View the Forwarding States of Inline Networks

To view the forwarding states of inline networks in the flexible inline canvas, choose the required inline network, and then click Status. Refer to the following figure.

Figure 56

Inline Network Forwarding States

Following inline network states are not explicitly shown in the flexible inline canvas:

■

Normal—If the state of all inline tools are up, the inline network is in Normal state.

■

Abnormal—If any inline tool involved in flexible inline maps (directly or indirectly as a member of an inline tool group) is operationally down and there is no network-level failover action in effect, the inline network is in an Abnormal state.

Following table provides the list of forwarding states of inline network and their description.

Far-End Status of Links Connected to Inline Network Ports

Operational State of Not Forced Inline Tools and Inline Tool Groups Involved in Maps from the Inline Network

Forwarding State

Description

enable

any inline network traffic path configuration

any combination of far-end ports status

any combination of operational state of the inline tools or inline tool groups involved in the maps originating from the inline network

PHYSICAL BYPASS

all traffic exchanged directly between the end nodes without being noticed by the switching fabric (GigaVUE node acting as a wire or fiber)

disable

traffic path set to drop

any combination of far-end ports status

any combination of operational state of the inline tools or inline tool groups involved in the maps originating from the inline network

DISABLED

all traffic arriving at the inline network ports is dropped

disable

traffic path set to bypass, monitoring, or to-inline-tool

at least one far-end port is down

any combination of operational state of the inline tools or inline tool groups involved in the maps originating from the inline network

DISCONNECTED

No traffic is exchanged between the nodes

disable

traffic path set to bypass

both far-end ports are up

any combination of operational state of the inline tools or inline tool groups involved in the maps originating from the inline network

FORCED BYPASS

All traffic that matches any of the maps originating from the inline network is redirected through a logical bypass

disable

traffic path set to monitoring

both far-end ports are up

any combination of operational state of the inline tools or inline tool groups involved in the maps originating from the inline network

FORCED BYPASS WITH MONITORING

A copy of the traffic originating from the inline network bypasses the sequence of inline tools and inline tool groups and is re-directed to the opposite-side inline network port. Another copy of the traffic is directed to the sequence of inline tools and inline tool groups, except that no traffic of the second copy is sent to the exit port.

disable

traffic path set to to-inline-tool

both far-end ports are up

all inline tools involved (directly or indirectly as members of inline tool groups) in the maps originating from the inline network are in the up operational state

NORMAL

The traffic is guided between the source leader in a bidirectional clock relationship (formerly master) inline network port and the destination inline network port according to the status of the inline tools and inline tool groups.

Note: The state of all inline tools must be up, including inline tools configured as spare in an inline tool group, inline tools or inline tool group members in the a-to-b and b-to-a lists configured with any traffic path other than to-inline-tool.

disable

traffic path set to to-inline-tool

both far-end ports are up

at least one of the inline tools or inline tool groups involved in the maps originating from the inline network configured with the traffic path parameter to-inline-tool and failover action of network-port- forced-down is in the down operational state

NETWORK PORTS FORCED DOWN

No traffic is exchanged between the inline network ports, and the inline network ports are brought down

disable

traffic path set to to-inline-tool

both far-end ports are up

none of the inline tools or inline tool groups involved in the maps originating from the inline network configured with to-inline-tool and failover action network-port-forced- down is in the down operational state

at least one of the inline tools or inline tool groups involved in the maps originating from the inline network configured with to-inline-tool and failover-action of network-drop is in the down operational state

FAILURE INTRODUCED DROP

All traffic arriving at the inline network ports is dropped

disable

traffic path set to to-inline-tool

both far-end ports are up

none of the inline tools or inline tool groups involved in the maps originating from the inline network configured with to-inline-tool and failover action of network-port-forced- down or network-drop is in the down operational state

at least one of the inline tools or inline tool groups involved in the maps originating from the inline network configured with to-inline-tool and failover action of network-bypass is in the down operational state

FAILURE INTRODUCED BYPASS

All traffic that matches any of the maps originating from the inline network is redirected through a logical bypass

disable

traffic path set to to-inline-tool

both far-end ports are up

any combination of conditions not listed for the forwarding state definitions of PHYSICAL BYPASS, DISABLED, DISCONNECTED, FORCED BYPASS, FORCED BYPASS WITH MONITORING, NORMAL, NETWORK PORTS FORCED DOWN, FAILURE-INTRODUCED DROP, or FAILURE-INTRODUCED BYPASS

ABNORMAL

The traffic is guided between the source inline network port according to the status of the inline tools and inline tool groups

Note: If any inline tool involved in flexible inline maps (directly or indirectly as a member of an inline tool group) is in the down operational state and there is no network-level failover action in effect, the inline network is in the ABNORMAL state.
