WebJan 13, 2024 · Netflow monitoring supports only the 7 keys—Source IP, Destination IP, Layer 3 protocol type, TOS, source port, destination port and input logical interface to identify or classify flows for both IPv4 and IPv6 unicast traffic. All other keys are not supported. WebYou can configure a firewall filter with match conditions for Internet Protocol version 6 (IPv6) traffic ( family inet6 ). Note: For MX Series routers with MPCs, you need to initialize the filter counter for Trio-only match filters by walking the corresponding SNMP MIB, for example, show snmp mib walk name ascii.

WebThe last Extension Header’s ‘Next-Header’ field point to Upper Layer Header. Thus all headers from point to the next one in a linked list manner. If the Next Header field contains value 59, it indicates that there’s no header after this header, not even Upper Layer Header. The following Extension Headers must be supported as per RFC 2460: Value 59 (No Next Header) in the Next Header field indicates that there is no next header whatsoever following this one, not even a header of an upper-layer protocol.
