Brocade Communications Systems 6650 manual Changing the sampling rate for a trunk port

11 sFlow

To change the sampling rate on an individual port, enter a command such as the following at the configuration level for the port.

Brocade(config-if-1/1)#sflow sample 8192

Syntax: [no] sflow sample <num>

The <num> parameter specifies the average number of packets from which each sample will be taken. The software rounds the value you enter up to the next odd power of 2. The actual sampling rate becomes one of the values listed in “Changing the default sampling rate”.

NOTE

Configuring a sampling rate on a port that is the primary port of a trunk applies that same sampling rate to all ports in the trunk.

Changing the sampling rate for a trunk port

You can configure an individual static trunk port to use a different sampling rate than the global default sampling rate. This feature is also supported on LACP trunk ports. This feature is useful in cases where ports have different bandwidths. For example, if you are using sFlow on 10/100 ports and Gbps Ethernet ports, you might want to configure the Gbps ports to use a higher sampling rate (and thus gather fewer samples per number of packets) than the 10/100 ports.

To configure a static trunk port to use a different sampling rate than the global default sampling rate, enter commands such as the following:

Brocade(config)#trunk e 1/1/1 to 1/1/2

Brocade(config-trunk-1/1/1-1/1/2)sflow sample 8192

Syntax: [no] sflow sample <num>

The <num> parameter specifies the average number of packets from which each sample will be taken. The software rounds the value you enter up to the next odd power of 2. The actual sampling rate becomes one of the values listed in “Changing the default sampling rate”.

NOTE

Configuring a sampling rate on only the port that is the primary port of a trunk automatically applies that same sampling rate to all ports in the trunk.
