Configuring sFlow Maximum Header Size

1. Enter GigabitEthernet Interface Configuration mode:

   enable

   configure terminal

   interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

   

   Note

   If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

2. Configure the maximum-header size:

   sflow max-header-size <64–256>

3. Verify the configuration:

   show sflow interface {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}

Example

For ports 1/1 to 1/10, configure the maximum header size, and then verify the configuration.

Switch:1(config-if)#interface gigabitethernet 1/1-1/10
Switch:1(config-if)#sflow max-header-size 255
Switch:1(config-if)#show sflow interface 1/1-1/10
