DES-3526 Layer 2 Fast Ethernet Switch
2. CS’s must change their role to CaS and then to MS, to become a MS of a SIM group. Thus the CS cannot directly be
converted to a MS.
3. The user can manually configure a CS to become a CaS.
4. A MS can become a CaS by:
a. Being configured as a CaS through the CS.
b. If report packets from the CS to the MS time out.
5. The user can manually configure a CaS to become a CS
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-3526 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 back to the administrator.
When a CS becomes a MS, it automatically becomes a member of the 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 100-300>}
download sim_ms
[firmware | configuration] <ipaddr> <path_filename> {members
<mslist> | all}
upload sim_ms
[configuration] <ipaddr> <path_filename> <member_id 1-32>
Each command is listed, in detail, in the following sections.
enable sim
Purpose
Used to enable Single IP Management (SIM) on the Switch
Syntax
enable sim
Description
This command will enable SIM globally on the Switch. SIM features
and functions will not function properly unless this function is
enabled.
Parameters None.
