Chapter 1 Overview
Understanding Key Features
SNMP
Both the ONS 15454 SONET/SDH and the ML-Series have Simple Network Management Protocol
(SNMP) agents and support SNMP Version 1 (SNMPv1) and SNMP Version 2c (SNMPv2c) sets and
traps. The ONS 15454 accepts, validates, and forwards get/getNext/set requests to the ML-Series
through a proxy agent. The ML-Series requests contain the slot identification of the ML-Series card to
distinguish the request from a general ONS 15454 SNMP request. Responses from the ML-Series are
relayed by the ONS 15454 to the requesting SNMP agents.
The ML-Series supports SNMP traps, including Spanning Tree Protocol (STP) traps from Bridge-MIB
(management information base) (RFC 1493), the authentication traps from RFC 1157, and the Link-up
and Link-down traps for Ethernet ports from IF-MIB (RFC 1573). For more information on how the ONS
15454 implements SNMP, refer to the “SNMP” chapter of the Cisco ONS 15454 Reference Guide.
Cisco IOS
Cisco IOS controls the data functions of the ML-Series card and comes preloaded on the ONS 15454
TCC+/TCC2 card.
Users cannot update the ML-Series Cisco IOS image in the same manner as the Cisco IOS system image
on a Cisco Catalyst Series. An ML-Series Cisco IOS image upgrade is accomplished only through the
ONS 15454 SONET/SDH CTC, and Cisco IOS images for the ML-Series card are available only as part
of an ONS 15454 software release. This Cisco IOS image is included on the standard ONS 15454
SONET/SDH System Software CD under the package file name M_I.bin and full file name
ons15454m-i7-mz. The images are not available for download or shipped separately.
