Figure 9-8 A Multicard EtherSwitch configuration
Caution Whenever you drop two STS-3c multicard EtherSwitch circuits onto an Ethernet card and delete only
the first circuit, you should not provision STS-1 circuits to the card without first deleting the remaining
STS-3c circuit. If you attempt to create a STS-1 circuit after deleting the first STS-3c circuit, the STS-1
circuit will not work and no alarms will indicate this condition. To avoid this condition, delete the second
STS-3c prior to creating the STS-1 circuit.
9.3.2 E Series Single-Card EtherSwitch
Single-card EtherSwitch allows each Ethernet card to remain a single switching entity within the ONS
15454 shelf. This option allows a full STS-12c worth of bandwidth between two Ethernet circuit points.
Figure 9-9 illustrates a single-card EtherSwitch configuration.
Figure 9-9 A Single-card EtherSwitch configuration
Seven scenarios exist for provisioning single-card EtherSwitch bandwidth:
1. STS 12c
2. STS 6c + STS 6c
3. STS 6c + STS 3c + STS 3c
4. STS 6c + 6 STS-1s
