Command syntax for packet-based limiting on Brocade ICX 6610 and 6450
devices
To enable broadcast limiting on a group of ports by counting the number of bytes received, enter
commands such as the following.
Brocade(config)# interface ethernet 1/1/1 to 1/1/8
Brocade(config-mif-e1000-1/1/1-1/1/8)# broadcast limit 8192
To include unknown-unicast limiting, enter the unknown-unicast limit command after enabling
broadcast limiting.
Brocade(config-mif-e1000-1/1/1-1/1/8)# unknown-unicast limit
To include multicasts limiting, enter the multicast limit command after enabling broadcast limiting.
Brocade(config-mif-e1000-1-8)# multicast limit
Syntax: [no]broadcast limit <num>
Syntax: [no] multicast limit
Syntax: [no] unknown-unicast limit
The <num> variable specifies the maximum number of Kilo bytes per second. It can be any number
that is a multiple of 8192, up to a maximum value of 2147418112. If you enter the multicast limit
or unknown-unicast limit command, multicast or unknown-unicast packets are included in the
corresponding limit. If you specify 0, limiting is disabled. If you specify a number that is not a
multiple of 8192, the software rounds the number to the next multiple of 8192. Limiting is disabled
by default.
Command syntax for byte-based limiting
NOTE
Byte-based limiting is supported on FSX and FESX devices only. Byte-based limiting is not supported
on the FastIron WS, Brocade FCX Series, ICX 6430 devices and the SX-FI48GPP module.
Byte-based limiting provides the ability to rate limit traffic based on byte count. When the byte
mode is enabled, packets will be received on a port as long as the number of bytes received per
second is less than the corresponding limit. Once the limit is reached, further packets will be
dropped.
To enable broadcast limiting on a group of ports by counting the number of bytes received, enter
commands such as the following.
Brocade(config)# interface ethernet 9 to 10
Brocade(config-mif-e1000-9-10)# broadcast limit 131072 bytes
These commands configure byte-based broadcast limiting on ports 9 and 10. On each port, the
total number of bytes received from broadcast packets cannot exceed 131,072 per second.
To include multicasts in the 131072 bytes per second limit on each of the ports, enter the multicast
limit command after enabling broadcast limiting.
Brocade(config-mif-e1000-1-8)# multicast limit
To enable unknown unicast limiting, enter commands such as the following.
