Cisco Small Business ESW 500 Series and NAC

Unanswered Question
Mar 1st, 2010

Would anyone know if the ESW-540-24P switches will work with Cisco NAC Clean Access as they do with 3560 switches?

I have this problem too.

Or even if the Small Business series switches will work with any NAC solution?

Hello Sina,

the answer is negative at least at first look, actually etherswitch modules are equivalent to C3750 / C3560 that are listed

Feature navigator tool can be used for this search

search by feature:



NAC - L2 IPNetwork Admission Control (NAC) L2 IP extends NAC support to layer 2 switches and is intended to be deployed on Layer 2 Ethernet access ports at the network edge. The device to be validated must be attached to the L2 port within the first Layer 3 hop.  NAC L2 IP does not require 802.1x support on the hosts.  Performing posture validation at the edge maximizes the portion of the network which is protected by the access control, and allows posture validation to be performed within a VLAN.  NAC - L2 IP acts at the same point in the network as the NAC - L2 IEEE 802.1x feature, but uses different mechanisms to initiate posture validation, to carry the communication between host and authentication server, and to enforce the resulting access limitations.

the list of supported plaforms include several cisco switches but no HWIC series

It may be wise to open a Cisco TAC

802.1X port authentication is supported

so it is possible being a port of C3560/C3750 code to be able to support NAC at layer2

Hope to help
