Removing VLANs from a switch
To remove existing VLANs from the switch, complete the following steps:
1 Select the Secure Access Domain > domain > Switches > switch > VLANs
tab.
The switch VLANs screen appears (see Figure 10).
2 Select a VLAN entry from the VLAN Table.
3 Click Delete.
A dialog box appears to confirm that you want to delete this VLAN.
4 Click Yes.
The VLAN disappears from the VLAN Table.
5 Click Apply on the toolbar to send the current changes to the Nortel
SNAS 4050. Click Commit on the toolbar to save the changes permanently.
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.
To enable secure communication between the Nortel SNAS 4050 and the network
access device, do the following:
1 Generate 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.
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.
