If you created the domain manually, the SSH key was generated automatically
(see “Manually creating a domain using the SREM” on page 152).
2 Export the Nortel SNAS 4050 public key to each network access device.
• For an Ethernet Routing Switch 8300, you can export the key directly to
the switch (see “Managing SSH keys for Nortel SNA communication
using the SREM” on page 109).
• For an Ethernet Routing Switch 5510, 5520, or 5530, upload the key to a
TFTP server, for manual retrieval from the switch (see “Exporting SSH
keys for the domain using the SREM” on page 106). For information
about downloading the key from the server to the switch, see Release
Notes for Nortel Ethernet Routing Switch 5500 Series, Software Release
4.3 (217468-B).
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. You can retrieve the key in two ways (see
“Managing SSH keys for Nortel SNA communication using the SREM” on
page 109):
•Use Import SSH Key from Switch to import the key directly from the
network access device.
• (For the Ethernet Routing Switch 8300 only) Paste the SSH key value
into the available text area, and Add the new SSH key manually.
If the network access device was reachable when you added it to the domain
configuration, the SSH key was automatically retrieved.
Note: The SSH key for the Nortel SNAS 4050 domain is not the same
as the SSH key generated during initial setup for all Nortel SNAS 4050
hosts in the cluster (see “Initial setup”, step 15 on page 57).
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.
