... Today we spotted a peak of CPU usage for a Switching Processor. The peak can be correlated with a peak of inbound unicast on a port named "NDE_vlan1014" ... So the question is : what is this "NDE_vlan" interface ? NDE_vlan is one of the Catalyst 6500's hidden vlans. The 6500 allocates internal vlans for a lot of different functions, and those ...

I'm wondering why packets don't enter in the queue at all before being dropped. Because they were errors: 8097 input errors, 7120 CRC, 894 frame It will not queue a packet that wasn't received properly -- or wasn't received completely (input queue is in software, you can still overrun the hardware queue, which you cannot change)

Background I am somewhere that blocks Dropbox downloads, so I can't see the captured traffic, but I'll go on the assumption these were 64-byte ethernet multicasts. Let's do some math to see how much traffic you're permitting... A 64-byte frame is 672 bits (including 8 bytes for Preamble/SFD, and 12 bytes for IFG)... 8*(8 + 12 + 64) = 672 bits That means line ...

SSH on the 6500 series is a software feature, so the best thing to do is use the Cisco Feature Navigator to select a software image with SSH support and install that.

MUX-UNI support: It looks like you're trying to configure a MUX-UNI with: A Layer3 interface on Vlan 556 A Vlan-mode PW on Vlan 920 The WS-X6516A is considered a Catalyst 6500 / Cisco 7600 LAN Card; LAN cards have some feature restrictions... one of the restrictions is how you configure a Layer3 interface on a LAN card with dot1q encapsulation. When you'...

I would like to have the IOS: c7600s72033-advipservicesk9-mz.122-33.SRE1.bin running on the 7609 router. Is this IOS compatible with 6509, so I can update the IOS on the 6509 and then move the SUP? You're speaking about a subject which is very confusing, and I apologize. For years, you could mostly get away with saying the biggest difference between a ...

It depends on the specific line card. Some line cards have more intelligence and features than other line cards. With the line cards that support CEF on the card, you can enable distributed CEF.

I don't think there are any 10G linecards/modules for the CAT6500 that directly support SFP+ modules.

A line card swap is exceedingly simple. You'll need to make sure that the replacement card is the exact same model as the old one. You can certainly bring TAC on the call with you to do the swap if you want help. the configuration is saved in the running-config/startup-config, and will be applied to the new line card after your insert it and it boots up ...

At what point do you push Cisco for hardware or RAM replacement? Whenever you feel like you can't afford the risk of the HW being bad. Single-bit parity errors happen because Cisco used non-ECC memory in some components of the Supervisor. As long as an occasional 3-second SSO failover is tolerable, just roll with Cisco's recommendation, because solar ...

CRC errors tend to indicate a problem with the signal as it crosses the medium between devices. Where 1G was often much more resilient to minor issues, 10G can be very particular about the medium. For copper connections, this could indicate some sort of interference bleeding into the wire if you are not using shielded cable, or a problem with ground in ...

I see this in your output: 8097 input errors, 7120 CRC, 894 frame, 0 overrun, 0 ignored ^^^^ ^^^^ ^^^ This means you could have a faulty network interface card (NIC), cable, or driver.

I have read that SIP-400 and SPA are compatible with 6509 series switch. These SIP and SPA are used to terminate PPP sessions on 7600 routers. If i installed this SIP and SPA (SPA-5X1GE-V2 for example) on my 6509 chassis, could i configure the switch to terminate PPPoE sessions? In that case, which IOS would support this feature? The switch has SUP720-...

The 4500 does not support switching on the line card at all. All packets are received on the line card, travel over the backplane, reach the supervisor where the ASIC is located where they get switched, then travel over the backplane again to the linecard with the egress interface on the way out. The 6500 supports switching on the line card (aka distributed ...

Are you using CatOS by any chance? From Cisco Catalyst-6500's power management page Use of the CLI to Power Modules Up or Down You can issue one of these commands in order to power down a properly working module from the command-line interface (CLI): Catalyst OS (CatOS)— set module power down module_number Cisco IOS® Software— no power enable module slot

Sorry to say that this isn't a configurable item.

As I wrote in my comment, the problem is at the remote (from the 6509) end of one or both links. Based on your comment, this appears to have been the case (application problem).

Based on what you describe and tested I'd expect the slot on the chassis to be broken.
