Chapter 23 E-Series and G-Series Ethernet Operation
To enable flow control between an E-Series in port-mapped mode and a SmartBits test set, manually set
Note
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.
A high number of VLANs (over 100) may cause traffic outage.
Caution
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.
Port-mapped mode does not support VLANs.
Note
The number of VLANs used by circuits and the total number of VLANs available for use appears in CTC
on the VLAN counter
