ips netsim reorder
ips netsim reorder
To reorder packets entering a specified Gigabit Ethernet interface, use the ips netsim reorder command
in SAN extension tuner configuration submode.
ips netsim reorder {nth packet distance dist-packet ingress gigabitethernet slot/port | nth packet
ingress gigabitethernet slot/port} | {random percent distance dist-packet ingress
gigabitethernet slot/port | random percent ingress gigabitethernet slot/port}
Syntax Description|
Defaults Disabled.
Command Modes SAN extension tuner configuration submode.
Command History
Usage Guidelines To use this command, you must enable the IP Network Simulator using the ips netsim enable command.
You can configure network simulator to reorder packets (even when the queue is not full) randomly
(specified as a percentage) or every Nth packet. Percentage is represented as the number of packets in
10,000. For example, if you want to reorder one percent of packets, then specify it as 100 packets in
10,000. To simulate a realistic scenario for IP networks using random reordering, the percentage should
be between zero and one percent of packet reordered in the specified traffic direction.
If you use the optional burst parameter, then the specified number of packets will be reordered. If you
do not specify the burst parameter, then only one packet is reordered.
Examples The following example shows reordering at 50 percent with a distance limit of 5.
switch# config terminal
switch(config)#
switch(config)# san-ext-tuner enable
switch(config)# exit
switch#
switch# ips netsim reorder random 50 distance 5 ingress gigabitethernet 2/3
nth packet Specifies a specific packet reordered. The range is 0 to 10,000.
distance dist-packet Specifies the distance between the packet to be reordered and the packet at
the head of the queue. The range is 1 to 10.
ingress Specifies the ingress direction.
gigabitethernet
slot/port
Specifies the the slot and port number of the Gigabit Ethernet interface.
random percent Specifies the percentage of packets passed before a reorder. The range is 0 to
10,000.
