The switch VLANs screen appears (see Figure 10).

2Select a VLAN entry from the VLAN Table.

3Click Delete.

A dialog box appears to confirm that you want to delete this VLAN.

4Click Yes.

The VLAN disappears from the VLAN Table.

5Click Apply on the toolbar to send the current changes to the Nortel

Managing SSH keys using the SREM

The Nortel SNAS 4050 and the network access devices controlled by the Nortel SNAS 4050 domain exchange public keys so that they can authenticate themselves to each other in future SSH communications.

Note: When you add a new network access device, the SSH fingerprint of the switch is automatically picked up if the switch is reachable. If the fingerprint is not successfully retrieved, then the SSH key will not be set for this network access device.

To enable secure communication between the Nortel SNAS 4050 and the network access device, do the following:

1Generate an SSH public key for the Nortel SNAS 4050 domain (see “Generating SSH keys for the domain using the SREM” on page 105), if necessary. Apply the change immediately.
