Primitives Description
ether proto protocol True if the packet is of ether type protocol
Protocol can be a number or one of the names ip, ip6 ,arp, rarp, atalk,
aarp, sca, lat, mopdl, moprc, iso, stp, ipx, or netbeui
These identifiers are also keywords and must be escaped via backslash
(\)
In the case of Ethernet, WANFleX checks the Ethernet type field for
most of those protocols
The exceptions are:
iso, stp, and netbeui
WANFleX checks for an 802.3 frame and then checks the LLC
header as it does for FDDI, Token Ring, and 802.11
atalk
WANFleX checks both for the AppleTalk etype in an Ethernet
frame and for a SNAP-format packet as it does for FDDI, Token
Ring, and 802.11
aarp
WANFleX checks for the AppleTalk ARP etype in either an
Ethernet frame or an 802.2 SNAP frame with an OUI of 0x000000
ipx
WANFleX checks for the IPX etype in an Ethernet frame, the IPX
DSAP in the LLC header, the 802.3-with-no-LLC-header
encapsulation of IPX, and the IPX etype in a SNAP frame
ip, arp, rarp, atalk, aarp, iso, stp,
ipx, netbeui
Abbreviations for “ether proto p”, where “p” is one of the above
protocols
svlan [vlan_id] True if the packet is an IEEE 802.1Q Service VLAN packet (ether proto
0x88a8)
vlan [vlan_id] True if the packet is an IEEE 802.1Q VLAN packet (ether proto 0x8100)
If [vlan_id] is specified, only true if the packet has the specified vlan_id
The first "vlan" or "svlan" keyword encountered in expression changes
the decoding offsets for the remainder of expression on the assumption
that the packet is a VLAN packet
The "vlan" "[vlan_id]" expression may be used more than once, to filter
on VLAN hierarchies
Each use of that expression increments the filter offsets by 4
For example, “svlan 100 && vlan 200” filters on VLAN 200 encapsulated
within Service VLAN 100, and “vlan 300 && ip” filters IPv4 protocols
encapsulated in VLAN 300, and “svlan 100” filters all packets
encapsulated within Service VLAN 100
