CHAPTER 2 Setup
Note:
z
If you want to use a switching hub that supports a loop guard function
(such as the spanning tree protocol and domain separation) as an external
switch, suppress the loop guard function by disabling [Spanning Tree
Protocol] for the port for connection between the switching hub and the
main unit or by turning on [Domain Separation].
z
The MMB transmits packets in communication of the following types:
NTP, alarm e-mail, REMCS, and SNMP trap. If both a physical IP
address and a virtual address are set for the MMB, the IP address of the
packet sender becomes the physical IP address of the MMB.
Under the following conditions, firewall, mail, and other servers must be
configured such that the packets with the physical IP addresses of
MMB#0 and MMB#1 can pass through:
- The destination server is an external server outside the firewall.
- IP addresses are restricted by the mail server used.
Also, if the REMOTE MAINTENANCE port is used with the PRIMEQUEST 580A/
540A under the above conditions, the servers must be configured such that the
packets with the IP addresses for REMOTE MAINTENANCE can pass through.
Remarks:
z
The physical IP addresses of the MMBs are also used for linkage with
PRIMECLUSTER.
z
If REMCS connection is involved, the connection method explained
below is used. For details, see Chapter 6, "REMCS" in the
PRIMEQUEST 580A/540A/520A/500/400 Series Reference Manual:
Basic Operation/GUI/Commands (C122-E003EN).
- Internet connection:
The REMCS ports are connected to an external switching hub or to the
center via the firewall from the external switch of the management
port.
- P-P connection:
The REMCS port of each MMB (MMB#0 and MMB#1) is directly
connected to the dial-up router.
