Configuring Flood Rate Values - Alcatel OmniSwitch 6800 Series Network Configuration Manual

Setting Ethernet Parameters for All Port Types
To enable the maximum flood rate for multicast traffic on a slot enter interfaces followed by the slot
number and flood multicast. For example, to enable the maximum flood rate for multicast traffic on slot 2
enter:
-> interfaces 2 flood multicast
To enable the maximum flood rate for multicast traffic for a single port enter interfaces followed by the
slot number, a slash (/), the port number, and flood multicast. For example, to enable the maximum flood
rate for multicast traffic on port 3 on slot 2 enter:
-> interfaces 2/3 flood multicast
To enable the maximum flood rate for multicast traffic for a range of port enter interfaces followed by the
slot number, a slash (/), the first port number, a hyphen (-), the last port number, and flood multicast. For
example, to enable the maximum flood rate for multicast traffic on ports 3 through 4 on slot 2 enter:
-> interfaces 2/3-4 flood multicast
As an option, you can document the interface type by entering ethernet, fastethernet, or gigaethernet
before the slot number. For example, to enable the maximum flood rate for multicast traffic on slot 2 enter
and document the slot as Gigabit Ethernet enter:
-> interfaces gigaethernet 2 flood multicast
Note. Enabling the maximum multicast flood rate with the
IP Multicast Switching (IPMS) and non-IPMS multicast traffic.

Configuring Flood Rate Values

By default, the flood rate is 42 Mbps on 10/100/1000 ports and 496 Mbps on Gigabit ports. The
flood rate command can be used to configure the peak ingress flood rate value on a specific port, a range
of ports, or all ports on a switch (slot) in megabits per second.
Note. Although you can configure a flood rate equal to the line rate you should not do so. Alcatel recom-
mends that you always configure the flood rate to be less than the line speed.
To configure the peak flood rate for an entire slot enter interfaces followed by the slot number, flood rate,
and the flood rate in bytes. For example, to configure the peak flood rate on slot 2 as 42 bytes enter:
-> interfaces 2 flood rate 42
To configure the peak flood rate for a single port enter interfaces followed by the slot number, a slash (/),
the port number, flood rate, and the flood rate in bytes. For example, to configure the peak flood rate on
port 3 on slot 2 as 42 bytes enter:
-> interfaces 2/3 flood rate 42
To configure the peak flood rate for a range of ports enter interfaces followed by the slot number, a slash
(/), the first port number, a hyphen (-), the last port number, flood rate, and the flood rate in bytes. For
example, to configure the peak flood rate on ports 1 through 3 on slot 2 as 42 bytes enter:
-> interfaces 2/1-3 flood rate 42
