Summary:

This article provides a procedure for copying the entire contents of the /var/log directory into a single file, and then copying it from an EX Switch.

This procedure includes the EX switch virtual chassis (VC) configuration, which requires that the /var/log directory should be copied from each member of the virtual chassis.

 

Solution:

Note: The procedure listed below is for tar'ring and compressing all files in the /var/log directory of an EX switch in a Virtual Chassis (VC). This can be done on any EX switch to copy the entire contents of the /var/log directory from the Routing Engine.

Topology: Three Member Virtual Chassis (VC)

Procedure to tar and copy the /var/log/ directory from each member of a Virtual Chassis (VC):

  1. Log on to the Master EX switch and start shell (if you have logged in as root, you will be logged into shell):

User switch> start shell user root 
  1. root% tar -zcvf varlog-mem0.tar.gz /var/log/
  2. root% ls

Note: You should see the ' varlog-0.tar.gz file generated here.

  1. root% mv varlog-mem0.tar.gz /var/tmp/
  2. root% exit

Note: This will bring you to the CLI '>' prompt of Master switch )

  1. root> request session member 1

Note: This connects you to member 1 of the VC.

  1. root> start shell user root
  2. root% tar -zcvf varlog-mem1.tar.gz /var/log/
  3. root% ls

Note: This will generate varlog-mem1.tar.gz in /root/ directory on backup)

  1. root% mv varlog-mem1.tar.gz /var/tmp/
  2. root% exit
  3. root> file copy fpc1:/var/tmp/varlog-mem1.tar.gz fpc0:/var/tmp/

Note: Copy the member 1 tar file to the member 0 /var/tmp directory.

  1. root> request session member 2
  2. root> start shell user root
  3. root% tar -zcvf varlog-mem2.tar.gz /var/log/
  4. root% ls

Note: This will generate varlog-mem2.tar.gz in /root/ directory

  1. root% mv varlog-mem2.tar.gz /var/tmp/
  2. root% exit
  3. root> file copy fpc2:/var/tmp/varlog-mem2.tar.gz fpc0:/var/tmp/
  4. root> exit

You should be able to see all three log files that were generated and copied into the /var/tmp folder of the master FPC (FPC0).

  • varlog-mem0.tar.gz
  • varlog-mem1.tar.gz
  • varlog-mem2.tar.gz

You can now FTP these files from the EX Switch.
