Caveats
E1000-2/E100T
Do not use the repair circuit option with provisioned stitched Ethernet circuits.This issue is under
investigation.
Single-card EtherSwitch
Starting with Release 2.2.0, each E100/E1000 card can be configured as a single-card EtherSwitch
configuration to allow STS-12c of bandwidth to be dropped at each card. The following scenarios for
provisioning are available:
1. 12c
2. 6c, 6c
3. 6c, 3c, 3c
4. 6c, six STS-1s
5. 3c, 3c, 3c, 3c
6. 3c, 3c, six STS-1s
7. Twelve STS-1s
When configuring scenario 3, the STS-6c must be provisioned before either of the STS-3c circuits.
Multicard EtherSwitch
When deleting and recreating Ethernet circuits that have different sizes, you must delete all STS circuits
provisioned to the EtherSwitch before you create the new circuit scenario. (See the preceding
“Single-card EtherSwitch” section for details on the proper order of circuit creation.) Enable front ports
so that the VLANs for the ports are carried by the largest circuit first. A safe approach is to enable the
front port before you create any circuits and then retain the front port VLAN assignment afterwards. If
you break the rules when creating a circuit, or if you have to delete circuits and recreate them again,
delete all circuits and start over with the largest first.
