Special case VLAN numbers
This system handles special case VLAN numbers according to IEEE specifications:
Table 54 Special case VLAN IDs
VLAN
Number
Purpose Usage Constraint
0
These packets have 802.1p priority, but are otherwise
handled as untagged.
Should not be used as a
management VLAN.
1
Although not noted as special case by IEEE specifications,
these packets identify traffic that was untagged upon
ingress into the SM and should remain untagged upon
egress. This policy is hard-coded in the AP.
Should not be used for system
VLAN traffic.
4095 This VLAN is reserved for internal use. Should not be used at all.
SM membership in VLANs
With the supported VLAN functionality, the radios determine bridge forwarding on the basis of not only the
destination MAC address, but also the VLAN ID of the destination. This provides flexibility in how SMs are
used:
• Each SM can be a member in its own VLAN.
• Each SM can be in its own broadcast domain, such that only the radios that are members of the VLAN can
see broadcast and multicast traffic to and from the SM.
• The network operator can define a work group of SMs, regardless of the AP(s) to which they register.
