Qos Port Dei - Alcatel-Lucent OmniSwitch 6850-48 Cli Reference Manual

qos port dei

Configures the Drop Eligible Indicator (DEI) bit mapping and marking setting for the specified QoS port.
The DEI setting applies to packets marked yellow (non-conforming) as the result of Tri-Color Marking
(TCM) rate limiting.
qos port slot/port dei {ingress | egress}
qos port slot/port no dei {ingress | egress}
Syntax Definitions
slot/port
ingress
egress
Defaults
By default, no DEI/CFI bit mapping or marking is done.
Platforms Supported
OmniSwitch 6400, 6850, 6850E, 6855, 9000E
Usage Guidelines
•
Use the no form of this command to disable the DEI bit mapping (ingress) or marking (egress) configu-
ration for the specified port
•
Use the qos dei command to set the global DEI bit mapping and marking configuration for all QoS
switch ports. Note that the port-level setting takes precedence over the global DEI setting.
•
Packets marked yellow by TCM rate limiting are still transmitted when there is no congestion on the
egress port queues. Setting the DEI/CFI bit for yellow egress packets (qos port dei egress) ensures that
an upstream switch is made aware that the packet was marked yellow.
•
When a switch receives a yellow packet with the DEI/CFI bit set and ingress DEI/CFI bit mapping is
enabled (qos port dei ingress), the packet is mapped to an internal drop precedence or yellow color
marking for the switch.
Examples
-> qos port 1/10 dei ingress
-> qos port 1/20 dei egress
-> qos port 1/10 no dei ingress
-> qos port 1/20 no dei egress

The slot number and port number of the physical port.
Maps the DEI/CFI bit to yellow (non-conforming) if this bit is set for
ingress packets.
Sets the DEI/CFI bit for egress packets if TCM marked the packets
yellow.
