Using SNMP

SNMP Overview

OmniSwitch 6600 Family Switch Management Guide

page 10-9

The following table provides information on all SNMP traps supported by the switch. Each row includes 
the trap name, its ID number, any objects (if applicable), its command family, and a description of the 
condition the SNMP agent in the switch is reporting to the SNMP management station. You can generate a 
list of SNMP traps that are supported on your switch by using the

coldStart

chassis

The SNMP agent in the switch is 

reinitiating and its configuration 
may have been altered.

chassis

The SNMP agent in the switch is 

reinitiating itself and its configu-
ration is unaltered.

IfIndex

interface

The SNMP agent in the switch 

recognizes a failure in one of the 
communications links configured 

for the switch.

IfIndex—A unique value, greater than zero, for each interface. It is recommended that values are assigned con-
tiguously starting from 1. The value for each interface sub-layer must remain constant at least from one re-ini-

tialization of the entity’s network management system to the next re-initialization.

ifAdminStatus—The desired state of the interface. The testing(3) state indicates that no operational packets 
can be passed. When a managed system initializes, all interfaces start with ifAdminStatus in the down(2) state. 

As a result of either explicit management action or per configuration information retained by the managed sys-

tem, ifAdminStatus is then changed to either the up(1) or testing(3) states (or remains in the down(2) state).
ifOperStatus—The current operational state of the interface. The testing(3) state indicates that no operational 

packets can be passed. If ifAdminStatus is down(2) then ifOperStatus should be down(2). If ifAdminStatus is 

changed to up(1) then ifOperStatus should change to up(1) if the interface is ready to transmit and receive net-
work traffic; it should change to dormant(5) if the interface is waiting for external actions (such as a serial line 

waiting for an incoming connection); it should remain in the down(2) state if and only if there is a fault that pre-

vents it from going to the up(1) state; it should remain in the notPresent(6) state if the interface has missing 
(typically, hardware) components.

The SNMP agent in the switch 

recognizes that one of the com-
munications links configured for 

the switch has come up.

tiguously starting from 1. The value for each interface sub-layer must remain constant at least from one re-ini-

ifOperStatus—The current operational state of the interface. The testing(3) state indicates that no operational 

packets can be passed. If ifAdminStatus is down(2) then ifOperStatus should be down(2). If ifAdminStatus is

The SNMP agent in the switch 
has received a protocol message 

that is not properly authenticated.
