Interface And Hardware Component Configuration Guide For Cisco Ncs 5500 Series Routers, Ios Xr Release - Cisco NCS 5500 Series Configuration Manual

Configuring Ethernet OAM
DETAILED STEPS
Command or Action
Step 1
configure
Example:
RP/0/RP0/CPU0:router# configure terminal
Step 2 ethernet oam profile profile-name
Example:
RP/0/RP0/CPU0:router(config)# ethernet oam
profile Profile_1
Step 3
link-monitor
Example:
RP/0/RP0/CPU0:router(config-eoam)#
link-monitor
Step 4 symbol-period window { milliseconds window
| symbols window [ thousand | million | billion
]}
Example:
RP/0/RP0/CPU0:router(config-eoam-lm)#
symbol-period window 60000
Step 5
symbol-period threshold { ppm [ low threshold
] [ high threshold ] | symbols [ low threshold [
thousand | million | billion ]] [ high threshold [
thousand | million | billion ]]}
Example:
RP/0/RP0/CPU0:router(config-eoam-lm)#
symbol-period threshold symbols low
10000000 high 60000000
Step 6 frame window milliseconds window
Example:
RP/0/RP0/CPU0:router(config-eoam-lm)#
frame window milliseconds 60

Purpose
Enters global configuration mode.
Creates a new Ethernet Operations, Administration and Maintenance
(OAM) profile and enters Ethernet OAM configuration mode.
Enters the Ethernet OAM link monitor configuration mode.
(Optional) Configures the window size for an Ethernet OAM
symbol-period error event.
If specified in milliseconds, the range is 1000 to 60000. If not
specified as a multiple of 1 second, the actual window used will be
rounded up to the nearest second, with thresholds scaled accordingly.
If specified in symbols, the range is interface speed dependent (must
be between the maximum number of symbols that could be received
in 1 second and the maximum number of symbols that could be
received in 1 minute). Again the actual window used is rounded up
to the nearest second, with thresholds scaled accordingly.
The default value is 1000 milliseconds.
(Optional) Configures the thresholds that trigger an Ethernet OAM
symbol-period error event, in symbols or ppm (errors per million
symbols). When using this command at least one of the high and low
thresholds must be specified. If the low threshold is not specified, the
default value is used. If the high threshold is not specified, no action
is performed in response to an event. The high threshold must not be
smaller than the low threshold.
If specified in ppm, the range (for both thresholds) is 1 to 1000000.
If specified in symbols, the range (for both thresholds) is 1 to the
maximum window size in symbols, see
The default low threshold is 1 symbol.
(Optional) Configures the frame window size (in milliseconds) of an
OAM frame error event.
The range is from 1000 to 60000.
The default value is 1000.
