Spurious interrupts on a 2821
in [Cisco]
|
From: Roel on 29 Jan 2007 15:41 Hi, For the 3rd time in a month I had a lot of 'spurious interrupts' on a 2821 with a HWIC-1ADSL running on IOS 12.4(11)T Advanced Enterprise Services: Jan 25 10:01:08: %HWIC_ADSL_BRI-7-NETSPURIOUSEVENT: HWIC_ADSL_BRI 1: Spurious network interrupt 0 happened, mask 3FF. Jan 25 10:01:08: %HWIC_ADSL_BRI-7-IRQSPURIOUSEVENT: HWIC_ADSL_BRI: Spurious IRQ1 interrupt 0 happened. Jan 25 10:01:40: %HWIC_ADSL_BRI-7-NETSPURIOUSEVENT: HWIC_ADSL_BRI 1: Spurious network interrupt 0 happened, mask 3FF. Jan 25 10:02:01: %HWIC_ADSL_BRI-7-IRQSPURIOUSEVENT: HWIC_ADSL_BRI: Spurious IRQ1 interrupt 0 happened. Jan 25 10:02:11: %HWIC_ADSL_BRI-7-NETSPURIOUSEVENT: HWIC_ADSL_BRI 1: Spurious network interrupt 0 happened, mask 3FF. Jan 25 10:02:33: %HWIC_ADSL_BRI-7-IRQSPURIOUSEVENT: HWIC_ADSL_BRI: Spurious IRQ1 interrupt 0 happened. Jan 25 10:02:43: %HWIC_ADSL_BRI-7-NETSPURIOUSEVENT: HWIC_ADSL_BRI 1: Spurious network interrupt 0 happened, mask 3FF. Jan 25 10:03:05: %HWIC_ADSL_BRI-7-IRQSPURIOUSEVENT: HWIC_ADSL_BRI: Spurious IRQ1 interrupt 0 happened. Jan 25 10:03:15: %HWIC_ADSL_BRI-7-NETSPURIOUSEVENT: HWIC_ADSL_BRI 1: Spurious network interrupt 0 happened, mask 3FF. Jan 25 10:03:47: %HWIC_ADSL_BRI-7-NETSPURIOUSEVENT: HWIC_ADSL_BRI 1: Spurious network interrupt 0 happened, mask 3FF. Jan 25 10:04:19: %HWIC_ADSL_BRI-7-NETSPURIOUSEVENT: HWIC_ADSL_BRI 1: Spurious network interrupt 0 happened, mask 3FF. Jan 25 10:04:19: %HWIC_ADSL_BRI-7-IRQSPURIOUSEVENT: HWIC_ADSL_BRI: Spurious IRQ1 interrupt 0 happened. Jan 25 10:04:51: %HWIC_ADSL_BRI-7-NETSPURIOUSEVENT: HWIC_ADSL_BRI 1: Spurious network interrupt 0 happened, mask 3FF. After this the router is completely unreachable. When I reset the router everything is OK again for a week or so. The only information I can find on the cisco website about this errormessages is that this are debug-messages only, and that no action is required: http://www.cisco.com/en/US/products/ps6441/products_system_message_guide_chapter09186a0080632f18.html#wp1011392 Any ideas? Can it be a bug in the IOS (HWIC-1ADSL is only supported in the T-train), or is the HWIC-1ADSL module the problem? Thanks in advance! Roel Koops

You don't actually have adebug enabled do you?

If everyting is working I would believe the documents. You don't actually have a debug enabled do you? Level 7 is the least significant message type. Very often cisco do know what they are doing.

Sorry, did not read the whole mesage carefully. On usenet you get more than you pay for:-) In that case it sounds like a bug. TAC or if you don't have that try different software. You could try stripping out non-essential config items and manually allocating buffers to reduce or eliminate failures and missed buffers, but you will have to be very lucky to fix it that way. If you want buffer sugegstions post sh buffers also check for general overload, what is the CPU? are there any drops, ignores, throttles? |
