1-10 

z 

Re-authentication timer (reauth-period). The switch initiates 802.1x re-authentication at the 

interval set by the re-authentication timer. 

z 

RADIUS server timer (server-timeout). This timer sets the server-timeout period. After sending an 

authentication request packet to the RADIUS server, the switch sends another authentication 

request packet if it does not receive the response from the RADIUS server when this timer times 

out. 

z 

Supplicant system timer (supp-timeout). This timer sets the supp-timeout period and is triggered 

by the switch after the switch sends a request/challenge packet to a supplicant system. The switch 

sends another request/challenge packet to the supplicant system if the switch does not receive the 

response from the supplicant system when this timer times out. 

z 

Transmission timer (tx-period). This timer sets the tx-period and is triggered by the switch in two 

cases. The first case is when the client requests for authentication. The switch sends a unicast 

request/identity packet to a supplicant system and then triggers the transmission timer. The switch 

sends another request/identity packet to the supplicant system if it does not receive the reply 

packet from the supplicant system when this timer times out. The second case is when the switch 

authenticates the 802.1x client who cannot request for authentication actively. The switch sends 

multicast request/identity packets periodically through the port enabled with 802.1x function. In this 

case, this timer sets the interval to send the multicast request/identity packets. 

z 

Client version request timer (ver-period). This timer sets the version period and is triggered after a 

switch sends a version request packet. The switch sends another version request packet if it does 

receive version response packets from the supplicant system when the timer expires. 

In addition to the earlier mentioned 802.1x features, Switch 5500-EI is also capable of the following: 

z 

Checking supplicant systems for proxies, multiple network adapters, etc. (This function needs the 

cooperation of a CAMS server.) 

z 

Checking client version 

z 

The guest VLAN function 

 

  Note: 

H3C's CAMS Server is a service management system used to manage networks and to secure 

networks and user information. With the cooperation of other networking devices (such as switches) in 

the network, a CAMS server can implement the AAA functions and rights management. 

 

Switch 5500-EI checks: 

z 

Supplicant systems logging on through proxies 

z 

Supplicant systems logging on through IE proxies 

z 

Whether or not a supplicant system logs in through more than one network adapters (that is, 

whether or not more than one network adapters are active in a supplicant system when the 

supplicant system logs in). 

In response to any of the three cases, a switch can optionally take the following measures: 

z 

Only disconnects the supplicant system but sends no Trap packets.
