Enable And Disable Sflow; Enable And Disable On An Interface - Dell Force10 C150 Configuration Manual

• FTOS exports all sFlow packets to the collector. A small sampling rate can equate to a large number of
exported packets. A backoff mechanism will automatically be applied to reduce this amount. Some
sampled packets may be dropped when the exported packet rate is high and the backoff mechanism is
about to or is starting to take effect. The dropEvent counter, in the sFlow packet, will always be zero.
• Community list and local preference fields are not filled in extended gateway element in sFlow
datagram.
• 802.1P source priority field is not filled in extended switch element in sFlow datagram.
• Only Destination and Destination Peer AS number are packed in the dst-as-path field in extended
gateway element
• If packet being sampled is redirected using PBR (Policy-Based Routing), sFlow datagram may contain
incorrect extended gateway/router information.
• Source VLAN field in the extended switch element will not be packed in case of routed packet.
• Destination VLAN field in the extended switch element will not be packed in case of Multicast packet.
• On the C-Series, Layer 3 and Layer 2 multicast traffic is not collected with sFlow sampling.
• On the S-Series, up to 700 packets can be sampled and processed per second.
• On the C-Series up to 1000 packets can be sampled and processed per second.
• On the E-Series, the maximum number of packets that can be sampled and processed per second is:
— 7500 packets when no extended information packing is enabled.
— 1000 packets when only extended-switch information packing is enabled.
— 1600 packets when extended-router and/or extended-gateway information packing is
