Features
The features added by this ZenPack can be summarized as follows. They are each detailed further below.
Discovery and periodic remodeling of Neighbor Switches using CDP/LLDP.
Monitoring of MAC Address table or Forwarding Table for each network interface of device.
Event suppression based on MAC Address table.
Discovery
CDP/LLDP based collector plugin zenoss.snmp.CDPLLDPDiscover performs discovery of switches located nearby a selected device.
Monitoring
The ZenPack binds Layer2Info monitoring templates to the /Network device class in Zenoss. This activates monitoring of Layer 2 MAC forwarding tables for devices under that class. On the detail view of Interfaces components, the Clients MAC addresses subpanel is added with a list of MAC addresses. Those addresses are grouped by the client device they belong to.
Event suppression
When an upstream switch goes down, a flood of Device is DOWN! events for every device in an affected subnet can be generated. This ZenPack adds a zenevent plugin which suppresses such subsequent events for leaf devices. As a result, a system administator receives only a primary, core error event.
