553-3001-225 Standard 1.00 May 2006
In a standard CS 1000 installation, the SMC is in the path of traffic between
the Intranet and the protected subnets so that all traffic flows through the
SMC.
IP connectivity
LAN ports
The SMC supports six 10/100/1000 Base-TX (copper) ports. Each port must
be on a separate subnet and the management and intranet networks must
always be present.
For integration of the SMC into optical networks or Multi-link Trunking
(MLT) networks in which more than a single port is used for a logical trunk,
an additional switch device is required to work in tandem with the SMC. The
switch interfaces with the SMC using a copper port and employs additional
ports on the switch for either the fiber interface conversion or multiplexing.
In this type of configuration, consider the additional switch and the SMC to
be a single unit. If either the switch or the SMC fails, it is comparable to a
single SMC device failure.
