Hey everyone, I was wondering if someone could help me. I am trying to implement 801.x port security in my network. In our switch ports we have an IP AVAYA phone connected and a workstation connected to the IP phone. I enable dot1x authentication on the ports specifying the data vlan and the voice vlan. I configure the avaya phone 1608 in pass-thru mode, so that the authetication is forwaded to the PC. Supposedly, the phone would be able to connect without any authentication but it doesn't! I can't communicate with the dhcp server to get an ip:
Is there a way I can exclude any authentication on the voice VLAN but implement the dot1x for the data vlan on the same port? I would like to have authentication only for the workstation attached to the phone...\
In multiple-hosts mode, you can attach multiple hosts to a single 802.1X-enabled port. Figure 39-4 shows 802.1X port-based authentication in a wireless LAN. In this mode, only one of the attached clients must be authorized for all clients to be granted network access. If the port becomes unauthorized (re-authentication fails or an EAPOL-logoff message is received), the switch denies network access to all of the attached clients. In this topology, the wireless access point is responsible for authenticating the clients attached to it, and it also acts as a client to the switch.
With multiple-hosts mode enabled, you can use 802.1X authentication to authenticate the port and port security to manage network access for all MAC addresses, including that of the client.
