Question about Multicast SAP format error

I have a network setup for pim-sparse ssm and autorp. ip sap listen was enabled on a 3750 (IOS advipservk9-m 12.2(35)SE2). I'm now receiving this error (%MROUTE-6-UNSUPPORTED_SAP_FORMAT: Received unsupported format SAP message from xxx.xxx.xxx.xxx) every second or so.

I've looked at output interpreter, but haven't seen any explanation from that tool other than "refer to output interpreter" :).

Anyone have any insight to this message? I don't see this message on my other switches (6500 series).

Thanks!

Re: Question about Multicast SAP format error

the message MROUTE-6-UNSUPPORTED_SAP_FORMAT is displayed when you receive a sap packet with compressed payload,

this is not supported
