which an authentication client receives an initial IP address. For example:
which an authentication client receives an initial IP address. For example:
-> aaa avlan default dhcp 192.10.10.22
Telnet and Web browser clients will initially receive an IP address in this scope. (After authentication,
these clients may require a new IP address if they do not belong to the VLAN associated with this gate-

these clients may require a new IP address if they do not belong to the VLAN associated with this gate-
way address.)
