Default

The default settings for SSH2 parameters are as follows:
  • cipher—the full cipher list
  • mac—the full Message Authentication Code list
  • port—22
  • compression—off
  • vr_name—VR-Mgmt

Usage Guidelines

SSH2 does not need to be enabled on the switch in order to use this command.

This command logs into the remote host as user and accesses the file remote_file. You will be prompted for a password from the remote host, if required.

The following command copies the configuration file engineering.cfg from the switch to host system1: 

# scp2 engineering.cfg admin@system1:engineering.cfg

The following command copies the file Anna5.xsf from the default virtual router to 150.132.82.140: 

# scp2 vr vr-default Anna5.xsf root@150.132.82.140:Anna5.xsf
Upload /config/Anna5.xsf to
Connecting to 150.132.82.140...
