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 limitnumbytes command is supported on FSX 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 supported only on FSX and the ICX 7750 devices.
Use the show run interface command to view the broadcast, multicast, and unknown-unicast limit
configured on each port.
