Port Groups And Maximum Bandwidth - Alcatel OmniSwitch 6624 Network Configuration Manual

Using Condition Groups in Policies
This command specifies that port 2/1 will be deleted from the techpubs port group at the next qos apply.
To delete a port group, use the no form of the policy port group command with the relevant port group
name. The port group must not be associated with any policy condition. For example:
-> no policy port group techpubs
The port group techpubs will be deleted at the next qos apply. If techpubs is associated with a policy
condition, an error message will display instead:
ERROR: techpubs is being used by condition 'cond4'
In this case, remove the port group from the condition first; then enter the no policy port group
command. For example:
-> policy condition cond4 no source port group
-> no policy port group techpubs
The policy condition command removes the port group from the policy condition. (See
Conditions" on page 21-24
be deleted at the next qos apply.

Port Groups and Maximum Bandwidth

On the OmniSwitch 6624/6648, if a policy is configured with a port group in the condition and a policy
action with maximum bandwidth, the bandwidth sent out over the ports in the port group is distributed
over the active ports in a source port group. (This functionality is different from the OmniSwitch 7700/
7800/8800, which allows each port in a port group the maximum bandwidth.)
For destination port groups, the bandwidth is sent out differently depending on the physical location of the
ports. Any ports in the destination port group that reside in the same slot and physical grouping (up to 24
ports) will have the bandwidth distributed among the ports; any ports that reside in a different slot and/or
different physical port grouping each will be allowed the maximum bandwidth.
On the OmniSwitch 6624/6648, ports are grouped in blocks of 24; each "slot" is an individual
OmniSwitch in a stack of switches.

Source Port Group Example
In the following example, a port group (pgroup) is created with two ports and attached to a policy condi-
tion (Ports). A policy action with maximum bandwidth is created (MaxBw). The policy condition and
policy action are combined in a policy rule called PortRule.
-> policy port group pgroup 1/1-2
-> policy condition Ports source port group pgroup
