Firmware  v2.5.0 build 67 for DAS-4672DC chassis IP DSLAM

Release notes file.


The following bugs are fixed (in comparison with version 2.0.2 build 134):

1. Can't support up to 384 ACL Deny

2. ifTable.ifSpeed should be 0 if ifTable.ifOperStatus is down

3. Change PVC service type (from PPPoE+static-IP to PPPoE) will delete DHCP transactions on different PVC of this port

4. CLI "status nc show" standby NC's operational state is down (DAS-4672 with two NC modules)

5. Static IP base does not be loaded when config file is v2.4.0 and software version is v2.5.0

6. Add a DHCP+PPPoE PVC with IP limit 64 will let SNMP daemon hang

7. Routed mode, new learned MAC will cause NE to crash

8. PPPoE session connection issue

9. DSLAM doesn't support the join packet of IGMPv1 transforming into IGMPv3.
There's join packet forwarding to DSLAM (The IGMP join message is presented in the "stateful" functionality), but it's not forwarded to the IGMP Server 
(The join packet of IGMPv1 will be dropped).

10. Suppose MAC #A is the MAC address the NE reserves for RFC2684 routed mode. Whenever the NE learns a MAC address #A on port 1 which is not configured as RFC2684 routed mode, the LCT will show the error message "SNMP-Fail to Query" if he/she sets the state of MAC #A to be "ACL Permit" via LCT.

11. Fixed the ARP adding failure.

12. To let login be presented after system time, the NE system will delay 5 seconds before displaying the Slave NC's CLI login (DAS4672 IPDSLAM only)

13. Rate limiting for different type packets (to protect CPU)

14. "Update" function of SNTP (Simple Network Time Protocol)  doesn't work for both CLI & LCT

15. The NE cannot launch the IGMP report between host with different MCAU VLAN and router

16. Various PVC / MAC limit restriction bugs.

17. Some PVCs on LC #A which are preconfigured to be disabled may be enabled whenever the LC #A is rebooted.

18. Some MCAU (xDSL Multicast Channel) setting on LC #A which is preconfigured to be disabled may be enabled whenever the LC #A is rebooted.

19. Can not enable PVC when LC is not inserted

20. Work around various bugs of being out of memory for redundancy (DAS4672 only)


New features (in comparison with version 2.0.2 build 134):

1. Enlarged history alarm table from 512 to 2000

2. Supports multiple DHCP PVCs per ADSL port

3. Supports multiple PPPoE PVCs per ADSL port

4. Additional service types are added as PPPoE + Static-IP and PPPoE + DHCP

5. The IP limit per PVC is changed from 8 to 64

6. The MAC limit per PVC is changed from 8 to 64 (The limited setting value 1~16,32,40,48,56,64 is caused by hardware limitation)

7. Save ADSL line standard (multiple selection) into ADSL line profile

8. MAC spoofing for UGE

9. Packet filtering

10. IGMP snooping for normal leave/immediate leave

11.IGMP v3 lite: Configurable version type of the IGMP packets launched by the NE no matter what version of IGMP packet it receives.
Only supporting the multicasting of packet based on its associated multicast MAC address. The NE does not support the multicasting of packet according to 
either its multicast IP address or its source IP address.

12. FDB aged mode

13. Static FDB

14. Single IP management, cascading IP/Netmask setting

15. Default configuration file: If the config.cfg is absent or is corrupted, the NE will read and check default.cfg and try to rebuild the default configuration.

16. LCT Power module status: Displaying the status of power module on the "rack view" of LCT.

17. Alarm Output configuration/status
