There are still some ACL commands related to multicast application. Please refer to Table 91 on
page 134 or search “acl multicast” directly.
13.1.1 Command Examples
Note: Before you can use an interface, you have to activate (provision) the corresponding
slot. See Section 12.1.1 on page 107 for how to activate a slot.
This example shows how to create an ACL profile named EXAMPLE to prioritize specific traffic. This
example classifies SMTP packets (port 25 is the most common port used by SMTP) sending from a
host with an IP address 192.168.1.100 and then sends the matched packets to queue 1.
13.2 Broadcast Storm Commands
Use these commands to limit the number of broadcast, multicast and destination lookup failure
(DLF) packets (unknown unicast and multicast packets) the IES receives per second on the ports.
When the number of broadcast, multicast and/or DLF packets reaches the maximum allowed per
second, the IES discards subsequent packets. Enable this feature to reduce broadcast, multicast
and/or DLF packets in your network. You can specify limits for DLF and broadcast packets.
