How to configure and verify IP compression on Aruba devices?
Requirement:

Aruba controllers support IP compression with certain hardware and topologies. In this article, we will see how to configure the same and verify it.

 



Solution:

Aruba Controller supports IP compression on ArubaOS 6.4.3.0 and above on controllers 7000 and 7200 series (except 7205).

 



Configuration:

IP compression is enabled by default in following topologies. There is no special configuration needed.

a. Master<==> Branch office Controller.

b. Master<==>Standby<==>Local controller.

 

We can disable it using the following commands:

(Aruba7005) #configure t
Enter Configuration commands, one per line. End with CNTL/Z
# crypto-local isakmp disable-ipcomp

 

We can enable it again using the command below:

(Aruba7005) (config) #no crypto-local isakmp disable-ipcomp

 



Verification

We can see the status of IP compression:

(Aruba7005) #show crypto-local isakmp disable-ipcomp
IP Compression is Enabled

 

We can verify the status on any Master-Local or Master-BOC controller:

(Aruba7005) #show role
switchrole:standby
masterip:10.150.2.100

(Aruba7005) #show datapath compression

We will see the above counters increase:
