Mapping the VLANs using the SREM
The VLANs are configured on the network access devices. You specify the Red
VLAN for each network access device when you add the switch (see
VLAN for each network access device when you add the switch (see
). After adding the switch,
you must identify the Yellow and Green VLANs to the Nortel SNAS 4050.
You can perform the VLAN mapping in two ways:
•
for all switches in a domain (see
)
•
switch by switch (see
)
Nortel recommends mapping the VLANs by domain. In this way, if you later add
switches which use the same VLAN IDs, their VLAN mappings will
automatically be picked up.

If you map the VLANs by domain, you can modify the mapping for a particular
network access device at the switch level. Switch-level settings override domain
settings.

settings.
The Nortel SNAS 4050 maintains separate maps for the domain and the switch. If
you add a domain-level VLAN, then you must use the domain-level command for
all future management of that mapping. Similarly, if you add a switch-level
VLAN, then you must use the switch-level command for all future management
of that mapping.
