13.1 SNMP Overview
The Cisco ONS 15600 SDH supports SNMP Version 1 (SNMPv1), SNMP Version 2c (SNMPv2c), and
SNMP Version 3 (SNMPv3). As compared to SNMPv1, SNMPv2c includes additional protocol
operations and 64-bit performance monitoring support. SNMPv3 provides authentication, encryption,
and message integrity and is more secure. This chapter describes the SNMP versions and describes the
configuration parameters for the ONS 15600 SDH.
It is recommended that the SNMP Manager timeout value be set to 60 seconds. Under certain conditions,
Note
if this value is lower than the recommended time, the TCC card can reset. However, the response time
depends on various parameters such as object being queried, complexity, and number of hops in the
node, etc.
The CERENT-MSDWDM-MIB.mib, CERENT-FC-MIB.mib, and CERENT-GENERIC-PM-MIB.mib
Note
in the CiscoV2 directory support 64-bit performance monitoring counters. The SNMPv1 MIB in the
CiscoV1 directory does not contain 64-bit performance monitoring counters, but supports the lower and
higher word values of the corresponding 64-bit counter. The other MIB files in the CiscoV1 and CiscoV2
directories are identical in content and differ only in format.
Note When you switch multiplex-section shared protection ring (MS-SPRing) traffic from working to protect,
the intermediate path performance monitoring (IPPM) TCAs and SDH near-end path PM values are
available on the protect path. The protect TCA and PM values will not be available after the switch is
cleared. Note that the protection channel access (PCA) TCAs and PM values are collected when the
protect is not active.
