Nortel Secure Network Access Switch 4050 User Guide
If you regenerate the key at any time, you must re-export the key to each
network access device.
3
For each network access device, import its public key into the Nortel
SNAS 4050 domain, if necessary (see
“Managing SSH keys for Nortel SNA
communication using the CLI” on page 88 ).
• For an Ethernet Routing Switch 8300, you can retrieve the key in two
ways:
— Use the
/cfg/domain #/switch #/sshkey/import
command
to import the key directly from the network access device.
— Use the
/cfg/domain #/switch #/sshkey/add
command to
paste in the key.
• For an Ethernet Routing Switch 5510, 5520, or 5530:
— Use the
/cfg/domain #/switch #/sshkey/import
command
to import the key directly from the network access device.
If the network access device was reachable when you added it to the domain
configuration, the SSH key was automatically retrieved.
If the network access device defaults, it generates a new public key. You must
reimport the key whenever the switch generates a new public key (see
“Reimporting the network access device SSH key using the CLI” on page 89 ).
Generating SSH keys for the domain using the CLI
To generate, view, and export the public SSH key for the domain, use the
following command:
/cfg/domain #/sshkey
The NSNAS SSH key menu displays.
Note: If you export the key after the network access device has been
enabled, you may need to disable and re-enable the switch in order to
activate the change.
Note: In general, enter
Apply
to apply the changes immediately after
you execute any of the SSH commands.
