network segment where the system collects the statistics. No ACLI or EDM support exists to add or
delete entries in this table.
Address map MIB
The address map MIB maps the network layer IP to the MAC layer address.
The system populates the address map control table MIB with an entry for each host interface that
you enable for monitoring on the switch.
Network layer host MIB
The network layer host MIB monitors the Layer 3 traffic statistics for each host. The network layer
host MIB monitors traffic packets in and out of hosts based on the network layer address. The
network layer host controls the network and application layer host tables.
The system populates an entry for the management IP of the switch to represent the network
segment where the system collects the statistics. You have to enable each host interface that you
want to monitor on the switch.
The system only collects statistics for this group from packets that go to the CP.
Application layer host MIB
The application layer host MIB monitors traffic statistics by application protocol for each host.
The system populates an entry for the management IP of the switch to represent the network
segment where the system collects the statistics. You have to enable each host interface that you
want to monitor on the switch.
The system only collects statistics for this group from packets that go to the CP.
Link state change control
Rapid fluctuation in a port link state is called link flapping.
Link flapping is detrimental to network stability because it can trigger recalculation in spanning tree
and the routing table.
If the number of port down events exceeds a configured limit during a specified interval, the system
forces the port out of service.
You can configure link flap detection to control link state changes on a physical port. You can set
thresholds for the number and frequency of changes allowed.
You can configure the system to take one of the following actions if changes exceed the thresholds:
• send a trap
• bring down the port
If changes exceed the link state change thresholds, the system generates a log entry.
