Global default sampling rate: 32768Global default counter polling interval: 20Global extended information enabled: none0 collectors configured0 UDP packets exported0 UDP packets dropped0 sFlow samples collected0 sFlow samples dropped due to sub-samplingImportant Points to Remember• To export extended-gateway data, BGP must learn the IP destination address.• If the IP destination address is not learned via BGP the Dell Networking system does not exportextended-gateway data.• If the IP source address is learned via IGP, srcAS and srcPeerAS are zero.• The srcAS and srcPeerAS might be zero even though the IP source address is learned via BGP. The csystem packs the srcAS and srcPeerAS information only if the route is learned via BGP and it isreachable via the ingress interface of the packet.• The sFlow sampling functionality is supported only for egress traffic and not for ingress traffic.The previous points are summarized in following table.Table 48.
