    2. Known Issues for Release v01.00.09

    2.1 Limitations with Flow Control

    The function of the switch has been optimized to provide flow control for most typicaloperating scenarios. However when ports are configured in half duplex mode, thisdevice can support back pressure (flow control for half duplex mode) for only up to 17ports.

    Please note that the flow control will work for all 48 ports in full duplex mode which is thetypical scenario.

    2.2 Intermittent SNMP Trap IssueOn a very infrequent basis, the switch is generating unsolicited 802.1X authenticationfailure traps.

    3. Issues Resolved in Release v01.00.09

    3.1 802.1x 802.1x authentication fail when using PEAP.

    In the earlier version of code, 802.1X setting of Force Unauthorized on ports waslost after reboot. This issue has been resolved in this version.

    In the earlier version of code there was a compatibility issue with Ciscos ACSserver. On setting a port in "Radius.None" authentication mode with Cisco ACSradius server, user with wrong/username password would erroneously getauthenticated on this port. This has now been resolved.

    3.2 ARPStatic ARP entry is lost after reboot the switch in earlier versions of code. This has beenfixed in this release.

    3.3 ACL ACL web page displayerror for Any radio button for mac address range and

    mask. Settings on create page were not being displayed on the mdofiy page.This is now fixed.

    ACL help web page displayerror format for MAC Address format, and VLAN IDrange. This has been corrected on the help page.
