Nortel Secure Network Access Switch 4050 User Guide
Use the applicable show commands on the router to verify that DHCP
relay has been activated to reach the correct scope for each VLAN.
For more information about performing these general configuration steps, see
the regular documentation for the type of router used in your network.
4 Configure the network access devices:
a Configure static routes to all the networks behind the core router.
b Configure the switch management VLAN, if necessary.
c Configure and enable SSH on the switch.
d Configure the Nortel SNAS 4050 portal Virtual IP address (pVIP)/subnet.
e Configure port tagging, if applicable.
For a Layer 2 switch, the uplink ports must be tagged to allow them to
participate in multiple VLANs.
f Create the port-based VLANs.
These VLANs are configured as VoIP, Red, Yellow, and Green VLANs
in step i and step j.
g Configure DHCP relay and IP routing if the switch is used in Layer 3
mode.
h (Optional) Configure the Red, Yellow, Green, and VoIP filters.
The filters are configured automatically as predefined defaults when you
configure the Red, Yellow, and Green VLANs (step j). Configure the
filters manually only if your particular system setup requires you to
modify the default filters. You can modify the filters after NSNA is
enabled.
i Configure the VoIP VLANs.
j Configure the Red, Yellow, and Green VLANs, associating each with the
applicable filters.
k Configure the NSNA ports.
