R21xx-HP FlexFabric 11900 High Availability Configuration Guide
5
OAM connections stable, HP recommends that you set the connection timeout timer at least five times the
handshake packet transmission interval.
To configure the Ethernet OAM connection detection timers globally:
Ste
p
Command
Remarks
1. Enter system view.
System-view N/A
2. Configure the Ethernet OAM
handshake packet
transmission interval.
oam global timer hello interval The default is 1000 milliseconds.
3. Configure the Ethernet OAM
connection timeout timer.
oam global timer keepalive
interval
The default is 5000 milliseconds.
To configure the Ethernet OAM connection detection timers on a port:
Ste

Command
Remarks
1. Enter system view.
System-view N/A
2. Enter Layer 2/Layer 3 Ethernet
port view.
interface interface-type
interface-number
N/A
3. Configure the Ethernet OAM
handshake packet
transmission interval.
oam timer hello interval
By default, an interface uses the
value configured globally.
4. Configure the Ethernet OAM
connection timeout timer.
oam timer keepalive interval
By default, an interface uses the
value configured globally.
Configuring link monitoring
After Ethernet OAM connections are established, the link monitoring periods and thresholds configured
in this section automatically take effect on all Ethernet ports.
Configuring errored symbol event detection
An errored symbol event occurs when the number of detected symbol errors in the detection window
(specified number of received symbols) exceeds the predefined threshold.
You can configure this command in system view or port view. The configuration in system view takes effect
on all ports, and the configuration in port view takes effect on the specified port. For a port, the
configuration in port view takes precedence.
To configure errored symbol event detection globally:
Ste
p
Command
Remarks
1. Enter system view.
system-view N/A
2. Configure the errored symbol
event detection window.
oam global errored-symbol-period
window window-value
By default, the errored symbol
event detection window is
100000000.
3. Configure the errored symbol
event triggering threshold.
oam global errored-symbol-period
threshold threshold-value
By default, the errored symbol
event triggering threshold is 1.
