Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 652)

To distinguish collected packets in different VRFs, refer to the in vlan and out vlan data fields for
each captured ingress packet. For example, in the case of two collected packets from different VRFs
but with the same source/destination IP, and same incoming/outgoing port, the VLAN fields is different
between the two samples. A VLAN/VE can only belong to one VRF. The collector does not have any
VRF knowledge, but based on the VLAN fields can distinguish which packet came from which VLAN/
VRF.
To configure an sFlow collector and specify a VRF, enter the following command:
Brocade(config)# sflow destination 10.10.10.vrf customer1
Brocade(config)#
Syntax: [no] sflow destination [ ipaddress | ipv6 ipv6-address ] [ udp-port-number ] [ vrf vrf-name ]
To disable the management VRF in sFlow, enter the following command:
Brocade(config)# sflow management-vrf disable
Brocade(config)#
Syntax: [no] sflow management-vrf-disable
To display sFlow configuration and statistics, enter the following command:
Brocade(config)# show sflow

Configuring static-ARP for Multi-VRFs
The interface associated to the ARP entry determines to which VRF the ARP entry belongs. An ARP
entry is defined by the following parameters:
• IP address
• MAC address
• Type
• Interface
