Onlythe last identified IPv4 address conflict is retained for display by a show command. Administrators may examine thein- memory logs or the output from a SYSLOG server to identify the historical IP address conflicts. If console loggingis enabled for traps, a message will appear on the console indicating that an address conflict has occurred. Email AlertingEmail alerting allows administrators to be notified regarding system events. Multiple email addresses can beconfigured. The system will attempt to resolve mail servers specified with a DNS FQDN immediately and, ifsuccessful, store the mail-server as an IP address. If a new IP address is subsequently assigned to the mail server, theoperator will need to re-assign the email address on the switch.Only the Mail User Agent functionality of RFC 4409 is implemented. The PowerConnect switch does not implementSMTP server functionality. 802.1x Monitor ModeMonitor mode is a special debug mode that assists network administrators in configuring new authentication servers.Users attempting to authenticate using the authentication server are always granted access when monitor mode isenabled. All interactions with the supplicant and the authentication server are logged.Administrators are cautioned against enabling monitor mode in a deployed network where 802.1x users may gainaccess to sensitive network resources. Time Controlled ACLsTime controlled ACLs allow administrators to apply ACLs based on the time of day. Both periodic and absolute timeperiods may be configured.Administrators are cautioned that invalid (overlapping) periodic entries within a time range will cause the time range tonot be applied. Administrators are advised to test their periodic entries and validate that they become active as expectedbefore deploying the time ranges in a production network. Administrators can check if a time range is active by usingthe show time-range command.It is recommended to enable ACL logging to ensure notice of ACL activation and de-activation. SNTP over IPv6SNTP operates over IPv4 and IPv6 and may be configured using IPv4 or IPv6 addresses or DNS. Strong PasswordsThe strong passwords feature allows administrators to specify that switch administrator passwords meet certaincharacteristics considered to enhance network security.Administrators are advised that the minimum character classes configuration must be enabled (value equal to 1 orgreater) along with enabling the strong password feature before the other minimum character class configurations areenforced. These character class configuration are: Minimum number of uppercase letters. Minimum number of lowercase letters. Minimum number of numeric characters. Minimum number of special charactersThe password strength restrictions do not apply to users configured for the internal authentication server.
