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 16-3shows the circuit sizes available for the CE-100T-8 on the ONS 15310-CL.
Table 16-3 CE-100T-8 Supported Circuit Sizes
CCAT High Order | VCAT High Order | VCAT Low Order |
| | |
STS-1 | STS-1-1v | VT1.5-nV (n= 1 to 64) |
| | |
STS-3c | STS-1-2v | |
| | |
| STS-1-3v | |
| | |
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 16-3shows the minimum SONET circuit sizes required for 10 Mbps and 100 Mbps wire speed service.
Table 16-4 SONET Circuit Size Required for Ethernet Wire Speeds
Ethernet Wire Speed | CCAT High Order | VCAT High Order | VCAT Low Order |
| | | |
Line Rate 100BaseT | STS-3c | STS-1-3v, STS-1-2v* | Not applicable |
| | | |
Sub Rate 100BaseT | STS-1 | STS-1-1v | VT1.5-xV (x=1-64) |
| | | |
Line Rate 10BaseT | STS-1 | Not applicable | VT1.5-7V |
| | | |
Sub Rate 10BaseT | Not applicable | Not applicable | VT1.5-xV (x=1-6) |
| | | |
*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 16-5shows the circuit size combinations available for CE-100T-8 CCAT high-order circuits on the ONS 15310-CL. Table 16-6shows the circuit size combinations available for CE-100T-8 VCAT high-order circuits on the ONS 15310-CL.
