Configuring the Ethernet OAM connection detection timers After an Ethernet OAM connection is established, the Ethernet OAM entities exchange Information OAMPDUs at the handshake packet transmission interval to detect the availability of the Ethernet OAM connection. If an Ethernet OAM entity receives no Information OAMPDU within the Ethernet OAM connection timeout time, the Ethernet OAM connection is considered disconnected. By adjusting the handshake packet transmission interval and the connection timeout timer, you can change the detection time resolution for Ethernet OAM connections. You can configure this command in system view or interface view. The configuration in system view takes effect on all ports, and the configuration in interface view takes effect on the specified port. For a port, the configuration in interface view takes precedence. After the timeout timer of an Ethernet OAM connection expires, the local OAM entity ages out its connection with the peer OAM entity, causing the OAM connection to disconnect. To keep the Ethernet OAM connections stable, HP recommends that you set the connection timeout timer at least five times higher than the handshake packet transmission interval. To configure the Ethernet OAM connection detection timers globally: Step 1. Enter system view. 2. Configure the Ethernet OAM handshake packet transmission interval. 3. Configure the Ethernet OAM connection timeout timer. Command System-view oam global timer hello interval oam global timer keepalive interval Remarks N/A The default is 1000 milliseconds. The default is 5000 milliseconds. To configure the Ethernet OAM connection detection timers on a port: Step 1. Enter system view. 2. Enter Ethernet interface view. 3.

Command System-view interface interface-type interface-number oam timer hello interval oam timer keepalive interval Remarks N/A N/A By default, an interface uses the value configured globally. By default, an interface uses the value configured globally.

Configuring the Ethernet OAM connection
detection timers
After an Ethernet OAM connection is established, the Ethernet OAM entities exchange Information
OAMPDUs at the handshake packet transmission interval to detect the availability of the Ethernet OAM
connection. If an Ethernet OAM entity receives no Information OAMPDU within the Ethernet OAM
connection timeout time, the Ethernet OAM connection is considered disconnected.
By adjusting the handshake packet transmission interval and the connection timeout timer, you can
change the detection time resolution for Ethernet OAM connections.
You can configure this command in system view or interface view. The configuration in system view takes
effect on all ports, and the configuration in interface view takes effect on the specified port. For a port,
the configuration in interface view takes precedence.
After the timeout timer of an Ethernet OAM connection expires, the local OAM entity ages out its
connection with the peer OAM entity, causing the OAM connection to disconnect. To keep the Ethernet
OAM connections stable, HP recommends that you set the connection timeout timer at least five times
higher than the handshake packet transmission interval.
