configuration changes have occurred, which might require the peer OAM entity to re-evaluate whether
OAM peering is allowed.
(6) OAM mode change.
(7) OAM Functions Supported: The OAM functions supported on this port. These functions include:
1. Unidirectional: It indicates that the OAM entity supports the transmission of
OAMPDUs on links that are operating in unidirectional mode (traffic flowing in one
direction only).
2. Loopback: It indicates that the OAM entity can initiate and respond to loopback
commands.
3. Link Monitoring: It indicates that the OAM entity can send and receive Event
Notification OAMPDUs.
4. Variable: It indicates that the OAM entity can send and receive variable requests to
monitor the attribute value as described in the IEEE 802.3 Clause 30 MIB.
The event log displays Ethernet OAM event log information. The switch can buffer 1000 event logs.
The event log is different from sys-log as it provides more detailed information than sys-log. Each
OAM event will be recorded in both OAM event log and syslog.
