Using SNMP to Manage the Switch
SNMP Commands An administrator at a management station requests information from
an agent by sending a variation of a single command:
◆
get — Retrieves the value of variables at the agent.
◆
set — Sets the value of variables at the agent.
Each group and variable in a MIB is assigned a numerical address.
You can enter commands with variables specified as a name or a
number. For example:
get {root, iso, org, dod, internet, mgmt, mib-2, system}
or
get {root, 1, 3, 6, 1, 2, 1, 1}
Traps
Traps are unsolicited status reports, or status change indicators a
managed object sends to a network manager. The destination address
for traps is a configuration item for each managed agent.
The Connectrix SNMP implemenation supports standard generic
traps and enterprise-specific traps.
Unsolicited SNMP trap messages are transmitted to authorized
management workstations:
◆
When SNMP notifications are configured in the switch Product
Manager, unsolicited SNMP trap messages can be transmitted to
up to six authorized management workstations.
◆
When SNMP notifications are configured in the Connectrix
Manager, unsolicited trap messages can be transmitted to up to 12
authorized management workstations.
Unsolicited SNMP trap messages signal operational state changes
and failure conditions. Generic SNMP traps include:
◆
coldStart — Reports that the SNMP agent is reinitializing due to a
power-on reset.
◆
warmStart — Reports that the agent is reinitializing due to an
Initial Machine Load (IML) or Initial Program Load (IPL).
◆
authorizationFailure — Reports access by an unauthorized
SNMP manager.
