• seconds - Time in seconds that the switch remains in the quiet state following a failed authentication exchange with the client. (Range: 0- 65535 seconds) Default Configuration Each timer has a default as follows: • quiet-period: 60 seconds • tx-period: 30 seconds • supp-timeout: 30 seconds • server-timeout: 30 seconds Command Mode Interface Configuration (Ethernet) mode User Guidelines Change the default value of the 802.1X/AAA timers only to adjust for unusual circumstances, such as unreliable links or specific behavioral problems with certain clients or authentication servers. Changing these values may result in RADIUS server timeouts, failed authentications or switch behavior that is not responsive to 802.1X clients, potentially including denial of network access. It is strongly recommended that the authentication server be present within the local site to ensure access to the network. Configuring the switch to use a remote Active Directory or other authentication server operating over a congested or unreliable link will not give local 802.1X clients a responsive experience and may deny 802.1X clients access to the network. The RADIUS server relies on the DNS service to resolve RADIUS host names. A slow to respond DNS server will cause delays in processing of 802.1X client authentications. An unresponsive DNS server will deny network access to 802.1X clients. It is strongly recommended that a local DNS server be used whenever possible. Configuring the switch to use a remote Active Directory or other DNS server operating over a congested or unreliable link will not give local 802.1X clients a responsive experience and may deny 802.1X client access.
