Interfaces
Description This command configures whether the SONET/SDH port will reset when the path transitions to an opera-
tionally down state. This command only affects SONET/SDH ports on 7750 4-port OC48 SFP "-B" MDAs.
Default
no reset-port-on-path-down
section-trace
Syntax section-trace {increment-z0 | byte value | string string}
Context config>port>sonet-sdh
Description
This command configures the section trace bytes in the SONET section header to interoperate with some
older versions of ADMs or regenerators that require an incrementing STM ID. You can explicitly configure
an incrementing STM value rather than a static one in the SDH overhead by specifying the z0-increment.
Default byte 0x1
Parameters increment-z0 — Configure an incrementing STM ID instead of a static value.
byte value — Set values in SONET header bytes.
Default
Values
string string — Specifies a text string that identifies the section.
Values
speed
Syntax speed {oc3 | oc12}
no speed
Context config>port>sonet-sdh
Description This command configures the speed of a SONET/SDH port as either OC3 or OC12. The framer for this
MDA operates in groups of four. Changing the port speed for a port requires resetting the framer and causes
a slight disruption on all four ports. The first framer controls ports 1,2,3,4, the second framer controls ports
5,6,7,8 etc.
To change the port speed on a SONET/SDH port, the port must be administratively shut down and all chan-
nels must be removed. When the port speed is changed, the default channel configuration is recreated.
The no form of this command reverts back to default.
Default oc12
Parameters oc3 — set the speed of the port to OC-3.
oc12 — Set the speed of the port to OC-12.

0 — 255 or 0x00 — 0xFF
