Please log in for more thread options i've been playing around with vlans. i simply configured a vlan with an adress range, that's not i use yet. "interface intf3 vlan3 logical" it seems to work: interface vlan3 "intf3" is up, line protocol is up Hardware is i82559 ethernet, address is 0002.b3ec.4ce8 IP address 192.168.100.1, subnet mask 255.255.255.0 MTU 1500 bytes, BW 10000 Kbit half duplex 0 packets input, 0 bytes 1 packets output, 46 bytes i attached a laptop to the physical if and configured my nic in the same subnet, allowed telnet from that host. i can not ping, telnet or anything to the pix. i do debug, capture , logg via console and don't see a single packet arriving at the pix. any ideas | |||||||||||||||||||

Please log in for more thread options That's correct. The PIX expects any packet coming to the interfacec intf3 to be tagged accordingly to 802.1q protocol. Basically you can think about the intf3 of the PIX like a trunking port of a switch I don't think your laptop can manage trunk link on its interface. Maybe some linux boxes with specific software/kernel options. So take out a switch with trunking ports and connect that port to intf3. HTH Alex. >
