the network range must not change.

Creating an interface group on the WLC and adding the existing interface plus one or more new interfaces to that group, then mapping the SSID to the group, allows the controller to distribute client DHCP requests across all member interfaces - expanding total IP address capacity without altering the original network range.

Adding an expanded interface and remapping the SSID would replace the existing subnet with a new one, violating the constraint that the network range must remain unchanged.
