Configuring basic system parameters
On TurboIron X Series devices, multicast limiting is independent of broadcast limiting. To enable
multicast limiting on devices, enter commands such as the following.
TurboIron(config)#interface ethernet 1 to 8
TurboIron(config-mif-e10000-1-8)#multicast limit 65536
To enable unknown unicast limiting by counting the number of packets received, enter commands
such as the following.
TurboIron(config)#interface eth 1
TurboIron(config-if-e10000-1)#unknown-unicast limit 65536
The combined number of inbound Unknown Unicast packets permitted
for ports 1 to 12 is now set to 65536
TurboIron((config-if-e10000-1)#
Syntax: [no] broadcast limit <num>
Syntax: [no] unknown-unicast limit <num>
Syntax: [no]
or
Syntax: [no] multicast limit
NOTE
The multicast limit > command applies to devices only.
The variable specifies the maximum number of packets per second. Acceptable values
differ depending on the device you are configuring:
• On TurboIron X Seriesdevices, <num> can be any number between 1 and 8388607 (packets
per second). The actual value will be determined by the system. Once you enter the value, the
CLI will display a message indicating the actual value. The following shows an example
configuration.
TurboIron(config)#interface ethernet 9
TurboIronconfig-mif-e10000-9)#multicast limit 50
Multicast limit in pkts/sec set to 31
If you specify 0, limiting is disabled. Limiting is disabled by default.
Command syntax for byte-based limiting
TurboIron X Series devices limit traffic based on kilobits per second (kbps). To enable limiting, refer
to the appropriate section, below.
TurboIron X Series devices
To enable broadcast limiting on a group of ports by counting the number of kilobits received, enter
commands such as the following.
TurboIron(config)#interface ethernet 9 to 10
TurboIron(config-mif-e10000-9-10)#broadcast limit 131072 kbps
Broadcast limit in kbits/sec set to 130000
These commands configure broadcast limiting on ports 9 and 10. On each port, the total number
of kilobits received from broadcast packets cannot exceed 130,000 per second.
To enable multicast limiting, enter commands such as the following.
