!!! PDLM problems on 7200 !!!

[john.dean]

I have a TAC case open on this but I thought I would float it here, too.

IOSver advipservices 12.4.11T

platform 7200/NPE-G1

I am adding a pdlm for sap-app on a 7200.

when the pdlm is loaded (other than at boot time) some very bad things happen.

The symptom is that my configuration changes. e.g. in an existing class-map, a config line that previously said "match protocol eigrp" now says "match protocol ipinip"

I suspect that that nbar keeps a table of protocols in memory and adding the new pdlm causes the index to change resulting in these symptoms.

Anyone else seen this? If it is a known bug is there a code version where it is fixed?

Hi,

Yes, PDLMs are installed in a flash memory, Cisco routers and Switches do recognize PDLMs by looking into the Payload of the Data at the layer-3 header.

I am not exactly sure about this symbtoms, but it's strange because it identifies the application signature rather than TCP/IP port number.

Pls let us know the feedback from TAC,

HTH

DE made the situation worse by ignoring it...

Same bug has now surfaced on the 2800 platform in code c2800nm-advipservicesk9-mz.124-15.T4.bin.

I assume 3800 is similarly affected.
