Configuring basic system parameters

These commands configure packet-based broadcast limiting on ports 1 – 8. On each port, the
maximum number of broadcast packets per second cannot exceed 65,536 packets per second.
On PowerConnect devices, multicast limiting is independent of broadcast limiting. To enable
multicast limiting on devices, enter commands such as the following.
PowerConnect(config)# interface ethernet 1 to 8
PowerConnect(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.
PowerConnect(config)# interface eth 1
PowerConnect(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
PowerConnect((config-if-e10000-1)#
Syntax: [no] broadcast limit <num>
Syntax: [no] unknown-unicast limit <num>
Syntax: [no]
or
Syntax: [no] multicast limit <num>
NOTE
The multicast limit <num> command applies to devices only.
The <num> variable specifies the maximum number of packets per second. Acceptable values
differ depending on the device you are configuring:
• On PowerConnect devices, <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.
PowerConnect(config)# interface ethernet 9
PowerConnectconfig-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
PowerConnect devices limit traffic based on kilobits per second (kbps). To enable limiting, refer to
the appropriate section, below.
PowerConnect devices
To enable broadcast limiting on a group of ports by counting the number of kilobits received, enter
commands such as the following.
PowerConnect(config)# interface ethernet 9 to 10
PowerConnect(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.
