SNMP on the ML-Series Card
SNMP operates in two different ways on the ONS 15454 SONET/SDH ML-Series card. One way is to
communicate directly. This is also how SNMP operates on a small Catalyst switch, using direct
communication, Cisco IOS, and the data plane. An SNMP agent interacting with an ML-Series card can
also communicate through the ONS 15454 SONET/SDH and the SONET network. Both ways are shown
in Figure
Figure 22-1
When the ONS 15454 SONET/SDH node relays the ML-Series card SNMP communication, the node
uses a proxy agent to accept, validate, and forward get, getNext, and set requests to the ML-Series card.
These ML-Series card requests contain the slot identification of the ML-Series card cards to distinguish
the request from a general SNMP request for the ONS 15454 SONET/SDH node. The responses from
the ML-Series card are then relayed by the ONS 15454 SONET/SDH node to the requesting SNMP
agents.
SNMP access is useful for collecting Cisco IOS data plane events, alarms, and statistics for the
ML-Series card. All SNMP events and traps defined on the ML-Series card are reported to the
TCC2/TCC2P card SNMP agent by default. If the TCC2/TCC2P card SNMP agent is active, these events
are sent to the defined SNMP server.
