Not all packets received on a port have high priority. IGMP and BPDU
packets have high priority by default.
The Magnum 6K family of switches has the capability to set the priorities based on three
different functions. They are
Port QoS
: assigns a high priority to all packets received on a port, regardless of the type of
packet.
TAG QoS
: if a packet contains a tag, the port on which the packet was received then looks
to see at which level that tag value is set. Regardless of the tag value, if there is a tag, that
packet is automatically assigned high priority (sent to the high priority queue)
ToS QoS
: (Layer 3) when a port is set to ToS QoS, the most significant 6-bits of the IPv4
packet (which has 64 bits) are used. If the 6 bits are set to ToS QoS for the specific port
number the packet went to, that packet is assigned high priority by that port
Configuring QoS
Magnum 6K family of switches support three types of QoS - Port based, Tag based and ToS
based.
QoS is disabled by default on the switch. QoS needs to be enabled and
configured.
Syntax
qos –
enter the QoS configuration mode
Syntax
setqos type=<port|tag|tos|none> [port=<port|list|range>]
[priority=<high|low>] [tos=<0-63|list|range>][tag=<0-7|list|range>]
-
depending on the type of QOS, the corresponding field has to be set. For example, for QOS type tag,
the tag levels have to be set, and for QOS type ToS, the ToS levels have to be set. If the priority field
is not set, it then defaults to low priority. ToS has 64 levels and the valid values are 0-63 and a
tagged packet has 8 levels and the valid values are 0-7.
Setting type to none will clear the QoS settings
