[squid-users] wccp2 does not working

Dear All,

I am appreciate your expert advices on this matter :). I have tried
with following configuration but it is strange that WCCP2 is not
initiated the communication with Cisco Router. I were using this
configuration before, wccp2 was working fine.

Operation System: CentOS 6.4, x64 bits, Kernel 2.6.32-358.2.1.el6.x86_64

Below is my configuration:

1. Disk mount option
/dev/sdb1 /cache1 ext4
defaults,noatime,nodiratime,noacl,barrier=0,data=writeback,commit=100
      0 0
/dev/sdc1 /cache2 ext4
defaults,noatime,nodiratime,noacl,barrier=0,data=writeback,commit=100
      0 0
/dev/sdd1 /cache3 ext4
defaults,noatime,nodiratime,noacl,barrier=0,data=writeback,commit=100
      0 0
/dev/sde1 /cache4 ext4
defaults,noatime,nodiratime,noacl,barrier=0,data=writeback,commit=100
      0 0
/dev/sdf1 /cache5 ext4
defaults,noatime,nodiratime,noacl,barrier=0,data=writeback,commit=100
      0 0
/dev/sdg1 /cache6 ext4
defaults,noatime,nodiratime,noacl,barrier=0,data=writeback,commit=100
      0 0
/dev/sdh1 /cache7 ext4
defaults,noatime,nodiratime,noacl,barrier=0,data=writeback,commit=100
      0 0
/dev/sdi1 /cache8 ext4
defaults,noatime,nodiratime,noacl,barrier=0,data=writeback,commit=100
      0 0

2. Squid compiled option
Squid Cache: Version 3.3.3-20130318-r12517
configure options: '--sysconfdir=/etc/squid'
'--enable-follow-x-forwarded-for' '--enable-snmp'
'--enable-linux-netfilter' '--enable-http-violations'
'--enable-delay-pools' '--enable-storeio=diskd,aufs,ufs,rock'
'--with-large-files' '--enable-removal-policies=lru,heap'
'--enable-ltdl-convenience' '--with-logdir=/var/log/squid'
'--enable-wccpv2' '--with-default-user=squid'
'--enable-log-daemon-helpers' '--enable-build-info'
'--enable-url-rewrite-helpers' '--enable-async-io=128'

3. Squid Configuration

cache_dir aufs /cache8/squid/${process_number} 170000 16 256
min-size=31001 max-size=200000000
endif

I don't understand which directive impacted on WCCP2 protocol which
prevented it from establishing communication with the router.
So as result http traffic is not redirected to this squid server :(

May you help suggest me what else to check for the bug?
