13.2 Basic SNMP Components

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.
When you switch BLSR traffic from working to protect, the intermediate path performance monitoring
Note
(IPPM) TCAs and SONET 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.

In general terms, an SNMP-managed network consists of a management system, agents, and managed
devices.
