E-Series VLAN Support
Note To enable flow control between an E-Series in port-mapped mode and a SmartBits test set, manually set
Bit 5 of the MII register to 0 on the SmartBits test set. To enable flow control between an E-Series in
port-mapped mode and an Ixia test set, select Enable the Flow Control in the Properties menu of the
attached Ixia port.
E-Series VLAN Support
You can provision E-Series VLANs with the CTC software. Specific sets of ports define the broadcast
domain for the ONS node. The definition of VLAN ports includes all Ethernet and packet-switched
SONET/SDH port types. All VLAN IP address discovery, flooding, and forwarding is limited to these
ports.
Caution A high number of VLANs (over 100) may cause traffic outage.
The IEEE 802.1Q-based VLAN mechanism provides logical isolation of subscriber LAN traffic over a
common SONET/SDH transport infrastructure. Each subscriber has an Ethernet port at each site, and
each subscriber is assigned to a VLAN. Although the subscriber’s VLAN data flows over shared circuits,
the service appears to the subscriber as a private data transport.
Note Port-mapped mode does not support VLANs.
The number of VLANs used by circuits and the total number of VLANs available for use appears in CTC
on the VLAN counter (Figure 23-14).
