E-Series IEEE 802.3z Flow Control
Port-mapped mode also allows the creation of STS/VC circuits between any two E-Series cards,
including the E100T-G, E1000-2-G, and the E10/100-4 (the ONS 15327 E-Series card). Port-mapped
mode does not allow ONS 15454 E-Series cards to connect to the ML-Series or G-Series cards, but does
allow an ONS 15327 E10/100-4 card provisioned with LEX encapsulation to connect to the ML-Series
or G-Series cards.
Available Circuit Sizes For E-Series Modes
Table 23-1 shows the circuit sizes available for E-Series modes on the ONS 15454, ONS 15454 SDH,
and ONS 15327.
Available Total Bandwidth For E-Series Modes
Table 23-1 shows the total bandwidth available for E-Series modes on the ONS 15454, ONS 15454 SDH,
and ONS 15327.
E-Series IEEE 802.3z Flow Control
The E100T-G or E10/100-4 (operating in any mode) and the E1000-2-G (operating port-mapped mode)
support IEEE 802.3z symmetrical flow control and propose symmetric flow control when
autonegotiating with attached Ethernet devices. For flow control to operate, both the E-Series port and
the attached Ethernet device must be set to autonegotiation (AUTO) mode. The attached Ethernet device
might also need to have flow control enabled. The flow-control mechanism allows the E-Series to
respond to pause frames sent from external devices and send pause frames to external devices.
