Primitives Description

mpls [label_num] True if the packet is an MPLS packet

If [label_num] is specified, only true is the packet that has the specified

label_num

The first "mpls" keyword encountered in expression changes the

decoding offsets for the remainder of expression on the assumption

that the packet is a MPLS-encapsulated IP packet

The "mpls" "[label_num]expression may be used more than once, to

filter on MPLS hierarchies

Each use of that expression increments the filter offsets by 4

For example, “mpls 100000 && mpls 1024 “ filters packets with an outer

label of 100000 and an inner label of 1024, and “mpls && mpls 1024 &&

host 192.9.200.1” filters packets to or from 192.9.200.1 with an inner

label of 1024 and any outer label

pppoed True if the packet is a PPP-over-Ethernet Discovery packet (Ethernet

type 0x8863)

pppoes True if the packet is a PPP-over-Ethernet Session packet (Ethernet type

0x8864)

The first "pppoes" keyword encountered in expression changes the

decoding offsets for the remainder of expression on the assumption

that the packet is a PPPoE session packet

For example, “pppoes && ppp proto 0x21” filters IPv4 protocols

encapsulated in PPPoE

tcp, udp, icmp Abbreviations for: “ip proto p”, where “p” is one of the above protocols

iso proto protocol True if the packet is an OSI packet of protocol type protocol

Protocol can be a number or one of the names clnp, esis, or isis

clnp, esis, isis Abbreviations for: “iso proto p”, where “p” is one of the above

protocols
