Label Config - THOMSON 516 Reference Manual

label config

Configure a label.
SYNTAX:
label config name = <string>
[classification = <{ignore | overwrite | increase}>]
[defclass = <number{0-15}>]
[ackclass = <number{0-15}>]
[ttloverwrite = <{disabled | enabled}>]
[ttl = <number{0-255}>]
[tosmarking = <{disabled | enabled}>]
[tos = <number{0-255}>]
[trace = <{disabled | enabled}>]
where:
name The name of the label to be configured.
classification Select the method of classification, in other words determine what the Layer 3
class assigment must do with the priority of the data packet (as set by Layer 2).
Choose between:
ignore: Ignore the class parameters (defclass and ackclass), but use the class
as set by Layer 2 (Virtual LAN (VLAN) user priority, ATM QoS).
overwrite: Change the class to defclass/ackclass, overwriting the value set
by Layer 2 (VLAN user priority, ATM QoS).
increase: Change the class according to defclass/ackclass, but only if the
defclass value is higher than the class value already set by Layer 2.
The default is ignore.
Note
defclass A number between 0 and 15.
Represents the default priority class of the assigned connection.
The default is 0.
ackclass A number between 0 and 15.
Represents the priority class of the ACK segments of the TCP connection.
The default is 0.
ttloverwrite Enable or disable ttl overwrite.
When on forwarding the TTL field of the IP header is decremented, an
Internet Group Management Protocol (IGMP) packet with TTL=1 would be
dropped.
To support forwarding of IGMP packets, the TTL value can be overwritten.
The default is disabled.
E-DOC-CTC-20040907-0010 v1.0
The class as set by Layer 2 is derived from:
the VLAN user priority (in case of VLAN or priority tagged frames)
the ATM PVC QoS class (in case the packet is received from an
ATM PVC).
For non-VLAN frames or non-PVC received data, Layer 2 sets the
internal class (priority) to 4 by default.
