Egress buffer thresholds for QoS priorities
Modifying system parameter default values
Information for the configurable tables appears under the columns that are shown in bold type in
the above examples. To simplify configuration, the command parameter you enter to configure the
table is used for the table name. For example, to increase the capacity of the IP route table, enter
the following commands.
TurboIron(config)#system-max ip-route 120000
TurboIron(config)#write memory
TurboIron(config)#exit
TurboIron#reload
Syntax: system-max ip-route
The parameter specifies the maximum number of routes in the IP route table. The
minimum value is 4096. The default is 80000 IP routes.
NOTE
If you accidentally enter a value that is not within the valid range of values, the CLI will display the
valid range for you.
Egress buffer thresholds for QoS priorities
NOTES:
• The terms QoS priority and traffic class are used interchangeably in this section and
mean the same thing.
• Buffer threshold level-3 to maximum does not change the buffering behavior of the
device in release 04.2.00 and later.
The switch uses egress buffer threshold levels to dynamically adjust each port egress queue
(outbound transmit queue) based on QoS priority (traffic class) and jumbo frame support. When
the egress buffer queue is full, any new packets destined for the egress queue will be dropped.
The following egress buffer thresholds can be adjusted by an administrator:
• Egress Buffer Threshold for all Traffic Classes for a port – When this is configured, the
specified egress buffer threshold will be applied to all traffic classes (0 – 7) on a port.
