ipqos config
Configure Internet Protocol (IP) Quality of Service (QoS) for a given destination interface for the IP QoS queues
instantiation.
Note When enabling/disabling of IP QoS, take the following into account:
• if the WAN interface (e.g. PPPoA, IPoA, ...) is detached at the time of enabling/disabling IP QoS, then
the WAN interface has to be attached in order for the enabling/disabling of IP QoS to take effect.
• if the WAN interface is attached at the time of enabling/disabling IP QoS, then the WAN interface has
to be detached and then re-attached in order for the enabling/disabling of IP QoS to take effect.
SYNTAX:
where:
ipqos config dest = <string>
[state = <{disabled|enabled}>]
[discard = <{tail|early}>]
[realtimerate = <number{1-100}>]
[burstsize = <number{1-128}>]
[maxpackets = <number{0-100}>]
[maxbytes = <number{0-128}>]
dest The destination interface for the IP QoS queues instantiation.
Typically, a phonebook entry.
REQUIRED
state This parameter enables or disables IP QoS for the interface.
The default is disabled.
OPTIONAL
discard Determines the packet discard strategy in case of congestion.
Choose between:
• tail:
Tail Drop: arriving packets will be dropped as soon as the
destination queue is in an overflow state.
• early:
Early Packet discard: arriving packets will be dropped early
according to the BLUE active queue management algorithm.
The default is early.
OPTIONAL
realtimerate A number between 1 and 100.
Represents a percentage of the interface bandwidth for rate-limiting of
the Real Time queue.
In case of congestion, the Real Time queue will only use this percentage of
the interface bandwidth when there is also traffic on the other queues.
The default is 80.
OPTIONAL
burstsize A number between 1 and 128.
Represents the realtime queue burstsize (in kilobytes) for rate limiting.
OPTIONAL
maxpackets A number between 0 and 100.
Represents the maximum number of packets in all IP QoS queues
instantiated for one interface.
