Chapter 9 Monitoring Your Network Topology
Monitoring Without the OSC or In-Band Message Channel
For information about other commands that enable SNMP trap notifications, refer to the
Cisco IOS Configuration Fundamentals Command Reference publication.
Example
The following example shows how to enable SNMP trap notifications for processor redundancy activity.
Switch# configure terminal
Switch(config)# snmp-server enable traps rf
Monitoring Without the OSC or In-Band Message Channel
To take advantage of the OSC, the Cisco ONS 15530 system must be equipped with oneOADM module
with OSC (for unprotected configurations) or two OADM modules with OSC (for protected
configurations). Likewise, to take advantage of the in-band message channel, the system must be equiped
with a 10-Gbps ITU trunk card or a 10-GE uplink card. If your system is not equipped to support the
OSC or in-band message channel, the following conditions apply:
• You cannot reach other nodes on the network using Telnet or SNMP. Separate connections to each
system must exist on the network for management purposes.
• CDP does not function on the network. The physical topology must be configured manually for fault
isolation and system management.
• Keepalive information is not available for other nodes on the network.
Setting up Connections to Individual Nodes
To access individual nodes in a Cisco ONS 15530 network without the OSC, you must establish separate
connections to a management port on each system. This can be done using a Telnet session over an
Ethernet connection, a console connection, or a modem connection to the auxiliary port. For instructions
on how to do this, see Chapter 3, “Initial Configuration.”
For NMS without the OSC, each node reports individually to the NMS. Thus you must connect the NMS
to each node using SNMP over an Ethernet connection.
