4.2.2 Configuring the network environment

If you set up firewalls between the Management Server and ETERNUS Disk storage system, set the following port numbers so as to allow transmissions to pass the firewalls.

Port number/Protocol	Communication start direction	Function
161/udp	From Management Server to ETERNUS Disk storage system	Configuration management, performance management, and polling
162/udp	From ETERNUS Disk storage system to Management Server	Fault management
1372/tcp (*1)	From Management Server to ETERNUS Disk storage system	Configuration management (For ETERNUS DX80 S2/DX90 S2, ETERNUS DX400 S2 series, ETERNUS DX8000 S2 series) Performance management (For ETERNUS DX80 S2/DX90 S2, ETERNUS DX400 S2 series, ETERNUS DX8000 S2 series) Advanced Copy (For ETERNUS DX80 S2/DX90 S2)
50002/tcp	From Management Server to ETERNUS Disk storage system	Advanced Copy (For ETERNUS DX80 S2/DX90 S2)
1999/tcp (*2)	From Management Server to ETERNUS Disk storage system	Configuration management Advanced Copy (For ETERNUS DX60/DX60 S2/DX80/DX90)
22/tcp	From Management Server to ETERNUS Disk storage system	Configuration management (For ETERNUS DX80 S2/DX90 S2, ETERNUS DX400 S2 series, ETERNUS DX8000 S2 series) Performance management (For ETERNUS DX80 S2/DX90 S2, ETERNUS DX400 S2 series, ETERNUS DX8000 S2 series)
23/tcp	From Management Server to ETERNUS Disk storage system	Configuration management (For ETERNUS DX60/DX60 S2/DX80/DX80 S2/DX90/DX90 S2, ETERNUS DX400 S2 series, ETERNUS DX8000 S2 series)

*1: For Maintenance-Secure connection
*2: For Maintenance connection

Express uses SNMP to register ETERNUS Disk storage system. Therefore, before registering devices, it is required to start SNMP Agent of ETERNUS Disk storage system. ETERNUS Disk storage system that has no SNMP Agent started cannot be registered.

Check the network environment, access privileges and settings of communication mode between Management Server and ETERNUS Disk storage system. If either communication mode of the Management Server or the ETERNUS Disk storage system is set to "Full (full duplex)", do not set the other to "Auto Negotiation".
Refer to the manual for each ETERNUS Disk storage system and check the network environment settings.

Point

The telnet connection and the Maintenance connection should be available on the ETERNUS Disk storage system.
