Configuring the device as an SNTP server
Brocade(config)# interface ethernet 1
Brocade(config-if-e1000-1)# unknown-unicast limit 65536
The combined number of inbound Unknown Unicast packets permitted
for ports 1 to 12 is now set to 65536
Brocade((config-if-e1000-1)#
NOTE
On the SX-FI48GPP module, multicast and unknown-unicast limiting use the value defined in
broadcast limiting. You cannot set a separate limit for unknown-unicast limiting and multicast
limiting.
Syntax: [no] broadcast limit <num>
Syntax: [no] multicast limit
Syntax: [no] unknown-unicast limit <num>
The <num> variable specifies the maximum number of packets 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 packets or unknown-unicast limit 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 packet-based limiting on FastIron WS and Brocade FCX
Series and ICX 6430 devices
To enable broadcast limiting on a group of ports by counting the number of packets 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 65536
To include unknown unicast limiting by counting the number of packets received, enter commands
such as the following.
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 packets per second. It can be any number
that is a multiple of 65536, up to a maximum value of 2147418112. If you enter the multicast limit
command, multicast 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 65536, the software rounds the number
to the next multiple of 65536. Limiting is disabled by default.
