Chapter 23 E-Series and G-Series Ethernet Operation
E-Series Application
Note In normal SONET/SDH mode, the G-Series cards supports an end-to-end link integrity function. This
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 signa l on an Ethernet port has no
impact on the transmit signal of the corresponding mapp ed port.
The operation of a G-Series card in transponder mode is als o similar to the operation of a G-Series card
in SONET/SDH mode:
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.
E-Series Application
The ONS 15454, ONS 15454 SDH and ONS 15327 all support E-Se ries 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 15327 E-Series card is the E10/100-4. This is the only E-Series card that supports LEX
encapsulation configuration, which allows interoperability with ML-Series cards, for more information
see Chapter 20, “POS on ONS Ethernet Cards.”
Note The ONS 15454 and ONS 15454 SDH E-Series cards do not support LEX encapsulation.

E-Series Modes

An E-Series card operates in one of three modes: multicard EtherSwitch gr oup, 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 car d 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 a nd is detailed in the field notice,
“E-Series Ethernet Line Card Packet Forwarding Limitations.”
