Zone based firewalling is available in Cisco Packet Tracer 2800 routers with IOS 12.4(15)T1 and in new 2901/2911 ISR routers with IOS 15.1(4). This feature was introduced by Cisco in IOS 12.4(6)release.
The zone-member command seems to be only available on 2811 router's FastEthernet interfaces. It is not available on vlan interfaces of this router or in a 2911 router.
