       2.0  Change History
       --------------------


            AOS 20.1.2.2 [Released July 2004]:

            Fixes:
            - When a  SAVE is performed via BBI on a Factory Default GbESM, it 
              does not change the 'Next Boot Configuration Block Selection' to
              Active.
            - SNMP MIB walk fails - general error is displayed.
            - When Management Processor is stressed over an extended period
              the GbESM may reboot.
            - When VLAN is disabled, it is not saved through a reset. 
            - When telneting from the GbESM to another device, the characters are 
              repeated. 
            - When restarting the switch using Full POST (diagnostics), intermittent 
              0x1d, 0x41, 0x43 and 0x45 test failures may occur.
            - When telneting from the GbESM to another device, the password 
              is displayed in clear text.
            - When factory defaulted, the default IP address of the GbESM does not
              reflect the slot in which the switch is installed.
            - If the uplink trunk with L2 Trunk Failover enabled consists of 3 or 4 
              ports and all links are dropped simultaneously, then the GbESM may 
              not disable the INT ports as expected. 

            Enhancements:
            - Link state changes during boot process are minimized.           
            - New CLI message reminds the user that VLAN 4095 traffic cannot be
              mirrored to any external port.
            - Radius Authentication enhanced to interoperate with CiscoSecure 
              ACS 3.2 for Solaris


            AOS 20.1.1.0  [Released April 2004]:
            
            Changes:
            - Default INT Port configuration changed - ports have tagging enabled 
              and are members of VLAN 1 and 4095
            - Default MGT Port configuration changed - ports have tagging enabled
            - Link failover optimization for link aggregation
  
            Fixes:
            - When configured, the OSPF default route is not used 
            - When a default gateway for IP IF 128 is configured, server blade traffic 
              may utilize the wrong gateway
            - When 4 gateways are configured, the GbESM may only use 2 of them
            - Hashing algorithm for server load balancing metric hash does not 
              balance the traffic correctly
                
            Enhancements:
            - Four GbESM support 
            - L2 Trunk Failover (network adapter teaming support)
            - VRRP Hot-Standby (network adapter teaming support)
            - Serial-over-LAN support
            - Link Aggregation Control Protocol (LACP)
            - Configurable Trunk Hash algorithm 
            - Port Fast Forwarding
 
            AOS 20.0.1.3: [Released October 2003]

            - TCP session may timeout if a single link of a trunk group 
              is disconnected	  	         
		
            AOS 20.0.1.2 [Released September 2003]

            - Default STP configuration changed - Default STP setting for
              internal ports (INT1-INT14) is OFF
            - IBM Remote Deployment Manager and PowerQuest DeployCenter do
              not complete successfully
