The value of thisargument must be a multiple of 100.DescriptionUse oam timer hello to configure the Ethernet OAM handshake packet transmission interval.Use undo oam timer hello to restore the default.By default, the Ethernet OAM handshake packet transmission interval is 1000 milliseconds.After the timeout timer for an Ethernet OAM connection expires, the local OAM entity ages out itsconnection with the peer OAM entity, causing the OAM connection to be disconnected. Therefore, H3Crecommends that you set the connection timeout timer at least five times the handshake packettransmission interval, ensuring the stability of Ethernet OAM connections.
