Discovering McDATA and Connectrix Switches through a Proxy with SNMP
NOTE: Discovering McDATA or Connectrix switches through a proxy using the SNMP protocol
does not let you manage or access information about zones, zone sets or zone aliases.
You can use this option with EMC Connectrix Manager and EFC Manager to contact the switch.
IMPORTANT: Provide the SNMP credentials in the WBEM settings section on the System
Protocol Settings page (Options > Protocol Settings > System Protocol Settings). Only the
WBEM default credentials are passed from HP SIM to HP Storage Essentials. Any default
credential information you set up in regards to SNMP is not passed from HP SIM to HP
Storage Essentials.
1. Change the discovery setting for McDATA and Connectrix switches to SNMP following the steps
in ”Changing the Discovery Settings” on page 43.
2. Verify the following on the proxy and the switches accessible from the proxy:
• The SNMP agent is enabled.
• The read-only community string is configured.
3. To discover the proxy, enter the following information in HP SIM:
• IP address or system name of the EFC Manager or Connectrix Manager you want to
discover.
• User name. The default user name, which is public (the read-only community string). This is
the user name of the proxy.
• Enter anything as a password; HP SIM does not allow an empty password field.
4. Make sure there are no port conflicts for receiving SNMP traps. When the management server is
configured to contact the proxy by SNMP, it receives events from the proxy in the form of SNMP
traps. By default, the management server uses port 162 to receive SNMP traps. If another
software package is using that port, the management server is unable to receive the traps. For
information about changing the port, see ”Changing the SNMP Trap Listener Port and
Community String for Switches Discovered with SNMP” on page 46.
5. Set up the proxy to send traps to the correct port. When you are using the SNMP setting to
discover a proxy, you must configure the SNMP agent on the proxy manager to send traps from
all switches managed by the proxy to the management server using the port you selected. For
more information, see the documentation for your proxy.
