Network Services Setup
This chapter covers information related to network services setup using the
switch’s web interface, including how to configure these protocols:
• Simple Network Management Protocol (SNMP)
• Internet Group Management Protocol (IGMP)
• Dynamic Host Configuration Protocol (DHCP)
For information about how to access the web interface for the switch, refer to
Chapter 1 .
SNMP Simple Network Management Protocol (SNMP) specifies the diagnostic data
that a host computer must maintain for network management software. Hosts
typically keep statistics on the status of their network interfaces, incoming and
outgoing traffic, dropped datagrams, and error messages generated. Network
management protocols let network management software access these statistics.
SNMP is based on three concepts:
• SNMP managers, also known as client software or SNMP browsers
• SNMP agents, also known as network devices or SNMP servers
• Management Information Base (MIB)
The SNMP manager runs SNMP management software. Network devices to be
managed, such as bridges, routers, servers, and workstations, have an agent
software module. The agent provides access to a local MIB of objects that reflects
the resources and activity of the device. The agent also responds to manager
commands to retrieve values from the MIB. The agent and the MIB are on the
switch. To configure SNMP on the switch, you define the relationship between
the manager and the agent.
The Stratix 6000 switch supports SNMP versions 1 and 2.
• SNMP versions 1 and 2 are generally used for network monitoring
without network control.
• The supported versions use a community-based form of security. SNMP
managers can access the agent MIB through passwords referred to as
community names.
• The Stratix 6000 switch automatically recognizes the SNMP version from
an incoming request, but you must manually set the version for SNMP
trap destinations, as described on
page 24 .
