To whom it may concern,
I recently attempted to use simple tc action pedit commands on the man
page and I ran into some errors. The following is some information
about my version of iproute and my machine:
----------------------------
the following is my iproute package information
Loaded plugins: fastestmirror, langpacks

---------------------------------------------------------------------------------
I am running the latest version of Centos 7 with kernel version:
3.10.0-514.26.2.el7.x86_64
-------------
The following are the first three commands of the man page that I run
and their output
---------------------------------------------------------------------------------
tc qdisc replace dev eth0 root handle 1: htb
tc qdisc add dev eth0 ingress handle ffff:
tc filter add dev eth0 parent 1: u32 \
> match ip dport 23 0xffff \
> action pedit pedit munge ip dport set 22
bad pedit parsing
Illegal pedit construct (ip)
Usage: ... pedit munge <MUNGE>
Where: MUNGE := <RAW>|<LAYERED>
<RAW>:= <OFFSETC>[ATC]<CMD>
OFFSETC:= offset <offval> <u8|u16|u32>
ATC:= at <atval> offmask <maskval> shift <shiftval>
NOTE: offval is byte offset, must be multiple of 4
NOTE: maskval is a 32 bit hex number
NOTE: shiftval is a is a shift value
CMD:= clear | invert | set <setval>| retain
<LAYERED>:= ip <ipdata> | ip6 <ip6data>
| udp <udpdata> | tcp <tcpdata> | icmp <icmpdata>
For Example usage look at the examples directory
bad action parsing
parse_action: bad value (7:pedit)!
Illegal "action"
---------------------------------------------
The first two commands run without error. However the third command fails.
It apparently does not recognize the ip command. This seems strange to
me since the commands I run are on the tc-pedit man page. Any help on
this issue would be appreciated.
Sincerely,
Tyler Bautista
