Configuring the device as an SNTP server
Brocade# config terminal
Brocade(config)# interface ethernet 13
Brocade(config-if-e1000-13)# unknown-unicast limit 65536 bytes
The combined number of bytes of inbound Unknown Unicast packets
permitted for ports 13 to 24 is now set to 65536
Brocade((config-if-e1000-13)#
Syntax: [no] broadcast limit <num> bytes
Syntax: [no] multicast limit
Syntax: [no] unknown-unicast limit <num> bytes
The <num> variable 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 limit
you specify. 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. The unknown-unicast limit <num> bytes command is supported on FSX and FESX devices.
Viewing broadcast, multicast, and unknown unicast limits
You can use the show run interface command to display the broadcast, multicast, and
unknown-unicast limits configured on the device.
You can use the following commands, in addition to the show run interface command, to display
the broadcast, multicast, and unknown-unicast limits configured on the device:
• show rate-limit unknown-unicast
• show rate-limit broadcast
NOTE
The show rate-limit unknown-unicast command is only supported on FSX and FESX devices.
Use the show run interface command to view the broadcast, multicast, and unknown-unicast limit
configured on each port.
