Chapter 23 E-Series and G-Series Ethernet Operation
In normal SONET/SDH mode, the G-Series cards supports an end-to-end link integrity function. This
Note
function causes an Ethernet or SONET/SDH failure to disable and turn the transmitting laser off in the
corresponding mapped Ethernet port. In transponder mode, the loss of signal on an Ethernet port has no
impact on the transmit signal of the corresponding mapped port.
The operation of a G-Series card in transponder mode is also similar to the operation of a G-Series card
in SONET/SDH mode:

E-Series Application

The ONS 15454 and ONS 15454 SDH support E-Series cards. E-Series cards include the
E100T-12/E100T-G and the E1000-2/E1000-2-G on the ONS 15454 and ONS 15454 SDH. The E100T-G
is the functional equivalent of the earlier E100T-12. The E1000-2-G is the functional equivalent of the
earlier E1000-2. An ONS 15454 using XC10G cards requires the G versions (E100T-G or E1000-2-G)
of the E-Series Ethernet cards. An ONS 15454 or ONS 15454 SDH supports a maximum of ten E-Series
cards. You can insert E-Series Ethernet cards in any multipurpose slot.
The ONS 15454 and ONS 15454 SDH E-Series cards do not support LEX encapsulation.
Note

E-Series Modes

An E-Series card operates in one of three modes: multicard EtherSwitch group, single-card EtherSwitch,
or port-mapped. E-Series cards in multicard EtherSwitch group or single-card EtherSwitch mode
support Layer 2 features, including virtual local area networks (VLANs), IEEE 802.1Q, STP, and
IEEE 802.1D. Port-mapped mode configures the E-Series to operate as a straight mapper card and does
not support these Layer 2 features. Within a node containing multiple E-Series cards, each E-Series card
can operate in any of the three separate modes. At the Ethernet card view in CTC, click the
Provisioning > Ether Card tabs to reveal the card modes.
Note Port-mapped mode eliminates issues inherent in other E-Series modes and is detailed in the field notice,
"E-Series Ethernet Line Card Packet Forwarding Limitations."
G-Series Ethernet statistics are available for ports in both modes.
Ethernet port level alarms and conditions are available for ports in both modes.
Jumbo frame and non-Jumbo frame operation is the same in both modes.
Collection, reporting, and threshold crossing conditions for all existing counters and PM parameters
are the same in both modes.
Simple Network Management Protocol (SNMP) and RMON support is the same in both modes.
