By default, PowerConnect switches process and respond to Cisco CDP packets. However, in networks where this capability is not desirable or other Cisco proprietary packets are flooded over the network, the administrator can disable flooding of Cisco link local protocols.
  • Page 8: Iscsi Optimization

    Detection of Dell EqualLogic arrays is keyed on receipt of the mandatory System Description TLV in the LLDP packet. Disabling LLDP will effectively disable Dell EqualLogic array detection. Dell EqualLogic arrays are required to be upgraded to firmware 5.0.2 or later in order to use the iSCSI Optimization feature.

Only the last identified IPv4 address conflict is retained for display by a show command. Administrators may examine the in- memory logs or the output from a SYSLOG server to identify the historical IP address conflicts.
