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 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, and 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.
The SIM commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following
table.
Command Parameters
enable sim
disable sim
show sim
{[candidates {<candidate_id 1-32>} | members {<member_id 1-
32>} | group {commander_mac <macaddr>} | neighbor]}
reconfig
{member_id <value 1-32> | exit}
config sim_group
[add <candidate_id 1-32> {<password>} | delete <member_id 1-
32>]
config sim
[{[commander {group_name <groupname 64> | candidate] |
dp_interval <sec 30-90> | hold_time <sec 100-255>}
download sim_ms
[firmware | configuration] <ipaddr> <path_filename> [members
<mslist> | all}

Each command is listed, in detail, in the following sections.
enable sim
Purpose
Used to enable Single IP Management (SIM) on the switch
Syntax

and functions will not function properly unless this function is
enabled.
Parameters None.
Restrictions Only
administrator-level users can issue this command.
Example usage:
To enable SIM on the switch:
DGS-3312SR:4#enable sim
Command: enable sim
