ssm
Syntax ssm
Context config>port>ethernet
Description This command enables Ethernet Synchronous Status Message (SSM).
network-type
Syntax network-type [sonet | sdh]
Context config>port>ethernet>ssm
Description This command configures the encoding of synchronous status messages. For example, whether to use an
SDH or SONET set of values. Configuring the network-type is only applicable to SyncE ports. It is not
configurable on SONET/SDH ports. For the network-type, sdh refers to ITU-T G.781 Option I, while sonet
refers to G.781 Option II (equivalent to Telcordia GR-253-CORE). For compatibility with Release 7.0, sdh
is the default.
Default sdh
Parameters sdh — Specifies the values used on a G.781 Option 1 compliant network.
sonet — Specifies the values used on a G.781 Option 2 compliant network.
tx-dus
Syntax [no] tx-dus
Context config>port>ethernet>ssm
config>port>sonet-sdh
Description This command forces the QL value transmitted from the SSM channel of the SONET/SDH port or the
Synchronous Ethernet port to be set to QL-DUS/QL-DNU. This capability is provided to block the use of
the interface from the SR/ESS for timing purposes.
Default
no tx-dus
xgig
Syntax xgig {lan |wan}
Context config>port>ethernet
Description
This command configures a 10 Gbps interface to be in Local or Wide Area Network (LAN or WAN) mode.
When configuring the port to be in WAN mode certain SONET/SDH parameters can be changed to reflect
the SONET/SDH requirements for this port.
