Chapter 16 CE-100T-8 Ethernet Operation
CE-100T-8 SONET Circuits and Features
Statistics and Counters
The CE-100T-8 has a full range of Ethernet and POS statistics under Performance > Ether Ports or
Performance > POS Ports. These are detailed in the “Performance Monitoring” chapter of the Cisco
ONS 15310 Reference Manual.
CE-100T-8 SONET Circuits and Features
The CE-100T-8 has eight POS ports, numbered one through eight, which are exposed to management
with CTC or TL1. Each POS port is statically mapped to a matching Ethernet port. By clicking the
card-level Provisioning tab > POS Ports tab, the user can configure the Administrative State, Framing
Type, and Encapsulation Type. By clicking the card-level Performance tab > POS Ports tab, the user can
view the statistics, utilization, and history for the POS ports.
Available Circuit Sizes and Combinations
Each POS port terminates an independent contiguous SONET concatenation (CCAT) or virtual SONET
concatenation (VCAT). The SONET circuit is created for these ports through CTC or TL1 in the same
manner as a SONET circuit for a non-Ethernet line card. Table 16-3 shows the circuit sizes available for
the CE-100T-8 on the ONS 15310-CL.
A single circuit provides a maximum of 100 Mbps of throughput, even when an STS-3c circuit, which
has a bandwidth equivalent of 155 Mbps, is provisioned. This is due to the hardware restriction of the
Fast Ethernet port. A VCAT circuit is also restricted in this manner. Table 16-3 shows the minimum
SONET circuit sizes required for 10 Mbps and 100 Mbps wire speed service.
*STS-1-2v provides a total transport capacity of 98 Mbps.
The number of available circuits and total combined bandwidth for the CE-100T-8 depends on the
combination of circuit sizes configured. Table 16-5 shows the circuit size combinations available for
CE-100T-8 CCAT high-order circuits on the ONS 15310-CL. Table 16-6 shows the circuit size
combinations available for CE-100T-8 VCAT high-order circuits on the ONS 15310-CL.
