tcpdump \- dump traffic on a network
.SH SYNOPSIS
@ -2045,14 +2045,6 @@ prefer to fix the program generating them rather than \fItcpdump\fP.
A packet trace that crosses a daylight savings time change will give
skewed time stamps (the time change is ignored).
.LP
Filter expressions that manipulate FDDI, Token Ring, or 802.11 headers
assume that all FDDI, Token Ring, and 802.11 packets are
SNAP-encapsulated Ethernet packets.
This is true for IP, ARP, and DECNET Phase IV, but is not true
for protocols such as ISO CLNS.
Therefore, the filter may inadvertently
accept certain packets that do not properly match the filter expression.
.LP
Filter expressions on fields other than those in Token Ring headers will
not correctly handle source-routed Token Ring packets.
