NET SNMP Client

To manage the device using the simple network management protocol (SNMP) through scripts, the Dell

Networking OS supports the NetSNMP client.

You can run scripts that use SNMP to manage the data center and devices from within the Dell

Networking OS. The Dell Networking OS provides Perl, Python, and Ruby interfaces for the NetSNMP

client. To execute the SNMP operations, use the tclsh exec command. As a part of the NetSNMP

client, the following utility applications are supported:

•

snmpwalk

• snmpget

• snmpset

• snmpbulkget

• snmpbulkwalk

• snmpbulknext

Limits on System Usage

To restrict CPU and memory usage, Smart Scripting establishes limits on system processes for the

following attributes (regardless of the user-privilege level or scripting method).

Table 2. Limits on System Attributes

System Attributes Value Description

cputime

unlimited Maximum amount of time a

process uses.

filesize

unlimited Largest file size (in bytes) that can

be created.

datasize

131,072 Maximum size (in bytes) of the

data segment for a process; this

value defines how far a program

may extend its break with the

sbrk(2) system call.

stacksize

2,408 Maximum size (in bytes) of the

stack segment for a process; this

value defines how far a program’s

stack segment can be extended.

The system automatically

performs stack extension.

coredumpsize

unlimited Largest size (in bytes) of a core

file that can be created.

memory use

233,244 Maximum size (in bytes) to which

a process’s resident set size may

grow. This value imposes a limit

on the amount of physical
