hardware compression not working - cisco 2621xm

Two Cisco 2621xm routers, ppp encapsulation on serial interfaces (T1 modules), AIM-COMPRESS2 v2 installed on each router and detected by the IOS software (sh diag 0, sh pci aim), compression enabled using compress stac caim 0 and no fair-queue, same IOS version on both routers.

sh compress displays software compression not hardware!

Any ideea what could the problem be ?

Thanks,

Re: hardware compression not working - cisco 2621xm

It could be:

- Interface is shut down

- Old IOS-software (use 12.0(7) or later)

- Bugs: CSCdk15127 [1], CSCdr47841 [2]

- Wrong syntax when using stacker (use "ppp compress

stac", not "compress stac")

You might want to take a look at the WAN Compression FAQ [3].

Hope this helps. :-)
