DT-6061 User's Manual - Platform (Build 16.0)

! The absence of one or more DT-4000's from the network when they occur in the dtproduct
list on a DT-6061 can cause up to a 10-second (total) delay when rebooting that DT-6061.
! There is very little overhead in adding 'D' to a dtproduct configuration of a DT-6061, as long
as the DT-4000 associated with 'D' is usually up and running when this DT-6061 is rebooted;
otherwise the 10 second boot delay described above may apply. However, a list larger than
40 or 50 should be carefully managed.
6.20 CONFIGURE SNMP
Syntax: snmp get=<communities> set=<communities>
trap=<community> dest=<IP address> cug=[+|]<cuglist>
(prompted: sysName=<esc> sysLoc=<esc> sysContact=<esc>)
The snmp command is only allowed when the unit is logged in.
The snmp command configures or verifies the parameters needed to permit the SNMP agent to
communicate with a manager using closed user groups and user-specified communities for gets
and sets. The DT-6061 will not respond to other community names. The <communities>
parameter accepts a comma-separated list of community names. The communities configured for
set also work for get, so they need not be repeated in the get parameter. The closed user group
option (cug) defines which IP addresses are allowed to do gets and sets. Values are saved in
non-volatile memory. There is only one trap=<community>. The dest=<IP address> parameter
configures the IP address of the target trap manager. The snmp vfy command (same as vfy
snmp) displays the current settings of SNMP configuration.
The snmp command prompts for all parameters not specified on the command line. Simply type
snmp in order to add or change any parameters. If the present value that is printed is to be
retained, hit newline in response to the prompt. In order to add to an existing list for the set and
get communities, type in the old values as well as the additions for that parameter when
prompted. To delete all values for a keyword, type the word “none” as the value. Special
characters and escape sequences are accepted for community strings, sysName, sysLoc, and
sysContact parameters, but must be entered at the prompt for that parameter, not on the
command line.
When the SNMP configuration is changed, the agent is restarted. Whenever the DT-6061 reboots
or the agent is restarted, a warm-start trap is sent to the configured trap manager. The only other
trap sent by the DT-6061 platform agent is "authentication fail" when a manager attempts to use a
community name not on the list. This trap is only sent if a manager has enabled it to be sent.
The snmp sysName, sysLoc, and sysContact are changeable via an SNMP manager as well as
via the console.
The enterprise object ID of the DT-6061 platform is 1.3.6.1.4.1.3791.3.7.
6.21 CLOSED USER GROUPS
Syntax: cug <cugnum>[ipaddr=<d.d.d.d>][submask=<IP submask>]
The cug command is only allowed when the unit is logged in.
The <cugnum> parameter is the closed user group identifier used to assign the CUG to the
SNMP interface (with the SNMP command). If SNMP is configured with one or more CUGs, only
callers belonging to those CUGs are allowed to issue GETs and SETs. If no CUG is assigned to
SNMP, any caller is allowed to do SETs and GETs. (SNMP also requires adherence to the
community strings configured for SET and GET.)
Each CUG is specified by a single IP address and subnet-mask pair. The ipaddr parameter is an
IP address or the base address of an IP subnetwork that identifies members of the group. The
