Table B-1. Allowable Primitives (Continued)
Primitive Explanation
ip6 proto protocol True if the packet is an IPv6 packet of protocol type protocol. This primitive does not
chase the protocol header chain.
ip6 protochain protocol True if the packet is IPv6 packet, and contains protocol header with type protocol in its
protocol header chain. For example, ip6 protochain 6
matches any IPv6 packet with TCP protocol header in the protocol header chain. The
packet may contain, for example, authentication header, routing header, or hop-by-
hop option header, between IPv6 header and TCP header. The BPF code emitted by
this primitive is complex and cannot be optimized by BPF optimizer code in tcpdump,
so this can be somewhat slow.
ip protochain protocol True if the packet contains protocol header with type protocol in its protocol header
chain.
For example, ip protochain 6 matches any IPv4 packet with TCP protocol header
in the protocol header chain. The packet can contain, for example, authentication
header, routing header, or hop-by-hop option header, between IPv4 header and TCP
header.
The BPF code emitted by this primitive is complex and cannot be optimized by BPF
optimizer code in tcpdump, so this can be somewhat slow.
ether broadcast True if the packet is an Ethernet broadcast packet. The ether keyword is optional.
ip broadcast True if the packet is an IP broadcast packet. It checks for both the all-zeroes and all-
ones broadcast conventions, and looks up the local subnet mask.
ether multicast True if the packet is an ethernet multicast packet. The ether keyword is optional. This
is shorthand for ether[0] & 1!= 0.
ip multicast True if the packet is an IP multicast packet.
ip6 multicast True if the packet is an IP6 multicast packet.
