The invention enables a client device that does not support IEEE 802.1X authentication to access at least some resources provided through a switch that supports 802.1X authentication by using dynamic authentication with different protocols. When the client device attempts to join a network, the switch monitors for an 802.1X authentication message from the client device. In one embodiment, if the client fails to send an 802.1X authentication message, respond to an 802.1X request from the switch, or a predefined failure condition is detected the client may be deemed incapable of supporting 802.1X authentication. In one embodiment, the client may be initially placed on a quarantine VLAN after determination that the client fails to perform an 802.1X authentication within a backoff time limit. However, the client may still gain access to resources based on various non-802.1X authentication mechanisms, including name/passwords, digital certificates, or the like.

Enabling dynamic authentication with different protocols on the same port for a switch

A facility for proxying network traffic between a pair of nodes is described. The facility receives packets traveling between the pair of nodes that together constitute a  network connection. For each packet of the connection that is part of a transport protocol setup process, the facility updates a representation of the status of the setup process to reflect the packet, and forwards the packet to its destination without proxying the packet. For each packet of the connection that is subsequent to the setup process, the facility proxies the contents of the packet to the packet's destination.

A facility for proxying network traffic between a pair of nodes is described. The facility receives packets traveling between the pair of nodes that together constitute a distinguished network connection. For each packet of the connection that is part of a transport protocol setup process, the facility updates a representation of the status of the setup process to reflect the packet, and forwards the packet to its destination without proxying the packet. For each packet of the connection that is subsequent to the setup process, the facility proxies the contents of the packet to the packet's destination.

A facility in a single manager computer system for managing properties for a plurality of managed computer systems is described. The facility reiteratively receives new managed properties for an identified managed computer system. In response, the facility delivers the received new managed properties to the identified managed computer system.
