configured lines. This feature is enabled and disabled through use of the CLI and MIBs. DS0
busyout traps are disabled by default and are supported on Cisco AS5300, Cisco AS5400, and
Cisco AS5800 universal access servers.
• Enabling ISDN PRI Requested Channel Not Available Traps—ISDN PRI channel not available traps
are generated when a requested DS0 channel is not available, or when there is no modem available
to take the incoming call. This feature is available only for ISDN PRI interfaces. This feature is
enabled and disabled through use of CLI for ISDN traps and the CISCO-ISDN-MIB. ISDN PRI
channel not available traps are disabled by default and are supported on the Cisco AS5300,
Cisco AS5400, and Cisco AS5800.
• Enabling Modem Health Traps—Modem health traps are generated when a modem port is bad,
disabled, reflashed, or shut down, or when there is a request to busy out the modem. This feature is
enabled and disabled through use of CLI and the CISCO-MODEM-MGMT-MIB. Modem health
traps are disabled by default and are supported on the Cisco AS5300, Cisco AS5400, and
Cisco AS5800.
• Enabling DS1 Loopback Traps—DS1 loopback traps are generated when a DS1 line goes into
loopback mode. This feature is enabled and disabled by CLI and the CISCO-POP-MGMT-MIB. DS1
loopback traps are disabled by default and are supported on the Cisco AS5300 and Cisco AS5400
only.
The CISCO-POP-MGMT-MIB supplies the DS0 busyout traps and the DS1 loopback traps. The
CISCO-MODEM-MGMT-MIB supplies additional modem health traps when the modem port becomes
non-functional. The CISCO-ISDN-MIB supplies additional traps for ISDN PRI channel not available.
To obtain lists of supported MIBs by platform and Cisco IOS release, and to download MIB modules,
go to the Cisco MIB website on Cisco.com at
http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml.
See the sections “Verifying Enabled Traps” and “Troubleshooting the Traps” to verify and troubleshoot
configuration. The section “NAS Health Monitoring Example” provides output of a configuration with
the NAS health monitoring features enabled.
Enabling DS0 Busyout Traps
Before you enable DS0 busyout traps, the SNMP manager must already have been installed on your
workstation, and the SNMP agent must be configured on the NAS by entering the snmp-server
community and snmp-server host commands. Refer to the Cisco IOS Configuration Fundamentals
Configuration Guide for more information on these commands.
To generate DS0 busyout traps, use the following command in global configuration mode:
Command Purpose
Router(config)# snmp-server enable traps
ds0-busyout
Generates a trap when there is a request to busy out a DS0 or to
indicate when busyout finishes.
