I will never buy another used WIC-1DSU-T1. There are too many counterfeits out there and it's hard to tell the difference. I bought several over the past few months and half of them have had problems. I'm tired of hassling with them, but it sounds like I might be in for more potential hassle if I go with the new WIC V2s.

FWIW, I've had nothing but great success with the 2811's/2821's (and 3845's) thus far. I've got a couple of the WIC-1DSU's, but mostly have VWIC-2MFT-T1's and they work flawlessly thus far. I have about 20 T1's in production using them.

They can be had on eBay for $170, so you might want to consider to swapping to those instead of switching platforms. Seems like the -V2's have more production problems than they're worth because they're new.

Only complaint I have thus far on the 28xx is that when you do a write mem it can cause ISIS adjacencies to flap if the hello-interval is set to minimal. Still need to get a ddts opened on that.

Dave,

That's a great idea. If you ask them to make it viewable then I'll be able to track the progress of these bugs. I'd like to use the 2811s and those WICs but now I'm wondering if I should cancel my order and stick with a 2620XM instead. Does anyone know if the V2 WICs are experiencing problems when used in the 2600XM series or does this just happen in the 2800 series routers?

Thanks, John

For the record.

If you have a case open and the bug is not viewable on CCO then ask the TAC engineer to make it viewable.

There are usually only two reasons a bug is not viewable on CCO.

a) PSIRT b) It was found internally in testing and was thought to only exist in images that were never released to customers. If it's determined it was in an image released to a customer the correct procedure is to modify that bug so it is visible on CCO with the correct enclosures (ie: Release-note).

...or there is a 3rd reason and someone just messed up.

Bottom line, if you encounter a bug not viewable on CCO that you are hitting ask them to make it viewable.

Concerning the WIC-1DSU-T1-V2 we have been ecperiencing many problems and have a TAC case opened. So far we have identifed twi issues

that

Cisco has bugs id's assigned to.

- WIC runs for 2 hours, 17 minutes then goes down - High number of T1 errors seen with V2 card, no errors seen on

same

line with V1 card

These are Cisco internal bugs so I can't provide a bug ID.

Though

these specific cases may not reflect your experiences me thinks

the

has multiple issues.

Open a case with the Cisco TAC. Since your 2811 is probably

pretty

new,

you shouldn't even need a service contract (yet). They'll send

you

replacement

WICs and test to figure out why your current ones failed.

So far, with the new 2811s, I have seen an instance where one customer bought a mix of six 2811 and 2821 routers, and six WIC-1DSU-T1-V2s,

only

to find

that three out of the six V2 WICs DID NOT WORK. The broken

three

ONLY worked

in slot 0, and often times the T1s did not work properly even in that instance (it would go down and a reload was the only way to bring it back up).

The good three WICs worked fine, in any slot. The kicker is

that

the six

WICs had _SEQUENTIAL_ serial numbers, so for half of them to be "bad" in the 2811s was definitely not expected. They seemed to work fine in 3600 and other older routers.

Same customer, same routers, they also had a problem with a 2811 that is even more worrisome. One 2811, on a particular T1, would not stay up, "Line protocol is down", unless you set hdlc keepalive to 13

something

else odd. Plug in a 2500 with external CSU or 2600 with a WIC

and

the T1

works just fine with completely default settings. Ironically, other 2811s work fine at this location with default settings. All

2811s

had

the same IOS images (not that there is much choice for these new boxes)

Yep, there are strange issues with these new boxes. Given

Cisco's

marketing

push, I would imagine most early adopters are using them

primarily

voice applications and not data T1s. Perhaps they were better debugged there.

All I have left is to say "Way to go Cisco!!" for the broken T1 technology - I know it's highly complicated, delicate, top precision work,

and

that the

utmost time and care goes into testing such obvious configurations...err..uhh.. wait a minute, what was I saying ???

Hello fellow Cisco-NSP folk.

I have a brand new 2811 router which according to the Cisco DPRG configurator is supposed to take the WIC-1DSU-T1-V2 modular WICs as opposed to the non-V2 type.

So we paid the higher price for brand-spanking-new V2 modules,

and

they

don't show up. "sho diag" gives:

WIC Slot 0: Unknown WAN daughter card WIC module not supported/disabled in this slot Hardware revision 64.0 Board revision >1 Serial number 1379991808 Part number 800-7441222-79 Test history 0x43 RMA number 48-55-51 Connector type PCI EEPROM format version 1 EEPROM contents (hex): 0x20: 01 80 40 00 52 41 01 00 C1 8B 46 4F 43 30 37 33 0x30: 31 31 41 36 4A 82 49 20 9A 03 42 41 30 03 00 81

Tried two different WICs in all slots with similar results.

Is there some magic needed to get these recognized or do I have

hardware

issue? The box is running IP-Base 12.3(11)T2, same results with 12.3(8)T.
