2. Specify where the system should transfer the core dump file.
3. Set the IP address and mask of the system interface over which you want to send the core dump file.
4. Specify the gateway through which the system sends the core dump file to the FTP server.
5. (Optional) Set a username and password for FTP access to the server where you want to transfer the core dump file.
6. (Optional) View parameters associated with creating a core dump file.

   Example

   host1(config)#exception dump 192.168.56.7 CORE_DUMPS

   host1(config)#exception protocol ftp username userpassword

   host1(config)#exception gateway 192.168.12.3

   host1(config)#reload

exception dump

• Use to specify where the system should transfer the core dump file.
  • To send the file to an FTP server, enter the IP address of the FTP server and the name of the directory on the server to which the system will transfer the file.
  • To send the core dump file to NVS memory, use the local keyword.
  • Local core dumps—stored in NVS—are enabled by default.
• Example

  host1(config)#exception dump 192.168.56.7 CORE_DUMPS

• Use the no version to disable the core dump.
• See exception dump.

exception gateway

• Use to specify the gateway through which the system sends the core dump file to the FTP server.
• Example

  host1(config)#exception gateway 10.10.1.15

• Use the no version to return the value to its default (null).
• See exception gateway.

exception protocol ftp

• Use to set a username and password for FTP access to the server where you transferred a core dump file. The default settings are the username anonymous and no password.
• Specify the number 8 before the username and before the password to encrypt these values. By default, the username and password are not encrypted.
• Example

  host1(config)#exception protocol ftp 8 user_core 8 user_password

• Use the no version to restore the default settings.
• See exception protocol ftp.

exception source

• Use to set the IP address and mask of the system interface over which you want to send the core dump file to the FTP server.
• You can optionally include an IP address mask.
• Example

  host1(config)#exception source 192.168.1.33 255.255.255.0

• Use the no version to return the value to its default, null.
• See exception source.

reload

• Use to reload the software on the router immediately.
• Reloads the system software (.rel) file and the configuration (.cnf) file.
• Reloading the standby SRP causes high availability to be temporarily disabled until the standby SRP reloads and resynchronizes with the active SRP.
• Example

  host1#reload

• There is no no version.
• See reload.
