Any CES path can only be configured to operate in access mode. Each path has a configurable text description. The SONET/SDH signal label byte (C2) is configurable. The SONET/SDH path trace string (J1) is configurable. Payload scrambling cannot be enabled on CES paths. The valid SONET and SDH path configurations are shown in Table 1.

All SONET/SDH path alarms are configurable to be either enabled (the default) or disabled. The MTU size is configurable per path in the range of 512 to 2092. The path uses a default MTU size set to equal the largest possible CES packet size.
Load balancing options are not applicable to channelized CES paths.
When an Ethernet port is configured in WAN mode (xgig wan), you can change specific SONET/SDH parameters to reflect the SONET/SDH requirements for this port.
