Ta b l e 3-79 Field Descriptions for the show statistics wccp gre Command
Field Description
Transparent GRE packets
received
Total number of GRE packets received by the WAE, regardless of
whether or not they have been intercepted by WCCP. GRE is a
Layer 3 technique that allows packets to reach the WAE, even if
there are any number of routers in the path to the WAE.
Transparent non-GRE packets
received
Number of non-GRE packets received by the WAE, either using
the traffic interception and redirection functions of WCCP in the
router hardware at Layer 2 or Layer 4 switching (a Content
Switching Module [CSM]) that redirects requests transparently to
the WAE.
Transparent non-GRE packets
passed through
Number of non-GRE packets transparently intercepted by a
Layer
4 switch and redirected to the WAE.
Total packets accepted Total number of packets that are transparently intercepted and
redirected to the WAE to serve client requests for content.
Invalid packets received Number of packets that are dropped either because the redirected
packet is a GRE packet and the WCCP GRE header has invalid
data or the IP header of the redirected packet is invalid.
Packets received with invalid
service
Number of WCCP version 2 GRE redirected packets that contain
an invalid WCCP service number.
Packets received on a disabled
service
Number of WCCP version 2 GRE redirected packets that specify
the WCCP service number for a service that is not enabled on the
WAE. For example, an HTTPS request redirected to the WAE
when the HTTPS-caching service (service 70) is not enabled.
Packets received too small Number of GRE packets redirected to the WAE that do not
contain the minimum amount of data required for a WCCP GRE
header.
Packets dropped due to zero TTL Number of GRE packets that are dropped by the WAE because the
redirected packet’s IP header has a zero TTL.
Packets dropped due to bad
buckets
Number of packets that are dropped by the WAE because the
WCCP flow redirection could not be performed due to a bad mask
or hash bucket determination.
Note A bucket is defined as a certain subsection of the allotted
hash assigned to each WAE in a WAE cluster. If only one
WAE exists in this environment, it has 256 buckets
assigned to it.
Packets dropped due to no redirect
address
Number of packets that are dropped because the flow redirection
destination IP address could not be determined.
Packets dropped due to loopback
redirect
Number of packets that are dropped by the WAE when the
destination IP address is the same as the loopback address.
Pass-through pkts dropped on
assignment update
Number of packets that were targeted for TFO pass-through, but
were dropped instead because the bucket was not owned by the
device.
