Switch will not forward traffic with default configuration

TitleSwitch will not forward traffic with default configuration
  • No traffic being forwarded through the switch
  • Unable to communicate with devices through the switch
  • Unable to obtain IP address
  • EXOS patch 1-2
  • Default Configuration
This is a software defect and can be tracked via CR xos0064400.  "all_cast" flooding has been incorrectly disabled on all ports of the switch.  If broadcasts are not forwarded, basic switching functionality does not work like DHCP, ARP, etc.  If this problem is present the "disable flooding" command will be seen in the configuration for all ports:
disable flooding all_cast port 1
disable flooding all_cast port 2
disable flooding all_cast port 3
This issue has been resolved in EXOS Patch 1-5.


Re-enable all_cast flooding (normally the default):
enable flooding all_cast ports all
  • Even with patch1-5, if the switch is unconfigured, gets an DHCP address and valid DNS attributes, if it can resolve extremecontrol[.searchdomain] and connect to that Extreme Management Center (Netsight) it will disable flooding.
Additional notes
  • A switch with an existing configuration upgraded to EXOS patch 1-2 will not see this issue
