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 50.
