Configuration Commands
speed
Syntax speed {10 | 100 | 1000}
Context config>port>ethernet
Description This command configures the port speed of a Fast Ethernet port when autonegotiation is disabled. If
the port is configured to autonegotiate this parameter is ignored. Speed cannot be configured for ports
that are part of a Link Aggregation Group (LAG).
Default
100
Parameters
10 — Sets the link to 10 mbps speed.
100 — Sets the link to 100 mbps speed.
1000 — Sets the link to 1000 mbps speed.
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
