J.8.7 CRS-1 PM Tables Collect Data at the Wrong Collection Interval
sample-interval 15
!
Step 3 If the files are not being dumped to the target directory on the TFTP server, verify that the TFTP server
is using the correct tftpd (tftp daemon binary). The tftpd should be a version that allows the CRS-1 to
create new files in the specified directory. The default tftpd only allows pre-existing TFTP files to be
written. The default tftpd does not create new TFTP files.
Step 4 If the files appear on the TFTP server but do not appear in the PM table, verify that the CTM server is
being notified of PM TFTP file dumping events. To do this, choose Fault > Alarm Log and check for
events that arrive every 15 minutes and resemble the following output:
pm_collector[301]: %PM_COLLECTOR-6-TFTP_SEND : Successfully dumped
file:tftp://<IP_address><TFTP_directory><NE_name>_node_process_1100886887.212000
Step 5 If events do not appear after 15 minutes, verify that configuration change notifications are enabled. See
J.8.3 CTM Does Not Receive Configuration Changed Notifications from the CRS-1, page J-23.
Step 6 If events are present, verify that the TFTP server is reachable from the CTM server. To do this, ping the
IP address that is present in the event notification. If the IP address is not reachable, configure the routes
so that it becomes reachable. Alternately, include a mapping file in the
/opt/CiscoTransportManagerServer/cfg/hfr/IPAddressMapping.cfg directory that includes the following
mapping:
<IP_address_in_event_notification> <reachable_IP_address_of_the_same_TFTP_server>
For example:
172.19.64.51 223.255.254.254
J.8.7 CRS-1 PM Tables Collect Data at the Wrong Collection Interval
You might experience a problem where the PM data collection interval is set to 15 minutes, but the
CRS-1 PM tables are collecting data more frequently (or less frequently).
The CRS-1 collects and dumps data to a binary file on a TFTP server at user-configured intervals based
on the IOS-XR CLI. After dumping the PM data, the CRS-1 notifies CTM with the location of the file.
CTM then collects PM data from the CRS-1. Therefore, you should configure the CRS-1 to collect data
every 15 minutes.
J.8.8 Memory Backup or Restore Fails for the CRS-1
Step 1 Verify that the NE is in service and the communication state is Available.
Step 2 Verify that you can ping the CTM server from the NE. The NE is used as a TFTP client for downloading
the configuration file.
Step 3 In the /etc/inetd.conf file, verify that the TFTP server is enabled on the CTM server. Also, verify that the
specified tftpboot directory has the correct permissions.
