6. The CaS can be configured through the CS to become a MS.
After configuring one switch to operate as the CS of a SIM group, additional DES-3550 switches may join the group by either
an automatic method or by manually configuring the switch to be a MS. The CS will then serve as the in band entry point for
access to the MS. The CS’s IP address will become the path to all MS’s of the group and the CS’s Administrator’s password,
and/or authentication will control access to all MS’s of the SIM group.
With SIM enabled, the applications in the CS will redirect the packet instead of executing the packets. The applications will
decode the packet from the administrator, modify some data, then send it to the MS. After execution, the CS may receive a
response packet from the MS, which it will encode and send it back to the administrator.
When a CS becomes a MS, it automatically becomes a member of first SNMP community (include read/write and read only) to
which the CS belongs. However if a MS has its own IP address, it can belong to SNMP communities to which other switches in
the group, including the CS, do not belong.

following table.
