Due to the shared memory architecture of the M160, the bogus cells could be coming from any of the FPCs or the problem could be the SFM itself. Usually the problem is caused by an FPC in my experience.
To isolate the offending FPC, you can do the following steps: 1) reboot each FPC one at a time 2) look for any bchip (or bogus cell) errors reported in syslog during bootup This should expose the FPC that is introducing the bogus cells. But JTAC may have more commands they can run that may not require you to reboot the FPC's one by one if this router is a critical router. So I would recommend opening a case with them. -----Original Message----- From: Mario Andres Rueda Jaimes [mailto:[email protected]] Sent: Thursday, June 09, 2011 11:22 AM To: Devin Kennedy Cc: [email protected] Subject: RE: [j-nsp] M160 SFM BOGUS ERRORS Devin We are running junos 9,6R3.8 the messages seen once the SFM goes up, are like this Jun 9 13:58:16 fpc0 DCHIP(0/3): H/S link Tx12(0) overflow Jun 9 13:58:16 fpc0 DCHIP(0/3): H/S link Tx12(1) overflow Jun 9 13:58:16 fpc6 DCHIP(6/0): H/S link Tx12(1) overflow Jun 9 13:58:16 fpc6 DCHIP(6/0): H/S link Tx12(2) overflow Jun 9 13:58:19 fpc7 DCHIP(7/1): H/S link Tx12(0) overflow Jun 9 13:58:19 fpc0 DCHIP(0/3): H/S link Tx12(1) overflow Jun 9 13:58:20 fpc0 DCHIP(0/3): H/S link Tx12(0) overflow Jun 9 13:59:15 fpc6 DCHIP(6/0): H/S link Tx12(1) overflow right now only bogus errors are seen Regards -----Mensaje original----- De: Devin Kennedy <[email protected]> Para: 'Mario Andres Rueda Jaimes' <[email protected]>, [email protected] Asunto: RE: [j-nsp] M160 SFM BOGUS ERRORS Fecha: Thu, 9 Jun 2011 10:34:18 -0400 In my experience, these can be caused by either the SFM or one of the FPCs. In the messages log, do you see any B chip errors? What version of Junos? Usually this indicates a hardware issue and often requires an RMA of the faulty SFM or FPC. You should open a case with JTAC for this. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Mario Andres Rueda Jaimes Sent: Thursday, June 09, 2011 10:12 AM To: [email protected] Subject: [j-nsp] M160 SFM BOGUS ERRORS Hi All, We are getting following error messages on our M160 Router, there is no traffic impact, anyone can help with this ?
