GigaSMART Map Health Status

The health of a GigaSMART map is determined by the health of the following components:

■

All GigaSMART engine ports in the GigaSMART group (gsgroup)

■

Virtual ports (vport) associated with the GigaSMART group

■

GigaSMART operations

■

IP Interfaces

Refer to the following table to view the health status of a map with GigaSMART:

Color	Health Status	GigaSMART Group	vPort	GigaSMART Operations	IP Interfaces
Green	Up	Up	Up	Up	Up
Red	Down	Up	Down	Up	Up
Red	Down	Up	Up	Down	Up
Red	Down	Up	Up	Up	Down
Red	Down	Down	Down	Down	Down

GigaSMART Group Health Status

The health of a GigaSMART group (gsgroup) depends on the aggregated health of the associated GigaSMART engine ports. The following components contribute to the health of the GigaSMART engine ports:

■

Operational Status—The operational status of the associated GigaSMART engine ports. If the operational status of any GigaSMART engine port in the GigaSMART group is down, then the GigaSMART group becomes unhealthy.

■

GigaSMART Engine Port Packet Correlation—The percentage (%) of packet correlation seen in a GigaSMART engine port. The GigaSMART engine packet correlation is calculated based on the following factors:

o

the cumulative number of packets coming into a GigaSMART group

o

the cumulative number of packets going out of a GigaSMART interface

o

the cumulative number of packets dropped at a GigaSMART operation for a map

If the number of packets going out of a GigaSMART interface exceeds the threshold set in Administration > System > Traffic Health Thresholds, the GigaSMART engine port becomes unhealthy.

■

GigaSMART Engine Port Packet Drops—The cumulative number of packets dropped due to over subscription of a GigaSMART engine port. If the number of GigaSMART engine port packet drops exceed the threshold set in Administration > System > Traffic Health Thresholds, then the GigaSMART engine port becomes unhealthy.

■

GigaSMART Engine Port Packet Errors—The cumulative number of packet errors coming into a GigaSMART engine port. If the number of GigaSMART engine port packet errors exceed the threshold set in Administration > System > Traffic Health Thresholds, then the GigaSMART engine port in the GigaSMART group becomes unhealthy.

For information about setting traffic health thresholds, refer to the “Traffic Health Thresholds” section in the GigaVUE Administration Guide. All threshold types are enabled by default for computing the health status of the GigaSMART engine ports.

In this example, the thresholds are enabled and the threshold values are set as follows:

Type	Threshold Value	Interval
GigaSMART engine port packet correlation	50	15
GigaSMART engine port packet drops	15000	15
GigaSMART engine port packet errors	15000	15

Refer to the following table to view how the GigaSMART engine port health status is calculated.

Color	Health Status	Operational Status	Packet Correlation	Packet Drops over 15 min	Packet Errors over 15 min
Green	Up (healthy)	Up	< 50	< 15000	< 15000
Red	Down (unhealthy)	Down	-	-	-
Red	Down (unhealthy)	Up	> 50	< 15000	< 15000
Red	Down (unhealthy)	Up	< 50	> 15000	< 15000
Red	Down (unhealthy)	Up	< 50	< 15000	> 15000

The GigaSMART group health status is determined by the aggregated health of the GigaSMART engine ports. Refer to the following table for computing the health of a GigaSMART group:

Color	GigaSMART Group Health	GigaSMART Engine Ports
Green	Up	Up
Amber	Warning	Some engine ports are down
Red	Down	All engine ports are down

vPort Health Status

GigaSMART virtual port is used as an aggregation point for traffic directed to second level maps. Second level maps include an Adaptive Packet Filtering component or a GTP rule.

A vPort is healthy when the GigaSMART group associated with the vPort is healthy. If a gsgroup is unhealthy and the vPort is healthy, this indicates that the vPort is not participating in the maps.

GigaSMART Operations Health Status

GigaSMART Operation consists of one or more advanced processing applications.

A GigaSMART operation (gsop) is healthy when the GigaSMART group associated with the gsop is healthy. If a gsgroup is unhealthy and the gsop is healthy, this indicates that the gsop is not participating in the maps.

IP Interfaces Health Status

IP interfaces are used for GigaSMART encapsulation and decapsulation operations on both network ports and tool ports.

An IP interface is healthy when the GigaSMART group associated with the IP interface is healthy. If a gsgroup is unhealthy and the IP interface is healthy, this indicates that the IP interface is not participating in the maps.
