Embedded Packet Capture on 3750-XI

[Gordon Ross]

I'm following the instructuions at https://supportforums.cisco.com/document/139686/configuration-example-embedded-packet-capture-cisco-ios-and-ios-xe to setup EPC on my 3750-X running IOS 15.0(2)SE2

In theory, it's all configured, but a "sh monitor capture buffer" shows the buffer is empty.

I did a google, and one search result said the EPC wasn't available for all catalysts, but as mine has the commands, I assume it should work.

On interface g1/0/6 I have the configuration:

interface GigabitEthernet1/0/6
 switchport access vlan 100
end

I also defined an ACL for this EPC:

ip access-list extended ACL-CAP
 permit ip host 192.168.0.1 any
 permit ip any host 192.168.0.1

I configured up the EPC as:

monitor capture buffer CAP1 size 2048 max-size 4000 linear
monitor capture buffer CAP1 filter access-list ACL-CAP
monitor capture point ip cef CAP_P1 vlan100 both
monitor capture point associate CAP_P1 CAP1
monitor capture point start CAP_P1

Suggetions as to what's wrong? (Or is it that it's not supported on the 3750-X?)

Hello Gordon,

Hope you are well.

I have searched high and low regarding EPC on 3750-X.

Looks to me that the feature is NOT supported on this product.

I did get it working on a new 3650 switch.

The feature documentation always seems to refer that the feature is only
available on "Routers".

I think some Cisco doc refreshes are required.

Looks to me like you will need to resort to SPAN & RSPAN
and hook up a monitoring port etc.
