qos pre-classify, match protocol telnet

[Utair Corporation]

Was playing with qos pre-classify feature and found what:

class-map match-all CLASS

match protocol telnet

policy-map POLICY

class CLASS

  set dscp af11

!

!

interface tunnel0

qos pre-classify

...

tunnel source x.x.x.x

!
!

interface f0/0

ip address x.x.x.x ...

service-policy output POLICY

!

doesn't do anything

changing class-map like:

ip access-list ext 100

permit tcp any any eq telnet

class-map match-all CLASS

match access-group 100

makes it all working.

Is it bug or feature?

Tried on Cisco IOS Software, 3600 Software (C3660-JK9O3S-M), Version 12.4(15)T11, RELEASE SOFTWARE (fc2)

on virtual router (GNS3)

Hi,

seems like a limitation of the technology:  http://www.cisco.com/en/US/tech/tk543/tk757/technologies_tech_note09186a00800b3d15.shtml#sub2
