Defects This section lists closed and opened defects in Multi-Service IronWare R04.2.00 releases for the TurboIron 24X. Closed Defects in IronWare R04.2.00b None. Closed Defects in IronWare R04.2.00a Defect ID: DEFECT000308117 Technical Severity: Medium Summary: The TurboIron still learns MAC addresses even with mac-learn-disable configured. Feature: TI L2 Forwarding Function: Transparent FW Mode Reported In Release: FI TI 04.2.
Feature: Mac Authentication Reported In Release: FI TI 04.2.
Feature: TI ACL Reported In Release: FI TI 04.2.00 Function: ACL Deny Logging Probability: Medium Defect ID: DEFECT000298123 Technical Severity: Medium Summary: If a mac-filter is configured on a port and then 802.1x attaches another mac-filter on the same port, then 802.1x does not allow the original mac-filter to be removed. Symptom: Removal of mac-filters applied before 802.1x authentication is not smooth when 802.1x itself attaches a mac filter on that port. Workaround: Disable 802.1x on the port.
