5500 not enough IP for clients

[Tony WONG]

the dhcp 200 IPs pool is used up, some wifi clients should leave but occupy the IPs

it can be solved by shortening the lease time (10hours) but the colleagues have to reconnect again.

is there any way to release the IP?  not to wait for expiry time

wlan, enable session timeout?

Thanks a lot.

To configure a DHCP timeout value, use the config dhcp timeout command. If you have configured a WLAN to be in DHCP required state, this timer controls how long the WLC will wait for a client to get a DHCP lease through DHCP.

we use 15 min lease time for wireless users in our campus environment :)

Hi,

Yes it can be solved shortening the lease time, 15-20 min lease time is enough, if you are short of IPs
