Release 7.0.0 3DB 19286 ACAA Issue 01
Administer VLAN configuration
In 802.1Q mode all Ethernet frames inside the 9500 MPR network are assigned a
VLAN ID.
VLAN 1 is automatically defined by the NE when 802.1Q is selected. All user
Ethernet ports (enabled and disabled) and all radio ports are members of VLAN 1.
VLAN 1 can't be modified or deleted by the operator. In egress VLAN ID 1 is always
removed from the ports.
VLAN IDs 2-4080 are configurable. VLAN IDs associated with TDM2TDM or
TDM2ETH cross-connections can not be used for 802.1Q VLAN IDs. VLAN IDs
associated with future E1/DS1/DS3 tributary cross-connections should not be used
for 802.1Q VLAN IDs.
The management system prohibits the definition of VLAN IDs already provisioned.
User Ethernet ports provisioned as 'Untagged Ports', remove the VLAN ID from the
Ethernet frame on egress. Only User Ethernet ports are manageable. VLAN IDs
cannot be removed from radio ports.
The management system denies an attempt to disable any radio port that is a
member of a static VLAN. To disable the radio port, the user must first remove the
radio port as a member of a static VLAN.
If a VLAN rate limiter is set on a port, the VLAN cannot be modified. The rate limiting
must be removed before making any change to the VLAN.
23.2.3 802.1ad (Provider Bridge)
When the NE is configured in Provider Bridge mode, the forwarding of Ethernet traffic
is managed according to Service VLAN. Each Service VLAN (S-VLAN) represents a
service instance that Ethernet traffic from a customer network is mapped to.
In Provider Bridge mode, an S-VLAN is assigned to all Ethernet frames managed by
the NE. The assignment of an S-VLAN to an Ethernet frame ingressing the NE shall
be done according to the type of the Provider Bridge port:
186
• NNI: this is an interface internal to the Provider Bridged Network. S-VLAN is
assigned based on S-VLAN ID carried by S-VLAN Tag or based on the ingress
interface in case of S-VLAN untagged frames
• UNI (port based): this is an interface at the edge of the Provider Bridged
Network. S-VLAN is assigned based on User Ethernet port (Port-based service
interface) regardless of the type of customer traffic (C-VLAN tagged or
untagged)
