MultiSwitch 300 Version 2.0 Firmware


   1. The default of the associated MAC addresses filter has 
       been changed from '111111..11' binary to '0000..000'
     
       Example: 
       Define a custom filter for source ports 2 & 3 ...
       All the filters associated with the other source ports
       1,4,5,etc. will be zero.
    
    2. Non terminated ports (with no link) will be in Disabled 
       State - if the spanning tree is enabled. When the link 
       is connected the port moves to Blocking and the Spanning 
       Tree algorithm for that port/connection takes place.
    
       Disadvantage: after connecting a PC will take approx. 50 
       sec. until the port will be open (for default STP values).
       
       Advantage: protection from storms
    
    3. The state of the Spanning Tree (non forwarding) is reflected 
       by the filters associated with a MAC address/Connectivity 
       Matrix, etc..
      
       A bit corresponding to a port in non-forwrarding state will 
       be 0, i.e. no connectivity. Example: the connectivity matrix 
       of a switch with no ports connected (link off) and Spanning 
       Tree enabled will be blank ( no connectivity between ports) 
       regardless of the VLANs defined (if any !!).
    
    4. We added thresholds to the quantity of broadcast packets per 
       sec that may be forwarded to the management CPU (550 pps). 
       Above this limit the broadcasts forwarded to the Management 
       CPU will be disabled for at least 2 sec.
    
       We added thresholds to the quantity of Switch Address packets 
       per sec that may be forwarded to the management CPU (250 pps). 
       Above this limit the Switch Address packets forwarded to the 
       Management CPU will be disabled for at least 2 sec.
    
    5. Console : case insensitive, except passwords.
    
    6. In order to allow browsing(get-next) of the Learn Table 
       according to the Bridge MIB and/or Filter Table the LT is 
       cached locally. This adds a constant overhead, but allows a 
       better standard MIB reponse. At the same time new MAC 
       addresses appearence may be delayed.
    
    7. ARP table overflow. If the ARP table is full and we have a 
       new learn request, a random entry is deleted and the new 
       information is added. Previously, the new information was 
       discarded generating possible IP connectivity problems.
    
    8. Port Mirroring may be saved in the NVRAM.
    
    9. Firmware File name limit is increased to 50 characters.
    
    10. get-port-conf changed to get-port-cfg, but the old command 
        is still present
    
    11. Added CRC bytes to MIB II octets counts and RMON octets 
        statistics
    
    12. Reset (warm/cold) traps are received even if STP and BOOTP 
        are enabled.
    
    13. In-band and Out-of-band IP addresses may be in the same subnet. 
    
    14. Spanning Tree traps behaviour improved ..
    
    15. Root Trap is not generated, if there is a topology change but 
        the root is not practically replaced.
    
    16. Inactive addresses are no longer reported (in both SNMP access
        and console access ).  
    
    17. Spared 100K RAM
   
    18. MIB II IfAdmin set corrected
    
    19. Port_cfg & Stp_port cfg group commands
 
    20. Possible to have both the SLIP and the in-band IP address in 
        the same subn
