Interface Configuration
7750 SR Interface Configuration Guide Page 419
Description This command enables packet gathering and redirection of IP packets from a single fiber (RX) port of the
Ethernet or SONET/SDH interface and redistributes packets to other interfaces through either static routes
or policy-based forwarding.
This parameter can be applied in conjunction with the strip-label command. If they are applied together, the
port must have the single-fiber option configured before it can be associated with an interface that is config-
ured with the strip-label option.
Once a port is configured with single-fiber, traffic will no longer be transmitted out of that port.
Default no single-fiber
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).
code-type
Syntax code-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 con-
figurable 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.
